Strategy [Heading] Principal Investment Strategies                                
Strategy Narrative [Text Block] Normally investing at least 80% of assets in U.S. stocks and in shares of other U.S. stock funds. Stocks are a type of equity security that represent an ownership interest in an issuer. Stocks include common stocks (including depositary receipts evidencing ownership of common stock) and preferred stocks. U.S. stock funds are funds (including mutual funds and ETFs) that invest at least 80% of assets in U.S. stocks. Whether an underlying fund is included in the fund's 80% policy is determined at the time of investment and evaluated periodically thereafter. The Adviser considers a number of factors to determine whether an issuer is located in or tied economically to a particular country or region including: whether a third-party vendor has assigned a particular country or region classification to the issuer or included the issuer in an index representative of a particular country or region; the issuer's domicile, incorporation, and location of assets; whether the issuer derives at least 50% of its revenues from, or has at least 50% of its assets in, a particular country or region; the source of government guarantees (if any); and the primary trading market or listing exchange. Whether an issuer is located in or tied economically to a particular country can be determined under any of these factors. Derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the fund's 80% policy, consistent with the fund's investment policies and limitations with respect to investments in derivatives.

Performance Narrative [Text Block] Effective August 16, 2024, Strategic Advisers ® Large Cap Fund ("Predecessor Fund") and another fund were reorganized into the fund ("Reorganization"). The Predecessor Fund, which had an investment objective that was identical to the fund's, was designated as the accounting survivor in the Reorganization. As a result, the fund has assumed the Predecessor Fund's historical performance, which includes the historical performance of Strategic Advisers ® Core Fund for periods prior to November 20, 2020 which was assumed by the Predecessor Fund in a prior reorganization. The performance information shown below in Year-by-Year Returns and Average Annual Returns includes performance information of the Predecessor Fund, which had a different fee structure than the fund, for all periods prior to the Reorganization. Past performance may have been different if the fund's current fee structure had been in place during the period. The following information is intended to help you understand the risks of investing in the fund. The information illustrates the changes in the performance of the fund's shares from year to year and compares the performance of the fund's shares to the performance of a securities market index and an additional index over various periods of time. The additional index has characteristics relevant to the fund's investment strategies. Index descriptions appear in the "Additional Index Information" section of the prospectus.

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 operating expenses or in the example, affect the fund's performance . For the period from June 23, 2025 to May 31, 2026, the fund's portfolio turnover rate was 47 % (annualized) of the average value of its portfolio.

Strategy [Heading] Principal Investment Strategies                                
Strategy Narrative [Text Block] Normally investing at least 80% of assets in debt securities and in shares of other debt funds. Debt securities are used by issuers to borrow money. The issuer usually pays a fixed, variable, or floating rate of interest, and must repay the amount borrowed, usually at the maturity of the security. Debt securities include corporate bonds, government securities (including Treasury securities), repurchase agreements, money market securities, mortgage and other asset-backed securities, loans and loan participations, and other securities, such as hybrids and synthetic securities, believed to have debt-like characteristics (e.g., securities classified as Tier 2 Regulatory capital, securities that rank above share capital in an insolvency waterfall, securities with maturity dates and non-cancellable interest payment structures).  Debt funds are funds (including mutual funds and ETFs) that invest at least 80% of assets in debt securities. Whether an underlying fund is included in the fund's 80% policy is determined at the time of investment and evaluated periodically thereafter. Derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the fund's 80% policy, consistent with the fund's investment policies and limitations with respect to investments in derivatives. Normally investing primarily in investment-grade debt securities (those of medium and high quality) of all types and repurchase agreements for those securities. Investing up to 30% of assets in high yield debt securities (also referred to as junk bonds) and emerging markets debt securities. Emerging markets include countries that have an emerging stock market as defined by MSCI, countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets that the Adviser identifies as having similar emerging markets characteristics. The Adviser considers a number of factors to determine whether an issuer is located in or tied economically to a particular country or region including: whether a third-party vendor has assigned a particular country or region classification to the issuer or included the issuer in an index representative of a particular country or region; the issuer's domicile, incorporation, and location of assets; whether the issuer derives at least 50% of its revenues from, or has at least 50% of its assets in, a particular country or region; the source of government guarantees (if any); and the primary trading market or listing exchange. Whether an issuer is located in or tied economically to a particular country can be determined under any of these factors. Investing in domestic and foreign issuers. Engaging in transactions that have a leveraging effect on the fund, including investments in derivatives - such as swaps (interest rate, total return, and credit default), options, forward contracts, and futures contracts - and forward-settling securities, to adjust the fund's risk exposure (including through hedging) and/or to create and adjust the fund's investment exposure. Implementing investment strategies by investing directly in securities through one or more managers (sub-advisers) or indirectly in securities through one or more other funds, referred to as underlying funds, which in turn invest directly in securities (as described below). The fund may allocate assets to affiliated or unaffiliated sub-advisers and funds but normally allocates assets primarily to Fidelity® funds and sub-advisers. Allocating assets among affiliated funds (i.e., Fidelity® funds, including mutual funds and ETFs), non-affiliated funds and non-affiliated ETFs. Using the Bloomberg U.S. Aggregate Bond Index as a guide in allocating assets among underlying funds and sub-advisers. Allocating assets among underlying funds and sub-advisers to attempt to diversify its portfolio in terms of different market sectors and maturities. Allocating assets among sub-advisers and underlying funds using proprietary fundamental and quantitative research, considering factors including, but not limited to, performance in different market environments, manager experience and investment style, management company infrastructure, costs, asset size, and portfolio turnover. Analyzing the credit quality of the issuer, the issuer's potential for success, the credit, currency and economic risks of the security and its issuer, security-specific features, current and potential future valuation, and trading opportunities to select investments. Pursuant to an exemptive order granted by the Securities and Exchange Commission (SEC), Strategic Advisers LLC (Strategic Advisers) is permitted, subject to the approval of the Board of Trustees, to enter into new or amended sub-advisory agreements with one or more unaffiliated sub-advisers without obtaining shareholder approval of such agreements.

