Risk/Return [Heading]	rr_RiskReturnHeading	SPDR® Dow Jones REIT ETF
Objective [Heading]	rr_ObjectiveHeading	INVESTMENT OBJECTIVE
Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The SPDR Dow Jones REIT ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index that tracks the performance of publicly traded real estate investment trusts.
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 (“Shares”). This table and the example below do not reflect brokerage commissions you may pay on purchases and sales of the Fund’s Shares.
Operating Expenses Caption [Text]	rr_OperatingExpensesCaption	ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a  percentage of the value of your investment):
Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	PORTFOLIO TURNOVER:
Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 7% of the average value of its portfolio.
Portfolio Turnover, Rate	rr_PortfolioTurnoverRate	7.00%
Expense Exchange Traded Fund Commissions [Text]	rr_ExpenseExchangeTradedFundCommissions	This table and the example below do not reflect brokerage commissions you may pay on purchases and sales of the Fund’s Shares.
Expense Example [Heading]	rr_ExpenseExampleHeading	EXAMPLE:
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This example is intended to help you compare the cost of investing in 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 sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading]	rr_StrategyHeading	THE FUND’S PRINCIPAL INVESTMENT STRATEGY
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	In seeking to track the performance of the Dow Jones U.S. Select REIT Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests in substantially all of the securities represented in the Index in approximately the same proportions as the Index. Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities comprising the Index. The Fund will provide shareholders with at least 60 days notice prior to any material change in this 80% investment policy. In addition, the Fund may invest in equity securities that are not included in the Index, cash and cash equivalents or money market instruments, such as repurchase agreements and money market funds (including money market funds advised by SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund). The Index is designed to provide a measure of real estate securities that serve as proxies for direct real estate investing, in part by excluding securities whose value is not always closely tied to the value of the underlying real estate. The reason for the exclusions is that factors other than real estate supply and demand, such as interest rates, influence the market value of these companies. The Index is a market capitalization weighted index of publicly traded real estate investment trusts (“REITs”) and is comprised of companies whose charters are the equity ownership and operation of commercial real estate and which operate under the REIT Act of 1960. To be included in the Index, a company must be both an equity owner and operator of commercial and/or residential real estate. Businesses excluded from the Index include: mortgage REITs, net-lease REITs, real estate finance companies, mortgage brokers and bankers, commercial and residential real estate brokers and real estate agents, home builders, large landowners and subdividers of unimproved land, hybrid REITs, and timber REITs, as well as companies that have more than 25% of their assets in direct mortgage investments. A company must have a minimum total market capitalization of at least $200 million at the time of its inclusion, and at least 75% of the company’s total revenue must be derived from the ownership and operation of real estate assets. The liquidity of the company’s stock must be commensurate with that of other institutionally held real estate securities. The Index is generally rebalanced quarterly, and returns are calculated on a buy and hold basis except as necessary to reflect the occasional occurrence of Index changes in the middle of the month. Each REIT in the Index is weighted by its float-adjusted market capitalization. That is, each security is weighted to reflect the attainable market performance of the security which reflects that portion of securities shares that are accessible to investors. The Index is priced daily and is a total return (price and income) benchmark. As of September 30, 2012, the Index was comprised of 85 REITs. The Index is sponsored by S&P Dow Jones Indices LLC (the “Index Provider”) which is not affiliated with the Fund, the Adviser or the Sub-Adviser (as defined below). The Index Provider determines the composition of the Index, relative weightings of the securities in the Index and publishes information regarding the market value of the Index.
Risk [Heading]	rr_RiskHeading	PRINCIPAL RISKS OF INVESTING IN THE FUND
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund. PASSIVE STRATEGY/INDEX RISK:  The Fund is managed with a passive investment strategy, attempting to track the performance of an unmanaged index of securities. This differs from an actively managed fund, which typically seeks to outperform a benchmark index. As a result, the Fund may hold constituent securities of the Index regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Fund’s return to be lower than if the Fund employed an active strategy. INDEX TRACKING RISK:  While the Sub-Adviser seeks to track the performance of the Index as closely as possible (i.e., achieve a high degree of correlation with the Index), the Fund’s return may not match or achieve a high degree of correlation with the return of the Index due to operating expenses, transaction costs, cash flows, regulatory requirements and operational inefficiencies. For example, the Sub-Adviser anticipates that it may take several business days for additions and deletions to the Index to be reflected in the portfolio composition of the Fund. REAL ESTATE SECTOR RISK:  The Fund will concentrate its investments in the real estate sector. Adverse economic, business or political developments affecting real estate could have a major effect on the value of the Fund’s investments. Investing in real estate securities (which include REITs) may subject the Fund to risks associated with the direct ownership of real estate, such as decreases in real estate values, overbuilding, increased competition and other risks related to local or general economic conditions, increases in operating costs and property taxes, changes in zoning laws, casualty or condemnation losses, possible environmental liabilities, regulatory limitations on rent and fluctuations in rental income. Changes in interest rates may also affect the value of the Fund’s investment in real estate securities. Certain real estate securities have a relatively small market capitalization, which may tend to increase the volatility of the market price of these securities. Real estate securities are dependent upon specialized management skills, have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers. In addition, a REIT could fail to qualify for favorable tax treatment under the Internal Revenue Code of 1986, as amended and could fail to maintain exemption from the registration requirements of the Investment Company Act of 1940, as amended. EQUITY INVESTING RISK:  An investment in the Fund involves risks similar to those of investing in any fund of equity securities, such as market fluctuations, changes in interest rates and perceived trends in stock prices. NON-DIVERSIFICATION RISK:  The Fund is non-diversified and may invest a larger percentage of its assets in securities of a few issuers or a single issuer than that of a diversified fund. As a result, the Fund’s performance may be disproportionately impacted by the performance of relatively few securities.
Risk Lose Money [Text]	rr_RiskLoseMoney	As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund.
Risk Nondiversified Status [Text]	rr_RiskNondiversifiedStatus	NON-DIVERSIFICATION RISK:  The Fund is non-diversified and may invest a larger percentage of its assets in securities of a few issuers or a single issuer than that of a diversified fund.

