[1]The Retail Class of the Fund has adopted a Distribution (12b-1) Plan that reimburses the Fund's distributor, Teachers Personal Investors Services, Inc. ("TPIS"), for its expenses in providing distribution, promotional and shareholder services to Retail Class shares at the annual rate of up to 0.25% of average daily net assets attributable to Retail Class shares.
[2]Under the Fund's expense reimbursement arrangements, the Fund's investment adviser, Teachers Advisors, Inc. ("Advisors"), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.96% of average daily net assets for Retail Class shares; (ii) 0.82% of average daily net assets for Retirement Class shares; (iii) 0.72% of average daily net assets for Premier Class shares; and (iv) 0.57% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 66% of the average value of its portfolio. During the six-month fiscal period ended March 31, 2011, the Fund’s portfolio turnover rate was 30% (not annualized) of the average value its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Under normal circumstances, the Fund invests at least 80% of its assets in the securities of companies that are principally engaged in or related to the real estate industry (“real estate securities”), including those that own significant real estate assets, such as real estate investment trusts (“REITs”). The Fund will invest primarily in equity securities of such companies. The Fund is actively managed using a research-oriented process with a focus on cash flows, asset values and Advisors’ belief in management’s ability to increase shareholder value. The Fund does not invest directly in real estate. The Fund concentrates its investments in the real estate industry. From time to time, the Fund may also invest in debt securities of companies principally engaged in or related to the real estate industry. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.


An issuer is principally “engaged in” or principally “related to” the real estate industry if at least 50% of its assets, gross income or net profits are attributable to ownership, construction, management or sale of residential, commercial or industrial real estate, or to products or services related to the real estate industry. The Fund typically invests in securities issued by equity REITs (which directly own real estate), mortgage REITs (which make short-term construction or real estate development loans or invest in long-term mortgages or mortgage pools), real estate brokers and developers, homebuilders, companies that manage real estate and companies that own substantial amounts of real estate. Businesses related to the real estate industry include manufacturers and distributors of building supplies and financial institutions that make or service mortgage loans.


The Fund also may invest up to 15% of its assets in real estate securities of foreign issuers and up to 20% of its assets in equity (including preferred stock) and debt securities of issuers that are not engaged in or related to the real estate industry. The benchmark index for the Fund is the FTSE NAREIT All Equity REITs Index.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, due to the nature of the Fund’s portfolio holdings, typically is subject to the following principal investment risks:


· Real Estate Investing Risk—As a result of the Fund’s investment objective, the Fund is subject to all of the risks associated with the ownership of real estate. These risks include, among others, declines in the value of real estate, negative changes in the climate for real estate, risks related to general and local economic conditions, decreases in property revenues, increases in prevailing interest rates, property taxes and operating expenses, changes in zoning laws and costs resulting from the cleanup of environmental problems.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Market Risk—The risk that market prices of investments held by the Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Industry Concentration Risk—Because the Fund concentrates its investments in only one industry and holds securities of relatively few issuers, the value of its portfolio is likely to experience greater fluctuations and may be subject to greater risk than those of other funds.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.

There can be no assurances that the Fund will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Institutional Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Institutional Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Institutional Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Institutional Class, Retirement Class, Premier Class and Retail Class over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of the Fund’s benchmark index. After-tax performance is shown only for Institutional Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Institutional Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The benchmark index listed below is unmanaged, and you cannot invest directly in the index. The returns for the index reflect no deduction for fees, expenses or taxes.

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 216% of the average value of its portfolio. During the six-month fiscal period ended March 31, 2011, the Fund’s portfolio turnover rate was 161% (not annualized) of the average value its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Under normal circumstances, the Fund invests at least 80% of its assets in bonds. For these purposes, bonds include fixed-income securities of all types. The Fund primarily invests in a broad range of investment-grade bonds and fixed-income securities, including, but not limited to, U.S. Government securities, corporate bonds and mortgage-backed or other asset backed-securities. The Fund may also invest in other fixed-income securities, including those of non-investment grade quality. The Fund does not rely exclusively on rating agencies when making investment decisions. Instead, the Fund’s investment adviser, Teachers Advisors, Inc. (“Advisors”), performs its own credit analysis, paying particular attention to economic trends and other market events. Individual securities or sectors are then overweighted or underweighted relative to the Fund’s benchmark index, the Barclays Capital U.S. Aggregate Bond Index, when Advisors believes that the Fund can take advantage of what appear to be undervalued, overlooked or misunderstood issuers that offer the potential to boost returns above that of the index. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.


Although the Fund may invest in fixed-income securities of any maturity, the duration of the Fund’s portfolio typically ranges within 15% of the duration of its benchmark index. As of March 31, 2011, the duration of the index was 5.01 years.


The Fund’s investments in mortgage-backed securities can include pass-through securities sold by private, governmental and government-related organizations and collateralized mortgage obligations (“CMOs”). Mortgage pass-through securities are created when mortgages are pooled together and interests in the pool are sold to investors. The cash flow from the underlying mortgages is “passed through” to investors in periodic principal and interest payments. CMOs are obligations that are fully collateralized directly or indirectly by a pool of mortgages from which payments of principal and interest are dedicated to the payment of principal and interest on the CMO.


The Fund may use an investment strategy called “mortgage rolls” (also referred to as “dollar rolls”), in which the Fund sells securities for delivery in the current month and simultaneously contracts with a counterparty to repurchase similar (same type, coupon and maturity) but not identical securities on a specified future date. The Fund loses the right to receive principal and interest paid on the securities sold. However, the Fund would benefit to the extent of any price received for the securities sold and the lower forward price for the future purchase (often referred to as the “drop”) plus the interest earned on the short-term investment awaiting the settlement date of the forward purchase. If such benefits exceed the income and gain or loss due to mortgage repayments that would have been realized on the securities sold as part of the mortgage roll, the use of this technique will enhance the investment performance of the Fund compared with what such performance would have been without the use of mortgage rolls. Realizing benefits from the use of mortgage rolls depends upon the ability of Advisors to predict correctly mortgage prepayments and interest rates.


The Fund may also engage in relative value trading, a strategy in which the Fund reallocates assets across different sectors and maturities. Relative value trading is designed to enhance the Fund’s returns but increases the Fund’s portfolio turnover rate.


The Fund may purchase and sell futures, options, swaps and other fixed-income derivative instruments to carry out the Fund’s investment strategies. The Fund may also invest in foreign securities, including emerging markets fixed-income securities and non-dollar denominated instruments. Under most circumstances, the Fund’s investments in fixed-income securities of foreign issuers constitute less than 20% of the Fund’s assets.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, due to the nature of the Fund’s portfolio holdings, typically is subject to the following principal investment risks:


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing the Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing the Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in the Fund’s income.


· Fixed-Income Foreign Investment Risk—Investment in fixed-income securities or financial instruments of foreign issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic developments. These developments may impact the ability of a foreign debt issuer to make timely and ultimate payments on its debt obligations to the Fund or impair the Fund’s ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for the Fund to properly value its investments and that the Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Mortgage Roll Risk—The risk that Advisors will not correctly predict mortgage prepayments and interest rates, which will diminish the Fund’s performance.


· Downgrade Risk—The risk that securities are subsequently downgraded should Advisors and/or rating agencies believe the issuer’s business outlook or creditworthiness has deteriorated.


· Non-Investment-Grade Securities Risk—Issuers of non-investment-grade securities, which are usually called “high-yield” or “junk bonds,” are typically in weaker financial health and such securities can be harder to value and sell and their prices can be more volatile. While these securities generally have higher rates of interest, they also involve greater risk of default than do securities of a higher-quality rating.


· Illiquid Investments Risk—The risk that illiquid investments may be difficult to sell for their fair market value.


· Derivatives Risk—The risks associated with investing in derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments. The Fund may use futures and options, and the Fund may also use more complex derivatives such as swaps that might present liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested.

There can be no assurances that the Fund will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 158% of the average value of its portfolio. During the six-month fiscal period ended March 31, 2011, the Fund’s portfolio turnover rate was 99% (not annualized) of the average value its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Under normal circumstances, the Fund invests at least 80% of its assets in bonds. For these purposes, bonds include fixed-income securities of all types. The Fund’s portfolio is divided into two segments. The first segment, which makes up at least 70% of the Fund’s assets, is invested primarily in a broad range of investment-grade bonds and fixed-income securities, including, but not limited to, corporate bonds, U.S. Treasury and agency securities and mortgage-backed and asset-backed securities. The securities within the Fund’s first segment are mainly high-quality instruments rated in the top four credit categories by Moody’s or S&P, or deemed to be of the same quality by Advisors using its own credit analysis. The second segment, which will not exceed 30% of the Fund’s assets, is invested in fixed-income securities and bonds with special features in an effort to improve the Fund’s total return. Potential investments in this segment include, but are not limited to, non-investment-grade securities (those rated Ba1 or lower by Moody’s or BB+ or lower by S&P), emerging market fixed-income securities and convertible and preferred securities. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.


Although the Fund may invest in fixed-income securities of any maturity, the duration of the Fund’s portfolio typically ranges within 15% of the duration of its benchmark index, the Barclays Capital U.S. Aggregate Bond Index. As of March 31, 2011, the duration of the index was 5.01 years.


The Fund’s investments in mortgage-backed securities can include pass-through securities sold by private, governmental and government-related organizations and collateralized mortgage obligations (“CMOs”). Mortgage pass-through securities are created when mortgages are pooled together and interests in the pool are sold to investors. The cash flow from the underlying mortgages is “passed through” to investors in periodic principal and interest payments. CMOs are obligations that are fully collateralized directly or indirectly by a pool of mortgages from which payments of principal and interest are dedicated to the payment of principal and interest on the CMO.


The Fund may use an investment strategy called “mortgage rolls” (also referred to as “dollar rolls”), in which the Fund sells securities for delivery in the current month and simultaneously contracts with a counterparty to repurchase similar (same type, coupon and maturity) but not identical securities on a specified future date. The Fund loses the right to receive principal and interest paid on the securities sold. However, the Fund would benefit to the extent of any price received for the securities sold and the lower forward price for the future purchase (often referred to as the “drop”) plus the interest earned on the short-term investment awaiting the settlement date of the forward purchase. If such benefits exceed the income and gain or loss due to mortgage repayments that would have been realized on the securities sold as part of the mortgage roll, the use of this technique will enhance the investment performance of the Fund compared with what such performance would have been without the use of mortgage rolls. Realizing benefits from the use of mortgage rolls depends upon the ability of Advisors to predict correctly mortgage prepayments and interest rates.


The Fund may also engage in relative value trading, a strategy in which the Fund reallocates assets across different sectors and maturities. Relative value trading is designed to enhance the Fund’s returns but increases the Fund’s portfolio turnover rate. The Fund may purchase and sell futures, options, swaps and other fixed-income derivative securities and financial instruments to carry out the Fund’s investment strategies.


The Fund can also invest in foreign securities, including emerging market fixed-income securities and non-dollar-denominated instruments, but Advisors does not expect them to exceed 20% of the Fund’s assets. No more than 15% of the Fund’s assets can be invested in illiquid securities.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, due to the nature of the Fund’s portfolio holdings, typically is subject to the following principal investment risks:


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing the Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing the Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in the Fund’s income.


· Fixed-Income Foreign Investment Risk—Investment in fixed-income securities or financial instruments of foreign issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic developments. These developments may impact the ability of a foreign debt issuer to make timely and ultimate payments on its debt obligations to the Fund or impair the Fund’s ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for the Fund to properly value its investments and that the Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Mortgage Roll Risk—The risk that Advisors will not correctly predict mortgage prepayments and interest rates, which will diminish the Fund’s performance.


· Downgrade Risk—The risk that securities are subsequently downgraded should Advisors and/or rating agencies believe the issuer’s business outlook or creditworthiness has deteriorated.


· Non-Investment-Grade Securities Risk—Issuers of non-investment-grade securities, which are usually called “high-yield” or “junk bonds,” are typically in weaker financial health and such securities can be harder to value and sell and their prices can be more volatile. While these securities generally have higher rates of interest, they also involve greater risk of default than do securities of a higher-quality rating.


· Illiquid Investments Risk—The risk that illiquid investments may be difficult to sell for their fair market value.


· Derivatives Risk—The risks associated with investing in derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments. The Fund may use futures and options, and the Fund may also use more complex derivatives such as swaps that might present liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested.

There can be no assurances that the Fund will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Institutional Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Institutional Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Institutional Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Institutional Class, Retirement Class, Premier Class and Retail Class over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of the Fund’s benchmark index. After-tax performance is shown only for Institutional Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Institutional Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The benchmark index listed below is unmanaged, and you cannot invest directly in the index. The returns for the index reflect no deduction for fees, expenses or taxes.

Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 95% of the average value of its portfolio. During the six-month fiscal period ended March 31, 2011, the Fund’s portfolio turnover rate was 93% (not annualized) of the average value its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Under normal circumstances, the Fund invests at least 80% of its assets in U.S. Treasury and agency securities and investment-grade fixed-income investments with an average maturity or average lives of less than 5 years. The Fund may overweight or underweight individual securities or sectors as compared to their weight in the index when Advisors finds undervalued or overlooked issues that it believes offer the potential for superior returns. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.


Although the Fund may invest in fixed-income securities of any maturity, the duration of the Fund’s portfolio typically ranges within 15% of the duration of its benchmark index, the Barclays Capital 1-5 Year U.S. Government Credit Index. As of March 31, 2011, the duration of the index was 2.55 years. The Fund also has a policy of maintaining a dollar weighted average maturity of portfolio holdings of no more than three years.


The Fund may purchase and sell futures, options, swaps and other fixed-income derivative instruments to carry out the Fund’s investment strategies.


The Fund may invest in foreign securities, including emerging markets fixed-income securities and non-dollar denominated instruments. Under most circumstances, the Fund’s investments in fixed-income securities of foreign issuers constitute less than 20% of the Fund’s assets.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, due to the nature of the Fund’s portfolio holdings, typically is subject to the following principal investment risks:

· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in the Fund’s income.

