Objective [Heading]	rr_ObjectiveHeading	Investment Objective
Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The investment objective of the Fund is to provide investors with long-term capital appreciation.
Expense [Heading]	rr_ExpenseHeading	Fees and Expenses of the Fund
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund or in other Nuveen Mutual Funds. More information about these and other discounts, as well as eligibility requirements for each share class, is available from your financial advisor and in “What Share Classes We Offer” on page 31 of the Fund’s prospectus, “How to Reduce Your Sales Charge” on page 33 of the prospectus and “Purchase and Redemption of Fund Shares” on page S-64 of the Fund’s statement of additional information.

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 most recent fiscal year, the Fund’s portfolio turnover rate was 16% of the average value of its portfolio.

Expenses Deferred Charges [Text Block]	rr_ExpensesDeferredChargesTextBlock	The contingent deferred sales charge on Class C shares applies only to redemptions within 12 months of purchase.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	The following example is intended to help you compare the cost of investing in 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 either redeem or do not redeem your shares at the end of a period. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example, No Redemption, By Year, Caption [Text]	rr_ExpenseExampleNoRedemptionByYearCaption	No Redemption
Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in equity securities of companies with market capitalizations at the time of investment comparable to companies in the Russell 1000® Value Index. As of September 30, 2013, the market cap range for the Russell 1000® Value Index was $888 million to $433.1 billion. The Fund will not be forced to sell a stock because it has exceeded or fallen below the current market capitalization range. The Fund's sub-adviser seeks to identify under-valued companies with a catalyst to unlock value or improve profitability. The Fund's sub-adviser maintains a long-term investment view and a focus on securities it believes can appreciate over an extended time, regardless of interim fluctuations. The Fund's sub-adviser will sell securities or reduce positions if it feels that the company no longer possesses favorable risk/reward characteristics, attractive valuations or catalysts. The Fund invests primarily in U.S. equity securities, but it may invest up to 35% of its net assets in non-U.S. equity securities, including up to 10% of its net assets in equity securities of companies located in emerging market countries.
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The value of your investment in this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund, listed alphabetically, include: Currency Risk—Changes in currency exchange rates will affect the value of non-U.S. dollar denominated securities, interest earned from such securities, gains and losses realized on the sale of such securities, and derivative transactions tied to such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund's portfolio. Equity Security Risk—Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular company, industry, or sector of the market. Large Cap Stock Risk—Because it invests primarily in large capitalization stocks, the Fund may underperform funds that invest primarily in stocks of smaller capitalization companies during periods when the stocks of such companies are in favor. Non-U.S./Emerging Markets Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad and different legal, regulatory and tax environments. These additional risks may be heightened for securities of issuers located in, or with significant operations in, emerging market countries. Value Stock Risk—The intrinsic value of a stock with value characteristics may not be fully recognized by the market for a long time or a stock judged to be undervalued may actually be appropriately priced at a low level.
Risk Lose Money [Text]	rr_RiskLoseMoney	The value of your investment in this Fund will change daily. You could lose money by investing in the Fund.
Risk Not Insured Depository Institution [Text]	rr_RiskNotInsuredDepositoryInstitution	An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Table One Class of after Tax Shown [Text]	rr_PerformanceTableOneClassOfAfterTaxShown	After-tax returns are shown for Class A shares only; after-tax returns for other share classes will vary.
Performance Table Narrative	rr_PerformanceTableNarrativeTextBlock	The table below shows the variability of the Fund’s average annual returns and how they compare over the time periods indicated with those of a broad measure of market performance and an index of funds with similar investment objectives. Class R3 shares commenced operations on September 29, 2009. The 5 years and since inception returns for Class R3 shares shown below reflect Class I performance prior to September 29, 2009 adjusted for the difference in fees between the classes. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown for Class A shares only; after-tax returns for other share classes will vary. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as IRAs or employer-sponsored retirement plans. Both the bar chart and the table assume that all distributions have been reinvested. Performance reflects fee waivers, if any, in effect during the periods presented. If any such waivers were not in place, returns would be reduced.

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 most recent fiscal year, the Fund’s portfolio turnover rate was 16% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in equity securities of companies with market capitalizations at the time of investment comparable to companies in the Russell 1000^® Value Index. As of September 30, 2013, the market cap range for the Russell 1000^® Value Index was $888 million to $433.1 billion. The Fund will not be forced to sell a stock because it has exceeded or fallen below the current market capitalization range. The Fund's sub-adviser seeks to identify under-valued companies with a catalyst to unlock value or improve profitability. The Fund's sub-adviser maintains a long-term investment view and a focus on securities it believes can appreciate over an extended time, regardless of interim fluctuations. The Fund's sub-adviser will sell securities or reduce positions if it feels that the company no longer possesses favorable risk/reward characteristics, attractive valuations or catalysts. The Fund invests primarily in U.S. equity securities, but it may invest up to 35% of its net assets in non-U.S. equity securities, including up to 10% of its net assets in equity securities of companies located in emerging market countries.

Principal Risks

The value of your investment in this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund, listed alphabetically, include:

Currency Risk—Changes in currency exchange rates will affect the value of non-U.S. dollar denominated securities, interest earned from such securities, gains and losses realized on the sale of such securities, and derivative transactions tied to such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund's portfolio.

Equity Security Risk—Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular company, industry, or sector of the market.

Large Cap Stock Risk—Because it invests primarily in large capitalization stocks, the Fund may underperform funds that invest primarily in stocks of smaller capitalization companies during periods when the stocks of such companies are in favor.

Non-U.S./Emerging Markets Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad and different legal, regulatory and tax environments. These additional risks may be heightened for securities of issuers located in, or with significant operations in, emerging market countries.

Value Stock Risk—The intrinsic value of a stock with value characteristics may not be fully recognized by the market for a long time or a stock judged to be undervalued may actually be appropriately priced at a low level.

Fund Performance

The following bar chart and table provide some indication of the potential risks of investing in the Fund. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at www.nuveen.com/performance or by calling (800) 257-8787.

The bar chart below shows the variability of the Fund’s performance from year to year for Class A shares. The performance of the other share classes will differ due to their different expense structures. The bar chart and highest/lowest quarterly returns that follow do not reflect sales charges, and if these charges were reflected, the returns would be less than those shown.

