ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment)

		Retirement Class	Institutional Class
Management Fees		0.04%	0.04%
Other Expenses		0.28%	0.03%
Total Annual Fund Operating Expenses		0.32%	0.07%
Waivers and Expense Reimbursements1		—	—
Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement		0.32%	0.07%
1	Under the Fund’s expense reimbursement arrangements, the Fund’s investment adviser, Teachers Advisors, Inc., has contractually agreed to reimburse the Fund for any Total Annual Fund Operating Expenses (excluding interest, taxes, brokerage commissions or other transactional expenses, Acquired Fund Fees and Expenses and extraordinary expenses) that exceed: (i) 0.34% of average daily net assets for Retirement Class shares; and (ii) 0.09% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least February 28, 2015, 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 February 28, 2015, 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:

	Retirement Class		Institutional Class
1 Year	$	33	$	7
3 Years	$	103	$	23
5 Years	$	180	$	40
10 Years	$	406	$	90

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 October 31, 2013, the Fund’s portfolio turnover rate was 19% of the average value of its portfolio.

Principal investment strategies

Under normal circumstances, the Fund invests at least 80% of its assets in securities of its benchmark index (Russell 1000^®Growth Index). For purposes of the 80% investment policy, “large-cap” securities are securities of issuers with a capitalization equal to or greater than the top 80% of issuers by capitalization within the Russell 1000^®Index at the time of purchase. The Fund buys most, but not necessarily all, of the stocks in its benchmark index, and will attempt to closely match the overall investment characteristics of its benchmark index. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.

The Fund is designed to track various U.S. equity markets as a whole or a segment of these markets. The Fund primarily invests its assets in equity securities selected to track a designated stock market index. Because the return of an index is not reduced by investment and other operating expenses, the Fund’s ability to match its index is negatively affected by the costs of buying and selling securities as well as the Fund’s fees and other expenses. The use of a particular index by the Fund is not a fundamental policy and may be changed without shareholder approval. The portfolio management team of the Fund’s investment adviser, Teachers Advisors, Inc. (“Advisors”), will attempt to build a portfolio that generally matches the market weighted investment characteristics of the Fund’s benchmark index.

Principal investment risks

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

·Market Risk—The risk that market prices of portfolio 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 sector of the economy, or it may affect the market as a whole.

·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.

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

·Style Risk—The risk that use of a particular investing style (such as growth or valueinvesting) may fall out of favor in the marketplace for various periods of time and result in underperformance relative to the broader

TIAA-CREF Large-Cap Growth Index Fund■Summary Prospectus     3

market sector or significant declines in the value of the Fund’s portfolio investments.

·Risks of Growth Investing—Due to their relatively high valuations, growth stocks are typically more volatile than value stocks and may experience a larger decline on a forecast of lower earnings, or a negative event or market development, than would a value stock.

·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.

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. Below the bar chart are the best and worst returns of the Institutional Class for a calendar quarter during the period covered by the bar chart. The performance table following the bar chart shows the Fund’s average annual total returns for the Institutional Class and Retirement Class over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2013, 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 Retirement Class shares will vary from the after-tax returns presented for the Institutional Class shares.

The returns shown below reflect previous agreements by Advisors 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 benchmark index. The returns for the benchmark index reflect no deduction for fees, expenses or taxes.
