The Fund seeks a favorable long-term total return, mainly through capital appreciation, primarily from equity securities of smaller domestic companies.

Expense [Heading] rr_ExpenseHeading Fees and expenses
Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.
Shareholder Fees Caption [Text] rr_ShareholderFeesCaption SHAREHOLDER FEES (fees paid directly from your investment)
Operating Expenses Caption [Text] rr_OperatingExpensesCaption ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment)
Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio turnover
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

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, 2023, the Fund’s portfolio turnover rate was 75% of the average value of its portfolio.

Expense Example [Heading] rr_ExpenseExampleHeading Example
Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

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 durations noted in the table above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading] rr_StrategyHeading Principal investment strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its assets in small-cap equity securities. In seeking a favorable long-term total return, the Fund will invest in securities that the Fund’s investment adviser, Teachers Advisors,

LLC (“Advisors”), believes have favorable prospects for significant long-term capital appreciation potential. A “small-cap” equity security is a security within the capitalization range of the companies included in the Fund’s benchmark index, the Russell 2000® Index, at the time of purchase. The Fund invests primarily in equity securities of smaller domestic companies across a wide range of sectors, growth rates and valuations. For purposes of the 80% investment policy, the term “assets” means net assets, plus the amount of any borrowings for investment purposes.

The Fund seeks to add incremental return over its stated benchmark index, while also managing the relative risk of the Fund versus its benchmark index. Advisors uses proprietary quantitative models, or models utilizing econometric and mathematical techniques, based on financial and investment theories to evaluate and score a broad universe of stocks in which the Fund invests. These models typically weigh many different variables, including the valuation of the individual stock versus the market or its peers, future earnings and sustainable growth prospects, and the price and volume trends of the stock. The score is used to form the portfolio and the following additional inputs may also be considered: weightings of the stock and its corresponding sector in the benchmark, correlations between the performance of the stocks in the universe, and trading costs. The Fund may purchase foreign securities and securities issued in connection with reorganizations and other special situations.

The overall goal is to build a portfolio of stocks that generate a favorable long-term total return, while also managing the relative risk of the Fund versus its benchmark index. The Fund may also purchase and sell futures, options, 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 the Fund will perform as intended. The markets or the prices of individual securities may be affected by factors not taken into account in Advisors’ analysis.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

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 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, Retail and Class W classes over the applicable one-year, five-year, ten-year and since-inception periods ended December 31, 2023, 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.

TIAA-CREF Quant Small-Cap Equity Fund | Market Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· 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. Such conditions may add significantly to the risk of volatility in the net asset value (“NAV”) of the Fund’s shares and adversely affect the Fund and its investments. 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.

TIAA-CREF Quant Small-Cap Equity Fund | Issuer Risk (often called Financial Risk)  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· Issuer Risk (often called Financial Risk)—The risk that an issuer’s earnings prospects, credit rating 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.

TIAA-CREF Quant Small-Cap Equity Fund | Small-Cap Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· 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.

TIAA-CREF Quant Small-Cap Equity Fund | Mid-Cap Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· 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.
TIAA-CREF Quant Small-Cap Equity Fund | Active Management Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· 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 and may not produce expected returns.
TIAA-CREF Quant Small-Cap Equity Fund | Quantitative Analysis Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· 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.
TIAA-CREF Quant Small-Cap Equity Fund | Foreign Investment Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· 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 as well as armed conflicts 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 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. Changes in the value of foreign currencies may make the return on an investment increase or decrease, unrelated to the quality or performance of the investment itself. The imposition of sanctions, exchange controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) and other restrictions by the United States or other governments may also negatively impact the Fund’s investments. Economic sanctions and other similar governmental actions or developments could, among other things, effectively

restrict or eliminate the Fund’s ability to purchase or sell certain foreign securities or groups of foreign securities, and/or thus may make the Fund’s investments in such securities less liquid (or illiquid) or more difficult to value. The type and severity of sanctions and other measures that may be imposed could vary broadly in scope, and their impact is impossible to predict.
TIAA-CREF Quant Small-Cap Equity Fund | Special Situation Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· Special Situation Risk—Stocks of companies involved in acquisitions, consolidations, tender offers or exchanges, takeovers, reorganizations, mergers and other special situations can involve the risk that such situations may not materialize or may develop in unexpected ways. Consequently, those stocks can involve more risk than ordinary securities.
TIAA-CREF Quant Small-Cap Equity Fund | Illiquid Investments Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· Illiquid Investments Risk—The risk that illiquid investments may be difficult to sell for the value at which they are carried, if at all, or at any price within the desired time frame.

TIAA-CREF Quant Small-Cap Equity Fund | Derivatives Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· Derivatives Risk—The risks associated with investing in derivatives and other similar instruments (referred to collectively as “derivatives”) may be different and greater than the risks associated with directly investing in the underlying securities and other instruments, and include leverage risk, market risk, counterparty risk, liquidity risk, operational risk and legal risk. The Fund may use more complex derivatives that might be particularly susceptible to liquidity, credit and counterparty risk. When investing in derivatives, the Fund may lose more than the principal amount invested.

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) 0.53% of average daily net assets for Institutional Class shares; (ii) 0.68% of average daily net assets for Advisor Class shares; (iii) 0.68% of average daily net assets for Premier Class shares; (iv) 0.78% of average daily net assets for Retirement Class shares; (v) 0.88% of average daily net assets for Retail Class shares; and (vi) 0.53% of average daily net assets for Class W shares of the Fund. These expense reimbursement arrangements will continue through at least February 28, 2025, unless changed with approval of the Board of Trustees.

The performance shown for the Advisor Class and Class W that is prior to their respective inception dates 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 and Class W. If these actual expenses had been reflected, the performance of these two classes shown for these periods would have been different because the Advisor Class and Class W have different expenses than the Institutional Class.

Teachers Advisors, LLC has contractually agreed to waive and/or reimburse Class W’s Management fees and Other expenses (excluding interest, taxes, brokerage commissions or other transactional expenses, Acquired fund fees and expenses, Trustee expenses and extraordinary expenses) in their entirety. Teachers Advisors, LLC expects these waiver and/or reimbursement arrangements to remain in effect indefinitely, unless changed or terminated with approval of the Board of Trustees.