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 109% of the average value of its portfolio. During the six-month fiscal period ended March 31, 2011, the Fund’s portfolio turnover rate was 43% (not annualized) of the average value its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests primarily in lower-rated, higher-yielding fixed-income securities, such as domestic and foreign corporate bonds, debentures, loan participations and assignments and notes, as well as convertible securities and preferred stocks. Under normal circumstances, the Fund invests at least 80% of its assets in debt and other fixed-income securities rated lower than investment-grade (and their unrated equivalents) or other high-yielding debt securities. (These are often called “junk” bonds.) Most of these will be securities rated in the BB or B categories by S&P, or the Ba or B categories by Moody’s. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.


The Fund may invest up to 20% of its assets in the following types of instruments: payment-in-kind or deferred-interest obligations, defaulted securities, asset-backed securities, securities rated lower than B- or its equivalent by at least two rating agencies and securities having limited liquidity.


The Fund can make foreign investments, including investments in emerging market countries, but the Fund does not expect them to be over 20% of its assets. The Fund can have up to 15% of its assets in illiquid securities. The Fund can also invest in U.S. Treasury and agency securities or other short-term instruments when other suitable investment opportunities are not available, or when Advisors would like to build the Fund’s liquidity.


Over long periods of time, a broadly diversified portfolio of lower-rated, higher-yielding securities is designed to, net of capital losses, provide a higher net return than a similarly diversified portfolio of higher-rated, lower-yielding securities of similar duration. Advisors attempts to minimize the risks of investing in lower-rated securities by:


 Doing its own credit analysis (independent of the rating agencies). The Fund will buy securities of issuers with a balance of operational and financial risks that Advisors believes make it likely that such issuers will be able to meet their financial obligations;


 Constructing a portfolio of securities diversified by industry, maturity, duration and credit quality; and


 Buying or selling particular securities to take advantage of anticipated changes and trends in the economy and financial markets.


Advisors’ judgment of the value of any particular security is a function of its experience with lower-rated securities, evaluation of general economic and securities market conditions and the financial condition of the security’s issuer.


Under some market conditions, the Fund may sacrifice potential yield in order to adopt a defensive posture designed to preserve capital.


The Fund may purchase and sell futures, options, swaps and other fixed-income derivative securities and financial instruments to carry out the Fund’s investments strategies.


The benchmark index for the Fund is the BofA Merrill Lynch BB-B U.S. Cash Pay High Yield Constrained Index.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, due to the nature of the Fund’s portfolio holdings, typically is subject to the following principal investment risks:


· Non-Investment-Grade Securities Risk—Issuers of non-investment-grade securities, which are usually called “high-yield” or “junk bonds,” are typically in weaker financial health and such securities can be harder to value and sell and their prices can be more volatile. While these securities generally have higher rates of interest, they also involve greater risk of default than do securities of a higher-quality rating.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in the Fund’s income.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for the Fund to properly value its investments and that the Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Fixed-Income Foreign Investment Risk—Investment in fixed-income securities or financial instruments of foreign issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic developments. These developments may impact the ability of a foreign debt issuer to make timely and ultimate payments on its debt obligations to the Fund or impair the Fund’s ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Derivatives Risk—The risks associated with investing in derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments. The Fund may use futures and options, and the Fund may also use more complex derivatives such as swaps that might present liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested.

There can be no assurances that the Fund will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Institutional Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Institutional Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Institutional Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Institutional Class, Retirement Class, Premier Class and Retail Class over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of the Fund’s benchmark index. After-tax performance is shown only for Institutional Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Institutional Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The benchmark index listed below is unmanaged, and you cannot invest directly in the index. The returns for the index reflect no deduction for fees, expenses or taxes.

Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 29% of the average value of its portfolio. During the six-month fiscal period ended March 31, 2011, the Fund’s portfolio turnover rate was 11% (not annualized) of the average value its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Under normal circumstances, the Fund invests at least 80% of its assets in tax-exempt bonds, a type of municipal security, the interest on which, in the opinion of the issuer’s bond counsel at the time of issuance, is exempt from federal income tax, including federal alternative minimum tax (“AMT”). The Fund may also invest in other municipal securities including bonds, notes, commercial paper and other instruments (including participation interests in such securities) issued by or on behalf of the states, territories and possessions of the United States (including the District of Columbia) and their political subdivisions, agencies and instrumentalities, the interest on which, in the opinion of bond counsel for the issuers at the time of issuance, is exempt from regular federal income tax (i.e., excludable from gross income for individuals for federal income tax purposes but not necessarily exempt from AMT). Some of these securities may also be exempt from certain state and local income taxes. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.


Municipal securities are often issued to raise funds for various public purposes, including the construction of a wide range of public facilities such as bridges, highways, housing, hospitals, mass transportation facilities, schools, streets and public utilities such as water and sewer works.


The Fund may invest up to 20% of its assets in private activity bonds. Private activity bonds are tax-exempt bonds whose proceeds are used to finance private, for-profit organizations. The interest on these securities (including the Fund’s distribution of that interest) may be a preference item for purposes of the AMT. The AMT is a special tax system that ensures that individuals and certain corporations pay at least some federal taxes. Income from securities that are a preference item is included in the computation of the AMT.


The Fund can also invest in other municipal securities, including certificates of participation, municipal leases, municipal obligation components and municipal custody receipts. In addition, the Fund can invest in municipal bonds secured by mortgages on single-family homes and multi-family projects. The Fund’s investments in these securities are subject to prepayment and extension risk. All of the Fund’s assets are dollar-denominated securities.


The Fund may invest up to 20% of its assets in securities rated below investment-grade, or unrated securities of comparable quality, which are usually called “junk” bonds.


The Fund pursues superior returns using historical yield spread and credit analysis to identify and invest in undervalued market sectors and individual securities. The Fund usually sells investments that Advisors believes to be overvalued on a relative basis. Although the Fund may invest in fixed-income securities of any maturity, the duration of the Fund’s portfolio typically ranges within 15% of the duration of its benchmark index, the Barclays Capital 10-Year Municipal Bond Index. As of March 31, 2011, the duration of the index was 7.46 years.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, due to the nature of the Fund’s portfolio holdings, typically is subject to the following principal investment risks:


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· State and Municipal Investment Risk—Because the Fund invests significantly in tax-exempt bonds and other municipal securities, events affecting states and municipalities may adversely affect the Fund’s investments and its performance. These events may include severe financial difficulties and continued budget deficits, economic or political policy changes, tax base erosion, state constitutional limits on tax increases, and changes in the credit ratings assigned to state and municipal issuers of debt instruments.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for the Fund to properly value its investments and that the Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Illiquid Investments Risk—The risk that illiquid investments may be difficult to sell for their fair market value.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in the Fund’s income.


· Non-Investment-Grade Securities Risk—Issuers of non-investment-grade securities, which are usually called “high-yield” or “junk bonds,” are typically in weaker financial health and such securities can be harder to value and sell and their prices can be more volatile. While these securities generally have higher rates of interest, they also involve greater risk of default than do securities of a higher-quality rating.

There can be no assurances that the Fund will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 12% of the average value of its portfolio. During the six-month fiscal period ended March 31, 2011, the Fund’s portfolio turnover rate was 7% (not annualized) of the average value its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Under normal circumstances, the Fund invests at least 80% of its assets in fixed-income securities whose principal value increases or decreases based on changes in the Consumer Price Index for All Urban Consumers (“CPI-U”), over the life of the security. Typically, the Fund will invest in U.S. Treasury Inflation-Indexed Securities (“TIIS”). The Fund can also invest in (1) other inflation-indexed bonds issued or guaranteed by the U.S. Government or its agencies, by corporations and other U.S. domiciled issuers, as well as foreign governments, and (2) money market instruments or other short-term securities. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.


Like conventional bonds, inflation-indexed bonds generally pay interest at fixed intervals and return the principal at maturity. Unlike conventional bonds, an inflation-indexed bond’s principal or interest is adjusted periodically to reflect changes in a specified inflation index. Inflation-indexed bonds are designed to preserve purchasing power over the life of the bond while paying a “real” rate of interest (i.e., a return over and above the inflation rate). These bonds are generally issued at a fixed interest rate that is lower than that of conventional bonds of comparable maturity and quality, but they generally retain their value against inflation over time.


The principal amount of a TIIS bond is adjusted periodically for inflation using the CPI-U. Interest is paid twice a year. The interest rate is fixed, but the amount of each interest payment varies as the principal is adjusted for inflation. The principal amount of a TIIS instrument may diminish in times of deflation. However, the U.S. Treasury guarantees that the final principal payment at maturity is at least the original principal amount of the bond. The interest and principal components of the bonds may be “stripped” or sold separately. The Fund can buy or sell either component.


The Fund may also invest in inflation-indexed bonds issued or guaranteed by foreign governments and their agencies, as well as other foreign issuers. These investments are usually designed to track the inflation rate in the issuing country. Under most circumstances, the Fund’s investments in inflation-linked bonds of foreign issuers is generally less than 25% of its assets.


The Fund is managed to maintain a duration that is similar to its benchmark index, the Barclays Capital U.S. Treasury Inflation-Protected Securities (TIPS) Index (Series-L). Typically, the Fund invests in corporate and foreign inflation-indexed bonds that are similar in duration and maturity as those of U.S. Government inflation-indexed bonds.


The Fund may purchase and sell futures, options, swaps and other fixed-income derivative instruments to carry out the Fund’s investment strategies. The Fund also may invest in any fixed-income securities provided that no more than 5% of its assets are invested in fixed-income securities rated below investment-grade.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, due to the nature of the Fund’s portfolio holdings, typically is subject to the following principal investment risks:


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Fixed-Income Foreign Investment Risk—Investment in fixed-income securities or financial instruments of foreign issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic developments. These developments may impact the ability of a foreign debt issuer to make timely and ultimate payments on its debt obligations to the Fund or impair the Fund’s ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Derivatives Risk—The risks associated with investing in derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments. The Fund may use futures and options, and the Fund may also use more complex derivatives such as swaps that might present liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested.

There can be no assurances that the Fund will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 66% of the average value of its portfolio. During the six-month fiscal period ended March 31, 2011, the Fund’s portfolio turnover rate was 87% (not annualized) of the average value its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Under normal circumstances, the Fund invests at least 80% of its assets in bonds within its benchmark and portfolio tracking index, the Barclays Capital U.S. Aggregate Bond Index (the “Index”). The Fund uses a sampling technique to create a portfolio that closely matches the overall investment characteristics of the Index (for, example, duration, sector diversification and credit quality) without investing in all of the securities in its index. At times the Fund may purchase securities not held in the Index, but which Advisors believes have similar investment characteristics to securities held in its index. Generally, the Fund intends to invest in a wide spectrum of public, investment-grade, taxable debt securities denominated in U.S. dollars including government securities, as well as mortgage-backed, commercial mortgage-backed and asset-backed securities. The Fund’s investments in mortgage-backed securities may include pass-through securities sold by private, governmental and government-related organizations and collateralized mortgage obligations, to the extent that such instruments are held by the Index. The Fund generally will invest in foreign securities denominated in U.S. dollars only to the extent they are included or eligible to be included in the Index. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.


The securities purchased by the Fund will mainly be high-quality instruments rated in the top four credit categories by Moody’s or S&P or deemed to be of the same quality by Advisors using its own credit quality analysis. The Fund may continue to hold instruments that were rated as high-quality when purchased, but which subsequently are downgraded to below-investment-grade status or have their ratings withdrawn by one or more ratings agencies.


Because the return of the Index is not reduced by investment and other operating expenses, the Fund’s ability to match the Index is negatively affected by the costs of buying and selling securities, as well as other fees and expenses. The use of this index by the Fund is not a fundamental policy of the Fund and may be changed without shareholder approval.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, due to the nature of the Fund’s portfolio holdings, typically is subject to the following principal investment risks:


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in the Fund’s income.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for the Fund to properly value its investments and that the Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing the Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing the Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Index Risk—The risk that the Fund’s performance will not correspond to its benchmark index for any period of time and may underperform such index or the overall stock market. Additionally, to the extent that the Fund’s investments vary from the composition of its benchmark index, the Fund’s performance could potentially vary from the index’s performance to a greater extent than if the Fund merely attempted to replicate the index.


· Fixed-Income Foreign Investment Risk—Investment in fixed-income securities or financial instruments of foreign issuers involves increased risks due to adverse issuer, political, regulatory, currency, market or economic developments. These developments may impact the ability of a foreign debt issuer to make timely and ultimate payments on its debt obligations to the Fund or impair the Fund’s ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.

There can be no assurances that the Fund will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Institutional Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Institutional Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Institutional Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Institutional Class, Retirement Class, Premier Class and Retail Class over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of the Fund’s benchmark index. After-tax performance is shown only for Institutional Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Institutional Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The benchmark index listed below is unmanaged, and you cannot invest directly in the index. The returns for the index reflect no deduction for fees, expenses or taxes.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests in high-quality, short-term money market instruments. Generally, the Fund seeks to maintain a share value of $1.00 per share. The Fund’s investments will be made in accordance with the applicable rules governing the quality, maturity and diversification of securities and other instruments held by money market funds.


The Fund invests in debt obligations with a remaining maturity of 397 days or less, such as:


(1) Commercial paper (short-term “IOUs” issued by corporations and others) or variable-rate, floating-rate or variable-amount securities of domestic or foreign companies;


(2) Obligations of commercial banks, savings banks, savings and loan associations, and foreign banks whose latest annual financial statements show more than $1 billion in assets. These include certificates of deposit, time deposits, bankers’ acceptances and other short-term debt;


(3) Securities issued by, or whose principal and interest are guaranteed by, the U.S. Government or one of its agencies or instrumentalities;


(4) Other debt obligations issued by domestic or foreign companies;


(5) Repurchase agreements involving securities issued or guaranteed by the U.S. Government or one of its agencies or instrumentalities, or involving certificates of deposit, commercial paper or bankers’ acceptances;


(6) Obligations issued or guaranteed by foreign governments or their political subdivisions, agencies or instrumentalities; and/or


(7) Obligations of international organizations (and related government agencies) designated or supported by U.S. or foreign government agencies to promote economic development or international banking.


