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).

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.

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 non-U.S. issuers that trade in U.S. or non-U.S. markets, depositary receipts representing shares of non-U.S. issuers, and exchange-traded funds and other investment companies ("investment companies") that provide exposure to non-U.S. issuers. The Fund considers an issuer to be non-U.S. if it is organized, domiciled, or has a principal place of business outside the United States. The Fund diversifies its investments among a number of different countries throughout the world and may invest in companies of any size. The Fund may utilize options, futures contracts, options on futures contracts, and forward foreign currency exchange contracts ("derivatives"). The Fund may use these derivatives to manage market or business risk, enhance the Fund's return, or hedge against adverse movements in currency exchange rates. Nuveen Asset Management, LLC ("Nuveen Asset Management"), Altrinsic Global Advisors, LLC ("Altrinsic") and Lazard Asset Management LLC ("Lazard") act as the Fund's sub-advisers. The sub-advisers employ different investment strategies, which are intended to complement one another: Altrinsic employs a value strategy, emphasizing investment in equity securities of companies trading below intrinsic valuations with stable returns and companies trading at steep discounts to intrinsic valuations with catalysts for an improvement in returns. Lazard employs an emerging markets strategy, emphasizing investments in equity securities of companies whose principal activities are located in emerging market countries that are believed to be undervalued based on their earnings, cash flow or asset values. A country is considered to be an "emerging market" if it is defined as such by Morgan Stanley Capital International Inc. Nuveen Asset Management invests the Fund's assets using three distinct strategies: Nuveen Asset Management's international growth team employs a growth strategy, emphasizing investments in equity securities of companies with superior growth characteristics, including superior profitability, secular growth, sustainable competitive advantage, and strong capital structure. Nuveen Asset Management's infrastructure team will be allocated up to 10% of the Fund's total assets, and will focus on equity securities of infrastructure-related companies. Nuveen Asset Management's asset allocation team may invest in derivatives, other investment companies, and money market instruments and other short-term securities. These investments may be used as an investment "overlay" for the purpose of increasing or reducing the Fund's exposure to certain companies, industry sectors, countries, regions, or investment styles, or for such other reasons as Nuveen Asset Management deems advisable. They also may be used to facilitate cash flows to and from the sub-advisers, to meet redemptions requests, and to pay Fund expenses. Decisions on how to allocate the Fund's assets between the sub-advisers and among the different investment strategies are made by Nuveen Asset Management's asset allocation team. Allocation determinations are based on a variety of factors, including performance records and the characteristics of typical portfolio investments for the different strategies. These characteristics may include capitalization size, growth and profitability measures, valuation measures, economic sector weightings, and earnings and price volatility statistics. Allocations will vary over time according to the prospective returns and risks associated with the various investment strategies.
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The value of your investment in this Fund will change daily, which means you could lose money. 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 include: Derivatives Risk—The use of derivatives involves additional risks, such as liquidity, interest rate, counterparty, market, credit and management 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 could have a large impact on performance. Recent legislation requires the development of a new regulatory framework for the derivatives market. The impact of the new regulations is still unknown, but has the potential to increase the costs of using derivatives, may limit the availability of some forms of derivatives or the Fund's ability to use derivatives, and may adversely affect the performance of some derivative instruments used by the Fund as well as the Fund's ability to pursue its investment objective through the use of such instruments. Equity Security Risk—Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry, or sector of the market. Infrastructure Sector Risk—Because the Fund may invest in infrastructure-related securities, the Fund could have greater exposure to adverse economic, regulatory, political, legal and other changes affecting the issuers of such securities. Multi-Manager Risk—Each sub-adviser makes investment decisions independently and it is possible that the security selection process of the sub-advisers may not complement one another. The sub-advisers selected may underperform the market generally or other sub-advisers that could have been selected. 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. Also, changes in currency exchange rates may affect the Fund's net asset value, the value of dividends and interest earned, and gains and losses realized on the sale of securities. Other Investment Companies Risk—When the Fund invests in other investment companies, you bear both your proportionate share of Fund expenses and, indirectly, the expenses of the other investment companies. 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.

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 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 February 28, 2014. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

10 Years	2,332	2,653	1,587

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 primarily in equity securities of non-U.S. issuers that trade in U.S. or non-U.S. markets, depositary receipts representing shares of non-U.S. issuers, and exchange-traded funds and other investment companies ("investment companies") that provide exposure to non-U.S. issuers. The Fund considers an issuer to be non-U.S. if it is organized, domiciled, or has a principal place of business outside the United States. The Fund diversifies its investments among a number of different countries throughout the world and may invest in companies of any size.

The Fund may utilize options, futures contracts, options on futures contracts, and forward foreign currency exchange contracts ("derivatives"). The Fund may use these derivatives to manage market or business risk, enhance the Fund's return, or hedge against adverse movements in currency exchange rates.

