ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment)¹

		Institutional Class
Management Fees		0.40%
Other Expenses		0.04%
Total Annual Fund Operating Expenses		0.44%
Waivers and Expense Reimbursements2		—
Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement		0.44%
1	Expense information has been restated to reflect an amendment to the Fund’s investment management agreement effective March 1, 2015.
2	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) 0.50% of average daily net assets for Institutional Class shares of the Fund. These expense reimbursement arrangements will continue through at least February 29, 2016, 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 29, 2016, 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:

	Institutional Class
1 Year	$	45
3 Years	$	141
5 Years	$	246
10 Years	$	555

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, 2014, the Fund’s portfolio turnover rate was 71% of the average value of its portfolio.

Principal investment strategies

Under normal circumstances, the Fund invests at least 80% of its assets in equity securities of foreign issuers included in the Fund’s benchmark index, the MSCI EAFE^®Index, at the time of purchase, but not necessarily at index weightings. The Fund has a policy of maintaining investments of equity securities of foreign issuers in at least three countries other than the United States. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.

The Fund follows an enhanced index management strategy. The Fund’s investment adviser, Teachers Advisors, Inc. (“Advisors”), actively uses quantitative analysis to attempt to enhance the Fund’s performance relative to the MSCI EAFE^®Index while retaining a similar risk profile, instead of passively holding a representative basket of securities designed to match the index. The MSCI EAFE^®Index measures stock performance in certain countries outside North America.

Enhanced index strategies employ quantitative modeling techniques for stock selection, country allocation and portfolio construction. With enhanced indexing, the Fund may use several different investment techniques to seek to build a portfolio of stocks that is structured to resemble and share the risk characteristics of the Fund’s benchmark index, while also seeking to outperform the benchmark index. Enhanced indexing is designed so that the Fund diverges from its benchmark index more than a pure indexing strategy, with the goal of outperforming its benchmark index while effectively managing benchmark relative risks.

Under these quantitative modeling techniques, a number of variables related to individual stocks are evaluated to select a broadly diversified group of stocks that may have the potential to provide a higher total return than that of the benchmark index, the MSCI EAFE^®Index. The Fund uses a proprietary, quantitative stock scoring model to evaluate and score a broad universe of stocks in which the Fund invests.

Advisors will generally attempt to overweight securities (relative to the benchmark) that score high in the stock selection screening process and to either not hold or underweight securities that score low in the screening process. The Fund may also purchase and sell swaps and other equity derivatives to carry out the Fund’s investment strategies. The Fund’s strategy is based upon Advisors’ understanding of the interplay of market factors and does not assure successful investment. The markets or the process of selecting individual securities may be affected by factors not taken into account in Advisors’ analysis.

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:

TIAA-CREF Enhanced International Equity Index Fund■Summary Prospectus     3

·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.

·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.

·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.

·Enhanced Index Risk—As an enhanced index fund, the Fund may also underperform its benchmark index due to differences between the investments of the Fund and its benchmark index.

·Quantitative Analysis Risk—The risk that stocks selected using quantitative modeling and analysis could perform differently from the market as a whole.

·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, options, single name or index credit default swaps, or forwards, 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.

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 Institutional Class. 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 over the one-year, five-year, ten-year and since-inception periods (where applicable) ended December 31, 2014, and how those returns compare to those of the Fund’s benchmark index.

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.
