	Retail Class	Retirement Class	Premier Class	Institutional Class

¹The 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 providing distribution, promotional and shareholder services to the Retail Class shares at the annual rate of up to 0.25% of average daily net assets attributable to Retail Class shares. Because reimbursements are currently below the Retail Plan’s maximum rate, the fees shown in the chart for the Plan are estimated reimbursements for the current year.

²Under 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) 0.75% of average daily net assets for Retail Class shares; (ii) 0.65% of average daily net assets for Retirement Class shares; (iii) 0.55% of average daily net assets for Premier Class shares; and (iv) 0.40% 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:

	Retail Class		Retirement Class		Premier Class		Institutional Class
1 Year	$	61	$	66	$	56	$	41
3 Years	$	192	$	209	$	177	$	130
5 Years	$	335	$	366	$	311	$	228
10 Years	$	750	$	821	$	699	$	516

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

2     Summary Prospectus■TIAA-CREF High-Yield Fund

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.

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 other 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, 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 should, 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.

Advisors may from time to time share investment research and ideas about high-yield securities with its affiliate, Teachers Insurance and Annuity Association of America (“TIAA”). While Advisors believes that such sharing of information provides benefits to the Fund and its shareholders, the Fund may at times be prevented from buying or selling certain securities or may need to sell certain securities before it may otherwise do so, in order to comply with the federal securities laws.

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, or the Fund’s portfolio securities, 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 weak financial health and such securities can be harder to value and sell and their prices can be more volatile.

·Interest Rate Risk (a type of Market Risk)—The risk that increases in interest rates can cause the prices of fixed-income securities to decline.

·Company 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 the security 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 the portfolio securities in which it invests and that the Fund may not be able to purchase or sell a security at an attractive price, if at all.

·Fixed-Income Foreign Investment Risk—Investment in fixed-income securities 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.

·Active Management Risk—The risk that securities selection by the Fund’s investment adviser could cause the Fund to underperform its benchmark index or mutual funds with similar investment objectives.

4     Summary Prospectus■TIAA-CREF High-Yield Fund

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

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. For current performance information of each share class, including performance to the most recent month-end, please visit www.tiaa-cref.org.

Current performance of the Fund’s shares may be higher or lower than that shown above.

*The performance shown for the Premier Class that is prior to its inception date is based on performance of the Fund’s Institutional Class. The performance for these periods has not been restated to reflect higher expenses of the Premier Class. If those expenses had been reflected, the performance would have been lower.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates in effect during the periods shown and do not reflect the impact of state and local taxes. Actual after-tax returns depend on the investor’s tax situation and may differ from those shown. The after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements such as 401(a), 401(k) or 403(b) plans or Individual Retirement Accounts (IRAs). After-tax returns are shown for only one class and after-tax returns for other classes will vary.