Class A Annual Total Return

During the six-year period ended December 31, 2012, the Fund’s highest and lowest quarterly returns were 19.12% and -19.14%, respectively, for the quarters ended September 30, 2009 and December 31, 2008.

The table below shows the variability of the Fund’s average annual returns and how they compare over the time periods indicated with those of a broad measure of market performance and an index of funds with similar investment objectives. Class R3 shares commenced operations on September 29, 2009. The 5 years and since inception returns for Class R3 shares shown below reflect Class I performance prior to September 29, 2009 adjusted for the difference in fees between the classes. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown for Class A shares only; after-tax returns for other share classes will vary. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as IRAs or employer-sponsored retirement plans.

Both the bar chart and the table assume that all distributions have been reinvested. Performance reflects fee waivers, if any, in effect during the periods presented. If any such waivers were not in place, returns would be reduced.

Example

The following example is intended to help you compare the cost of investing in 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 either redeem or do not redeem your shares at the end of a period. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are at the lesser of total annual fund operating expenses or the applicable expense limitation. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

5 Years	1,257	1,114	859	599
10 Years	2,074	2,400	1,877	1,327

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 most recent fiscal year, the Fund’s portfolio turnover rate was 49% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in equity securities of companies with market capitalizations at the time of investment comparable to companies in the Russell 2500^® Value Index. As of September 30, 2013, the market cap range for the Russell 2500^® Value Index was $42 million to $11.5 billion. The Fund will not be forced to sell a stock because it has exceeded or fallen below the current market capitalization range. The Fund’s sub-adviser seeks to identify under-valued companies with a catalyst to unlock value or improve profitability. The Fund’s sub-adviser maintains a long-term investment view and a focus on securities it believes can appreciate over an extended time, regardless of interim fluctuations. The Fund’s sub-adviser will sell securities or reduce positions if it feels that the company no longer possesses favorable risk/reward characteristics, attractive valuations or catalysts. The Fund invests primarily in U.S. equity securities, but it may invest up to 35% of its net assets in non-U.S. equity securities, including up to 10% of its net assets in equity securities of companies located in emerging market countries.

Principal Risks

The value of your investment in this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund, listed alphabetically, include:

Equity Security Risk—Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular company, industry, or sector of the market.

Non-U.S./Emerging Markets Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad and different legal, regulatory and tax environments. These additional risks may be heightened for securities of issuers located in, or with significant operations in, emerging market countries.

Smaller Company Risk—Small-cap stocks involve substantial risk. Prices of small-cap stocks may be subject to more abrupt or erratic movements, and to wider fluctuations, than stock prices of larger, more established companies or the market averages in general. It may be difficult to sell small-cap stocks at the desired time and price. While mid-cap stocks may be slightly less volatile than small-cap stocks, they still involve similar risks.

Value Stock Risk—The intrinsic value of a stock with value characteristics may not be fully recognized by the market for a long time or a stock judged to be undervalued may actually be appropriately priced at a low level.

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in equity securities of large-capitalization companies. Large capitalization companies are defined as companies that have market capitalizations at the time of purchase within the market capitalization range of the companies in the Russell 1000 Index immediately after its most recent reconstitution prior to such purchase. It is expected that reconstitution of the index will occur each year at the end of June. Immediately after the most recent reconstitution, the range was $488.0 million to $397.7 billion. Substantially all of the equity securities in which the Fund invests will be included in the Fund's benchmark index, the Russell 1000 Value Index, at the time of purchase. The Fund's sub-adviser will select securities using an investment process that combines quantitative techniques, fundamental analysis and risk management. Securities generally are added to the portfolio based both on security rankings provided by multi-factor quantitative models and on fundamental analysis of the securities. In addition, the sub-adviser will utilize risk management techniques to establish constraints on the amounts invested in individual securities and sectors. The Fund's sub-adviser will generally sell a security if its model ranking declines or research reveals a deterioration of the company's fundamentals. The Fund may enter into stock index futures contracts to manage cash flows into and out of the Fund.

Futures Contract Risk—The use of futures contracts involves additional risks and transaction costs, which could leave the Fund in a worse position than if it had not used these instruments. Futures contracts may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in futures contracts could have a large impact on performance. Investment Strategy Risk—Proprietary and third party data and systems are utilized to support decision making for the Fund. Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance. Furthermore, there can be no assurance that the quantitative models used in managing the Fund will perform as anticipated or enable the Fund to achieve its objective. Large Cap Stock Risk—Because it invests primarily in large capitalization stocks, the Fund may underperform funds that invest primarily in stocks of smaller capitalization companies during periods when the stocks of such companies are in favor. Value Stock Risk—The intrinsic value of a stock with value characteristics may not be fully recognized by the market for a long time or a stock judged to be undervalued may actually be appropriately priced at a low level.

Example

The following example is intended to help you compare the cost of investing in 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 either redeem or do not redeem your shares at the end of a period. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Redemption

1 Year	707	215	171	112	114
3 Years	987	664	530	350	356
5 Years	1,287	1,139	913	606	617
10 Years	2,137	2,452	1,987	1,340	1,363

No Redemption

3 Years	987	664	530	350	356
5 Years	1,287	1,139	913	606	617
10 Years	2,137	2,452	1,987	1,340	1,363

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 most recent fiscal year, the Fund’s portfolio turnover rate was 41% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in equity securities of companies with market capitalizations at the time of investment comparable to companies in either the Russell 2000^® Value Index or the Standard & Poor’s SmallCap 600 Index. As of September 30, 2013, the market cap range for the Russell 2000^® Value Index was $42 million to $4.4 billion and the market cap range for the Standard & Poor’s SmallCap 600 Index was $100 million to $5.0 billion. The Fund will not be forced to sell a stock because it has exceeded or fallen below the current market capitalization range. The Fund’s sub-adviser seeks to identify under-valued companies with a catalyst to unlock value or improve profitability. The Fund’s sub-adviser maintains a long-term investment view and a focus on securities it believes can appreciate over an extended time, regardless of interim fluctuations. The Fund’s sub-adviser will sell securities or reduce positions if it feels that the company no longer possesses favorable risk/reward characteristics, attractive valuations or catalysts. The Fund invests primarily in U.S. equity securities, but it may invest up to 35% of its net assets in non-U.S. equity securities, including up to 10% of its net assets in equity securities of companies located in emerging market countries.