SPDR(R) Russell 1000 ETF

SPDR^® Russell 1000^® ETF
(formerly, SPDR Dow Jones Large Cap ETF)

INVESTMENT OBJECTIVE

The SPDR Russell 1000 ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index that tracks the performance of large capitalization exchange traded U.S. equity securities.

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 (“Shares”). This table and the example below do not reflect brokerage commissions you may pay on purchases and sales of the Fund’s Shares.

ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment):

Annual Fund Operating Expenses		SPDR(R) Russell 1000 ETF
MANAGEMENT FEES	[1]	0.10%
DISTRIBUTION AND SERVICE (12b-1) FEES	[1][2]	none
OTHER EXPENSES	[1]	none
TOTAL ANNUAL FUND OPERATING EXPENSES	[1]	0.10%

EXAMPLE:

This 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 sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	YEAR 1	YEAR 3	YEAR 5	YEAR 10
SPDR(R) Russell 1000 ETF	10	32	56	128

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 4% of the average value of its portfolio.

THE FUND’S PRINCIPAL INVESTMENT STRATEGY

In seeking to track the performance of the Russell 1000 Index (the “Index”), the Fund employs a sampling strategy, which means that the Fund is not required to purchase all of the securities represented in the Index. Instead, the Fund may purchase a subset of the securities in the Index in an effort to hold a portfolio of securities with generally the same risk and return characteristics of the Index. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund, generally expects the Fund to hold less than the total number of securities in the Index, but reserves the right to hold as many securities as it believes necessary to achieve the Fund’s investment objective.

Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities comprising the Index. The Fund will provide shareholders with at least 60 days notice prior to any material change in this 80% investment policy. In addition, the Fund may invest in equity securities that are not included in the Index, cash and cash equivalents or money market instruments, such as repurchase agreements and money market funds (including money market funds advised by the Adviser.

The Index measures the performance of the large-cap segment of the U.S. equity universe. It is a subset of the Russell 3000^® Index and includes approximately 1,000 of the largest securities, which may include business development companies, based on a combination of their market cap and current index membership. The Russell 1000 Index represents approximately 92% of the U.S. market.

The Russell 1000 Index is constructed to provide a comprehensive and unbiased barometer for the large-cap segment and is completely reconstituted annually to ensure new and growing equities are reflected. As of June 30, 2013, the Index was comprised of 989 stocks.

The Index is sponsored by Russell Investment Group (the “Index Provider”) which is not affiliated with the Fund or the Adviser. The Index Provider determines the composition of the Index, relative weightings of the securities in the Index and publishes information regarding the market value of the Index.

PRINCIPAL RISKS OF INVESTING IN THE FUND

As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund.

PASSIVE STRATEGY/INDEX RISK:  The Fund is managed with a passive investment strategy, attempting to track the performance of an unmanaged index of securities. This differs from an actively managed fund, which typically seeks to outperform a benchmark index. As a result, the Fund may hold constituent securities of the Index regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Fund’s return to be lower than if the Fund employed an active strategy.

INDEX TRACKING RISK:  While the Adviser seeks to track the performance of the Index as closely as possible (i.e., achieve a high degree of correlation with the Index), the Fund’s return may not match or achieve a high degree of correlation with the return of the Index due to operating expenses, transaction costs, cash flows, regulatory requirements and operational inefficiencies. For example, the Adviser anticipates that it may take several business days for additions and deletions to the Index to be reflected in the portfolio composition of the Fund.

LARGE CAP RISK:  Returns on investments in stocks of large U.S. companies could trail the returns on investments in stocks of smaller and mid-sized companies.

EQUITY INVESTING RISK:  An investment in the Fund involves risks similar to those of investing in any fund of equity securities, such as market fluctuations, changes in interest rates and perceived trends in stock prices.

NON-DIVERSIFICATION RISK:  The Fund is non-diversified and may invest a larger percentage of its assets in securities of a few issuers or a single issuer than that of a diversified fund. As a result, the Fund’s performance may be disproportionately impacted by the performance of relatively few securities.

FUND PERFORMANCE

The following bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for certain time periods compare with the average annual returns of the Index. 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 online at http://www.spdrs.com.

ANNUAL TOTAL RETURN (years ended 12/31)

Highest Quarterly Return: 15.57% (Q2 2009)
Lowest Quarterly Return: -22.14% (Q4 2008)

AVERAGE ANNUAL TOTAL RETURNS (for periods ending 12/31/11)

The after-tax returns presented in the table below are calculated using highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Your actual after-tax returns will depend on your specific tax situation and may differ from those shown below. After-tax returns are not relevant to investors who hold Shares of the Fund through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The returns after taxes can exceed the return before taxes due to an assumed tax benefit for a shareholder from realizing a capital loss on a sale of Fund Shares. Effective July 9, 2013, the Fund changed its benchmark index from the Dow Jones U.S. Large-Cap Total Stock Market Index to the Russell 1000 Index. The Fund’s performance prior to July 9, 2013 is therefore based on the Fund’s prior investment strategy to track a different benchmark index.

SPDR(R) Russell Small Cap Completeness ETF

SPDR^® Russell Small Cap Completeness^® ETF
(formerly, SPDR Dow Jones Mid Cap ETF)

INVESTMENT OBJECTIVE

The SPDR Russell Small Cap Completeness ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index that tracks the performance of mid to small capitalization exchange traded U.S. equity securities.