The Fund maintains a dollar-weighted average maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less. The Fund limits its investments to securities that present minimal credit risk and are rated in the highest rating categories for short-term instruments. The Fund will only purchase money market instruments that at the time of purchase are “First Tier Securities,” that is, instruments rated within the highest short-term rating category by at least two nationally recognized statistical rating organizations (“NRSROs”), or rated within the highest short-term rating category by one NRSRO if it is the only NRSRO to have issued a rating for the security, or unrated securities of comparable quality or “Government Securities” as such term is defined by the applicable rules governing money market funds. The Fund can also invest up to 30% of its assets in money market and debt instruments of foreign issuers denominated in U.S. dollars.


The above list of investments is not exclusive and the Fund may make other investments consistent with its investment objective and policies.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, due to the nature of the Fund’s portfolio holdings, typically is subject to the following principal investment risks:


· Current Income Risk—The risk that the income the Fund receives may fall as a result of a decline in interest rates. In a low interest rate environment, the Fund may not be able to achieve a positive or zero yield or maintain a stable net asset value of $1.00 per share.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for the Fund to properly value its investments and that the Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Credit Risk (a type of Company Risk)—The risk that a decline in a company’s financial position may prevent it from making principal and interest payments on fixed-income securities when due.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Fixed-Income Foreign Investment Risk—Investment in fixed-income securities or financial instruments of foreign issuers involves increased risks due to adverse issuer, political, regulatory, market or economic developments. These developments may impact the ability of a foreign debt issuer to make timely and ultimate payments on its debt obligations to the Fund or impair the Fund’s ability to enforce its rights against the foreign debt issuer. These risks are heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.

Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund. There can be no assurances that the Fund will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Institutional Class of the Fund, before taxes, in each full calendar year for the last ten years. Because the expenses vary across share classes, the performance of the Institutional Class will vary from the other share classes.

[1]The Retail Class of the Fund has adopted a Distribution (12b-1) Plan that reimburses the Fund's distributor, Teachers Personal Investors Services, Inc. ("TPIS"), for its expenses in providing distribution, promotional and/or shareholder services to Retail Class shares at the annual rate of up to 0.25% of average daily net assets attributable to Retail Class shares.

In addition, TPIS has contractually agreed not to seek payment of this fee under the Plan for Retirement Class shares through September 30, 2012, unless changed with approval of the Board of Trustees.
[2]"Acquired Fund Fees and Expenses" are the Fund's proportionate amount of the expenses of any investment companies or pools in which it invests. These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly because they reduce Fund performance. Because "Acquired Fund Fees and Expenses" are included in the chart above, the Fund's operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund's May 31, 2011 annual report.

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 33% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 7% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). The Fund invests in Underlying Funds according to a relatively stable asset allocation strategy that will not gradually adjust over time and is designed for investors who are already in or entering retirement (i.e., have already passed their retirement year).


The Fund expects to allocate approximately 40.00% of its assets to equity Underlying Funds and 60.00% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations may be changed and actual allocations may vary up to 10% from the targets. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income, short-term fixed-income and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which may change, are approximately as follows: U.S. Equity: 30.00%; International Equity: 10.00%; Fixed-Income: 40.00%; Short-Term Fixed-Income: 10.00%; and Inflation-Protected Assets: 10.00%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Growth & Income Fund, Large-Cap Growth Fund, Large-Cap Value Fund, Mid-Cap Growth Fund, Mid-Cap Value Fund, Small-Cap Equity Fund, Enhanced Large-Cap Growth Index Fund and Enhanced Large-Cap Value Index Fund (U.S. Equity); International Equity Fund, Enhanced International Equity Index Fund and Emerging Markets Equity Fund (International Equity); Bond Fund, Bond Plus Fund and High-Yield Fund (Fixed-Income); Short-Term Bond Fund and Money Market Fund (Short-Term Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change. Investors should note that the Fund has a significant level of equity exposure and this exposure could cause fluctuation in the value of the Fund depending on the performance of the equity markets generally.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund or the Underlying Funds typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Style Risk—The risk that use of a particular investing style (such as growth or value investing) may fall out of favor in the marketplace for various periods of time and result in underperformance relative to the broader market sector or significant declines in the value of an Underlying Funds’ portfolio securities.


· Risks of Growth Investing—The risks that growth stocks can perform differently from the market as a whole and other types of stocks. Growth stocks can also be more volatile, and experience sharper price fluctuations, than other stocks.


· Risks of Value Investing—The risks that value stocks can perform differently from the market as a whole and other types of stocks. Value stocks can also continue to be undervalued by the market for long periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Enhanced Index Risk—Certain Underlying Funds that are enhanced index funds may also underperform their benchmark indices due to differences between the investments of the Underlying Funds and their respective benchmark indices.


· Quantitative Analysis Risk—The risk that stocks selected by the Fund’s or an Underlying Fund’s investment adviser using quantitative modeling and analysis could perform differently from the market as a whole.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.


· Derivatives Risk—The risks associated with investing in derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments. An Underlying Fund may use futures and options, and an Underlying Fund may also use more complex derivatives such as swaps that might present liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested.

There can be no assurances that the Fund or an Underlying Fund's will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional, Retail and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

[1]The Retirement Class of the Fund has adopted a Distribution (12b-1) Plan that compensates the Fund's distributor, Teachers Personal Investors Services, Inc. ("TPIS"), for its expenses in providing distribution, promotional and/or shareholder services to Retirement Class shares at the annual rate of 0.05% of average daily net assets attributable to Retirement Class shares. In addition, TPIS has contractually agreed not to seek payment of this fee under the Plan for Retirement Class shares through September 30, 2012, unless changed with approval of the Board of Trustees.
[2]"Acquired Fund Fees and Expenses" are the Fund's proportionate amount of the expenses of any investment companies or pools in which it invests. These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly because they reduce Fund performance. Because "Acquired Fund Fees and Expenses" are included in the chart above, the Fund's operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund's May 31, 2011 annual report.
[3]Advisors has contractually agreed to waive the Fund's Management Fees equal to, on an annual basis, 0.10%. This waiver will remain in effect through September 30, 2012, unless changed with approval of the Board of Trustees.
[4]Under the Fund's expense reimbursement arrangements, the Fund's investment adviser, Teachers Advisors, Inc. ("Advisors"), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.25% of average daily net assets for Retirement Class shares; (ii) 0.15% of average daily net assets for Premier Class shares; and (iii) 0.00% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 24% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 8% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have recently retired or have an approximate target retirement year within a few years, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors who retired in 2010 or plan to retire within a few years of 2010.


The Fund expects to allocate approximately 49.00% of its assets to equity Underlying Funds and 51.00% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually become more conservative. The Fund had target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2010 and will reach the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2017 to 2020. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income, short-term fixed-income and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 36.00%; International Equity: 12.00%; Fixed-Income: 38.40%; Short-Term Fixed-Income: 6.80%; and Inflation-Protected Assets: 6.80%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Growth & Income Fund, Large-Cap Growth Fund, Large-Cap Value Fund, Mid-Cap Growth Fund, Mid-Cap Value Fund, Small-Cap Equity Fund, Enhanced Large-Cap Growth Index Fund and Enhanced Large-Cap Value Index Fund (U.S. Equity); International Equity Fund, Enhanced International Equity Index Fund and Emerging Markets Equity Fund (International Equity); Bond Fund, Bond Plus Fund and High-Yield Fund (Fixed-Income); Short-Term Bond Fund and Money Market Fund (Short-Term Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

The following chart shows how the investment glidepath for the Fund is expected to gradually move the Fund’s target allocations over time between the different target market sector allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks to achieve its final target market sector allocations approximately seven to ten years following the target date.

The Fund is designed to accommodate investors who invest in a fund up to their target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors should note that the Fund will continue to have a significant level of equity exposure up to, through and after its target retirement date, and this exposure could cause significant fluctuations in the value of the Fund depending on the performance of the equity markets generally.


Approximately seven to ten years after the Fund enters its target retirement year, the Board of Trustees may authorize the merger of the Fund into the Lifecycle Retirement Income Fund or other similar fund. Fund shareholders will receive prior notice of any such merger. The Lifecycle Retirement Income Fund is designed to maintain a relatively stable allocation among the Underlying Funds reflecting the resting point on the glidepath described in the chart above. More detailed information about the Lifecycle Retirement Income Fund is contained in the prospectus for that fund.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund or the Underlying Funds typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Style Risk—The risk that use of a particular investing style (such as growth or value investing) may fall out of favor in the marketplace for various periods of time and result in underperformance relative to the broader market sector or significant declines in the value of an Underlying Funds’ portfolio securities.


· Risks of Growth Investing—The risks that growth stocks can perform differently from the market as a whole and other types of stocks. Growth stocks can also be more volatile, and experience sharper price fluctuations, than other stocks.


· Risks of Value Investing—The risks that value stocks can perform differently from the market as a whole and other types of stocks. Value stocks can also continue to be undervalued by the market for long periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Enhanced Index Risk—Certain Underlying Funds that are enhanced index funds may also underperform their benchmark indices due to differences between the investments of the Underlying Funds and their respective benchmark indices.


· Quantitative Analysis Risk—The risk that stocks selected by the Fund’s or an Underlying Fund’s investment adviser using quantitative modeling and analysis could perform differently from the market as a whole.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.


· Derivatives Risk—The risks associated with investing in derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments. An Underlying Fund may use futures and options, and an Underlying Fund may also use more complex derivatives such as swaps that might present liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested.

There can be no assurances that the Fund or an Underlying Fund's will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

[1]The Retirement Class of the Fund has adopted a Distribution (12b-1) Plan that compensates the Fund's distributor, Teachers Personal Investors Services, Inc. ("TPIS"), for its expenses in providing distribution, promotional and/or shareholder services to Retirement Class shares at the annual rate of 0.05% of average daily net assets attributable to Retirement Class shares. In addition, TPIS has contractually agreed not to seek payment of this fee under the Plan for Retirement Class shares through September 30, 2012, unless changed with approval of the Board of Trustees.
[2]"Acquired Fund Fees and Expenses" are the Fund's proportionate amount of the expenses of any investment companies or pools in which it invests. These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly because they reduce Fund performance. Because "Acquired Fund Fees and Expenses" are included in the chart above, the Fund's operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund's May 31, 2011 annual report.
[3]Advisors has contractually agreed to waive the Fund's Management Fees equal to, on an annual basis, 0.10%. This waiver will remain in effect through September 30, 2012, unless changed with approval of the Board of Trustees.
[4]Under the Fund's expense reimbursement arrangements, the Fund's investment adviser, Teachers Advisors, Inc. ("Advisors"), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.25% of average daily net assets for Retirement Class shares; (ii) 0.15% of average daily net assets for Premier Class shares; and (iii) 0.00% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 19% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 5% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have an approximate target retirement year in mind, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2015.


The Fund expects to allocate approximately 56.40% of its assets to equity Underlying Funds and 43.60% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually become more conservative, moving to target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2015 and reaching the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2022 to 2025. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income, short-term fixed-income and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 41.10%; International Equity: 13.70%; Fixed-Income: 35.60%; Short-Term Fixed-Income: 4.80%; and Inflation-Protected Assets: 4.80%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Growth & Income Fund, Large-Cap Growth Fund, Large-Cap Value Fund, Mid-Cap Growth Fund, Mid-Cap Value Fund, Small-Cap Equity Fund, Enhanced Large-Cap Growth Index Fund and Enhanced Large-Cap Value Index Fund (U.S. Equity); International Equity Fund, Enhanced International Equity Index Fund and Emerging Markets Equity Fund (International Equity); Bond Fund, Bond Plus Fund and High-Yield Fund (Fixed-Income); Short-Term Bond Fund and Money Market Fund (Short-Term Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

The following chart shows how the investment glidepath for the Fund is expected to gradually move the Fund’s target allocations over time between the different target market sector allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks to achieve its final target market sector allocations approximately seven to ten years following the target date.

The Fund is designed to accommodate investors who invest in a fund up to their target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors should note that the Fund will continue to have a significant level of equity exposure up to, through and after its target retirement date, and this exposure could cause significant fluctuations in the value of the Fund depending on the performance of the equity markets generally.


Approximately seven to ten years after the Fund enters its target retirement year, the Board of Trustees may authorize the merger of the Fund into the Lifecycle Retirement Income Fund or other similar fund. Fund shareholders will receive prior notice of any such merger. The Lifecycle Retirement Income Fund is designed to maintain a relatively stable allocation among the Underlying Funds reflecting the resting point on the glidepath described in the chart above. More detailed information about the Lifecycle Retirement Income Fund is contained in the prospectus for that fund.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund or the Underlying Funds typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Style Risk—The risk that use of a particular investing style (such as growth or value investing) may fall out of favor in the marketplace for various periods of time and result in underperformance relative to the broader market sector or significant declines in the value of an Underlying Funds’ portfolio securities.


· Risks of Growth Investing—The risks that growth stocks can perform differently from the market as a whole and other types of stocks. Growth stocks can also be more volatile, and experience sharper price fluctuations, than other stocks.


· Risks of Value Investing—The risks that value stocks can perform differently from the market as a whole and other types of stocks. Value stocks can also continue to be undervalued by the market for long periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Enhanced Index Risk—Certain Underlying Funds that are enhanced index funds may also underperform their benchmark indices due to differences between the investments of the Underlying Funds and their respective benchmark indices.


· Quantitative Analysis Risk—The risk that stocks selected by the Fund’s or an Underlying Fund’s investment adviser using quantitative modeling and analysis could perform differently from the market as a whole.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.


· Derivatives Risk—The risks associated with investing in derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments. An Underlying Fund may use futures and options, and an Underlying Fund may also use more complex derivatives such as swaps that might present liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested.

