Risk Return Abstract rr_RiskReturnAbstract  
Risk/Return [Heading] rr_RiskReturnHeading <span style="color:#000000;font-family:Arial;font-size:13pt;font-weight:bold;">ETF Summary</span>
Objective [Heading] rr_ObjectiveHeading <span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;">Investment Objective</span>
Objective, Primary [Text Block] rr_ObjectivePrimaryTextBlock The Fund seeks to track the performance of a broad, market-weighted corporate bond index.
Expense [Heading] rr_ExpenseHeading <span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;">Fees and Expenses</span>
Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock The following tables describe the fees and expenses you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and example below.

Operating Expenses Caption [Text] rr_OperatingExpensesCaption <span style="color:#000000;font-family:Arial;font-size:8.5pt;font-weight:bold;">Annual Fund Operating Expenses</span> <br/><span style="color:#000000;font-family:Arial;font-size:8.5pt;">(Expenses that you pay each year as a percentage of the value of your investment)</span>
Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading <span style="color:#000000;font-family:Arial;font-size:9.5pt;">Portfolio Turnover</span>
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock The Fund may pay 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 more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 8% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 8.00%
Expense Example [Heading] rr_ExpenseExampleHeading <span style="color:#000000;font-family:Arial;font-size:9.5pt;">Example</span>
Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock The following example is intended to help you compare the cost of investing in the Fund (based on the fees and expenses of the acquired funds) with the cost of investing in other funds. It illustrates the hypothetical expenses that you would incur over various periods if you were to invest $10,000 in the Fund’s shares. This example assumes that the Fund provides a return of 5% each year and that total annual fund operating expenses (of the Fund and its underlying funds) remain as stated in the preceding table. You would incur these hypothetical expenses whether or not you were to sell your shares at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading] rr_StrategyHeading <span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;">Principal Investment Strategies</span>
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock The Fund is a fund of funds and employs an indexing investment approach designed to track the performance of the Bloomberg U.S. Corporate Bond Index (the index), which measures the investment-grade, fixed-rate, taxable corporate bond market. The Index includes U.S. dollar-denominated securities that are publicly issued by industrial, utility, and financial issuers. The Fund intends to obtain its exposure to the bonds held in the Index by investing all, or substantially all, of its assets in a mix of Vanguard bond index ETFs (underlying funds), rather than in individual securities held in the Index. The underlying funds are Vanguard Short-Term Corporate Bond ETF, Vanguard Intermediate-Term Corporate Bond ETF, and Vanguard Long-Term Corporate Bond ETF, which seek to track the performance of the Bloomberg U.S. 1–5 Year Corporate Bond Index, the Bloomberg U.S. 5–10 Year Corporate Bond Index, and the Bloomberg U.S. 10+ Year Corporate Bond Index, respectively. The underlying funds’ bond holdings are a diversified mix of short-, intermediate-, and long-term investment-grade corporate bonds. Each of the underlying funds seeks to track the performance of an index that represents a subset of the Bloomberg U.S. Corporate Bond Index. Together, the three indexes tracked by the underlying funds comprise the Fund’s target index.
Risk [Heading] rr_RiskHeading <span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;">Principal Risks</span>
Risk [Text Block] rr_RiskTextBlock • Interest rate risk, which is the chance that bond prices overall will decline because of rising interest rates. Interest rate risk should be moderate for the Fund.• Credit risk, which is the chance that a bond issuer will fail to pay interest or principal in a timely manner or that negative perceptions of the issuer’s ability to make such payments will cause the price of that bond to decline. Credit risk should be moderate for the Fund.• Income risk, which is the chance that a fund’s income will decline because of falling interest rates.• Liquidity risk, which is the chance that a fund may not be able to sell a security in a timely manner at a desired price.• Index-related risks. The Fund is subject to risks associated with index investing, which include passive management risk, tracking error risk, and index provider risk. Passive management risk is the chance that the Fund’s use of an indexing strategy will negatively impact the Fund’s performance. Because the Fund seeks to track the performance of its target index regardless of how that index is performing, the Fund’s performance may be lower than it would be if the Fund were actively managed. Tracking error risk is the chance that the Fund’s performance will deviate from the performance of its target index. Tracking error risk may be heightened during times of increased market volatility or under other unusual market conditions. Index provider risk is the chance that the Fund will be negatively impacted by changes or errors made by the index provider. Any gains, losses, or costs associated with or resulting from an error made by the index provider will generally be borne by the Fund and, as a result, the Fund’s shareholders.• Index sampling risk, which is the chance that the securities selected for a fund, in the aggregate, will not provide investment performance matching that of a fund’s target index.• Underlying fund risk. Because the Fund invests substantially all of its assets in underlying Vanguard funds, it is subject to underlying fund risk. This means that the Fund is exposed to all of the risks associated with the investment strategies and policies of the underlying Vanguard funds, including the risk that the underlying funds will not meet their investment objectives.Because the Fund is an exchange-traded fund (ETF) and the Fund’s shares are traded on an exchange, the Fund is subject to additional risks:• The Fund’s ETF Shares are listed for trading on Nasdaq and are bought and sold on the secondary market at market prices. Although it is expected that the market price of an ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly. Thus, you may pay more or less than NAV when you buy ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares. The market price of the Fund’s ETF Shares may be affected by the market prices of the underlying funds’ ETF Shares.• Although the Fund’s and underlying funds’ ETF Shares are listed for trading on Nasdaq, it is possible that an active trading market may not be maintained, which could increase the Fund’s risks as disclosed in this prospectus.• Trading of the Fund’s and underlying funds’ ETF Shares may be halted by the activation of individual or marketwide trading halts (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of the Fund’s and underlying funds’ ETF Shares may also be halted if (1) the shares are delisted from Nasdaq without first being listed on another exchange or (2) Nasdaq officials determine that such action is appropriate in the interest of a fair and orderly market or for the protection of investors. If trading of an underlying fund’s shares is halted, the Fund may not be able to purchase or dispose of underlying fund shares in a timely manner, which could increase the Fund’s risks as disclosed in this prospectus.