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 (“Shares”). “Acquired Fund Fees and Expenses” reflect the Fund’s pro rata share of the fees and expenses incurred indirectly through its ownership in other investment companies, such as business development companies (“BDCs”). BDC expenses are similar to the expenses paid by any operating company held by the Fund. They are not direct costs paid by the Fund shareholders and are not used to calculate the Fund’s net asset value. They have no impact on the costs associated with fund operations. This table and the example below do not reflect brokerage commissions you may pay on purchases and sales of the Fund’s Shares.

ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment):

Annual Fund Operating Expenses		SPDR(R) Russell Small Cap Completeness ETF
MANAGEMENT FEES	[1]	0.10%
DISTRIBUTION AND SERVICE (12b-1) FEES	[1][2]	none
OTHER EXPENSES	[1]	none
ACQUIRED FUND FEES AND EXPENSES	[1][3]	0.06%
TOTAL ANNUAL FUND OPERATING EXPENSES	[1][3]	0.16%

EXAMPLE:

This 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 sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	YEAR 1	YEAR 3	YEAR 5	YEAR 10
SPDR(R) Russell Small Cap Completeness ETF	16	52	90	205

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 20% of the average value of its portfolio.

THE FUND’S PRINCIPAL INVESTMENT STRATEGY

In seeking to track the performance of the Russell Small Cap Completeness Index (the “Index”), the Fund employs a sampling strategy, which means that the Fund is not required to purchase all of the securities represented in the Index. Instead, the Fund may purchase a subset of the securities in the Index in an effort to hold a portfolio of securities with generally the same risk and return characteristics of the Index. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund, generally expects the Fund to hold less than the total number of securities in the Index, but reserves the right to hold as many securities as it believes necessary to achieve the Fund’s investment objective.

Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities comprising the Index. The Fund will provide shareholders with at least 60 days notice prior to any material change in this 80% investment policy. In addition, the Fund may invest in equity securities that are not included in the Index, cash and cash equivalents or money market instruments, such as repurchase agreements and money market funds (including money market funds advised by the Adviser).

The Index measures the performance of the Russell 3000^® Index companies including BDCs but excluding S&P 500^® constituents. The Index is constructed to provide a comprehensive and unbiased barometer of the extended broad market beyond the S&P 500 exposure. The Index is completely reconstituted annually to ensure new and growing equities are reflected. As of June 30, 2013, the Index was comprised of 2,427 securities.

The Index is sponsored by Russell Investment Group (the “Index Provider”) which is not affiliated with the Fund or the Adviser. The Index Provider determines the composition of the Index, relative weightings of the securities in the Index and publishes information regarding the market value of the Index.

Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Fund’s return to be lower than if the Fund employed an active strategy.

INDEX TRACKING RISK:  While the Adviser seeks to track the performance of the Index as closely as possible (i.e., achieve a high degree of correlation with the Index), the Fund’s return may not match or achieve a high degree of correlation with the return of the Index due to operating expenses, transaction costs, cash flows, regulatory requirements and operational inefficiencies. For example, the Adviser anticipates that it may take several business days for additions and deletions to the Index to be reflected in the portfolio composition of the Fund.

SMALL CAP RISK:  Small-sized companies may be more volatile and more likely than large- and mid-capitalization companies to have relatively limited product lines, markets or financial resources, or depend on a few key employees. Returns on investments in stocks of small companies could trail the returns on investments in stocks of larger companies.

MID CAP RISK:  Mid-sized companies may be more volatile and more likely than large-capitalization companies to have relatively limited product lines, markets or financial resources, or depend on a few key employees. Returns on investments in stocks of mid-size companies could trail the returns on investments in stocks of larger or smaller companies.

EQUITY INVESTING RISK:  An investment in the Fund involves risks similar to those of investing in any fund of equity securities, such as market fluctuations, changes in interest rates and perceived trends in stock prices.