There can be no assurances that the Fund or an Underlying Fund's will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower.

[1]The Retirement Class of the Fund has adopted a Distribution (12b-1) Plan that compensates the Fund's distributor, Teachers Personal Investors Services, Inc. ("TPIS"), for its expenses in providing distribution, promotional and/or shareholder services to Retirement Class shares at the annual rate of 0.05% of average daily net assets attributable to Retirement Class shares. In addition, TPIS has contractually agreed not to seek payment of this fee under the Plan for Retirement Class shares through September 30, 2012, unless changed with approval of the Board of Trustees.
[2]"Acquired Fund Fees and Expenses" are the Fund's proportionate amount of the expenses of any investment companies or pools in which it invests. These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly because they reduce Fund performance. Because "Acquired Fund Fees and Expenses" are included in the chart above, the Fund's operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund's May 31, 2011 annual report.
[3]Advisors has contractually agreed to waive the Fund's Management Fees equal to, on an annual basis, 0.10%. This waiver will remain in effect through September 30, 2012, unless changed with approval of the Board of Trustees.
[4]Under the Fund's expense reimbursement arrangements, the Fund's investment adviser, Teachers Advisors, Inc. ("Advisors"), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.25% of average daily net assets for Retirement Class shares; (ii) 0.15% of average daily net assets for Premier Class shares; and (iii) 0.00% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 16% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 4% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have an approximate target retirement year in mind, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2020.


The Fund expects to allocate approximately 64.40% of its assets to equity Underlying Funds and 35.60% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually become more conservative, moving to target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2020 and reaching the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2027 to 2030. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income, short-term fixed-income and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 47.10%; International Equity: 15.70%; Fixed-Income: 31.60%; Short-Term Fixed-Income: 2.80%; and Inflation-Protected Assets: 2.80%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Growth & Income Fund, Large-Cap Growth Fund, Large-Cap Value Fund, Mid-Cap Growth Fund, Mid-Cap Value Fund, Small-Cap Equity Fund, Enhanced Large-Cap Growth Index Fund and Enhanced Large-Cap Value Index Fund (U.S. Equity); International Equity Fund, Enhanced International Equity Index Fund and Emerging Markets Equity Fund (International Equity); Bond Fund, Bond Plus Fund and High-Yield Fund (Fixed-Income); Short-Term Bond Fund and Money Market Fund (Short-Term Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

The following chart shows how the investment glidepath for the Fund is expected to gradually move the Fund’s target allocations over time between the different target market sector allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks to achieve its final target market sector allocations approximately seven to ten years following the target date.

The Fund is designed to accommodate investors who invest in a fund up to their target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors should note that the Fund will continue to have a significant level of equity exposure up to, through and after its target retirement date, and this exposure could cause significant fluctuations in the value of the Fund depending on the performance of the equity markets generally.


Approximately seven to ten years after the Fund enters its target retirement year, the Board of Trustees may authorize the merger of the Fund into the Lifecycle Retirement Income Fund or other similar fund. Fund shareholders will receive prior notice of any such merger. The Lifecycle Retirement Income Fund is designed to maintain a relatively stable allocation among the Underlying Funds reflecting the resting point on the glidepath described in the chart above. More detailed information about the Lifecycle Retirement Income Fund is contained in the prospectus for that fund.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund or the Underlying Funds typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Style Risk—The risk that use of a particular investing style (such as growth or value investing) may fall out of favor in the marketplace for various periods of time and result in underperformance relative to the broader market sector or significant declines in the value of an Underlying Funds’ portfolio securities.


· Risks of Growth Investing—The risks that growth stocks can perform differently from the market as a whole and other types of stocks. Growth stocks can also be more volatile, and experience sharper price fluctuations, than other stocks.


· Risks of Value Investing—The risks that value stocks can perform differently from the market as a whole and other types of stocks. Value stocks can also continue to be undervalued by the market for long periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Enhanced Index Risk—Certain Underlying Funds that are enhanced index funds may also underperform their benchmark indices due to differences between the investments of the Underlying Funds and their respective benchmark indices.


· Quantitative Analysis Risk—The risk that stocks selected by the Fund’s or an Underlying Fund’s investment adviser using quantitative modeling and analysis could perform differently from the market as a whole.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.


· Derivatives Risk—The risks associated with investing in derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments. An Underlying Fund may use futures and options, and an Underlying Fund may also use more complex derivatives such as swaps that might present liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested.

There can be no assurances that the Fund or an Underlying Fund's will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

Because "Acquired Fund Fees and Expenses" are included in the chart above, the Fund's operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund's May 31, 2011 annual report.
[3]Advisors has contractually agreed to waive the Fund's Management Fees equal to, on an annual basis, 0.10%. This waiver will remain in effect through September 30, 2012, unless changed with approval of the Board of Trustees.
[4]Under the Fund's expense reimbursement arrangements, the Fund's investment adviser, Teachers Advisors, Inc. ("Advisors"), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.25% of average daily net assets for Retirement Class shares; (ii) 0.15% of average daily net assets for Premier Class shares; and (iii) 0.00% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 15% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 4% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have an approximate target retirement year in mind, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2025.


The Fund expects to allocate approximately 72.40% of its assets to equity Underlying Funds and 27.60% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually become more conservative, moving to target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2025 and reaching the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2032 to 2035. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income, short-term fixed-income and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 53.10%; International Equity: 17.70%; Fixed-Income: 27.60%; Short-Term Fixed-Income: 0.80%; and Inflation-Protected Assets: 0.80%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Growth & Income Fund, Large-Cap Growth Fund, Large-Cap Value Fund, Mid-Cap Growth Fund, Mid-Cap Value Fund, Small-Cap Equity Fund, Enhanced Large-Cap Growth Index Fund and Enhanced Large-Cap Value Index Fund (U.S. Equity); International Equity Fund, Enhanced International Equity Index Fund and Emerging Markets Equity Fund (International Equity); Bond Fund, Bond Plus Fund and High-Yield Fund (Fixed-Income); Short-Term Bond Fund and Money Market Fund (Short-Term Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

The Fund is designed to accommodate investors who invest in a fund up to their target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors should note that the Fund will continue to have a significant level of equity exposure up to, through and after its target retirement date, and this exposure could cause significant fluctuations in the value of the Fund depending on the performance of the equity markets generally.


Approximately seven to ten years after the Fund enters its target retirement year, the Board of Trustees may authorize the merger of the Fund into the Lifecycle Retirement Income Fund or other similar fund. Fund shareholders will receive prior notice of any such merger. The Lifecycle Retirement Income Fund is designed to maintain a relatively stable allocation among the Underlying Funds reflecting the resting point on the glidepath described in the chart above. More detailed information about the Lifecycle Retirement Income Fund is contained in the prospectus for that fund.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund or the Underlying Funds typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Style Risk—The risk that use of a particular investing style (such as growth or value investing) may fall out of favor in the marketplace for various periods of time and result in underperformance relative to the broader market sector or significant declines in the value of an Underlying Funds’ portfolio securities.


· Risks of Growth Investing—The risks that growth stocks can perform differently from the market as a whole and other types of stocks. Growth stocks can also be more volatile, and experience sharper price fluctuations, than other stocks.


· Risks of Value Investing—The risks that value stocks can perform differently from the market as a whole and other types of stocks. Value stocks can also continue to be undervalued by the market for long periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Enhanced Index Risk—Certain Underlying Funds that are enhanced index funds may also underperform their benchmark indices due to differences between the investments of the Underlying Funds and their respective benchmark indices.


· Quantitative Analysis Risk—The risk that stocks selected by the Fund’s or an Underlying Fund’s investment adviser using quantitative modeling and analysis could perform differently from the market as a whole.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.


· Derivatives Risk—The risks associated with investing in derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments. An Underlying Fund may use futures and options, and an Underlying Fund may also use more complex derivatives such as swaps that might present liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested.

There can be no assurances that the Fund or an Underlying Fund's will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

In addition, TPIS has contractually agreed not to seek payment of this fee under the Plan for Retirement Class shares through September 30, 2012, unless changed with approval of the Board of Trustees.
[2]"Acquired Fund Fees and Expenses" are the Fund's proportionate amount of the expenses of any investment companies or pools in which it invests. These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly because they reduce Fund performance.

These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 14% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 4% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have an approximate target retirement year in mind, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2030.


The Fund expects to allocate approximately 80.40% of its assets to equity Underlying Funds and 19.60% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually become more conservative, moving to target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2030 and reaching the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2037 to 2040. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income, short-term fixed-income and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 59.10%; International Equity: 19.70%; Fixed-Income: 21.20%; Short-Term Fixed-Income: 0.00%; and Inflation-Protected Assets: 0.00%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Growth & Income Fund, Large-Cap Growth Fund, Large-Cap Value Fund, Mid-Cap Growth Fund, Mid-Cap Value Fund, Small-Cap Equity Fund, Enhanced Large-Cap Growth Index Fund and Enhanced Large-Cap Value Index Fund (U.S. Equity); International Equity Fund, Enhanced International Equity Index Fund and Emerging Markets Equity Fund (International Equity); Bond Fund, Bond Plus Fund and High-Yield Fund (Fixed Income); Short-Term Bond Fund and Money Market Fund (Short-Term Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective.

The Fund is designed to accommodate investors who invest in a fund up to their target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors should note that the Fund will continue to have a significant level of equity exposure up to, through and after its target retirement date, and this exposure could cause significant fluctuations in the value of the Fund depending on the performance of the equity markets generally.


Approximately seven to ten years after the Fund enters its target retirement year, the Board of Trustees may authorize the merger of the Fund into the Lifecycle Retirement Income Fund or other similar fund. Fund shareholders will receive prior notice of any such merger. The Lifecycle Retirement Income Fund is designed to maintain a relatively stable allocation among the Underlying Funds reflecting the resting point on the glidepath described in the chart above. More detailed information about the Lifecycle Retirement Income Fund is contained in the prospectus for that fund.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund or the Underlying Funds typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Style Risk—The risk that use of a particular investing style (such as growth or value investing) may fall out of favor in the marketplace for various periods of time and result in underperformance relative to the broader market sector or significant declines in the value of an Underlying Funds’ portfolio securities.


· Risks of Growth Investing—The risks that growth stocks can perform differently from the market as a whole and other types of stocks. Growth stocks can also be more volatile, and experience sharper price fluctuations, than other stocks.


· Risks of Value Investing—The risks that value stocks can perform differently from the market as a whole and other types of stocks. Value stocks can also continue to be undervalued by the market for long periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Enhanced Index Risk—Certain Underlying Funds that are enhanced index funds may also underperform their benchmark indices due to differences between the investments of the Underlying Funds and their respective benchmark indices.


· Quantitative Analysis Risk—The risk that stocks selected by the Fund’s or an Underlying Fund’s investment adviser using quantitative modeling and analysis could perform differently from the market as a whole.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.


· Derivatives Risk—The risks associated with investing in derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments. An Underlying Fund may use futures and options, and an Underlying Fund may also use more complex derivatives such as swaps that might present liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested.

There can be no assurances that the Fund or an Underlying Fund's will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

[1]The Retirement Class of the Fund has adopted a Distribution (12b-1) Plan that compensates the Fund's distributor, Teachers Personal Investors Services, Inc. ("TPIS"), for its expenses in providing distribution, promotional and/or shareholder services to Retirement Class shares at the annual rate of 0.05% of average daily net assets attributable to Retirement Class shares. In addition, TPIS has contractually agreed not to seek payment of this fee under the Plan for Retirement Class shares through September 30, 2012, unless changed with approval of the Board of Trustees.
[2]"Acquired Fund Fees and Expenses" are the Fund's proportionate amount of the expenses of any investment companies or pools in which it invests. These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly because they reduce Fund performance. Because "Acquired Fund Fees and Expenses" are included in the chart above, the Fund's operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund's May 31, 2011 annual report.
[3]Advisors has contractually agreed to waive the Fund's Management Fees equal to, on an annual basis, 0.10%. This waiver will remain in effect through September 30, 2012, unless changed with approval of the Board of Trustees.
[4]Under the Fund's expense reimbursement arrangements, the Fund's investment adviser, Teachers Advisors, Inc. ("Advisors"), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.25% of average daily net assets for Retirement Class shares; (ii) 0.15% of average daily net assets for Premier Class shares; and (iii) 0.00% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 11% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 7% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have an approximate target retirement year in mind, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2035.


The Fund expects to allocate approximately 88.40% of its assets to equity Underlying Funds and 11.60% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually becomes more conservative, moving to target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2035 and reaching the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2042 to 2045. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income, short-term fixed-income and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 65.10%; International Equity: 21.70%; Fixed-Income: 13.20%; Short-Term Fixed-Income: 0.00%; and Inflation-Protected Assets: 0.00%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Growth & Income Fund, Large-Cap Growth Fund, Large-Cap Value Fund, Mid-Cap Growth Fund, Mid-Cap Value Fund, Small-Cap Equity Fund, Enhanced Large-Cap Growth Index Fund and Enhanced Large-Cap Value Index Fund (U.S. Equity); International Equity Fund, Enhanced International Equity Index Fund and Emerging Markets Equity Fund (International Equity); Bond Fund, Bond Plus Fund and High-Yield Fund (Fixed-Income); Short-Term Bond Fund and Money Market Fund (Short-Term Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund or the Underlying Funds typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Style Risk—The risk that use of a particular investing style (such as growth or value investing) may fall out of favor in the marketplace for various periods of time and result in underperformance relative to the broader market sector or significant declines in the value of an Underlying Funds’ portfolio securities.


· Risks of Growth Investing—The risks that growth stocks can perform differently from the market as a whole and other types of stocks. Growth stocks can also be more volatile, and experience sharper price fluctuations, than other stocks.


