1 Under the Fund’s expense reimbursement arrangements, the Fund’s investment adviser, Teachers Advisors, LLC, 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) 0.22% of average daily net assets for Institutional Class shares; (ii) 0.37% of average daily net assets for Advisor Class shares; (iii) 0.37% of average daily net assets for Premier Class shares; (iv) 0.47% of average daily net assets for Retirement Class shares; and (v) 0.61% of average daily net assets for Retail Class shares of the Fund. These expense reimbursement arrangements will continue through at least February 28, 2023, 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 fee waivers and/or expense reimbursements, remain the same. The example assumes that the Fund’s fee waiver and/or expense reimbursement arrangements will each remain in place for the duration noted in the table above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	Institutional Class		Advisor Class		Premier Class		Retirement Class		Retail Class
1 year	$	17	$	26	$	34	$	43	$	45
3 years	$	55	$	80	$	106	$	135	$	141
5 years	$	96	$	141	$	185	$	235	$	246
10 years	$	217	$	318	$	418	$	530	$	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.

TIAA-CREF Social Choice Equity Fund ■Summary Prospectus 3

During the fiscal year ended October 31, 2021, the Fund’s portfolio turnover rate was 27% 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. The Fund attempts to achieve the return of the U.S. stock market as represented by its benchmark, the Russell 3000^®Index, while taking into consideration certain ESG criteria. See “Additional information about the Fund’s benchmark index” in the non-summary portion of the Prospectus for more information about the Fund’s benchmark. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.

When selecting investments for the Fund, Teachers Advisors, LLC (“Advisors”), the Fund’s investment adviser, considers certain ESG criteria. The ESG criteria are generally implemented based on data provided by independent research vendor(s). The evaluation process favors companies with leadership in ESG performance relative to their peers. Typically, environmental assessment categories include climate change, natural resource use, waste management and environmental opportunities. Social evaluation categories include human capital, product safety and social opportunities. Governance assessment categories include corporate governance, business ethics and government and public policy. How well companies adhere to international norms and principles and involvement in major ESG controversies (examples of which may relate to the environment, customers, human rights and community, labor rights and supply chain, and governance) are other considerations.

The ESG evaluation process is conducted on an industry-specific basis and involves the identification of key performance indicators, which are given more or less relative weight compared to the broader range of potential assessment categories. When ESG concerns exist, the evaluation process gives careful consideration to how companies address the risks and opportunities they face in the context of their sector or industry and relative to their peers. The Fund will not generally invest in companies significantly involved in certain business activities, including but not limited to the production of alcohol, tobacco, military weapons, firearms, nuclear power, thermal coal and gambling products and services.

After the ESG evaluation process is conducted, Advisors then uses quantitative investment techniques to attempt to closely match, to the extent practicable, the overall risk characteristics of the benchmark index. Under these quantitative investment techniques, the Fund uses a risk model to evaluate the stocks in which the Fund may invest and to inform the construction of a broadly diversified group of stocks.

While Advisors generally invests in companies that meet the ESG criteria, it is not required to invest in every company that meets these criteria. In addition, concerns with respect to one ESG assessment category may not automatically eliminate an issuer from being considered an eligible Fund investment. The ESG

4Summary Prospectus■TIAA-CREF Social Choice Equity Fund

criteria the Fund takes into consideration are non-fundamental investment policies and may be changed without the approval of the Fund’s shareholders.

The Board of Trustees of the Trust or a designated committee thereof (“Board of Trustees”) reviews the ESG criteria used to evaluate securities held by the Fund and approves the ESG vendor(s) that provide the data that help inform these criteria. Consistent with its responsibilities, the Board of Trustees evaluates options for implementing the Fund’s ESG investment criteria and monitors the ESG vendor(s) selected to supply the ESG data. Advisors has the right to change the ESG vendor(s) at any time and to add to the number of vendors providing the ESG data.

Investing on the basis of ESG criteria is qualitative and subjective by nature. There can be no assurance that every Fund investment will meet ESG criteria, or will do so at all times, or that the ESG criteria or any judgment exercised by Advisors will reflect the beliefs or values of any particular investor.

The Fund is not restricted from investing in any securities issued or guaranteed by the U.S. government or its agencies or instrumentalities. The Fund may also invest in securities issued by other countries or their agencies or instrumentalities as approved by the Board of Trustees. The Fund may invest up to 15% of its assets in foreign investments.

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:

·ESG Risk—The risk that because the Fund’s ESG criteria exclude securities of certain issuers for nonfinancial reasons, the Fund may forgo some market opportunities available to funds that do not use these criteria.

·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. From time to time, the Fund may invest a significant portion of its assets in companies in one or more related sectors or industries, which would make the Fund more vulnerable to adverse developments affecting such sectors or industries.

·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

TIAA-CREF Social Choice Equity Fund ■Summary Prospectus 5

investments may also have lower liquidity and be more difficult to value than investments in U.S. issuers. Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, less public information, less stringent investor protections and less stringent accounting, corporate governance, financial reporting and disclosure standards.

·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 experience greater price volatility, lower trading volume and lower overall liquidity than the stocks of larger, more established companies.

·Small-Cap Risk—The 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 often have lower overall liquidity than securities of larger companies as a result of there being a smaller market for their securities, which can have an adverse effect on the pricing of these securities and on the ability to sell these securities when Advisors deems it appropriate.

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

·Benchmark Risk—The risk that the Fund’s performance may not correspond to its benchmark index for any period of time and may underperform such index or the overall financial 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.

·Quantitative Analysis Risk—The risk that stocks selected using quantitative modeling and analysis could perform differently from the market as a whole and the risk that such quantitative analysis and modeling may not adequately take into account certain factors, may contain design flaws or inaccurate assumptions and may rely on inaccurate data inputs, which may result in losses to the Fund.

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,

6Summary Prospectus■TIAA-CREF Social Choice Equity 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 may 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 full calendar-year periods covered by the bar chart. The performance table following the bar chart shows the Fund’s average annual total returns for the Institutional, Advisor, Premier, Retirement and Retail classes over the applicable one-year, five-year, ten-year and since-inception periods ended December 31, 2021, 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 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 an index. The returns for the benchmark index reflect no deduction for fees, expenses or taxes.

#	The performance shown for the Advisor Class that is prior to its inception date is based on performance of the Institutional Class. The performance for these periods has not been restated to reflect the actual expenses of the Advisor Class. If these actual expenses had been reflected, the performance of the Advisor Class shown for these periods would have been different because the Advisor Class has different expenses than the Institutional Class.
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.