Nuveen Asset Management, LLC ("Nuveen Asset Management"), Altrinsic Global Advisors, LLC ("Altrinsic") and Lazard Asset Management LLC ("Lazard") act as the Fund's sub-advisers. The sub-advisers employ different investment strategies, which are intended to complement one another:

These investments may be used as an investment "overlay" for the purpose of increasing or reducing the Fund's exposure to certain companies, industry sectors, countries, regions, or investment styles, or for such other reasons as Nuveen Asset Management deems advisable. They also may be used to facilitate cash flows to and from the sub-advisers, to meet redemptions requests, and to pay Fund expenses.

Decisions on how to allocate the Fund's assets between the sub-advisers and among the different investment strategies are made by Nuveen Asset Management's asset allocation team. Allocation determinations are based on a variety of factors, including performance records and the characteristics of typical portfolio investments for the different strategies. These characteristics may include capitalization size, growth and profitability measures, valuation measures, economic sector weightings, and earnings and price volatility statistics. Allocations will vary over time according to the prospective returns and risks associated with the various investment strategies.

Principal Risks

The value of your investment in this Fund will change daily, which means you could lose money. 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 include:

Derivatives Risk—The use of derivatives involves additional risks, such as liquidity, interest rate, counterparty, market, credit and management 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 could have a large impact on performance. Recent legislation requires the development of a new regulatory framework for the derivatives market. The impact of the new regulations is still unknown, but has the potential to increase the costs of using derivatives, may limit the availability of some forms of derivatives or the Fund's ability to use derivatives, and may adversely affect the performance of some derivative instruments used by the Fund as well as the Fund's ability to pursue its investment objective through the use of such instruments.

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

Infrastructure Sector Risk—Because the Fund may invest in infrastructure-related securities, the Fund could have greater exposure to adverse economic, regulatory, political, legal and other changes affecting the issuers of such securities.

Multi-Manager Risk—Each sub-adviser makes investment decisions independently and it is possible that the security selection process of the sub-advisers may not complement one another. The sub-advisers selected may underperform the market generally or other sub-advisers that could have been selected.

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. Also, changes in currency exchange rates may affect the Fund's net asset value, the value of dividends and interest earned, and gains and losses realized on the sale of securities.

Other Investment Companies Risk—When the Fund invests in other investment companies, you bear both your proportionate share of Fund expenses and, indirectly, the expenses of the other investment companies.

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 six-year period ended December 31, 2012, the Fund’s highest and lowest quarterly returns were 24.92% and -21.70%, respectively, for the quarters ended June 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. 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 [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests primarily in equity securities of non-U.S. issuers that trade in U.S. or non-U.S. markets, depositary receipts representing shares of non-U.S. issuers, and exchange-traded funds and other investment companies ("investment companies") that provide exposure to non-U.S. issuers. The Fund considers an issuer to be non-U.S. if it is organized, domiciled, or has a principal place of business outside the United States. The Fund diversifies its investments among a number of different countries throughout the world and may invest in companies of any size. Up to 15% of the Fund's total assets may be invested in equity securities of emerging markets issuers. A country is considered to be an "emerging market" if it is defined as such by Morgan Stanley Capital International Inc. The Fund may utilize options, futures contracts, options on futures contracts, and forward foreign currency exchange contracts ("derivatives"). The Fund may use these derivatives to manage market or business risk, enhance the Fund's return, or hedge against adverse movements in currency exchange rates. Nuveen Asset Management, LLC ("Nuveen Asset Management") and Altrinsic Global Advisors, LLC ("Altrinsic") act as the Fund's sub-advisers. The sub-advisers employ different investment strategies, which are intended to complement one another: Altrinsic employs a value strategy, emphasizing investment in equity securities of companies trading below intrinsic valuations with stable returns and companies trading at steep discounts to intrinsic valuations with catalysts for an improvement in returns. Nuveen Asset Management invests the Fund's assets using three distinct strategies: Nuveen Asset Management's international growth team employs a growth strategy, emphasizing investments in equity securities of companies with superior growth characteristics, including superior profitability, secular growth, sustainable competitive advantage, and strong capital structure. Nuveen Asset Management's infrastructure team will be allocated up to 10% of the Fund's total assets, and will focus on equity securities of infrastructure-related companies. Nuveen Asset Management's asset allocation team may invest in derivatives, other investment companies, and money market instruments and other short-term securities. These investments may be used as an investment "overlay" for the purpose of increasing or reducing the Fund's exposure to certain companies, industry sectors, countries, regions, or investment styles, or for such other reasons as Nuveen Asset Management deems advisable. They also may be used to facilitate cash flows to and from the sub-advisers, to meet redemptions requests, and to pay Fund expenses. Decisions on how to allocate the Fund's assets between the sub-advisers and among the different investment strategies are made by Nuveen Asset Management's asset allocation team. Allocation determinations are based on a variety of factors, including performance records and the characteristics of typical portfolio investments for the different strategies. These characteristics may include capitalization size, growth and profitability measures, valuation measures, economic sector weightings, and earnings and price volatility statistics. Allocations will vary over time according to the prospective returns and risks associated with the various investment strategies.

