| Factors Affecting Performance [Text Block] | How did the Fund perform during the reporting period? For the 12 months ended October 31, 2024, the Fund underperformed its benchmark, the Conservative Growth Composite Index. This was largely because of differences in the price of international equity securities used by the Fund to calculate its net asset value and the quoted published prices for the same securities. This practice is known as fair-value pricing. The Fund also diverged from the index due to tax withholding differences that were tied to investments in international equity securities. Global economic growth appeared relatively stable at around 3% during the period, and U.S. recession fears faded. With inflation continuing to moderate across much of the world, major central banks including the European Central Bank, the Bank of England, and the U.S. Federal Reserve began lowering policy rates. Global stocks posted very strong returns. As a fund of funds, the Fund provides a broadly diversified portfolio in a single fund. Its four underlying funds posted returns as follows: U.S. stocks about 38%, U.S. bonds about 10%, international stocks about 23%, and international bonds more than 9%. |

| Factors Affecting Performance [Text Block] | How did the Fund perform during the reporting period? For the 12 months ended October 31, 2024, the Fund performed roughly in line with its benchmark, the STAR Composite Index. Global economic growth appeared relatively stable at around 3% during the period. With inflation continuing to moderate across much of the world, major central banks including the European Central Bank, the Bank of England, and the U.S. Federal Reserve began lowering policy rates. U.S. stocks and bonds both posted very strong returns. As a fund of funds, the Fund reflects the results of 10 underlying actively managed Vanguard funds invested in U.S. stocks, non-U.S. stocks, and U.S. bonds. Of those, stock funds made up about 63% of the Fund’s assets. Total returns for the 10 underlying funds ranged from about 9% for Vanguard Short-Term Investment-Grade Fund to about 47% for Vanguard U.S. Growth Fund. Vanguard Long-Term Investment-Grade Fund delivered the highest return (about 18%) among STAR’s bond funds, while Vanguard International Value Fund reported the lowest return (about 19%) among the stock funds. |

| Factors Affecting Performance [Text Block] | How did the Fund perform during the reporting period? For the 12 months ended October 31, 2024, the Fund underperformed its benchmark index, largely because of differences in the prices of securities used by the Fund to calculate its net asset value and the quoted published prices for the same securities. This practice is known as fair-value pricing. Global economic growth appeared relatively stable at around 3% during the period, and U.S. recession fears faded. With inflation continuing to moderate across much of the world, major central banks including the European Central Bank, the Bank of England, and the U.S. Federal Reserve began lowering policy rates. Global stocks posted very strong returns. The Fund’s benchmark posted solid results across all regions and sectors. Of the two largest regions in the benchmark by weight, emerging markets posted the strongest returns; given its heavier weighting in the index, however, Europe contributed most to the Fund’s returns. By sector, financials, industrials, and technology contributed most. |