NON-DIVERSIFICATION RISK:  The Fund is non-diversified and may invest a larger percentage of its assets in securities of a few issuers or a single issuer than that of a diversified fund. As a result, the Fund’s performance may be disproportionately impacted by the performance of relatively few securities.

FUND PERFORMANCE

The following bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for certain time periods compare with the average annual returns of the Index. 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 online at http://www.spdrs.com.

ANNUAL TOTAL RETURN (years ended 12/31)

Highest Quarterly Return: 22.89% (Q3 2009)
Lowest Quarterly Return: -25.80% (Q4 2008)

AVERAGE ANNUAL TOTAL RETURNS (for periods ending 12/31/11)

The after-tax returns presented in the table below are calculated using highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Your actual after-tax returns will depend on your specific tax situation and may differ from those shown below. After-tax returns are not relevant to investors who hold Shares of the Fund through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The returns after taxes can exceed the return before taxes due to an assumed tax benefit for a shareholder from realizing a capital loss on a sale of Fund Shares. Effective July 9, 2013, the Fund changed its benchmark index from the Dow Jones U.S. Mid-Cap Total Stock Market Index to the Russell Small Cap Completeness Index. The Fund’s performance prior to July 9, 2013 is therefore based on the Fund’s prior investment strategy to track a different benchmark index.

SPDR(R) Russell 3000 ETF

FUND SUMMARIES

SPDR^® Russell 3000^® ETF
(formerly, SPDR Dow Jones Total Market ETF)

INVESTMENT OBJECTIVE

The SPDR Russell 3000 ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index that tracks a broad universe of exchange traded U.S. equity securities.

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 (“Shares”). “Acquired Fund Fees and Expenses” reflect the Fund’s pro rata share of the fees and expenses incurred indirectly through its ownership in other investment companies, such as business development companies (“BDCs”). BDC expenses are similar to the expenses paid by any operating company held by the Fund. They are not direct costs paid by the Fund shareholders and are not used to calculate the Fund’s net asset value. They have no impact on the costs associated with fund operations. This table and the example below do not reflect brokerage commissions you may pay on purchases and sales of the Fund’s Shares.

ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment):

Annual Fund Operating Expenses		SPDR(R) Russell 3000 ETF
MANAGEMENT FEES	[1]	0.10%
DISTRIBUTION AND SERVICE (12b-1) FEES	[1]	none
OTHER EXPENSES	[1]	none
ACQUIRED FUND FEES AND EXPENSES	[1][2]	0.01%
TOTAL ANNUAL FUND OPERATING EXPENSES	[1][2]	0.11%

EXAMPLE:

This 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 sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	YEAR 1	YEAR 3	YEAR 5	YEAR 10
SPDR(R) Russell 3000 ETF	11	35	62	141

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 3% of the average value of its portfolio.

THE FUND’S PRINCIPAL INVESTMENT STRATEGY

In seeking to track the performance of the Russell 3000 Index (the “Index”), the Fund employs a sampling strategy, which means that the Fund is not required to purchase all of the securities represented in the Index. Instead, the Fund may purchase a subset of the securities in the Index in an effort to hold a portfolio of securities with generally the same risk and return characteristics of the Index. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund, generally expects the Fund to hold less than the total number of securities in the Index, but reserves the right to hold as many securities as it believes necessary to achieve the Fund’s investment objective.

Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities comprising the Index. The Fund will provide shareholders with at least 60 days notice prior to any material change in this 80% investment policy. In addition, the Fund may invest in equity securities that are not included in the Index, cash and cash equivalents or money market instruments, such as repurchase agreements and money market funds (including money market funds advised by the Adviser).

The Index measures the performance of the largest 3,000 U.S. companies, including BDCs, representing approximately 98% of the investable U.S. equity market. The Russell 3000 Index is constructed to provide a comprehensive, unbiased, and stable barometer of the broad market and is completely reconstituted annually to ensure new and growing equities are reflected. As of June 30, 2013, the Index was comprised of 2,923 stocks.