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 February 28, 2014. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Redemption

Expense Example Nuveen International Fund (USD $)	A	C	R3	I
1 Year	722	231	181	130
3 Years	1,122	807	660	503
5 Years	1,546	1,409	1,166	901
10 Years	2,724	3,037	2,558	2,014

No Redemption

Expense Example, No Redemption Nuveen International Fund (USD $)	A	C	R3	I
1 Year	722	231	181	130
3 Years	1,122	807	660	503
5 Years	1,546	1,409	1,166	901
10 Years	2,724	3,037	2,558	2,014

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 57% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests primarily in equity securities of non-U.S. issuers that trade in U.S. or non-U.S. markets, depositary receipts representing shares of non-U.S. issuers, and exchange-traded funds and other investment companies ("investment companies") that provide exposure to non-U.S. issuers. The Fund considers an issuer to be non-U.S. if it is organized, domiciled, or has a principal place of business outside the United States. The Fund diversifies its investments among a number of different countries throughout the world and may invest in companies of any size.

Up to 15% of the Fund's total assets may be invested in equity securities of emerging markets issuers. A country is considered to be an "emerging market" if it is defined as such by Morgan Stanley Capital International Inc.

The Fund may utilize options, futures contracts, options on futures contracts, and forward foreign currency exchange contracts ("derivatives"). The Fund may use these derivatives to manage market or business risk, enhance the Fund's return, or hedge against adverse movements in currency exchange rates.

Nuveen Asset Management, LLC ("Nuveen Asset Management") and Altrinsic Global Advisors, LLC ("Altrinsic") act as the Fund's sub-advisers. The sub-advisers employ different investment strategies, which are intended to complement one another:

• Altrinsic employs a value strategy, emphasizing investment in equity securities of companies trading below intrinsic valuations with stable returns and companies trading at steep discounts to intrinsic valuations with catalysts for an improvement in returns.

• Nuveen Asset Management invests the Fund's assets using three distinct strategies:

• Nuveen Asset Management's international growth team employs a growth strategy, emphasizing investments in equity securities of companies with superior growth characteristics, including superior profitability, secular growth, sustainable competitive advantage, and strong capital structure.

• Nuveen Asset Management's infrastructure team will be allocated up to 10% of the Fund's total assets, and will focus on equity securities of infrastructure-related companies.

• Nuveen Asset Management's asset allocation team may invest in derivatives, other investment companies, and money market instruments and other short-term securities. These investments may be used as an investment "overlay" for the purpose of increasing or reducing the Fund's exposure to certain companies, industry sectors, countries, regions, or investment styles, or for such other reasons as Nuveen Asset Management deems advisable. They also may be used to facilitate cash flows to and from the sub-advisers, to meet redemptions requests, and to pay Fund expenses.

Decisions on how to allocate the Fund's assets between the sub-advisers and among the different investment strategies are made by Nuveen Asset Management's asset allocation team. Allocation determinations are based on a variety of factors, including performance records and the characteristics of typical portfolio investments for the different strategies. These characteristics may include capitalization size, growth and profitability measures, valuation measures, economic sector weightings, and earnings and price volatility statistics. Allocations will vary over time according to the prospective returns and risks associated with the various investment strategies.

Principal Risks

The value of your investment in this Fund will change daily, which means you could lose money. 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 include:

Derivatives Risk—The use of derivatives involves additional risks, such as liquidity, interest rate, counterparty, market, credit and management 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 could have a large impact on performance. Recent legislation requires the development of a new regulatory framework for the derivatives market. The impact of the new regulations is still unknown, but has the potential to increase the costs of using derivatives, may limit the availability of some forms of derivatives or the Fund's ability to use derivatives, and may adversely affect the performance of some derivative instruments used by the Fund as well as the Fund's ability to pursue its investment objective through the use of such instruments.

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

Infrastructure Sector Risk—Because the Fund may invest in infrastructure-related securities, the Fund could have greater exposure to adverse economic, regulatory, political, legal and other changes affecting the issuers of such securities.

Multi-Manager Risk—Each sub-adviser makes investment decisions independently and it is possible that the security selection process of the sub-advisers may not complement one another. The sub-advisers selected may underperform the market generally or other sub-advisers that could have been selected.

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. Also, changes in currency exchange rates may affect the Fund's net asset value, the value of dividends and interest earned, and gains and losses realized on the sale of securities.

Other Investment Companies Risk—When the Fund invests in other investment companies, you bear both your proportionate share of Fund expenses and, indirectly, the expenses of the other investment companies.

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 ten-year period ended December 31, 2012, the Fund’s highest and lowest quarterly returns were 22.24% and -20.22%, respectively, for the quarters ended June 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. 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.

Prior to July 1, 2004, Class R3 shares were designated Class S shares, which had lower fees and expenses. The performance information in the table prior to July 1, 2004 is based on the performance of the Class S shares. If current fees and expenses had been in effect, performance would have been lower.
