Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy [Heading]18false 4rr_StrategyNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00 The Fund seeks to achieve its investment objective by investing in a diversified portfolio of fixed income debt instruments of varying maturities. The Fund normally invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in U.S. dollar-denominated, investment-grade fixed income debt instruments. This investment policy may be changed by the Fund upon 60 days' prior notice to shareholders. "Fixed income debt instruments" include bonds, debt securities and other similar instruments issued by various U.S. and non-U.S. public- or private-sector entities. Schroders serves as the investment adviser for the Fund and is responsible for oversight of the Fund's sub-adviser, STW, which provides day-to-day portfolio management of the Fund. The fixed income debt instruments in which the Fund may invest include securities issued or guaranteed by the U.S. Government and its agencies; government-sponsored enterprise securities; corporate bonds; mortgage-backed securities (including "to be announced" transactions); asset-backed securities; municipal securities; sovereign debt and debt securities issued by supranational organizations. "Investment-grade" securities are securities that are rated by at least one major rating agency in one of its top four rating categories, or, if unrated, that are determined by STW to be of similar quality, at the time of purchase. In the case of a split rated security (that is, two or more rating agencies give a security different ratings), the highest rating shall apply. The Fund may invest without limit in US dollar denominated foreign securities. The Fund may also invest a portion of its assets in cash and cash equivalents. While the Fund may invest in fixed income securities of any maturity or duration, under normal market conditions, STW seeks to maintain an effective portfolio duration that is within +/- 1 year of the duration of the Fund's benchmark, the Barclays U.S. Long Government/Credit Bond Index. As of September 30, 2012, the effective duration of the Barclays U.S. Long Government/Credit Bond Index was 14.8 years. Duration is a measure of a bond price's sensitivity to a given change in interest rates. Generally, the longer a bond's duration, the greater its price sensitivity to a change in interest rates. In contrast to duration, maturity measures only the time until final payment is due. STW's decision to purchase or sell a security or make investments in a particular sector is based on relative value considerations. In analyzing the relative attractiveness of a particular security or sector, STW assesses an issue's historical relationships to other bonds, technical factors including supply and demand and fundamental risk and reward relationships. When making decisions to purchase or sell a security, STW also considers a number of factors including sector exposures, interest rate duration, yield and the relationship between yields and maturity dates. The "total return" sought by the Fund consists of income earned on the Fund's investments, plus capital appreciation, if any. The Fund may engage in active and frequent trading of portfolio securities in seeking to achieve its investment objective. falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

The Fund will be affected by the investment decisions, techniques and risk analyses of the Fund's investment team and there is no guarantee that the Fund will achieve its investment objective. The values of investments held by the Fund may fluctuate in response to actual or perceived issuer, political, market, and economic factors influencing the financial markets generally, or relevant industries or sectors within them. Fluctuations may be more pronounced if the Fund invests substantially in one country or group of countries or in companies with smaller market capitalizations. Other principal risks of investing in the Fund include: •  Interest Rate Risk: fixed income, or debt, securities may decline in value due to changes in interest rates, extended duration of principal payments at below-market interest rate, or prepayment. Interest rate risk is generally greater for investments with longer durations or maturities; •  Credit Risk: the ability, or perceived ability, of the issuer of a debt security to make timely payments of interest and principal will affect the security's value; •  Rating Agencies Risk: ratings are not an absolute standard of quality, but rather general indicators that reflect only the view of the originating rating agencies from which an explanation of the significance of such ratings may be obtained. There is no assurance that a particular rating will continue for any given period of time or that any such rating will not be revised downward or withdrawn entirely if, in the judgment of the agency establishing the rating, circumstances so warrant. A downward revision or withdrawal of such ratings, or both, may have an effect on the liquidity or market price of the securities in which the Fund invests; •  Inflation/Deflation Risk: the value of the Fund's investments may decline as inflation reduces the value of money; conversely, if deflation reduces prices throughout the economy there may be an adverse effect on the creditworthiness of issuers in whose securities the Fund invests; •  Mortgage-Backed and Asset-Backed Securities Risk: investing in mortgage- and asset-backed securities involves interest rate, credit, valuation, extension and liquidity risks and the risk that payments on the underlying assets are delayed, prepaid, subordinated or defaulted on; •  "To Be Announced" Transactions Risk: default by or bankruptcy of a counterparty to a TBA transaction would expose the Fund to possible losses because of an adverse market action, expenses or delays in connection with the purchase or sale of the pools of mortgage pass-through securities specified in the TBA transaction; •  U.S. Government Securities Risk: securities issued or guaranteed by certain agencies and instrumentalities of the U.S. Government may not be supported by the full faith and credit of the United States and investing in such securities involves interest rate, extension and mortgage and asset-backed securities risks; •  Liquidity Risk: illiquid securities may be highly volatile, difficult to value, and difficult to sell or close out at favorable prices or times. Investments in foreign securities, including emerging market securities, tend to have greater exposure to liquidity risk; •  Municipal Securities Risk: economic, political or regulatory changes may impact the ability of municipal issuers to repay principal and to make interest payments on municipal securities. Changes in the financial condition or credit rating of municipal issuers also may adversely affect the value of the Fund's municipal securities; •  Foreign Securities Risk: investments in non-U.S. issuers, directly or through use of depositary receipts, may be affected by adverse political, regulatory, economic, market or other developments affecting issuers located in foreign countries, currency exchange rates or regulations, or foreign withholding taxes; and •  Portfolio Turnover Risk: if the Fund frequently trades its securities, this will increase transaction costs, may result in taxable capital gains, and may lower investment performance. Please see "Principal Risks of Investing in the Funds" in the Fund's full prospectus for a more detailed description of the Fund's risks. 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. falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their shares in the Fund through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. In some cases, the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. falsefalsefalsenonnum:textBlockItemTypenaIf the Fund has annual returns for at least one calendar year, provide a table showing the Fund's (A) average annual total return; (B) average annual total return (after taxes on distributions); and (C) average annual total return (after taxes on distributions and redemption). A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____)Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iii false0Performance Table Closing [Text Block]falseRisk/Return Summary - Schroder Long Duration Investment-Grade Bond Fund (Schroder Long Duration Investment-Grade Bond Fund)UnKnownUnKnownUnKnownUnKnowntruefalsefalseSheethttp://schroder.com/20130620/role/DocumentRiskReturnSummaryUnlabeledSchroderLongDurationInvestmentGradeBondFund128