The Index is sponsored by Russell Investment Group (the “Index Provider”) which is not affiliated with the Fund or the Adviser. The Index Provider determines the composition of the Index, relative weightings of the securities in the Index and publishes information regarding the market value of the Index.

PRINCIPAL RISKS OF INVESTING IN THE FUND

As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund.

PASSIVE STRATEGY/INDEX RISK:  The Fund is managed with a passive investment strategy, attempting to track the performance of an unmanaged index of securities. This differs from an actively managed fund, which typically seeks to outperform a benchmark index. As a result, the Fund may hold constituent securities of the Index regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Fund’s return to be lower than if the Fund employed an active strategy.

INDEX TRACKING RISK:  While the Adviser seeks to track the performance of the Index as closely as possible (i.e., achieve a high degree of correlation with the Index), the Fund’s return may not match or achieve a high degree of correlation with the return of the Index due to operating expenses, transaction costs, cash flows, regulatory requirements and operational inefficiencies. For example, the Adviser anticipates that it may take several business days for additions and deletions to the Index to be reflected in the portfolio composition of the Fund.

EQUITY INVESTING RISK:  An investment in the Fund involves risks similar to those of investing in any fund of equity securities, such as market fluctuations, changes in interest rates and perceived trends in stock prices.

NON-DIVERSIFICATION RISK:  The Fund is non-diversified and may invest a larger percentage of its assets in securities of a few issuers or a single issuer than that of a diversified fund. As a result, the Fund’s performance may be disproportionately impacted by the performance of relatively few securities.

FUND PERFORMANCE

The following bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for certain time periods compare with the average annual returns of the Index. 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 online at http://www.spdrs.com.

ANNUAL TOTAL RETURN (years ended 12/31)

Highest Quarterly Return: 16.30% (Q2 2009)
Lowest Quarterly Return: -22.49% (Q4 2008)

AVERAGE ANNUAL TOTAL RETURNS (for periods ending 12/31/11)

The after-tax returns presented in the table below are calculated using highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Your actual after-tax returns will depend on your specific tax situation and may differ from those shown below. After-tax returns are not relevant to investors who hold Shares of the Fund through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The returns after taxes can exceed the return before taxes due to an assumed tax benefit for a shareholder from realizing a capital loss on a sale of Fund Shares. Effective July 9, 2013, the Fund changed its benchmark index from the Dow Jones U.S. Total Stock Market Index to the Russell 3000 Index. The Fund’s performance prior to July 9, 2013 is therefore based on the Fund’s prior investment strategy to track a different benchmark index. Prior to June 14, 2005, the Fund’s investment strategy sought to track the total return performance of an index different from the Dow Jones U.S. Total Stock Market Index. Performance of the Fund prior to June 14, 2005 is therefore based on the Fund’s investment strategy to track the prior index.

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 3% 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 sell all of your Shares at the end of those periods.