Principal Risks

The value of your investment in this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund, listed alphabetically, include:

Currency Risk—Changes in currency exchange rates will affect the value of non-U.S. dollar denominated securities, interest earned from such securities, gains and losses realized on the sale of such securities, and derivative transactions tied to such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund’s portfolio.

Equity Security Risk—Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular company, industry, or sector of the market.

Non-U.S./Emerging Markets Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad and different legal, regulatory and tax environments. These additional risks may be heightened for securities of issuers located in, or with significant operations in, emerging market countries.

Small-Cap Stock Risk—Small-cap stocks may involve greater risks than large-cap stocks. Prices of small-cap stocks may be subject to more abrupt or erratic movements, and to wider fluctuations, than stock prices of larger, more established companies or the market averages in general. It may be difficult to sell small-cap stocks at the desired time and price.

Value Stock Risk—The intrinsic value of a stock with value characteristics may not be fully recognized by the market for a long time or a stock judged to be undervalued may actually be appropriately priced at a low level.

Fund Performance

The following bar chart and table provide some indication of the potential risks of investing in the Fund. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at www.nuveen.com/performance or by calling (800) 257-8787.

The bar chart below shows the variability of the Fund’s performance from year to year for Class A shares. The performance of the other share classes will differ due to their different expense structures. The bar chart and highest/lowest quarterly returns that follow do not reflect sales charges, and if these charges were reflected, the returns would be less than those shown.

Class A Annual Total Return

During the eight-year period ended December 31, 2012, the Fund’s highest and lowest quarterly returns were 25.53% and -35.69%, respectively, for the quarters ended September 30, 2009 and December 31, 2008.

The table below shows the variability of the Fund’s average annual returns and how they compare over the time periods indicated with those of a broad measure of market performance and an index of funds with similar investment objectives. Class R3 shares commenced operations on September 29, 2009. The 5 years and since inception returns for Class R3 shares shown below reflect Class I performance prior to September 29, 2009 adjusted for the difference in fees between the classes. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown for Class A shares only; after-tax returns for other share classes will vary. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as IRAs or employer-sponsored retirement plans.

Both the bar chart and the table assume that all distributions have been reinvested. Performance reflects fee waivers, if any, in effect during the periods presented. If any such waivers were not in place, returns would be reduced.

Performance is not shown for Class R6 shares, which have not been offered for a full calendar year.

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 most recent fiscal year, the Fund’s portfolio turnover rate was 84% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests primarily in equity securities of companies with varying market capitalizations, which may include small-, mid- and large-capitalization companies. The Fund's sub-adviser opportunistically seeks to identify under-valued companies considering absolute valuation and security pricing in the context of industry and market conditions. The sub-adviser's disciplined, value-oriented investment strategy focuses on rigorous financial statements and valuation analysis, qualitative factors and portfolio downside protection. The Fund invests primarily in U.S. equity securities, but it may invest up to 35% of its net assets in non-U.S. equity securities, including up to 15% of its net assets in equity securities of companies located in emerging market countries.

These additional risks may be heightened for securities of issuers located in, or with significant operations in, emerging market countries.

Smaller Company Risk—Small-cap stocks involve substantial risk. Prices of small-cap stocks may be subject to more abrupt or erratic movements, and to wider fluctuations, than stock prices of larger, more established companies or the market averages in general. It may be difficult to sell small-cap stocks at the desired time and price. While mid-cap stocks may be slightly less volatile than small-cap stocks, they still involve similar risks.

Value Stock Risk—The intrinsic value of a stock with value characteristics may not be fully recognized by the market for a long time or a stock judged to be undervalued may actually be appropriately priced at a low level.

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 most recent fiscal year, the Fund’s portfolio turnover rate was 176% of the average value of its portfolio.

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then either redeem or do not redeem your shares at the end of a period. The example also assumes that your investment has a 5% return each year, that the Fund’s operating expenses remain the same, and the contractual fee waivers currently in place are not renewed beyond October 31, 2014. 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 market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in bonds from issuers located around the world. The bonds in which the Fund may invest may be of any maturity and include: debt obligations of foreign governments; domestic and foreign corporate debt obligations, including obligations issued by special-purpose entities that are backed by corporate debt obligations; U.S. government securities (securities issued or guaranteed by the U.S. government or its agencies or instrumentalities); residential and commercial mortgage-backed securities; and asset-backed securities. Under normal market conditions, the Fund invests at least 40% of its net assets in non-U.S. issuers and is invested in issuers located in at least three countries (including the United States). The Fund may invest in debt obligations issued by governmental and corporate issuers located in emerging markets countries. The Fund invests in securities that are U.S. dollar-denominated and in securities that are denominated in foreign currencies. As described in more detail below, the Fund may utilize various currency-related derivatives in an effort to enhance the Fund's total return or to manage risk. Up to 30% of the Fund's net assets may be invested in securities rated lower than investment grade or in unrated securities of comparable quality as determined by the Fund's sub-adviser (such securities commonly referred to as "high yield" or "junk bonds"). If the rating of a security is reduced or the credit quality of an unrated security declines after purchase, the Fund is not required to sell the security, but may consider doing so. The Fund may utilize the following derivatives: options; futures contracts; options on futures contracts; interest rate caps, collars, and floors; foreign currency contracts; options on foreign currencies; swap agreements, including swap agreements on interest rates, currency rates, security indexes and specific securities, and credit default swap agreements; and options on the foregoing types of swap agreements. The Fund may enter into standardized derivatives contracts traded on domestic or foreign securities exchanges, boards of trade, or similar entities, and non-standardized derivatives contracts traded in the over-the-counter market. The Fund may use these derivatives in an attempt to manage market risk, currency risk, credit risk and yield curve risk, to manage the effective maturity or duration of securities in the Fund's portfolio or for speculative purposes in an effort to enhance returns. The Fund may also use derivatives to gain exposure to non-dollar denominated securities markets to the extent it does not do so through direct investments. The use of a derivative is speculative if the Fund is primarily seeking to enhance returns, rather than offset the risk of other positions. The Fund may not use any derivative to gain exposure to a security or type of security that it would be prohibited by its investment restrictions from purchasing directly. The Fund's sub-adviser uses a team-based and research-driven investment process for the Fund. The portfolio management team relies on both top-down and bottom-up research to identify attractive investment opportunities and to manage the Fund's risk.
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The value of your investment in this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund, listed alphabetically, include: Call Risk—If an issuer calls higher-yielding debt instruments held by the Fund, performance could be adversely impacted. Credit Risk—Credit risk is the risk that an issuer of a debt security may be unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer's ability or willingness to make such payments. Currency Risk—Changes in currency exchange rates will affect the value of non-U.S. dollar denominated securities, interest earned from such securities, gains and losses realized on the sale of such securities, and derivative transactions tied to such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund's portfolio. Derivatives Risk—The use of options; futures contracts; options on futures contracts; interest rate caps, collars, and floors; foreign currency contracts; options on foreign currencies; swap agreements, including swap agreements on interest rates, currency rates, security indexes and specific securities, and credit default swap agreements; and options on the foregoing types of swap agreements may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives can result in losses that greatly exceed the original investment. Derivatives can be highly volatile, illiquid and difficult to value. A derivative transaction also involves the risk that a loss may be sustained as a result of the failure of the counterparty to the contract to make required payments. High Yield Securities Risk—High yield securities, which are rated below investment grade and commonly referred to as "junk" bonds, are high risk investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid and have more volatile prices than investment grade securities. Income Risk—The Fund's income could decline during periods of falling interest rates. Interest Rate Risk—Interest rate risk is the risk that the value of the Fund's portfolio will decline because of rising interest rates. When interest rates change, the values of longer-duration debt securities usually change more than the values of shorter-duration debt securities. Mortgage- and Asset-Backed Securities Risk—These securities generally can be prepaid at any time. Prepayments that occur either more quickly or more slowly than expected can adversely impact the value of such securities. They are also subject to extension risk, which is the risk that rising interest rates could cause mortgages or other obligations underlying the securities to be prepaid more slowly than expected, thereby lengthening the duration of such securities, increasing their sensitivity to interest rate changes and causing their prices to decline. A mortgage-backed security may be negatively affected by the quality of the mortgages underlying such security, the credit quality of its issuer or guarantor, and the nature and structure of its credit support. Non-U.S./Emerging Markets Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad and different legal, regulatory and tax environments. These additional risks may be heightened for securities of issuers located in, or with significant operations in, emerging market countries.

