Objective, Primary [Text Block] oef_ObjectivePrimaryTextBlock

The Fund seeks a favorable long-term total return, mainly through capital appreciation, by investing primarily in a portfolio of equity securities of large domestic value companies based on a market index.

Expense Narrative [Text Block] oef_ExpenseNarrativeTextBlock

The following tables describe 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, when buying or selling shares of the Fund, which are not reflected in the tables and examples below.
Shareholder Fees Caption [Optional Text] oef_ShareholderFeesCaption SHAREHOLDER FEES (fees paid directly from your investment)
Operating Expenses Caption [Optional Text] oef_OperatingExpensesCaption ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment)
Portfolio Turnover [Heading] oef_PortfolioTurnoverHeading Portfolio turnover
Portfolio Turnover [Text Block] oef_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, as applicable, 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, 2025, the Fund’s portfolio turnover rate was 31% of the average value of its portfolio.

Expense Example [Heading] oef_ExpenseExampleHeading Example
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

Under normal circumstances, the Fund invests at least 80% of its assets in securities of its benchmark index, the Russell 1000® Value Index. The Russell 1000 Value Index is a subset of the Russell 1000 Index, which represents the

performance of the large-cap value segment of the U.S. equity universe. It includes those Russell 1000 Index companies with lower relative price-to-book ratios and lower expected growth values. 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 its sub-adviser, Nuveen Asset Management, LLC (“Nuveen Asset Management”), has 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 the returns of the Russell 1000 Value 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 Nuveen Asset Management will attempt to build a portfolio that generally matches the market weighted investment characteristics of the Fund’s benchmark index.

The Fund is classified as a diversified investment company, as defined under the Investment Company Act of 1940, as amended (the “1940 Act”). However, the Fund may become non-diversified under the 1940 Act without the approval of Fund shareholders solely as a result of a change in relative market capitalization or index weighting of one or more constituents of its benchmark index, the Russell 1000 Value Index, which the Fund seeks to track.

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, before taxes, 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 R6, Class I and the Retirement Class over the applicable one-year, five-year, ten-year and since-inception periods ended December 31, 2025, and how those returns compare to those of the Fund’s broad-based securities market index and benchmark index. For periods prior to August 1, 2026, Teachers Advisors, LLC (“Advisors”) served as investment adviser to the Fund. Performance information is not included for Class W as it is not currently operational. After-tax performance is shown only for Class R6 shares, and after-tax returns for the other classes of shares will vary from the after-tax returns presented for Class R6 shares.

The returns shown below reflect previous agreements by Advisors, the Fund’s prior investment adviser, 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 broad-based securities market index and benchmark index listed below are unmanaged, and you cannot invest directly in an index. The returns for the broad-based securities market index and benchmark index reflect no deduction for fees, expenses or taxes.

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:

Nuveen Large Cap Value Index Fund | Market Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· Market Risk—The risk that market prices of portfolio investments held by the Fund may fluctuate rapidly or unpredictably due to a variety of factors, including responses to government actions or interventions, or 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. The Fund currently invests a significant portion of its assets in companies in the financials sector, although this may change over time.

Risk [Text Block] oef_RiskTextBlock

· Index 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.

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 Large Cap Value Index Fund | Style Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· Style Risk—The risk that use of a particular investing style (such as growth or value investing) may fall out of favor in the marketplace for various periods of time and result in underperformance relative to the broader market sector or significant declines in the value of the Fund’s portfolio investments.

Nuveen Large Cap Value Index Fund | Risks of Value Investing  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· Risks of Value Investing—Securities believed to be undervalued are subject to the risks that the issuer’s potential business prospects are not realized, its potential value is never recognized by the market or the securities were appropriately priced when acquired. As a result, value stocks can be overpriced when acquired and may not perform as anticipated.
Nuveen Large Cap Value Index Fund | Large-Cap Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· 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.

Nuveen Large Cap Value Index Fund | Non-Diversification Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· Non-Diversification Risk—While the Fund is considered to be a diversified investment company under the 1940 Act, the Fund may become non-diversified under the 1940 Act without Fund shareholder approval when necessary to continue to track its benchmark index. Non-diversified status means that the Fund can invest a greater percentage of its assets in the securities of a single issuer than a diversified fund. Investing in a non-diversified fund involves greater risk than investing in a diversified fund because a loss in value of a particular investment may have a greater effect on the fund’s return since that investment may represent a larger portion of the fund’s total portfolio assets.