Portfolio Turnover [Text Block] The fund will not incur transaction costs, such as commissions, when it buys and sells shares of affiliated mutual funds but may incur transaction costs when buying or selling non-affiliated funds and other types of securities (including Exchange Traded Funds (ETFs)) directly (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 operating expenses or in the example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 37 % of the average value of its portfolio.

Strategy [Heading] Principal Investment Strategies                                
Strategy Narrative [Text Block] Normally investing at least 80% of assets in U.S. common stocks and in shares of other U.S. common stock funds. Common stocks (including depositary receipts evidencing ownership of common stock) are a type of equity security that represents an ownership interest in an issuer. U.S. common stock funds are funds (including mutual funds and ETFs) that invest at least 80% of assets in U.S. common stocks. Whether an underlying fund is included in the fund's 80% policy is determined at the time of investment and evaluated periodically thereafter. The Adviser considers a number of factors to determine whether an issuer is located in or tied economically to a particular country or region including: whether a third-party vendor has assigned a particular country or region classification to the issuer or included the issuer in an index representative of a particular country or region; the issuer's domicile, incorporation, and location of assets; whether the issuer derives at least 50% of its revenues from, or has at least 50% of its assets in, a particular country or region; the source of government guarantees (if any); and the primary trading market or listing exchange. Whether an issuer is located in or tied economically to a particular country can be determined under any of these factors. Derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the fund's 80% policy, consistent with the fund's investment policies and limitations with respect to investments in derivatives. Investing in domestic and foreign issuers. Investing in either "growth" stocks or "value" stocks or both. Implementing investment strategies by investing directly in securities through one or more managers (sub-advisers) or indirectly in securities through one or more other funds, referred to as underlying funds, which in turn invest directly in securities (as described below). The fund may allocate assets to affiliated or unaffiliated sub-advisers and funds but normally allocates assets primarily to Fidelity® funds and sub-advisers. Allocating assets among affiliated funds (i.e., Fidelity® funds, including mutual funds and ETFs), non-affiliated funds and non-affiliated ETFs. Allocating assets among sub-advisers and underlying funds using proprietary fundamental and quantitative research, considering factors including, but not limited to, performance in different market environments, manager experience and investment style, management company infrastructure, costs, asset size, and portfolio turnover. Pursuant to an exemptive order granted by the Securities and Exchange Commission (SEC), Strategic Advisers LLC (Strategic Advisers) is permitted, subject to the approval of the Board of Trustees, to enter into new or amended sub-advisory agreements with one or more unaffiliated sub-advisers without obtaining shareholder approval of such agreements. Subject to oversight by the Board of Trustees, Strategic Advisers has the ultimate responsibility to oversee the fund's sub-advisers and recommend their hiring, termination, and replacement. In the event the Board of Trustees approves a sub-advisory agreement with a new unaffiliated sub-adviser, shareholders will be provided with information about the new sub-adviser and sub-advisory agreement .

During the most recent fiscal year, the fund's portfolio turnover rate was 53 % of the average value of its portfolio.