As of September 30, 2013, the market cap range for the Russell 2500® Value Index was $42 million to $11.5 billion. The Fund will not be forced to sell a stock because it has exceeded or fallen below the current market capitalization range. The Fund’s sub-adviser seeks to identify under-valued companies with a catalyst to unlock value or improve profitability. The Fund’s sub-adviser maintains a long-term investment view and a focus on securities it believes can appreciate over an extended time, regardless of interim fluctuations.

Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The value of your investment in this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund, listed alphabetically, include: Currency Risk—Changes in currency exchange rates will affect the value of non-U.S. dollar denominated securities, interest earned from such securities, gains and losses realized on the sale of such securities, and derivative transactions tied to such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund’s portfolio. Equity Security Risk—Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular company, industry, or sector of the market. Non-U.S./Emerging Markets Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad and different legal, regulatory and tax environments. These additional risks may be heightened for securities of issuers located in, or with significant operations in, emerging market countries. Smaller Company Risk—Small-cap stocks involve substantial risk. Prices of small-cap stocks may be subject to more abrupt or erratic movements, and to wider fluctuations, than stock prices of larger, more established companies or the market averages in general. It may be difficult to sell small-cap stocks at the desired time and price. While mid-cap stocks may be slightly less volatile than small-cap stocks, they still involve similar risks. Value Stock Risk—The intrinsic value of a stock with value characteristics may not be fully recognized by the market for a long time or a stock judged to be undervalued may actually be appropriately priced at a low level.

These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 22% of the average value of its portfolio.

Objective [Heading]	rr_ObjectiveHeading	Investment Objective
Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The investment objective of the Fund is to provide investors with long-term capital appreciation.
Expense [Heading]	rr_ExpenseHeading	Fees and Expenses of the Fund
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund or in other Nuveen Mutual Funds. More information about these and other discounts, as well as eligibility requirements for each share class, is available from your financial advisor and in “What Share Classes We Offer” on page 31 of the Fund’s prospectus, “How to Reduce Your Sales Charge” on page 33 of the prospectus and “Purchase and Redemption of Fund Shares” on page S-64 of the Fund’s statement of additional information.

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 most recent fiscal year, the Fund’s portfolio turnover rate was 84% of the average value of its portfolio.

Expense Example [Heading]	rr_ExpenseExampleHeading	Example
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	The following example is intended to help you compare the cost of investing in 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 either redeem or do not redeem your shares at the end of a period. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Expense Example by, Year, Caption [Text]	rr_ExpenseExampleByYearCaption	Redemption
Expense Example, No Redemption, By Year, Caption [Text]	rr_ExpenseExampleNoRedemptionByYearCaption	No Redemption
Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests primarily in equity securities of companies with varying market capitalizations, which may include small-, mid- and large-capitalization companies. The Fund's sub-adviser opportunistically seeks to identify under-valued companies considering absolute valuation and security pricing in the context of industry and market conditions. The sub-adviser's disciplined, value-oriented investment strategy focuses on rigorous financial statements and valuation analysis, qualitative factors and portfolio downside protection. The Fund invests primarily in U.S. equity securities, but it may invest up to 35% of its net assets in non-U.S. equity securities, including up to 15% of its net assets in equity securities of companies located in emerging market countries.
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The value of your investment in this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund, listed alphabetically, include: Currency Risk—Changes in currency exchange rates will affect the value of non-U.S. dollar denominated securities, interest earned from such securities, gains and losses realized on the sale of such securities, and derivative transactions tied to such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund's portfolio. Equity Security Risk—Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular company, industry, or sector of the market. Non-U.S./Emerging Markets Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad and different legal, regulatory and tax environments. These additional risks may be heightened for securities of issuers located in, or with significant operations in, emerging market countries. Smaller Company Risk—Small-cap stocks involve substantial risk. Prices of small-cap stocks may be subject to more abrupt or erratic movements, and to wider fluctuations, than stock prices of larger, more established companies or the market averages in general. It may be difficult to sell small-cap stocks at the desired time and price. While mid-cap stocks may be slightly less volatile than small-cap stocks, they still involve similar risks. Value Stock Risk—The intrinsic value of a stock with value characteristics may not be fully recognized by the market for a long time or a stock judged to be undervalued may actually be appropriately priced at a low level.
Risk Lose Money [Text]	rr_RiskLoseMoney	The value of your investment in this Fund will change daily. You could lose money by investing in the Fund.
Risk Not Insured Depository Institution [Text]	rr_RiskNotInsuredDepositoryInstitution	An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Fund Performance
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The following bar chart and table provide some indication of the potential risks of investing in the Fund. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at www.nuveen.com/performance or by calling (800) 257-8787.