· Risks of Value Investing—The risks that value stocks can perform differently from the market as a whole and other types of stocks. Value stocks can also continue to be undervalued by the market for long periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Enhanced Index Risk—Certain Underlying Funds that are enhanced index funds may also underperform their benchmark indices due to differences between the investments of the Underlying Funds and their respective benchmark indices.


· Quantitative Analysis Risk—The risk that stocks selected by the Fund’s or an Underlying Fund’s investment adviser using quantitative modeling and analysis could perform differently from the market as a whole.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.


· Derivatives Risk—The risks associated with investing in derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments. An Underlying Fund may use futures and options, and an Underlying Fund may also use more complex derivatives such as swaps that might present liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested.

There can be no assurances that the Fund or an Underlying Fund's will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

[1]The Retirement Class of the Fund has adopted a Distribution (12b-1) Plan that compensates the Fund's distributor, Teachers Personal Investors Services, Inc. ("TPIS"), for its expenses in providing distribution, promotional and/or shareholder services to Retirement Class shares at the annual rate of 0.05% of average daily net assets attributable to Retirement Class shares. In addition, TPIS has contractually agreed not to seek payment of this fee under the Plan for Retirement Class shares through September 30, 2012, unless changed with approval of the Board of Trustees.
[2]"Acquired Fund Fees and Expenses" are the Fund's proportionate amount of the expenses of any investment companies or pools in which it invests. These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly because they reduce Fund performance. Because "Acquired Fund Fees and Expenses" are included in the chart above, the Fund's operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund's May 31, 2011 annual report.
[3]Advisors has contractually agreed to waive the Fund's Management Fees equal to, on an annual basis, 0.10%. This waiver will remain in effect through September 30, 2012, unless changed with approval of the Board of Trustees.
[4]Under the Fund's expense reimbursement arrangements, the Fund's investment adviser, Teachers Advisors, Inc. ("Advisors"), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.25% of average daily net assets for Retirement Class shares; (ii) 0.15% of average daily net assets for Premier Class shares; and (iii) 0.00% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 10% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 8% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have an approximate target retirement year in mind, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2040.


The Fund expects to allocate approximately 90.00% of its assets to equity Underlying Funds and 10.00% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually become more conservative, moving to target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2040 and reaching the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2047 to 2050. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income, short-term fixed-income and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 67.50%; International Equity: 22.50%; Fixed-Income: 10.00%; Short-Term Fixed-Income: 0.00%; and Inflation-Protected Assets: 0.00%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Growth & Income Fund, Large-Cap Growth Fund, Large-Cap Value Fund, Mid-Cap Growth Fund, Mid-Cap Value Fund, Small-Cap Equity Fund, Enhanced Large-Cap Growth Index Fund and Enhanced Large-Cap Value Index Fund (U.S. Equity); International Equity Fund, Enhanced International Equity Index Fund and Emerging Markets Equity Fund (International Equity); Bond Fund, Bond Plus Fund and High-Yield Fund (Fixed-Income); Short-Term Bond Fund and Money Market Fund (Short-Term Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

The following chart shows how the investment glidepath for the Fund is expected to gradually move the Fund’s target allocations over time between the different target market sector allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks to achieve its final target market sector allocations approximately seven to ten years following the target date.

The Fund is designed to accommodate investors who invest in a fund up to their target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors should note that the Fund will continue to have a significant level of equity exposure up to, through and after its target retirement date, and this exposure could cause significant fluctuations in the value of the Fund depending on the performance of the equity markets generally.


Approximately seven to ten years after the Fund enters its target retirement year, the Board of Trustees may authorize the merger of the Fund into the Lifecycle Retirement Income Fund or other similar fund. Fund shareholders will receive prior notice of any such merger. The Lifecycle Retirement Income Fund is designed to maintain a relatively stable allocation among the Underlying Funds reflecting the resting point on the glidepath described in the chart above. More detailed information about the Lifecycle Retirement Income Fund is contained in the prospectus for that fund.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund or the Underlying Funds typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Style Risk—The risk that use of a particular investing style (such as growth or value investing) may fall out of favor in the marketplace for various periods of time and result in underperformance relative to the broader market sector or significant declines in the value of an Underlying Funds’ portfolio securities.


· Risks of Growth Investing—The risks that growth stocks can perform differently from the market as a whole and other types of stocks. Growth stocks can also be more volatile, and experience sharper price fluctuations, than other stocks.


· Risks of Value Investing—The risks that value stocks can perform differently from the market as a whole and other types of stocks. Value stocks can also continue to be undervalued by the market for long periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Enhanced Index Risk—Certain Underlying Funds that are enhanced index funds may also underperform their benchmark indices due to differences between the investments of the Underlying Funds and their respective benchmark indices.


· Quantitative Analysis Risk—The risk that stocks selected by the Fund’s or an Underlying Fund’s investment adviser using quantitative modeling and analysis could perform differently from the market as a whole.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.


· Derivatives Risk—The risks associated with investing in derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments. An Underlying Fund may use futures and options, and an Underlying Fund may also use more complex derivatives such as swaps that might present liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested.

There can be no assurances that the Fund or an Underlying Fund's will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

[1]The Retirement Class of the Fund has adopted a Distribution (12b-1) Plan that compensates the Fund's distributor, Teachers Personal Investors Services, Inc. ("TPIS"), for its expenses in providing distribution, promotional and/or shareholder services to Retirement Class shares at the annual rate of 0.05% of average daily net assets attributable to Retirement Class shares. In addition, TPIS has contractually agreed not to seek payment of this fee under the Plan for Retirement Class shares through September 30, 2012, unless changed with approval of the Board of Trustees.
[2]"Acquired Fund Fees and Expenses" are the Fund's proportionate amount of the expenses of any investment companies or pools in which it invests. These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly because they reduce Fund performance. Because "Acquired Fund Fees and Expenses" are included in the chart above, the Fund's operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund's May 31, 2011 annual report.
[3]Advisors has contractually agreed to waive the Fund's Management Fees equal to, on an annual basis, 0.10%. This waiver will remain in effect through September 30, 2012, unless changed with approval of the Board of Trustees.
[4]Under the Fund's expense reimbursement arrangements, the Fund's investment adviser, Teachers Advisors, Inc. ("Advisors"), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.25% of average daily net assets for Retirement Class shares; (ii) 0.15% of average daily net assets for Premier Class shares; and (iii) 0.00% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 18% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 8% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have an approximate target retirement year in mind, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2045.


The Fund expects to allocate approximately 90.00% of its assets to equity Underlying Funds and 10.00% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually become more conservative, moving to target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2045 and reaching the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2052 to 2055. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income, short-term fixed-income and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 67.50%; International Equity: 22.50%; Fixed-Income: 10.00%; Short-Term Fixed-Income: 0.00%; and Inflation-Protected Assets: 0.00%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Growth & Income Fund, Large-Cap Growth Fund, Large-Cap Value Fund, Mid-Cap Growth Fund, Mid-Cap Value Fund, Small-Cap Equity Fund, Enhanced Large-Cap Growth Index Fund and Enhanced Large-Cap Value Index Fund (U.S. Equity); International Equity Fund, Enhanced International Equity Index Fund and Emerging Markets Equity Fund (International Equity); Bond Fund, Bond Plus Fund and High-Yield Fund (Fixed-Income); Short-Term Bond Fund and Money Market Fund (Short-Term Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

The following chart shows how the investment glidepath for the Fund is expected to gradually move the Fund’s target allocations over time between the different target market sector allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks to achieve its final target market sector allocations approximately seven to ten years following the target date.

The Fund is designed to accommodate investors who invest in a fund up to their target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors should note that the Fund will continue to have a significant level of equity exposure up to, through and after its target retirement date, and this exposure could cause significant fluctuations in the value of the Fund depending on the performance of the equity markets generally.


Approximately seven to ten years after the Fund enters its target retirement year, the Board of Trustees may authorize the merger of the Fund into the Lifecycle Retirement Income Fund or other similar fund. Fund shareholders will receive prior notice of any such merger. The Lifecycle Retirement Income Fund is designed to maintain a relatively stable allocation among the Underlying Funds reflecting the resting point on the glidepath described in the chart above. More detailed information about the Lifecycle Retirement Income Fund is contained in the prospectus for that fund.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund or the Underlying Funds typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Style Risk—The risk that use of a particular investing style (such as growth or value investing) may fall out of favor in the marketplace for various periods of time and result in underperformance relative to the broader market sector or significant declines in the value of an Underlying Funds’ portfolio securities.


· Risks of Growth Investing—The risks that growth stocks can perform differently from the market as a whole and other types of stocks. Growth stocks can also be more volatile, and experience sharper price fluctuations, than other stocks.


· Risks of Value Investing—The risks that value stocks can perform differently from the market as a whole and other types of stocks. Value stocks can also continue to be undervalued by the market for long periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Enhanced Index Risk—Certain Underlying Funds that are enhanced index funds may also underperform their benchmark indices due to differences between the investments of the Underlying Funds and their respective benchmark indices.


· Quantitative Analysis Risk—The risk that stocks selected by the Fund’s or an Underlying Fund’s investment adviser using quantitative modeling and analysis could perform differently from the market as a whole.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.


· Derivatives Risk—The risks associated with investing in derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments. An Underlying Fund may use futures and options, and an Underlying Fund may also use more complex derivatives such as swaps that might present liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested.

There can be no assurances that the Fund or an Underlying Fund's will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

Because "Acquired Fund Fees and Expenses" are included in the chart above, the Fund's operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund's May 31, 2011 annual report.

[4]Under the Fund's expense reimbursement arrangements, the Fund's investment adviser, Teachers Advisors, Inc. ("Advisors"), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.25% of average daily net assets for Retirement Class shares; (ii) 0.15% of average daily net assets for Premier Class shares; and (iii) 0.00% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 24% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 8% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have an approximate target retirement year in mind, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2050.


The Fund expects to allocate approximately 90.00% of its assets to equity Underlying Funds and 10.00% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually become more conservative, moving to target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2050 and reaching the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2057 to 2060. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income, short-term fixed-income and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 67.50%; International Equity: 22.50%; Fixed-Income: 10.00%; Short-Term Fixed-Income: 0.00%; and Inflation-Protected Assets: 0.00%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Growth & Income Fund, Large-Cap Growth Fund, Large-Cap Value Fund, Mid-Cap Growth Fund, Mid-Cap Value Fund, Small-Cap Equity Fund, Enhanced Large-Cap Growth Index Fund and Enhanced Large-Cap Value Index Fund (U.S. Equity); International Equity Fund, Enhanced International Equity Index Fund and Emerging Markets Equity Fund (International Equity); Bond Fund, Bond Plus Fund and High-Yield Fund (Fixed-Income); Short-Term Bond Fund and Money Market Fund (Short-Term Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

The following chart shows how the investment glidepath for the Fund is expected to gradually move the Fund’s target allocations over time between the different target market sector allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks to achieve its final target market sector allocations approximately seven to ten years following the target date.

The Fund is designed to accommodate investors who invest in a fund up to their target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors should note that the Fund will continue to have a significant level of equity exposure up to, through and after its target retirement date, and this exposure could cause significant fluctuations in the value of the Fund depending on the performance of the equity markets generally.


Approximately seven to ten years after the Fund enters its target retirement year, the Board of Trustees may authorize the merger of the Fund into the Lifecycle Retirement Income Fund or other similar fund. Fund shareholders will receive prior notice of any such merger. The Lifecycle Retirement Income Fund is designed to maintain a relatively stable allocation among the Underlying Funds reflecting the resting point on the glidepath described in the chart above. More detailed information about the Lifecycle Retirement Income Fund is contained in the prospectus for that fund.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund or the Underlying Funds typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Style Risk—The risk that use of a particular investing style (such as growth or value investing) may fall out of favor in the marketplace for various periods of time and result in underperformance relative to the broader market sector or significant declines in the value of an Underlying Funds’ portfolio securities.


· Risks of Growth Investing—The risks that growth stocks can perform differently from the market as a whole and other types of stocks. Growth stocks can also be more volatile, and experience sharper price fluctuations, than other stocks.


· Risks of Value Investing—The risks that value stocks can perform differently from the market as a whole and other types of stocks. Value stocks can also continue to be undervalued by the market for long periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Enhanced Index Risk—Certain Underlying Funds that are enhanced index funds may also underperform their benchmark indices due to differences between the investments of the Underlying Funds and their respective benchmark indices.


· Quantitative Analysis Risk—The risk that stocks selected by the Fund’s or an Underlying Fund’s investment adviser using quantitative modeling and analysis could perform differently from the market as a whole.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.


· Derivatives Risk—The risks associated with investing in derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments. An Underlying Fund may use futures and options, and an Underlying Fund may also use more complex derivatives such as swaps that might present liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested.

There can be no assurances that the Fund or an Underlying Fund's will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the one-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 1% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have an approximate target retirement year in mind, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2055.


The Fund expects to allocate approximately 90.00% of its assets to equity Underlying Funds and 10.00% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually become more conservative, moving to target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2055 and reaching the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2062 to 2065. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income, short-term fixed-income and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 67.50%; International Equity: 22.50%; Fixed-Income: 10.00%; Short-Term Fixed-Income: 0.00%; and Inflation-Protected Assets: 0.00%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Growth & Income Fund, Large-Cap Growth Fund, Large-Cap Value Fund, Mid-Cap Growth Fund, Mid-Cap Value Fund, Small-Cap Equity Fund, Enhanced Large-Cap Growth Index Fund and Enhanced Large-Cap Value Index Fund (U.S. Equity); International Equity Fund, Enhanced International Equity Index Fund and Emerging Markets Equity Fund (International Equity); Bond Fund, Bond Plus Fund and High-Yield Fund (Fixed-Income); Short-Term Bond Fund and Money Market Fund (Short-Term Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

The Fund is designed to accommodate investors who invest in a fund up to their target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors should note that the Fund will continue to have a significant level of equity exposure up to, through and after its target retirement date, and this exposure could cause significant fluctuations in the value of the Fund depending on the performance of the equity markets generally.