Strategy [Heading]	rr_StrategyHeading	THE FUND’S PRINCIPAL INVESTMENT STRATEGY
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	In seeking to track the performance of the Russell 3000 Index (the “Index”), the Fund employs a sampling strategy, which means that the Fund is not required to purchase all of the securities represented in the Index. Instead, the Fund may purchase a subset of the securities in the Index in an effort to hold a portfolio of securities with generally the same risk and return characteristics of the Index. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund, generally expects the Fund to hold less than the total number of securities in the Index, but reserves the right to hold as many securities as it believes necessary to achieve the Fund’s investment objective. Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities comprising the Index. The Fund will provide shareholders with at least 60 days notice prior to any material change in this 80% investment policy. In addition, the Fund may invest in equity securities that are not included in the Index, cash and cash equivalents or money market instruments, such as repurchase agreements and money market funds (including money market funds advised by the Adviser). The Index measures the performance of the largest 3,000 U.S. companies, including BDCs, representing approximately 98% of the investable U.S. equity market. The Russell 3000 Index is constructed to provide a comprehensive, unbiased, and stable barometer of the broad market and is completely reconstituted annually to ensure new and growing equities are reflected. As of June 30, 2013, the Index was comprised of 2,923 stocks. The Index is sponsored by Russell Investment Group (the “Index Provider”) which is not affiliated with the Fund or the Adviser. The Index Provider determines the composition of the Index, relative weightings of the securities in the Index and publishes information regarding the market value of the Index.
Risk [Heading]	rr_RiskHeading	PRINCIPAL RISKS OF INVESTING IN THE FUND
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund. PASSIVE STRATEGY/INDEX RISK:  The Fund is managed with a passive investment strategy, attempting to track the performance of an unmanaged index of securities. This differs from an actively managed fund, which typically seeks to outperform a benchmark index. As a result, the Fund may hold constituent securities of the Index regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Fund’s return to be lower than if the Fund employed an active strategy. INDEX TRACKING RISK:  While the Adviser seeks to track the performance of the Index as closely as possible (i.e., achieve a high degree of correlation with the Index), the Fund’s return may not match or achieve a high degree of correlation with the return of the Index due to operating expenses, transaction costs, cash flows, regulatory requirements and operational inefficiencies. For example, the Adviser anticipates that it may take several business days for additions and deletions to the Index to be reflected in the portfolio composition of the Fund. EQUITY INVESTING RISK:  An investment in the Fund involves risks similar to those of investing in any fund of equity securities, such as market fluctuations, changes in interest rates and perceived trends in stock prices. NON-DIVERSIFICATION RISK:  The Fund is non-diversified and may invest a larger percentage of its assets in securities of a few issuers or a single issuer than that of a diversified fund. As a result, the Fund’s performance may be disproportionately impacted by the performance of relatively few securities.

MANAGEMENT FEES		0.25%
DISTRIBUTION AND SERVICE (12b-1) FEES	[1]	none
OTHER EXPENSES		none
TOTAL ANNUAL FUND OPERATING EXPENSES		0.25%

EXAMPLE:

This 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 sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	YEAR 1	YEAR 3	YEAR 5	YEAR 10
SPDR(R) Dow Jones REIT ETF	26	80	141	318

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 7% of the average value of its portfolio.

THE FUND’S PRINCIPAL INVESTMENT STRATEGY

In seeking to track the performance of the Dow Jones U.S. Select REIT Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests in substantially all of the securities represented in the Index in approximately the same proportions as the Index.

Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities comprising the Index. The Fund will provide shareholders with at least 60 days notice prior to any material change in this 80% investment policy. In addition, the Fund may invest in equity securities that are not included in the Index, cash and cash equivalents or money market instruments, such as repurchase agreements and money market funds (including money market funds advised by SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index is designed to provide a measure of real estate securities that serve as proxies for direct real estate investing, in part by excluding securities whose value is not always closely tied to the value of the underlying real estate. The reason for the exclusions is that factors other than real estate supply and demand, such as interest rates, influence the market value of these companies. The Index is a market capitalization weighted index of publicly traded real estate investment trusts (“REITs”) and is comprised of companies whose charters are the equity ownership and operation of commercial real estate and which operate under the REIT Act of 1960. To be included in the Index, a company must be both an equity owner and operator of commercial and/or residential real estate. Businesses excluded from the Index include: mortgage REITs, net-lease REITs, real estate finance companies, mortgage brokers and bankers, commercial and residential real estate brokers and real estate agents, home builders, large landowners and subdividers of unimproved land, hybrid REITs, and timber REITs, as well as companies that have more than 25% of their assets in direct mortgage investments. A company must have a minimum total market capitalization of at least $200 million at the time of its inclusion, and at least 75% of the company’s total revenue must be derived from the ownership and operation of real estate assets. The liquidity of the company’s stock must be commensurate with that of other institutionally held real estate securities. The Index is generally rebalanced quarterly, and returns are calculated on a buy and hold basis except as necessary to reflect the occasional occurrence of Index changes in the middle of the month. Each REIT in the Index is weighted by its float-adjusted market capitalization. That is, each security is weighted to reflect the attainable market performance of the security which reflects that portion of securities shares that are accessible to investors. The Index is priced daily and is a total return (price and income) benchmark. As of September 30, 2012, the Index was comprised of 85 REITs.