Bar Chart [Heading]	rr_BarChartHeading	Class A Annual Total Return
Bar Chart Narrative [Text Block]	rr_BarChartNarrativeTextBlock	The bar chart below shows the variability of the Fund’s performance from year to year for Class A shares. The performance of the other share classes will differ due to their different expense structures. The bar chart and highest/lowest quarterly returns that follow do not reflect sales charges, and if these charges were reflected, the returns would be less than those shown.
Bar Chart Does Not Reflect Sales Loads [Text]	rr_BarChartDoesNotReflectSalesLoads	The bar chart and highest/lowest quarterly returns that follow do not reflect sales charges, and if these charges were reflected, the returns would be less than those shown.
Bar Chart Closing [Text Block]	rr_BarChartClosingTextBlock	During the eight-year period ended December 31, 2012, the Fund’s highest and lowest quarterly returns were 22.01% and -16.11%, respectively, for the quarters ended June 30, 2009 and September 30, 2008.
Performance Table Heading	rr_PerformanceTableHeading	Average Annual Total Returns for the Periods Ended December 31, 2012
Performance Table Uses Highest Federal Rate	rr_PerformanceTableUsesHighestFederalRate	All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes.
Performance Table Not Relevant to Tax Deferred	rr_PerformanceTableNotRelevantToTaxDeferred	After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as IRAs or employer-sponsored retirement plans.
Performance Table One Class of after Tax Shown [Text]	rr_PerformanceTableOneClassOfAfterTaxShown	After-tax returns are shown for Class A shares only; after-tax returns for other share classes will vary.
Performance Table Narrative	rr_PerformanceTableNarrativeTextBlock	The table below shows the variability of the Fund’s average annual returns and how they compare over the time periods indicated with those of a broad measure of market performance and an index of funds with similar investment objectives. Class R3 shares commenced operations on August 4, 2008. The 5 years and since inception returns for Class R3 shares shown below reflect Class I performance prior to August 4, 2008 adjusted for the difference in fees between the classes. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown for Class A shares only; after-tax returns for other share classes will vary. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as IRAs or employer-sponsored retirement plans. Both the bar chart and the table assume that all distributions have been reinvested. Performance reflects fee waivers, if any, in effect during the periods presented. If any such waivers were not in place, returns would be reduced.

Investment Objective

The investment objective of the Fund is to provide investors with long-term capital appreciation.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund or in other Nuveen Mutual Funds. More information about these and other discounts, as well as eligibility requirements for each share class, is available from your financial advisor and in “What Share Classes We Offer” on page 10 of the Fund’s prospectus, “How to Reduce Your Sales Charge” on page 12 of the prospectus and “Purchase and Redemption of Fund Shares” on page S-49 of the Fund’s statement of additional information.

Example

The following example is intended to help you compare the cost of investing in 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 either redeem or do not redeem your shares at the end of a period. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

10 Years	1,903	2,038	2,233	1,691	1,120

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 most recent fiscal year, the Fund’s portfolio turnover rate was 153% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in equity securities of large-capitalization companies. Large capitalization companies are defined as companies that have market capitalizations at the time of purchase within the market capitalization range of the companies in the Russell 1000 Index immediately after its most recent reconstitution prior to such purchase. It is expected that reconstitution of the index will occur each year at the end of June. Immediately after the most recent reconstitution, the range was $488.0 million to $397.7 billion. Substantially all of the equity securities in which the Fund invests will be included in the Fund's benchmark index, the Russell 1000 Value Index, at the time of purchase.

The Fund's sub-adviser will select securities using an investment process that combines quantitative techniques, fundamental analysis and risk management. Securities generally are added to the portfolio based both on security rankings provided by multi-factor quantitative models and on fundamental analysis of the securities. In addition, the sub-adviser will utilize risk management techniques to establish constraints on the amounts invested in individual securities and sectors. The Fund's sub-adviser will generally sell a security if its model ranking declines or research reveals a deterioration of the company's fundamentals.

The Fund may enter into stock index futures contracts to manage cash flows into and out of the Fund.

Principal Risks

The value of your investment in this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund, listed alphabetically, include:

Equity Security Risk—Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular company, industry, or sector of the market.

Futures Contract Risk—The use of futures contracts involves additional risks and transaction costs, which could leave the Fund in a worse position than if it had not used these instruments. Futures contracts may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in futures contracts could have a large impact on performance.

Investment Strategy Risk—Proprietary and third party data and systems are utilized to support decision making for the Fund. Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance. Furthermore, there can be no assurance that the quantitative models used in managing the Fund will perform as anticipated or enable the Fund to achieve its objective.

Large Cap Stock Risk—Because it invests primarily in large capitalization stocks, the Fund may underperform funds that invest primarily in stocks of smaller capitalization companies during periods when the stocks of such companies are in favor.

Value Stock Risk—The intrinsic value of a stock with value characteristics may not be fully recognized by the market for a long time or a stock judged to be undervalued may actually be appropriately priced at a low level.

Fund Performance

The following bar chart and table provide some indication of the potential risks of investing in the Fund. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Performance prior to June 24, 2013, reflects the Fund’s performance under the management of multiple sub-advisers using investment strategies that differed significantly from those currently in place. Updated performance information is available at www.nuveen.com/performance or by calling (800) 257-8787.

The bar chart below shows the variability of the Fund’s performance from year to year for Class A shares. The performance of the other share classes will differ due to their different expense structures. The bar chart and highest/lowest quarterly returns that follow do not reflect sales charges, and if these charges were reflected, the returns would be less than those shown.

Class A Annual Total Return

During the ten-year period ended December 31, 2012, the Fund's highest and lowest quarterly returns were 16.94% and -21.89%, respectively, for the quarters ended September 30, 2009 and December 31, 2008.