Approximately seven to ten years after the Fund enters its target retirement year, the Board of Trustees may authorize the merger of the Fund into the Lifecycle Retirement Income Fund or other similar fund. Fund shareholders will receive prior notice of any such merger. The Lifecycle Retirement Income Fund is designed to maintain a relatively stable allocation among the Underlying Funds reflecting the resting point on the glidepath described in the chart above. More detailed information about the Lifecycle Retirement Income Fund is contained in the prospectus for that fund.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund or the Underlying Funds typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Style Risk—The risk that use of a particular investing style (such as growth or value investing) may fall out of favor in the marketplace for various periods of time and result in underperformance relative to the broader market sector or significant declines in the value of an Underlying Funds’ portfolio securities.


· Risks of Growth Investing—The risks that growth stocks can perform differently from the market as a whole and other types of stocks. Growth stocks can also be more volatile, and experience sharper price fluctuations, than other stocks.


· Risks of Value Investing—The risks that value stocks can perform differently from the market as a whole and other types of stocks. Value stocks can also continue to be undervalued by the market for long periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Enhanced Index Risk—Certain Underlying Funds that are enhanced index funds may also underperform their benchmark indices due to differences between the investments of the Underlying Funds and their respective benchmark indices.


· Quantitative Analysis Risk—The risk that stocks selected by the Fund’s or an Underlying Fund’s investment adviser using quantitative modeling and analysis could perform differently from the market as a whole.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.


· Derivatives Risk—The risks associated with investing in derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments. An Underlying Fund may use futures and options, and an Underlying Fund may also use more complex derivatives such as swaps that might present liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested.

There can be no assurances that the Fund or an Underlying Fund's will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

[1]The Retirement Class of the Fund has adopted a Distribution (12b-1) Plan that compensates the Fund's distributor, Teachers Personal Investors Services, Inc. ("TPIS"), for its expenses in providing distribution, promotional and/or shareholder services to Retirement Class shares at the annual rate of 0.05% of average daily net assets attributable to Retirement Class shares. In addition, TPIS has contractually agreed not to seek payment of this fee under the Plan for Retirement Class shares through September 30, 2012, unless changed with approval of the Board of Trustees.
[2]"Acquired Fund Fees and Expenses" are the Fund's proportionate amount of the expenses of any investment companies or pools in which it invests. These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly because they reduce Fund performance. Because "Acquired Fund Fees and Expenses" are included in the chart above, the Fund's operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund's May 31, 2011 annual report.
[3]In addition to the expense reimbursement arrangements, Advisors has contractually agreed to waive a portion of the Fund's Management Fees equal to, on an annual basis, 0.04%. This waiver will remain in effect through September 30, 2012, unless changed with approval of the Board of Trustees.
[4]Under the Fund's expense reimbursement arrangements, the Fund's investment adviser, Teachers Advisors, Inc. ("Advisors"), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.35% of average daily net assets for Retirement Class shares; (ii) 0.25% of average daily net assets for Premier Class shares; and (iii) 0.10% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 39% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 13% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). The Fund invests in Underlying Funds according to a relatively stable asset allocation strategy that will not gradually adjust over time and is designed for investors who are already in or entering retirement (i.e., have already passed their retirement year). The Fund has a policy of investing at least 80% of its assets in Underlying Funds that are managed to seek investment returns that track particular market indices. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.


The Fund expects to allocate approximately 40.00% of its assets to equity Underlying Funds and 60.00% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations may be changed and actual allocations may vary up to 10% from the targets. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income, and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which may change, are approximately as follows: U.S. Equity: 30.00%; International Equity: 10.00%; Fixed-Income: 50.00%; and Inflation-Protected Assets: 10.00%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Equity Index Fund (U.S. Equity); International Equity Index Fund and Emerging Markets Equity Index Fund (International Equity); Bond Index Fund (Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change. Investors should note that the Fund has a significant level of equity exposure and this exposure could cause fluctuation in the value of the Fund depending on the performance of the equity markets generally.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, or the Underlying Funds, typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Index Risk—The risk that an Underlying Fund’s performance will not correspond to its benchmark index for any period of time and may underperform such index or the overall stock market. Additionally, to the extent that an Underlying Fund’s investments vary from the composition of its benchmark index, an Underlying Fund’s performance could potentially vary from the index’s performance to a greater extent than if an Underlying Fund merely attempted to replicate the index.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries.


Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

[1]The Retirement Class of the Fund has adopted a Distribution (12b-1) Plan that compensates the Fund's distributor, Teachers Personal Investors Services, Inc. ("TPIS"), for its expenses in providing distribution, promotional and/or shareholder services to Retirement Class shares at the annual rate of 0.05% of average daily net assets attributable to Retirement Class shares. In addition, TPIS has contractually agreed not to seek payment of this fee under the Plan for Retirement Class shares through September 30, 2012, unless changed with approval of the Board of Trustees.
[2]"Acquired Fund Fees and Expenses" are the Fund's proportionate amount of the expenses of any investment companies or pools in which it invests. These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly because they reduce Fund performance. Because "Acquired Fund Fees and Expenses" are included in the chart above, the Fund's operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund's May 31, 2011 annual report.
[3]In addition to the expense reimbursement arrangements, Advisors has contractually agreed to waive a portion of the Fund's Management Fees equal to, on an annual basis, 0.03%. This waiver will remain in effect through September 30, 2012, unless changed with approval of the Board of Trustees.
[4]Under the Fund's expense reimbursement arrangements, the Fund's investment adviser, Teachers Advisors, Inc. ("Advisors"), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.35% of average daily net assets for Retirement Class shares; (ii) 0.25% of average daily net assets for Premier Class shares; and (iii) 0.10% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 43% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 38% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have recently retired or have an approximate target retirement year within a few years, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2010. The Fund has a policy of investing at least 80% of its assets (net assets, plus the amount of any borrowings for investment purposes) in Underlying Funds that are managed to seek investment returns that track particular market indices.


The Fund expects to allocate approximately 49.00% of its assets to equity Underlying Funds and 51.00% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, will gradually become more conservative. The Fund had target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2010 and will reach the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2017 to 2020. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 36.00%; International Equity: 12.00%; Fixed-Income: 45.20%; and Inflation-Protected Assets: 6.80%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Equity Index Fund (U.S. Equity); International Equity Index Fund and Emerging Markets Equity Index Fund (International Equity); Bond Index Fund (Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

The following chart shows how the investment glidepath for the Fund is expected to gradually move the Fund’s target allocations over time between the different target market sector allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks to achieve its final target market sector allocations approximately seven to ten years following the target date.

The Fund is designed to accommodate investors who invest in a fund up to their target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors should note that the Fund will continue to have a significant level of equity exposure up to, through and after its target retirement date, and this exposure could cause significant fluctuations in the value of the Fund depending on the performance of the equity markets generally.


Approximately seven to ten years after the Fund enters its target retirement year, the Board of Trustees may authorize the merger of the Fund into the Lifecycle Index Retirement Income Fund or other similar fund. Fund shareholders will receive prior notice of any such merger. The Lifecycle Index Retirement Income Fund is designed to maintain a relatively stable allocation among the Underlying Funds reflecting the resting point on the glidepath described in the chart above. More detailed information about the Lifecycle Index Retirement Income Fund is contained in the prospectus for that fund.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, or the Underlying Funds, typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Index Risk—The risk that an Underlying Fund’s performance will not correspond to its benchmark index for any period of time and may underperform such index or the overall stock market. Additionally, to the extent that an Underlying Fund’s investments vary from the composition of its benchmark index, an Underlying Fund’s performance could potentially vary from the index’s performance to a greater extent than if an Underlying Fund merely attempted to replicate the index.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.

There can be no assurances that the Fund or an Underlying Fund will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly because they reduce Fund performance. Because "Acquired Fund Fees and Expenses" are included in the chart above, the Fund's operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund's May 31, 2011 annual report.
[3]In addition to the expense reimbursement arrangements, Advisors has contractually agreed to waive a portion of the Fund's Management Fees equal to, on an annual basis, 0.02%. This waiver will remain in effect through September 30, 2012, unless changed with approval of the Board of Trustees.

These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 23% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 13% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have an approximate target retirement year in mind, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2015. The Fund has a policy of investing at least 80% of its assets (net assets, plus the amount of any borrowings for investment purposes) in Underlying Funds that are managed to seek investment returns that track particular market indices.


The Fund expects to allocate approximately 56.40% of its assets to equity Underlying Funds and 43.60% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, gradually become more conservative, moving to target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2015 and reaching the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2022 to 2025. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 41.10%; International Equity: 13.70%; Fixed-Income: 40.40%; and Inflation-Protected Assets: 4.80%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Equity Index Fund (U.S. Equity); International Equity Index Fund and Emerging Markets Equity Index Fund (International Equity); Bond Index Fund (Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

The Fund is designed to accommodate investors who invest in a fund up to their target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors should note that the Fund will continue to have a significant level of equity exposure up to, through and after its target retirement date, and this exposure could cause significant fluctuations in the value of the Fund depending on the performance of the equity markets generally.


Approximately seven to ten years after the Fund enters its target retirement year, the Board of Trustees may authorize the merger of the Fund into the Lifecycle Index Retirement Income Fund or other similar fund. Fund shareholders will receive prior notice of any such merger. The Lifecycle Index Retirement Income Fund is designed to maintain a relatively stable allocation among the Underlying Funds reflecting the resting point on the glidepath described in the chart above. More detailed information about the Lifecycle Index Retirement Income Fund is contained in the prospectus for that fund.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, or the Underlying Funds, typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Index Risk—The risk that an Underlying Fund’s performance will not correspond to its benchmark index for any period of time and may underperform such index or the overall stock market. Additionally, to the extent that an Underlying Fund’s investments vary from the composition of its benchmark index, an Underlying Fund’s performance could potentially vary from the index’s performance to a greater extent than if an Underlying Fund merely attempted to replicate the index.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.

There can be no assurances that the Fund or an Underlying Fund will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

[1]The Retirement Class of the Fund has adopted a Distribution (12b-1) Plan that compensates the Fund's distributor, Teachers Personal Investors Services, Inc. ("TPIS"), for its expenses in providing distribution, promotional and/or shareholder services to Retirement Class shares at the annual rate of 0.05% of average daily net assets attributable to Retirement Class shares. In addition, TPIS has contractually agreed not to seek payment of this fee under the Plan for Retirement Class shares through September 30, 2012, unless changed with approval of the Board of Trustees.
[2]"Acquired Fund Fees and Expenses" are the Fund's proportionate amount of the expenses of any investment companies or pools in which it invests. These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly because they reduce Fund performance. Because "Acquired Fund Fees and Expenses" are included in the chart above, the Fund's operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund's May 31, 2011 annual report.
[3]In addition to the expense reimbursement arrangements, Advisors has contractually agreed to waive a portion of the Fund's Management Fees equal to, on an annual basis, 0.01%. This waiver will remain in effect through September 30, 2012, unless changed with approval of the Board of Trustees.
[4]Under the Fund's expense reimbursement arrangements, the Fund's investment adviser, Teachers Advisors, Inc. ("Advisors"), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.35% of average daily net assets for Retirement Class shares; (ii) 0.25% of average daily net assets for Premier Class shares; and (iii) 0.10% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 22% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 11% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have an approximate target retirement year in mind, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2020. The Fund has a policy of investing at least 80% of its assets (net assets, plus the amount of any borrowings for investment purposes) in Underlying Funds that are managed to seek investment returns that track particular market indices.


The Fund expects to allocate approximately 64.40% of its assets to equity Underlying Funds and 35.60% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, will gradually become more conservative, moving to target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2020 and reaching the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2027 to 2030. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 47.10%; International Equity: 15.70%; Fixed-Income: 34.40%; and Inflation-Protected Assets: 2.80%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Equity Index Fund (U.S. Equity); International Equity Index Fund and Emerging Markets Equity Index Fund (International Equity); Bond Index Fund (Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, or the Underlying Funds, typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Index Risk—The risk that an Underlying Fund’s performance will not correspond to its benchmark index for any period of time and may underperform such index or the overall stock market. Additionally, to the extent that an Underlying Fund’s investments vary from the composition of its benchmark index, an Underlying Fund’s performance could potentially vary from the index’s performance to a greater extent than if an Underlying Fund merely attempted to replicate the index.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.

· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

[1]The Retirement Class of the Fund has adopted a Distribution (12b-1) Plan that compensates the Fund's distributor, Teachers Personal Investors Services, Inc. ("TPIS"), for its expenses in providing distribution, promotional and/or shareholder services to Retirement Class shares at the annual rate of 0.05% of average daily net assets attributable to Retirement Class shares. In addition, TPIS has contractually agreed not to seek payment of this fee under the Plan for Retirement Class shares through September 30, 2012, unless changed with approval of the Board of Trustees.
[2]"Acquired Fund Fees and Expenses" are the Fund's proportionate amount of the expenses of any investment companies or pools in which it invests. These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly because they reduce Fund performance. Because "Acquired Fund Fees and Expenses" are included in the chart above, the Fund's operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund's May 31, 2011 annual report.
[3]In addition to the expense reimbursement arrangements, Advisors has contractually agreed to waive a portion of the Fund's Management Fees equal to, on an annual basis, 0.01%. This waiver will remain in effect through September 30, 2012, unless changed with approval of the Board of Trustees.
[4]Under the Fund's expense reimbursement arrangements, the Fund's investment adviser, Teachers Advisors, Inc. ("Advisors"), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.35% of average daily net assets for Retirement Class shares; (ii) 0.25% of average daily net assets for Premier Class shares; and (iii) 0.10% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 16% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 9% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have an approximate target retirement year in mind, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2025. The Fund has a policy of investing at least 80% of its assets (net assets, plus the amount of any borrowings for investment purposes) in Underlying Funds that are managed to seek investment returns that track particular market indices.