Strategy [Heading] Principal Investment Strategies                                
Strategy Narrative [Text Block] Normally investing at least 80% of assets in securities of issuers in emerging markets and other investments that are tied economically to emerging markets and in shares of other emerging markets equity funds. Emerging markets include countries that have an emerging stock market as defined by MSCI, countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets that the Adviser identifies as having similar emerging markets characteristics. Emerging markets funds are funds (including mutual funds and ETFs) that invest at least 80% of assets in securities of issuers in emerging markets and other investments that are tied economically to emerging markets. Whether an underlying fund is included in the fund's 80% policy is determined at the time of investment and evaluated periodically thereafter. The Adviser considers a number of factors to determine whether an issuer is located in or tied economically to a particular country or region including: whether a third-party vendor has assigned a particular country or region classification to the issuer or included the issuer in an index representative of a particular country or region; the issuer's domicile, incorporation, and location of assets; whether the issuer derives at least 50% of its revenues from, or has at least 50% of its assets in, a particular country or region; the source of government guarantees (if any); and the primary trading market or listing exchange. Whether an issuer is located in or tied economically to a particular country can be determined under any of these factors. Derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the fund's 80% policy, consistent with the fund's investment policies and limitations with respect to investments in derivatives. Normally investing primarily in equity securities. Allocating investments across different emerging markets countries. Implementing investment strategies by investing directly in securities through one or more managers (sub-advisers) or indirectly in securities through one or more other funds, referred to as underlying funds, which in turn invest directly in securities (as described below). The fund may allocate assets to affiliated or unaffiliated sub-advisers and funds but normally allocates assets primarily to Fidelity® funds and sub-advisers. Allocating assets among affiliated funds (i.e., Fidelity® funds, including mutual funds and ETFs), non-affiliated funds, non-affiliated ETFs, and closed-end funds. Allocating assets among underlying funds and sub-advisers to attempt to diversify its portfolio in terms of market capitalization, investment style, and geographic region. Allocating assets among sub-advisers and underlying funds using proprietary fundamental and quantitative research, considering factors including, but not limited to, performance in different market environments, manager experience and investment style, management company infrastructure, costs, asset size, and portfolio turnover. Pursuant to an exemptive order granted by the Securities and Exchange Commission (SEC), Strategic Advisers LLC (Strategic Advisers) is permitted, subject to the approval of the Board of Trustees, to enter into new or amended sub-advisory agreements with one or more unaffiliated sub-advisers without obtaining shareholder approval of such agreements. Subject to oversight by the Board of Trustees, Strategic Advisers has the ultimate responsibility to oversee the fund's sub-advisers and recommend their hiring, termination, and replacement. In the event the Board of Trustees approves a sub-advisory agreement with a new unaffiliated sub-adviser, shareholders will be provided with information about the new sub-adviser and sub-advisory agreement .

Strategy [Heading] Principal Investment Strategies                                
Strategy Narrative [Text Block] Normally investing at least 80% of assets in municipal securities whose interest is exempt from federal income tax. The municipal securities in which the fund invests are normally investment-grade (those of medium and high quality). Municipal debt securities are issued to raise money for a variety of public and private purposes, including general financing for state and local governments, financing for eligible non-profit organizations, or financing for a specific project or public facility. Municipal debt securities in which the fund invests include securities issued by U.S. territories and possessions, general obligation bonds of municipalities, local or state governments, project or revenue-specific bonds, or pre-refunded or escrowed bonds, municipal money market securities, and synthetic securities. Municipal securities usually pay a fixed, variable, or floating rate of interest, and must repay the amount borrowed, usually at the maturity of the security. Municipal debt securities also include shares of underlying funds (including mutual funds and ETFs) that invest at least 80% of assets in municipal debt securities. Investment grade securities in which the fund invests include securities or issuers rated at least BBB- or its equivalent by at least one nationally recognized statistical ratings organization (NRSRO), or, if unrated, determined by the Adviser to be of comparable quality. Derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the fund's 80% policy, consistent with the fund's investment policies and limitations with respect to investments in derivatives. Normally investing primarily in investment-grade municipal securities. Allocating assets across different market sectors and maturities. Potentially investing more than 25% of total assets in municipal securities that finance similar types of projects. Implementing investment strategies by investing directly in securities through one or more managers (sub-advisers) or indirectly in securities through one or more other funds, referred to as underlying funds, which in turn invest directly in securities (as described below). Allocating assets among affiliated funds (i.e., Fidelity® funds, including mutual funds and ETFs), non-affiliated funds and non-affiliated ETFs . Allocating assets among sub-advisers and underlying funds using proprietary fundamental and quantitative research, considering factors including, but not limited to, performance in different market environments, manager experience and investment style, management company infrastructure, costs, asset size, and portfolio turnover. Investing up to 30% in lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds). Analyzing the credit quality of the issuer, the issuer's potential for success, the credit, currency and economic risks of the security and its issuer, security-specific features, current and potential future valuation, and trading opportunities to select investments. Pursuant to an exemptive order granted by the Securities and Exchange Commission (SEC), Strategic Advisers LLC (Strategic Advisers) is permitted, subject to the approval of the Board of Trustees, to enter into new or amended sub-advisory agreements with one or more unaffiliated sub-advisers without obtaining shareholder approval of such agreements. Subject to oversight by the Board of Trustees, Strategic Advisers has the ultimate responsibility to oversee the fund's sub-advisers and recommend their hiring, termination, and replacement.

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 operating expenses or in the example, affect the fund's performance.