The table below shows the variability of the Fund’s average annual returns and how they compare over the time periods indicated with those of broad measures of market performance (the Russell 1000^® Value Index is the Fund’s primary benchmark) and an index of funds with similar investment objectives. Class R3 shares commenced operations on August 4, 2008. The 5 and 10 year returns for Class R3 shares shown below reflect Class I performance prior to August 4, 2008 adjusted for the difference in fees between the classes. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown for Class A shares only; after-tax returns for other share classes will vary. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as IRAs or employer-sponsored retirement plans.

Both the bar chart and the table assume that all distributions have been reinvested. Performance reflects fee waivers, if any, in effect during the periods presented. If any such waivers were not in place, returns would be reduced.

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 most recent fiscal year, the Fund’s portfolio turnover rate was 44% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in equity securities. The Fund invests primarily in income producing common stocks, but it may also invest in preferred securities, convertible securities and corporate debt securities. The Fund may also write covered call options on securities in which the Fund holds a long position. The Fund may invest up to 20% of its net assets in fixed-income securities, including up to 10% of its net assets in below investment-grade debt securities, commonly referred to as "high yield," "high risk" or "junk" bonds. The Fund may also invest up to 35% of its net assets in non-U.S. securities, including up to 10% of its net assets in securities of companies located in emerging markets.

Principal Risks

The value of your investment in this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund, listed alphabetically, include:

Call Risk—If an issuer calls higher-yielding debt instruments held by the Fund, performance could be adversely impacted.

Convertible Security Risk—The value of the Fund's convertible securities may decline in response to such factors as rising interest rates and fluctuations in the market price of the common stock underlying the convertible securities.

Covered Call Risk—Covered call risk is the risk that the Fund, as a writer of covered call options, will forgo during an option's life the opportunity to profit from increases in the market value of the security covering the call option.

Credit Risk—Credit risk is the risk that an issuer of a debt security may be unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer's ability or willingness to make such payments.

Currency Risk—Changes in currency exchange rates will affect the value of non-U.S. dollar denominated securities, interest earned from such securities, gains and losses realized on the sale of such securities, and derivative transactions tied to such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund's portfolio.

Derivatives Risk—The use of covered call options involves additional risks and transaction costs which could leave the Fund in a worse position than if it had not used these instruments. Derivatives may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives can result in losses that greatly exceed the original investment. Derivatives can be highly volatile, illiquid and difficult to value. A derivative transaction also involves the risk that a loss may be sustained as a result of the failure of the counterparty to the contract to make required payments.

Equity Security Risk—Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular company, industry, or sector of the market.

High Yield Securities Risk—High yield securities, which are rated below investment grade and commonly referred to as "junk" bonds, are high risk investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid and have more volatile prices than investment grade securities.

Income Risk—The Fund's income could decline during periods of falling interest rates.

Interest Rate Risk—Interest rate risk is the risk that the value of the Fund's portfolio will decline because of rising interest rates. When interest rates change, the values of longer-duration debt securities usually change more than the values of shorter-duration debt securities.

Non-U.S./Emerging Markets Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad and different legal, regulatory and tax environments. These additional risks may be heightened for securities of issuers located in, or with significant operations in, emerging market countries.

Preferred Security Risk—Preferred securities are subordinated to bonds and other debt instruments in a company's capital structure and therefore will be subject to greater credit risk than those debt instruments. In addition, preferred securities are subject to other risks, such as having no or limited voting rights, being subject to special redemption rights, having distributions deferred or skipped, having limited liquidity, changing tax treatments and possibly being in heavily regulated industries.

Smaller Company Risk—Small-cap stocks involve substantial risk. Prices of small-cap stocks may be subject to more abrupt or erratic movements, and to wider fluctuations, than stock prices of larger, more established companies or the market averages in general. It may be difficult to sell small-cap stocks at the desired time and price. While mid-cap stocks may be slightly less volatile than small-cap stocks, they still involve similar risks.

Fund Performance

The following bar chart and table provide some indication of the potential risks of investing in the Fund. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at www.nuveen.com/performance or by calling (800) 257-8787.

The bar chart below shows the variability of the Fund’s performance from year to year for Class A shares. The performance of the other share classes will differ due to their different expense structures. The bar chart and highest/lowest quarterly returns that follow do not reflect sales charges, and if these charges were reflected, the returns would be less than those shown.

Class A Annual Total Return

During the three-year period ended December 31, 2012, the Fund's highest and lowest quarterly returns were 11.96% and -16.52%, respectively, for the quarters ended March 31, 2012 and September 30, 2011.

The table below shows the variability of the Fund’s average annual returns and how they compare over the time periods indicated with those of a broad measure of market performance and an index of funds with similar investment objectives. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown for Class A shares only; after-tax returns for other share classes will vary. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as IRAs or employer-sponsored retirement plans.

Both the bar chart and the table assume that all distributions have been reinvested. Performance reflects fee waivers, if any, in effect during the periods presented. If any such waivers were not in place, returns would be reduced.

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then either redeem or do not redeem your shares at the end of a period. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

10 Years	2,063	2,205	2,390	1,856	1,294

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 most recent fiscal year, the Fund’s portfolio turnover rate was 22% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its net assets in equity securities of companies with large, medium and small capitalizations. The Fund's sub-adviser seeks to identify under-valued companies with a catalyst to unlock value or improve profitability. The Fund's sub-adviser maintains a long-term investment view and a focus on securities it believes can appreciate over an extended time, regardless of interim fluctuations. The Fund's sub-adviser will sell securities or reduce positions if it feels that the company no longer possesses favorable risk/reward characteristics, attractive valuations or catalysts. The Fund invests primarily in U.S. equity securities, but it may invest up to 35% of its net assets in non-U.S. equity securities, including up to 10% of its net assets in equity securities of companies located in emerging market countries.

Principal Risks

The value of your investment in this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund, listed alphabetically, include:

Currency Risk—Changes in currency exchange rates will affect the value of non-U.S. dollar denominated securities, interest earned from such securities, gains and losses realized on the sale of such securities, and derivative transactions tied to such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund's portfolio.

Equity Security Risk—Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular company, industry, or sector of the market.

Non-U.S./Emerging Markets Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad and different legal, regulatory and tax environments. These additional risks may be heightened for securities of issuers located in, or with significant operations in, emerging market countries.

