Expense Example Narrative [Text Block] oef_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] oef_StrategyHeading Principal investment strategies
Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock

The Fund is a “government money market fund,” as defined in the applicable rules governing money market funds, and as such invests at least 99.5% of its total assets in cash, U.S. Government securities and/or repurchase agreements that are collateralized fully by cash or U.S. Government securities. These investments include (1) securities issued by, or whose principal and interest are guaranteed by, the U.S. Government or one of its agencies or instrumentalities and (2) repurchase agreements involving securities issued or guaranteed by the U.S. Government or one of its agencies or instrumentalities. Short-term, U.S. Government securities generally pay interest that is among the lowest for income-paying securities. Because of this, the yield on the Fund will likely be lower than the yields on funds that invest in longer-term or lower-quality securities. The

Fund’s investments may include securities having a variable or floating interest rate.

Generally, the Fund seeks to maintain a share value of $1.00 per share. The Fund’s investments will be made in accordance with the applicable rules governing the quality, maturity and diversification of securities and other instruments held by money market funds. The Fund maintains a dollar-weighted average maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less, and invests in debt obligations with a remaining maturity of 397 days or less.

Teachers Advisors, LLC (“Advisors”) limits the Fund’s investments to U.S. Government securities or securities that present minimal credit risks to the Fund and are of eligible quality.

A government money market fund is not required to impose liquidity fees, and the Fund does not currently intend to impose such fees. However, the Fund’s Board of Trustees of the Trust (“Board of Trustees”) could elect to subject the Fund to such fees in the future.

The above list of investments is not exclusive and the Fund may make other investments consistent with its investment objective and policies.
Bar Chart and Performance Table [Heading] oef_BarChartAndPerformanceTableHeading Past performance
Performance Narrative [Text Block] oef_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 Class R6 of the Fund in each full calendar year for the last ten years. Because the expenses vary across share classes, the performance of Class R6 may vary from the other share classes. Below the bar chart are the best and worst returns of Class R6 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 Class A, Class I, Premier Class, Class R6 and Retirement Class over the applicable one-year, five-year, ten-year and since-inception periods ended December 31, 2024, and how those returns compare to those of the Fund’s peer group average.

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. As of October 14, 2016, certain changes were made to the Fund’s investment strategies. Performance information prior to this date reflects the Fund’s investment strategies before this date. As a result, the Fund’s performance after October 14, 2016 may differ materially from the performance information shown below for the period prior to October 14, 2016. Past performance of the Fund is not necessarily an indication of how it will perform in the future. The peer group average listed below is unmanaged, and you cannot invest directly in the peer group average.

Principal investment risks

You could lose money by investing in this Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Fund is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund’s sponsor is not required to reimburse the Fund for losses, and you should not expect that the sponsor will provide financial support to the Fund at any time, including during periods of market stress. An investment in the Fund, due to the nature of the Fund’s portfolio holdings, typically is subject to the following principal investment risks:
Nuveen Money Market Fund | Risk Lose Money [Member]  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock You could lose money by investing in this Fund.
Nuveen Money Market Fund | Current Income Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· Current Income Risk—The risk that the income the Fund receives may fall as a result of a decline in interest rates. In a low or negative interest rate environment, the Fund may not be able to achieve a positive or zero yield or maintain a stable net asset value (“NAV”) of $1.00 per share.
Nuveen Money Market Fund | Issuer Risk (often called Financial Risk)  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_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.

Nuveen Money Market Fund | Credit Risk (a type of Issuer Risk)  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· Credit Risk (a type of Issuer Risk)—The risk that the issuer of fixed-income investments may not be able or willing, or may be perceived (whether by market participants, rating agencies, pricing services or otherwise) as not able or willing, to meet interest or principal payments when the payments become due. Actual or perceived changes in economic, social, public health, financial or political conditions in general or that affect a particular type of investment, issuer, guarantor or counterparty can reduce the ability of the

party to meet its obligations, which can affect the credit quality, liquidity and/or value of an investment.
Nuveen Money Market Fund | Market Volatility, Liquidity and Valuation Risk (types of Market Risk)  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· 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 its investments and that the Fund may not be able to purchase or sell an investment at an attractive price, if at all.
Nuveen Money Market Fund | Income Volatility Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· Income Volatility Risk—The risk that the level of current income from a portfolio of fixed-income investments may decline in certain interest rate environments.
Nuveen Money Market Fund | Interest Rate Risk (a type of Market Risk)  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· Interest Rate Risk (a type of Market Risk)—The risk that changes in interest rates can adversely affect the value or liquidity of, and income generated by, fixed-income investments. This risk is heightened to the extent the Fund invests in longer duration fixed-income investments and during periods when prevailing interest rates are changing. There is a risk that interest rates across the financial system may change, possibly significantly and/or rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, making it more difficult for the Fund to sell fixed-income investments. When interest rates change, the values of longer duration fixed-income securities usually change more than the values of shorter duration fixed-income securities. Conversely, fixed-income securities with shorter durations or maturities will be less volatile but may provide lower returns than fixed-income securities with longer durations or maturities. Other factors that may affect the value of debt securities include, but are not limited to, economic, political, public health, and other crises and responses by governments and companies to such crises.

Nuveen Money Market Fund | U.S. Government Securities Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· U.S. Government Securities Risk—Securities issued by the U.S. Government or one of its agencies or instrumentalities may receive varying levels of support from the U.S. Government, which could affect the Fund’s ability to recover should they default. To the extent the Fund invests significantly in securities issued or guaranteed by the U.S. Government or its agencies or instrumentalities, any market movements, regulatory changes or changes in political or economic conditions that affect the securities of the U.S. Government or its agencies or instrumentalities in which the Fund invests may have a significant impact on the Fund’s performance.
Nuveen Money Market Fund | Floating and Variable Rate Securities Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· Floating and Variable Rate Securities Risk—Floating and variable rate securities provide for a periodic adjustment in the interest rate paid on the securities. The rate adjustment intervals may be regular and range from daily up to annually, or may be based on an event, such as a change in the prime rate. Floating and variable rate securities may be subject to greater liquidity risk than other debt securities, meaning that there may be limitations on the Fund’s ability to sell the securities at any given time. Such securities also may lose value.
Nuveen Money Market Fund | Active Management Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· Active Management Risk—The risk that Advisors’ strategy, investment selection or trading execution may cause the Fund to underperform relative to the peer group average or mutual funds with similar investment objectives and/or strategies and may not produce the desired results or expected returns.

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) 0.50% of average daily net assets for Class A shares; (ii) 0.30% of average daily net assets for Class I shares; (iii) 0.30% of average daily net assets for Premier Class shares; (iv) 0.15% of average daily net assets for Class R6 shares; (v) 0.40% of average daily net assets for Retirement Class shares; and (vi) 0.15% of average daily net assets for Class W shares of the Fund. These expense reimbursement arrangements will continue through at least July 31, 2026, unless changed with approval of the Board of Trustees.

Part or all of the Rule 12b-1 distribution fee of Class A and Premier Classes and the service fee of the Retirement Class were being voluntarily waived in order to keep the yield of these classes at a minimum of zero. These waivers are voluntary and may be terminated at any time. Advisors is also contractually reimbursing certain expenses through at least July 31, 2026, unless changed with the approval of the Board of Trustees. Without these waivers and reimbursements, total returns would have been lower and expenses would have been higher.