The Fund expects to allocate approximately 72.40% of its assets to equity Underlying Funds and 27.60% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, will gradually become more conservative, moving to target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2025 and reaching the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2032 to 2035. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income, and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 53.10%; International Equity: 17.70%; Fixed-Income: 28.40%; and Inflation-Protected Assets: 0.80%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Equity Index Fund (U.S. Equity); International Equity Index Fund and Emerging Markets Equity Index Fund (International Equity); Bond Index Fund (Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

The following chart shows how the investment glidepath for the Fund is expected to gradually move the Fund’s target allocations over time between the different target market sector allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks to achieve its final target market sector allocations approximately seven to ten years following the target date.

The Fund is designed to accommodate investors who invest in a fund up to their target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors should note that the Fund will continue to have a significant level of equity exposure up to, through and after its target retirement date, and this exposure could cause significant fluctuations in the value of the Fund depending on the performance of the equity markets generally.


Approximately seven to ten years after the Fund enters its target retirement year, the Board of Trustees may authorize the merger of the Fund into the Lifecycle Index Retirement Income Fund or other similar fund. Fund shareholders will receive prior notice of any such merger. The Lifecycle Index Retirement Income Fund is designed to maintain a relatively stable allocation among the Underlying Funds reflecting the resting point on the glidepath described in the chart above. More detailed information about the Lifecycle Index Retirement Income Fund is contained in the prospectus for that fund.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, or the Underlying Funds, typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Index Risk—The risk that an Underlying Fund’s performance will not correspond to its benchmark index for any period of time and may underperform such index or the overall stock market. Additionally, to the extent that an Underlying Fund’s investments vary from the composition of its benchmark index, an Underlying Fund’s performance could potentially vary from the index’s performance to a greater extent than if an Underlying Fund merely attempted to replicate the index.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.

There can be no assurances that the Fund or an Underlying Fund will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 16% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 9% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have an approximate target retirement year in mind, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2030. The Fund has a policy of investing at least 80% of its assets (net assets, plus the amount of any borrowings for investment purposes) in Underlying Funds that are managed to seek investment returns that track particular market indices.


The Fund expects to allocate approximately 80.40% of its assets to equity Underlying Funds and 19.60% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, will gradually become more conservative, moving to target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2030 and reaching the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2037 to 2040. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income, and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 59.10%; International Equity: 19.70%; Fixed-Income: 21.20%; and Inflation-Protected Assets: 0.00%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Equity Index Fund (U.S. Equity); International Equity Index Fund and Emerging Markets Equity Index Fund (International Equity); Bond Index Fund (Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

The Fund is designed to accommodate investors who invest in a fund up to their target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors should note that the Fund will continue to have a significant level of equity exposure up to, through and after its target retirement date, and this exposure could cause significant fluctuations in the value of the Fund depending on the performance of the equity markets generally.


Approximately seven to ten years after the Fund enters its target retirement year, the Board of Trustees may authorize the merger of the Fund into the Lifecycle Index Retirement Income Fund or other similar fund. Fund shareholders will receive prior notice of any such merger. The Lifecycle Index Retirement Income Fund is designed to maintain a relatively stable allocation among the Underlying Funds reflecting the resting point on the glidepath described in the chart above. More detailed information about the Lifecycle Index Retirement Income Fund is contained in the prospectus for that fund.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, or the Underlying Funds, typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Index Risk—The risk that an Underlying Fund’s performance will not correspond to its benchmark index for any period of time and may underperform such index or the overall stock market. Additionally, to the extent that an Underlying Fund’s investments vary from the composition of its benchmark index, an Underlying Fund’s performance could potentially vary from the index’s performance to a greater extent than if an Underlying Fund merely attempted to replicate the index.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.

There can be no assurances that the Fund or an Underlying Fund will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

[1]The Retirement Class of the Fund has adopted a Distribution (12b-1) Plan that compensates the Fund's distributor, Teachers Personal Investors Services, Inc. ("TPIS"), for its expenses in providing distribution, promotional and/or shareholder services to Retirement Class shares at the annual rate of 0.05% of average daily net assets attributable to Retirement Class shares. In addition, TPIS has contractually agreed not to seek payment of this fee under the Plan for Retirement Class shares through September 30, 2012, unless changed with approval of the Board of Trustees.
[2]"Acquired Fund Fees and Expenses" are the Fund's proportionate amount of the expenses of any investment companies or pools in which it invests. These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly because they reduce Fund performance. Because "Acquired Fund Fees and Expenses" are included in the chart above, the Fund's operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund's May 31, 2011 annual report.
[3]Under the Fund's expense reimbursement arrangements, the Fund's investment adviser, Teachers Advisors, Inc. ("Advisors"), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.35% of average daily net assets for Retirement Class shares; (ii) 0.25% of average daily net assets for Premier Class shares; and (iii) 0.10% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 10% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 10% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have an approximate target retirement year in mind, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2035. The Fund has a policy of investing at least 80% of its assets (net assets, plus the amount of any borrowings for investment purposes) in Underlying Funds that are managed to seek investment returns that track particular market indices.


The Fund expects to allocate approximately 88.40% of its assets to equity Underlying Funds and 11.60% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, will gradually become more conservative, moving to target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2035 and reaching the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2042 to 2045. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income, and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 65.10%; International Equity: 21.70%; Fixed-Income: 13.20%; and Inflation-Protected Assets: 0.00%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Equity Index Fund (U.S. Equity); International Equity Index Fund and Emerging Markets Equity Index Fund (International Equity); Bond Index Fund (Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, or the Underlying Funds, typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Index Risk—The risk that an Underlying Fund’s performance will not correspond to its benchmark index for any period of time and may underperform such index or the overall stock market. Additionally, to the extent that an Underlying Fund’s investments vary from the composition of its benchmark index, an Underlying Fund’s performance could potentially vary from the index’s performance to a greater extent than if an Underlying Fund merely attempted to replicate the index.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.

There can be no assurances that the Fund or an Underlying Fund will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

[1]The Retirement Class of the Fund has adopted a Distribution (12b-1) Plan that compensates the Fund's distributor, Teachers Personal Investors Services, Inc. ("TPIS"), for its expenses in providing distribution, promotional and/or shareholder services to Retirement Class shares at the annual rate of 0.05% of average daily net assets attributable to Retirement Class shares. In addition, TPIS has contractually agreed not to seek payment of this fee under the Plan for Retirement Class shares through September 30, 2012, unless changed with approval of the Board of Trustees.
[2]"Acquired Fund Fees and Expenses" are the Fund's proportionate amount of the expenses of any investment companies or pools in which it invests. These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly because they reduce Fund performance. Because "Acquired Fund Fees and Expenses" are included in the chart above, the Fund's operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund's May 31, 2011 annual report.
[3]Under the Fund's expense reimbursement arrangements, the Fund's investment adviser, Teachers Advisors, Inc. ("Advisors"), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.35% of average daily net assets for Retirement Class shares; (ii) 0.25% of average daily net assets for Premier Class shares; and (iii) 0.10% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 11% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 10% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have an approximate target retirement year in mind, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2040. The Fund has a policy of investing at least 80% of its assets (net assets, plus the amount of any borrowings for investment purposes) in Underlying Funds that are managed to seek investment returns that track particular market indices.


The Fund expects to allocate approximately 90.00% of its assets to equity Underlying Funds and 10.00% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, will gradually become more conservative, moving to target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2040 and reaching the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2047 to 2050. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income, and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 67.50%; International Equity: 22.50%; Fixed-Income: 10.00%; and Inflation-Protected Assets: 0.00%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Equity Index Fund (U.S. Equity); International Equity Index Fund and Emerging Markets Equity Index Fund (International Equity); Bond Index Fund (Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

The following chart shows how the investment glidepath for the Fund is expected to gradually move the Fund’s target allocations over time between the different target market sector allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks to achieve its final target market sector allocations approximately seven to ten years following the target date.

The Fund is designed to accommodate investors who invest in a fund up to their target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors should note that the Fund will continue to have a significant level of equity exposure up to, through and after its target retirement date, and this exposure could cause significant fluctuations in the value of the Fund depending on the performance of the equity markets generally.


Approximately seven to ten years after the Fund enters its target retirement year, the Board of Trustees may authorize the merger of the Fund into the Lifecycle Index Retirement Income Fund or other similar fund. Fund shareholders will receive prior notice of any such merger. The Lifecycle Index Retirement Income Fund is designed to maintain a relatively stable allocation among the Underlying Funds reflecting the resting point on the glidepath described in the chart above. More detailed information about the Lifecycle Index Retirement Income Fund is contained in the prospectus for that fund.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, or the Underlying Funds, typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Index Risk—The risk that an Underlying Fund’s performance will not correspond to its benchmark index for any period of time and may underperform such index or the overall stock market. Additionally, to the extent that an Underlying Fund’s investments vary from the composition of its benchmark index, an Underlying Fund’s performance could potentially vary from the index’s performance to a greater extent than if an Underlying Fund merely attempted to replicate the index.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.

There can be no assurances that the Fund or an Underlying Fund will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

("Advisors"), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.35% of average daily net assets for Retirement Class shares; (ii) 0.25% of average daily net assets for Premier Class shares; and (iii) 0.10% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 10% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 11% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have an approximate target retirement year in mind, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2045. The Fund has a policy of investing at least 80% of its assets (net assets, plus the amount of any borrowings for investment purposes) in Underlying Funds that are managed to seek investment returns that track particular market indices.


The Fund expects to allocate approximately 90.00% of its assets to equity Underlying Funds and 10.00% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, will gradually become more conservative, moving to target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2045 and reaching the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2052 to 2055. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income, and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 67.50%; International Equity: 22.50%; Fixed-Income: 10.00%; and Inflation-Protected Assets: 0.00%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Equity Index Fund (U.S. Equity); International Equity Index Fund and Emerging Markets Equity Index Fund (International Equity); Bond Index Fund (Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

The following chart shows how the investment glidepath for the Fund is expected to gradually move the Fund’s target allocations over time between the different target market sector allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks to achieve its final target market sector allocations approximately seven to ten years following the target date.

The Fund is designed to accommodate investors who invest in a fund up to their target retirement date, and plan to make gradual systematic withdrawals in retirement. In addition, investors should note that the Fund will continue to have a significant level of equity exposure up to, through and after its target retirement date, and this exposure could cause significant fluctuations in the value of the Fund depending on the performance of the equity markets generally.


Approximately seven to ten years after the Fund enters its target retirement year, the Board of Trustees may authorize the merger of the Fund into the Lifecycle Index Retirement Income Fund or other similar fund. Fund shareholders will receive prior notice of any such merger. The Lifecycle Index Retirement Income Fund is designed to maintain a relatively stable allocation among the Underlying Funds reflecting the resting point on the glidepath described in the chart above. More detailed information about the Lifecycle Index Retirement Income Fund is contained in the prospectus for that fund.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, or the Underlying Funds, typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Index Risk—The risk that an Underlying Fund’s performance will not correspond to its benchmark index for any period of time and may underperform such index or the overall stock market. Additionally, to the extent that an Underlying Fund’s investments vary from the composition of its benchmark index, an Underlying Fund’s performance could potentially vary from the index’s performance to a greater extent than if an Underlying Fund merely attempted to replicate the index.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.

There can be no assurances that the Fund or an Underlying Fund will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

[1]The Retirement Class of the Fund has adopted a Distribution (12b-1) Plan that compensates the Fund's distributor, Teachers Personal Investors Services, Inc. ("TPIS"), for its expenses in providing distribution, promotional and/or shareholder services to Retirement Class shares at the annual rate of 0.05% of average daily net assets attributable to Retirement Class shares. In addition, TPIS has contractually agreed not to seek payment of this fee under the Plan for Retirement Class shares through September 30, 2012, unless changed with approval of the Board of Trustees.
[2]"Acquired Fund Fees and Expenses" are the Fund's proportionate amount of the expenses of any investment companies or pools in which it invests. These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly because they reduce Fund performance. Because "Acquired Fund Fees and Expenses" are included in the chart above, the Fund's operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund's May 31, 2011 annual report.
[3]Under the Fund's expense reimbursement arrangements, the Fund's investment adviser, Teachers Advisors, Inc. ("Advisors"), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.35% of average daily net assets for Retirement Class shares; (ii) 0.25% of average daily net assets for Premier Class shares; and (iii) 0.10% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter.

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 11% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 12% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have an approximate target retirement year in mind, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2050. The Fund has a policy of investing at least 80% of its assets (net assets, plus the amount of any borrowings for investment purposes) in Underlying Funds that are managed to seek investment returns that track particular market indices.


The Fund expects to allocate approximately 90.00% of its assets to equity Underlying Funds and 10.00% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, will gradually become more conservative, moving to target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2050 and reaching the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2057 to 2060. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed-income, and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 67.50%; International Equity: 22.50%; Fixed-Income: 10.00%; and Inflation-Protected Assets: 0.00%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Equity Index Fund (U.S. Equity); International Equity Index Fund and Emerging Markets Equity Index Fund (International Equity); Bond Index Fund (Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

In addition, investors should note that the Fund will continue to have a significant level of equity exposure up to, through and after its target retirement date, and this exposure could cause significant fluctuations in the value of the Fund depending on the performance of the equity markets generally.


Approximately seven to ten years after the Fund enters its target retirement year, the Board of Trustees may authorize the merger of the Fund into the Lifecycle Index Retirement Income Fund or other similar fund. Fund shareholders will receive prior notice of any such merger. The Lifecycle Index Retirement Income Fund is designed to maintain a relatively stable allocation among the Underlying Funds reflecting the resting point on the glidepath described in the chart above. More detailed information about the Lifecycle Index Retirement Income Fund is contained in the prospectus for that fund.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, or the Underlying Funds, typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Index Risk—The risk that an Underlying Fund’s performance will not correspond to its benchmark index for any period of time and may underperform such index or the overall stock market. Additionally, to the extent that an Underlying Fund’s investments vary from the composition of its benchmark index, an Underlying Fund’s performance could potentially vary from the index’s performance to a greater extent than if an Underlying Fund merely attempted to replicate the index.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Special Risks for Inflation-Indexed Bonds—The risk that interest payments on, or market values of, inflation-indexed investments decline because of a decline in inflation (or deflation) or changes in investors’ and/or the market’s inflation expectations. In addition, inflation indices may not reflect the true rate of inflation.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.