Smaller Company Risk—Small-cap stocks involve substantial risk. Prices of small-cap stocks may be subject to more abrupt or erratic movements, and to wider fluctuations, than stock prices of larger, more established companies or the market averages in general. It may be difficult to sell small-cap stocks at the desired time and price. While mid-cap stocks may be slightly less volatile than small-cap stocks, they still involve similar risks.

Value Stock Risk—The intrinsic value of a stock with value characteristics may not be fully recognized by the market for a long time or a stock judged to be undervalued may actually be appropriately priced at a low level.

Fund Performance

The following bar chart and table provide some indication of the potential risks of investing in the Fund. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at www.nuveen.com/performance or by calling (800) 257-8787.

The bar chart below shows the variability of the Fund’s performance from year to year for Class A shares. The performance of the other share classes will differ due to their different expense structures. The bar chart and highest/lowest quarterly returns that follow do not reflect sales charges, and if these charges were reflected, the returns would be less than those shown.

Class A Annual Total Return

During the ten-year period ended December 31, 2012, the Fund’s highest and lowest quarterly returns were 26.52% and -25.36%, respectively, for the quarters ended June 30, 2003 and December 31, 2008.

The table below shows the variability of the Fund’s average annual returns and how they compare over the time periods indicated with those of broad measures of market performance (the Russell 3000^® Value Index is the Fund’s primary benchmark) and an index of funds with similar investment objectives. Class R3 shares commenced operations on August 4, 2008. The 5 and 10 year returns for Class R3 shares shown below reflect Class I performance prior to August 4, 2008 adjusted for the difference in fees between the classes. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown for Class A shares only; after-tax returns for other share classes will vary. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as IRAs or employer-sponsored retirement plans.

Both the bar chart and the table assume that all distributions have been reinvested. Performance reflects fee waivers, if any, in effect during the periods presented. If any such waivers were not in place, returns would be reduced.

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in equity securities. The Fund invests primarily in income producing common stocks, but it may also invest in preferred securities, convertible securities and corporate debt securities. The Fund may also write covered call options on securities in which the Fund holds a long position. The Fund may invest up to 20% of its net assets in fixed-income securities, including up to 10% of its net assets in below investment-grade debt securities, commonly referred to as "high yield," "high risk" or "junk" bonds. The Fund may also invest up to 35% of its net assets in non-U.S. securities, including up to 10% of its net assets in securities of companies located in emerging markets.
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The value of your investment in this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund, listed alphabetically, include: Call Risk—If an issuer calls higher-yielding debt instruments held by the Fund, performance could be adversely impacted. Convertible Security Risk—The value of the Fund's convertible securities may decline in response to such factors as rising interest rates and fluctuations in the market price of the common stock underlying the convertible securities. Covered Call Risk—Covered call risk is the risk that the Fund, as a writer of covered call options, will forgo during an option's life the opportunity to profit from increases in the market value of the security covering the call option. Credit Risk—Credit risk is the risk that an issuer of a debt security may be unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer's ability or willingness to make such payments. Currency Risk—Changes in currency exchange rates will affect the value of non-U.S. dollar denominated securities, interest earned from such securities, gains and losses realized on the sale of such securities, and derivative transactions tied to such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund's portfolio. Derivatives Risk—The use of covered call options involves additional risks and transaction costs which could leave the Fund in a worse position than if it had not used these instruments. Derivatives may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives can result in losses that greatly exceed the original investment. Derivatives can be highly volatile, illiquid and difficult to value. A derivative transaction also involves the risk that a loss may be sustained as a result of the failure of the counterparty to the contract to make required payments. Equity Security Risk—Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular company, industry, or sector of the market. High Yield Securities Risk—High yield securities, which are rated below investment grade and commonly referred to as "junk" bonds, are high risk investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid and have more volatile prices than investment grade securities. Income Risk—The Fund's income could decline during periods of falling interest rates. Interest Rate Risk—Interest rate risk is the risk that the value of the Fund's portfolio will decline because of rising interest rates. When interest rates change, the values of longer-duration debt securities usually change more than the values of shorter-duration debt securities. Non-U.S./Emerging Markets Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad and different legal, regulatory and tax environments. These additional risks may be heightened for securities of issuers located in, or with significant operations in, emerging market countries. Preferred Security Risk—Preferred securities are subordinated to bonds and other debt instruments in a company's capital structure and therefore will be subject to greater credit risk than those debt instruments. In addition, preferred securities are subject to other risks, such as having no or limited voting rights, being subject to special redemption rights, having distributions deferred or skipped, having limited liquidity, changing tax treatments and possibly being in heavily regulated industries. Smaller Company Risk—Small-cap stocks involve substantial risk. Prices of small-cap stocks may be subject to more abrupt or erratic movements, and to wider fluctuations, than stock prices of larger, more established companies or the market averages in general. It may be difficult to sell small-cap stocks at the desired time and price. While mid-cap stocks may be slightly less volatile than small-cap stocks, they still involve similar risks.

Example

The following example is intended to help you compare the cost of investing in 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 either redeem or do not redeem your shares at the end of a period. The example also assumes that your investment has a 5% return each year, that the Fund’s operating expenses remain the same, and the contractual fee waivers currently in place are not renewed beyond October 31, 2014. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 most recent fiscal year, the Fund’s portfolio turnover rate was 176% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in bonds from issuers located around the world. The bonds in which the Fund may invest may be of any maturity and include: debt obligations of foreign governments; domestic and foreign corporate debt obligations, including obligations issued by special-purpose entities that are backed by corporate debt obligations; U.S. government securities (securities issued or guaranteed by the U.S. government or its agencies or instrumentalities); residential and commercial mortgage-backed securities; and asset-backed securities.

Under normal market conditions, the Fund invests at least 40% of its net assets in non-U.S. issuers and is invested in issuers located in at least three countries (including the United States). The Fund may invest in debt obligations issued by governmental and corporate issuers located in emerging markets countries.

The Fund invests in securities that are U.S. dollar-denominated and in securities that are denominated in foreign currencies. As described in more detail below, the Fund may utilize various currency-related derivatives in an effort to enhance the Fund's total return or to manage risk.