The Index is sponsored by S&P Dow Jones Indices LLC (the “Index Provider”) which is not affiliated with the Fund, the Adviser or the Sub-Adviser (as defined below). The Index Provider determines the composition of the Index, relative weightings of the securities in the Index and publishes information regarding the market value of the Index.

PRINCIPAL RISKS OF INVESTING IN THE FUND

As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund.

PASSIVE STRATEGY/INDEX RISK:  The Fund is managed with a passive investment strategy, attempting to track the performance of an unmanaged index of securities. This differs from an actively managed fund, which typically seeks to outperform a benchmark index. As a result, the Fund may hold constituent securities of the Index regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Fund’s return to be lower than if the Fund employed an active strategy.

INDEX TRACKING RISK:  While the Sub-Adviser seeks to track the performance of the Index as closely as possible (i.e., achieve a high degree of correlation with the Index), the Fund’s return may not match or achieve a high degree of correlation with the return of the Index due to operating expenses, transaction costs, cash flows, regulatory requirements and operational inefficiencies. For example, the Sub-Adviser anticipates that it may take several business days for additions and deletions to the Index to be reflected in the portfolio composition of the Fund.

REAL ESTATE SECTOR RISK:  The Fund will concentrate its investments in the real estate sector. Adverse economic, business or political developments affecting real estate could have a major effect on the value of the Fund’s investments. Investing in real estate securities (which include REITs) may subject the Fund to risks associated with the direct ownership of real estate, such as decreases in real estate values, overbuilding, increased competition and other risks related to local or general economic conditions, increases in operating costs and property taxes, changes in zoning laws, casualty or condemnation losses, possible environmental liabilities, regulatory limitations on rent and fluctuations in rental income. Changes in interest rates may also affect the value of the Fund’s investment in real estate securities. Certain real estate securities have a relatively small market capitalization, which may tend to increase the volatility of the market price of these securities. Real estate securities are dependent upon specialized management skills, have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers. In addition, a REIT could fail to qualify for favorable tax treatment under the Internal Revenue Code of 1986, as amended and could fail to maintain exemption from the registration requirements of the Investment Company Act of 1940, as amended.

EQUITY INVESTING RISK:  An investment in the Fund involves risks similar to those of investing in any fund of equity securities, such as market fluctuations, changes in interest rates and perceived trends in stock prices.

NON-DIVERSIFICATION RISK:  The Fund is non-diversified and may invest a larger percentage of its assets in securities of a few issuers or a single issuer than that of a diversified fund. As a result, the Fund’s performance may be disproportionately impacted by the performance of relatively few securities.

FUND PERFORMANCE

The following bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for certain time periods compare with the average annual returns of the Index. 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 online at http://www.spdrs.com.

ANNUAL TOTAL RETURN (years ended 12/31)

Highest Quarterly Return: 35.38% (Q3 2009)
Lowest Quarterly Return: -39.70% (Q4 2008)

AVERAGE ANNUAL TOTAL RETURNS (for periods ending 12/31/11)

The after-tax returns presented in the table below are calculated using highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Your actual after-tax returns will depend on your specific tax situation and may differ from those shown below. After-tax returns are not relevant to investors who hold Shares of the Fund through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The returns after taxes can exceed the return before taxes due to an assumed tax benefit for a shareholder from realizing a capital loss on a sale of Fund Shares.