There can be no assurances that the Fund or an Underlying Fund will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Retirement Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Retirement Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Retirement Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Retirement, Institutional and Premier Classes over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for the Retirement Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Retirement Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.

[1]The Retirement Class of the Fund has adopted a Distribution (12b-1) Plan that compensates the Fund's distributor, Teachers Personal Investors Services, Inc. ("TPIS"), for its expenses in providing distribution, promotional and/or shareholder services to Retirement Class shares at the annual rate of 0.05% of average daily net assets attributable to Retirement Class shares. In addition, TPIS has contractually agreed not to seek payment of this fee under the Plan for Retirement Class shares through September 30, 2012, unless changed with approval of the Board of Trustees.
[2]Other Expenses are estimates for the current fiscal year.
[3]"Acquired Fund Fees and Expenses" are the Fund's proportionate amount of the expenses of any investment companies or pools in which it invests. These expenses are not paid directly by Fund shareholders. Instead, Fund shareholders bear these expenses indirectly because they reduce Fund performance. Because "Acquired Fund Fees and Expenses" are included in the chart above, the Fund's operating expenses here will not correlate with the expenses included in the Financial Highlights in this Prospectus and the Fund's May 31, 2011 annual report.
[4]Under the Fund's expense reimbursement arrangements, the Fund's investment adviser, Teachers Advisors, Inc. ("Advisors"), has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.35% of average daily net assets for Retirement Class shares; (ii) 0.25% of average daily net assets for Premier Class shares; and (iii) 0.10% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least September 30, 2012, unless changed with approval of the Board of Trustees.
Example

This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, before expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement agreement will remain in place through September 30, 2012 but that there will be no waiver or expense reimbursement agreement in effect thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the one-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 1% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of the TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). In general, the Fund is designed for investors who have an approximate target retirement year in mind, and the Fund’s investments are adjusted from more aggressive to more conservative over time as the target retirement year approaches and for approximately seven to ten years afterwards. The Fund invests in Underlying Funds according to an asset allocation strategy designed for investors retiring or planning to retire within a few years of 2055.


The Fund expects to allocate approximately 90.00% of its assets to equity Underlying Funds and 10.00% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations will change over time and actual allocations may vary up to 10% from the targets. The target allocations along the investment glidepath, illustrated in the chart below, will gradually become more conservative, moving to target allocations of approximately 50% equity/50% fixed-income in The Fund’s target retirement year of 2055 and reaching the Fund’s final target allocation of approximately 40% equity/60% fixed-income at some point from 2062 to 2065. Within the equity and fixed-income asset classes, the Fund allocates its investments to particular market sectors (U.S. equity, international equity, fixed income and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Fund’s target market sector allocations. The Fund’s current target market sector allocations for June 30, 2012, which will change over time, are approximately as follows: U.S. Equity: 67.50%; International Equity: 22.50%; Fixed-Income: 10.00%; and Inflation-Protected Assets: 0.00%.


The Fund’s target market sector allocations to Underlying Funds may include the TIAA-CREF Equity Index Fund (U.S. Equity); International Equity Index Fund and Emerging Markets Equity Index Fund (International Equity); Bond Index Fund (Fixed-Income); and Inflation-Linked Bond Fund (Inflation-Protected Assets).


Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Fund’s desired levels of risk and potential return at the particular time. The Fund’s portfolio management team may also add a new market sector if it believes that will help to achieve the Fund’s investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of a Fund’s assets are expected to be invested in any Underlying Fund or market sectors not listed above, shareholders will receive prior notice of such change.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

The following chart shows how the investment glidepath for the Fund is expected to gradually move the Fund’s target allocations over time between the different target market sector allocations. The actual market sector allocations of the Fund may differ from this chart. The Fund seeks to achieve its final target market sector allocations approximately seven to ten years following the target date.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 21% of the average value of its portfolio. During the eight-month fiscal period ended May 31, 2011, the Fund’s portfolio turnover rate was 10% (not annualized) of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund is a “fund of funds” that invests in Institutional Class shares of other funds of TIAA-CREF Funds and potentially in other investment pools or investment products (collectively, the “Underlying Funds”). The Fund invests in Underlying Funds according to a relatively stable asset allocation strategy and will generally seek to meet its investment objective by investing: (1) approximately 60% of its assets in equity Underlying Funds including up to 5% of its assets in real estate Underlying Funds; and (2) approximately 40% of its assets in fixed-income Underlying Funds (“target allocations”).


The Fund currently intends to invest in the following equity Underlying Funds: Growth & Income Fund, International Equity Fund, Large-Cap Growth Fund, Large-Cap Value Fund, Mid-Cap Growth Fund, Mid-Cap Value Fund, Emerging Markets Equity Fund, Small-Cap Equity Fund, Enhanced International Equity Index Fund, Enhanced Large-Cap Growth Index Fund, Enhanced Large-Cap Value Index Fund and Real Estate Securities Fund.


The Fund currently intends to invest in the following fixed-income Underlying Funds: Bond Plus Fund, Short-Term Bond Fund, High-Yield Fund and Inflation-Linked Bond Fund


As a result of its investments in the Underlying Funds, the Managed Allocation Fund’s returns will reflect investments in a mix of domestic stocks of companies of all sizes, foreign equities, real estate securities and a variety of domestic and foreign fixed-income instruments of private and governmental issuers of varying maturities and credit qualities. To maintain an appropriate allocation among the Underlying Funds, the portfolio managers monitor the foreign and domestic equity markets, as well as overall financial and economic conditions. If the portfolio managers believe that the relative attractiveness of the markets in which the equity and fixed-income funds are invested changes, they can adjust the percentage of investments in these Underlying Funds up or down by up to 10%. At any given time the Fund may hold between 0 to 5% of its assets in real estate funds. The Fund’s composite benchmark is a composite of three benchmark indices representing three types of market sectors within the equity and fixed-income Underlying Fund asset classes, i.e., domestic equity, international equity and fixed-income. The composite index is created by applying the results of the benchmark for each of these three market sectors in proportion to the Fund’s target allocations among the three market sectors. For more information about the different indices that comprise the Fund’s composite benchmark index, please see “Additional Information About the Fund’s Composite Index” below.


The composition of the Fund’s fixed-income portion will vary depending on the shape of the yield curve. This means that when there is not much difference between the yield on short-term and long-term bonds, the Fund would normally increase its investments in the Short-Term Bond Fund. The Fund will have less than 5% of its assets in the High-Yield Fund.


The Fund might sometimes be even more heavily weighted toward equities or fixed-income, if Advisors believes market conditions warrant. For example, the Fund might increase its holdings in fixed-income funds in periods when Advisors believes equity markets will decline.


As part of the Fund’s ability to invest in unaffiliated investment products or pools noted above, the Board has authorized the Fund to invest in exchange-traded funds (“ETFs”) and exchange-traded notes (“ETNs”). The Fund may use investments in ETFs and ETNs to gain exposure to various market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund may use ETFs and ETNs for cash management, hedging or defensive purposes. ETFs and ETNs will be subject to the risks associated with the types of securities or sectors that they track, while ETNs, which are structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, including credit risk.


For flexibility in meeting redemptions, expenses and the timing of new investments, and as a short-term defense during periods of unusual volatility, the Fund may invest in government securities (as defined in the Investment Company Act of 1940, as amended (the “1940 Act”)), short-term paper or shares of the Money Market Fund. For temporary defensive purposes, the Managed Allocation Fund may invest without limitation in such securities. The Fund cannot guarantee that this strategy will be successful.


The Fund’s asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2011, are listed in the chart below. These allocations will change over time.

PRINCIPAL INVESTMENT RISKS

You could lose money over short or long periods by investing in this Fund. Accordingly, an investment in the Fund, or the Underlying Funds, typically is subject to the following principal investment risks:


· Asset Allocation Risk—The risk that the Fund may not achieve its target allocations. In addition, there is the risk that the asset allocations may not achieve the desired risk-return characteristic or that the selection of Underlying Funds and the allocations among them will result in the Fund underperforming other similar funds or cause an investor to lose money.


· Equity Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in equity investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in equity investments. Equity investments generally have greater price volatility than fixed income instruments.


· Market Risk—The risk that market prices of investments held by an Underlying Fund may fall rapidly or unpredictably due to a variety of factors, including changing economic, political or market conditions. Market risk may affect a single issuer, industry or sector of the economy, or it may affect the market as a whole.


· Issuer Risk (often called Financial Risk)—The risk that the issuer’s earnings prospects and overall financial position will deteriorate, causing a decline in the value of its financial instruments over short or extended periods of time.


· Style Risk—The risk that use of a particular investing style (such as growth or value investing) may fall out of favor in the marketplace for various periods of time and result in underperformance relative to the broader market sector or significant declines in the value of an Underlying Fund’s portfolio securities.


· Risks of Growth Investing—The risks that growth stocks can perform differently from the market as a whole and other types of stocks. Growth stocks can also be more volatile, and experience sharper price fluctuations, than other stocks.


· Risks of Value Investing—The risks that value stocks can perform differently from the market as a whole and other types of stocks. Value stocks can also continue to be undervalued by the market for long periods of time.


· Large-Cap Risk—The risk that large-capitalization companies are more mature and may grow more slowly than the economy as a whole and tend to go in and out of favor based on market and economic conditions.


· Mid-Cap Risk—The risk that the stocks of mid-capitalization companies often have greater price volatility, lower trading volume and less liquidity than the stocks of larger, more established companies.


· Small-Cap RiskThe risk that the stocks of small-capitalization companies often experience greater price volatility than large- or mid-sized companies because small-cap companies are often newer or less established than larger companies and are likely to have more limited resources, products and markets. Securities of small-cap companies are often less liquid than securities of larger companies as a result of there being a smaller market for their securities.


· Foreign Investment Risk—Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, currency, market or economic developments and can result in greater price volatility and perform differently from financial instruments of U.S. issuers. This risk may be heightened in emerging or developing markets. Foreign investments may also be less liquid and more difficult to value than investments in U.S. issuers.


· Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets. For example, these countries may have more unstable governments than developed countries, and their economies may be based on only a few industries. Because their financial markets may be very small, share prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may be less liquid than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many such countries.


· Enhanced Index Risk—Certain Underlying Funds that are enhanced index funds may underperform their benchmark index due to differences between the investments of the Underlying Funds and their respective benchmark indices.


· Quantitative Analysis Risk—The risk that stocks selected by the Fund’s or an Underlying Fund’s investment adviser using quantitative modeling and analysis could perform differently from the market as a whole.


· Fixed-Income Investments Risk—A significant portion of the assets of the Fund is allocated to Underlying Funds investing primarily in fixed-income investments. Therefore, the value of the Fund may increase or decrease as a result of its indirect interest in fixed-income investments.


· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments declines in certain interest rate environments.


· Credit Risk (a type of Issuer Risk)—The risk that the issuer of bonds may not be able or willing to meet interest or principal payments when the bonds become due.


· Market Volatility, Liquidity and Valuation Risk (types of Market Risk)—The risk that volatile or dramatic reductions in trading activity make it difficult for an Underlying Fund to properly value its investments and that an Underlying Fund may not be able to purchase or sell an investment at an attractive price, if at all.


· Call Risk—The risk that, during periods of falling interest rates, an issuer may call (or repay) a fixed-income security prior to maturity, resulting in a decline in an Underlying Fund’s income.


· Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income investments to decline. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments.


· Prepayment Risk—The risk that during periods of falling interest rates, borrowers may pay off their mortgage loans sooner than expected, forcing an Underlying Fund to reinvest the unanticipated proceeds at lower interest rates and resulting in a decline in income.


· Extension Risk—The risk that during periods of rising interest rates, borrowers may pay off their mortgage loans later than expected, preventing an Underlying Fund from reinvesting principal proceeds at higher interest rates and resulting in less income than potentially available.


· Active Management Risk—The risk that the strategy, investment selection or trading execution of Advisors could cause the Fund or an Underlying Fund to underperform its benchmark index or mutual funds with similar investment objectives.


· Underlying Fund Risk—The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no guarantee that any Underlying Fund will achieve its investment objective.


· Derivatives Risk—The risks associated with investing in derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments. An Underlying Fund may use futures and options, and an Underlying Fund may also use more complex derivatives such as swaps that might present liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested.

There can be no assurances that the Fund or an Underlying Fund’s will achieve its investment objective. You should not consider the Fund to be a complete investment program. Please see the non-summary portion of the prospectus for more detailed information about the risks described above.

PAST PERFORMANCE

The following chart and table help illustrate some of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year. The bar chart shows the annual total returns of the Institutional Class of the Fund, before taxes, in each full calendar year since inception of the class. Because the expenses vary across share classes, the performance of the Institutional Class will vary from the other share classes. Below the bar chart are the best and worst returns for a calendar quarter since inception of the Institutional Class. The performance table following the bar chart shows the Fund’s average annual total returns for the Institutional Class, Retail Class and Retirement Class over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2010, and how those returns compare to those of a broad-based securities market index and a composite index based on the Fund’s target allocations. After-tax performance is shown only for Institutional Class shares, and after-tax returns for the other Classes of shares will vary from the after-tax returns presented for Institutional Class shares.


The returns shown below reflect previous agreements by the Fund’s investment adviser to waive or reimburse the Fund and certain Underlying Funds for certain fees and expenses. Without these waivers and reimbursements, the returns of the Fund would have been lower. Past performance of the Fund (before and after taxes) is not necessarily an indication of how it will perform in the future. The indices listed below are unmanaged, and you cannot invest directly in an index. The returns for the indices reflect no deduction for fees, expenses or taxes.