Up to 30% of the Fund's net assets may be invested in securities rated lower than investment grade or in unrated securities of comparable quality as determined by the Fund's sub-adviser (such securities commonly referred to as "high yield" or "junk bonds"). If the rating of a security is reduced or the credit quality of an unrated security declines after purchase, the Fund is not required to sell the security, but may consider doing so.

The Fund may utilize the following derivatives: options; futures contracts; options on futures contracts; interest rate caps, collars, and floors; foreign currency contracts; options on foreign currencies; swap agreements, including swap agreements on interest rates, currency rates, security indexes and specific securities, and credit default swap agreements; and options on the foregoing types of swap agreements. The Fund may enter into standardized derivatives contracts traded on domestic or foreign securities exchanges, boards of trade, or similar entities, and non-standardized derivatives contracts traded in the over-the-counter market. The Fund may use these derivatives in an attempt to manage market risk, currency risk, credit risk and yield curve risk, to manage the effective maturity or duration of securities in the Fund's portfolio or for speculative purposes in an effort to enhance returns. The Fund may also use derivatives to gain exposure to non-dollar denominated securities markets to the extent it does not do so through direct investments. The use of a derivative is speculative if the Fund is primarily seeking to enhance returns, rather than offset the risk of other positions. The Fund may not use any derivative to gain exposure to a security or type of security that it would be prohibited by its investment restrictions from purchasing directly.

The Fund's sub-adviser uses a team-based and research-driven investment process for the Fund. The portfolio management team relies on both top-down and bottom-up research to identify attractive investment opportunities and to manage the Fund's risk.

Principal Risks

The value of your investment in this Fund will change daily. You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund, listed alphabetically, include:

Call Risk—If an issuer calls higher-yielding debt instruments held by the Fund, performance could be adversely impacted.

Credit Risk—Credit risk is the risk that an issuer of a debt security may be unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer's ability or willingness to make such payments.

Currency Risk—Changes in currency exchange rates will affect the value of non-U.S. dollar denominated securities, interest earned from such securities, gains and losses realized on the sale of such securities, and derivative transactions tied to such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund's portfolio.

Derivatives Risk—The use of options; futures contracts; options on futures contracts; interest rate caps, collars, and floors; foreign currency contracts; options on foreign currencies; swap agreements, including swap agreements on interest rates, currency rates, security indexes and specific securities, and credit default swap agreements; and options on the foregoing types of swap agreements may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives can result in losses that greatly exceed the original investment. Derivatives can be highly volatile, illiquid and difficult to value. A derivative transaction also involves the risk that a loss may be sustained as a result of the failure of the counterparty to the contract to make required payments.

High Yield Securities Risk—High yield securities, which are rated below investment grade and commonly referred to as "junk" bonds, are high risk investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid and have more volatile prices than investment grade securities.

Income Risk—The Fund's income could decline during periods of falling interest rates.

Interest Rate Risk—Interest rate risk is the risk that the value of the Fund's portfolio will decline because of rising interest rates. When interest rates change, the values of longer-duration debt securities usually change more than the values of shorter-duration debt securities.

Mortgage- and Asset-Backed Securities Risk—These securities generally can be prepaid at any time. Prepayments that occur either more quickly or more slowly than expected can adversely impact the value of such securities. They are also subject to extension risk, which is the risk that rising interest rates could cause mortgages or other obligations underlying the securities to be prepaid more slowly than expected, thereby lengthening the duration of such securities, increasing their sensitivity to interest rate changes and causing their prices to decline. A mortgage-backed security may be negatively affected by the quality of the mortgages underlying such security, the credit quality of its issuer or guarantor, and the nature and structure of its credit support.

Non-U.S./Emerging Markets Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad and different legal, regulatory and tax environments. These additional risks may be heightened for securities of issuers located in, or with significant operations in, emerging market countries.

Fund Performance

The following bar chart and table provide some indication of the potential risks of investing in the Fund. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at www.nuveen.com/performance or by calling (800) 257-8787.

The bar chart below shows the Fund’s performance for Class A shares. The performance of the other share classes will differ due to their different expense structures. The bar chart and highest/lowest quarterly returns that follow do not reflect sales charges, and if these charges were reflected, the returns would be less than those shown.

Class A Annual Total Return

During the one-year period ended December 31, 2012, the Fund’s highest and lowest quarterly returns were 8.81% and -0.93%, respectively, for the quarters ended March 31, 2012 and June 30, 2012.

The table below shows the variability of the Fund’s average annual returns and how they compare over the time periods indicated with those of a broad measure of market performance and an index of funds with similar investment objectives. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown for Class A shares only; after-tax returns for other share classes will vary. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as IRAs or employer-sponsored retirement plans.

Both the bar chart and the table assume that all distributions have been reinvested. Performance reflects fee waivers, if any, in effect during the periods presented. If any such waivers were not in place, returns would be reduced.

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in equity securities of companies with market capitalizations at the time of investment comparable to companies in either the Russell 2000® Value Index or the Standard & Poor’s SmallCap 600 Index. As of September 30, 2013, the market cap range for the Russell 2000® Value Index was $42 million to $4.4 billion and the market cap range for the Standard & Poor’s SmallCap 600 Index was $100 million to $5.0 billion. The Fund will not be forced to sell a stock because it has exceeded or fallen below the current market capitalization range. The Fund’s sub-adviser seeks to identify under-valued companies with a catalyst to unlock value or improve profitability. The Fund’s sub-adviser maintains a long-term investment view and a focus on securities it believes can appreciate over an extended time, regardless of interim fluctuations. The Fund’s sub-adviser will sell securities or reduce positions if it feels that the company no longer possesses favorable risk/reward characteristics, attractive valuations or catalysts. The Fund invests primarily in U.S. equity securities, but it may invest up to 35% of its net assets in non-U.S. equity securities, including up to 10% of its net assets in equity securities of companies located in emerging market countries.

A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund’s portfolio. Equity Security Risk—Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular company, industry, or sector of the market. Non-U.S./Emerging Markets Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad and different legal, regulatory and tax environments. These additional risks may be heightened for securities of issuers located in, or with significant operations in, emerging market countries. Small-Cap Stock Risk—Small-cap stocks may involve greater risks than large-cap stocks. Prices of small-cap stocks may be subject to more abrupt or erratic movements, and to wider fluctuations, than stock prices of larger, more established companies or the market averages in general. It may be difficult to sell small-cap stocks at the desired time and price.
