| Performance Narrative [Text Block] | The following bar chart and table show the Fund’s historical performance and are intended to help you understand the risks of investing in the Fund. The Fund has adopted the performance of the Baillie Gifford Positive Change Equities Fund (the predecessor fund), the performance predecessor to the Fund, as a result of a reorganization of the predecessor fund into the Fund on July 18, 2022 (the Reorganization). The predecessor fund was managed using investment policies, objectives, guidelines and restrictions that were substantially similar to those of the Fund. Prior to the Reorganization, the Fund had not yet commenced operations. The bar chart shows how the performance of the Investor shares of the Fund has varied from one calendar year to another over the periods shown. The table shows how the average annual total returns of the Fund compare with those of a broad-based securities market index. MSCI ACWI Index returns are adjusted for withholding taxes. Keep in mind that the Fund’s (and the predecessor fund’s) past performance (before and after taxes) does not indicate how the Fund will perform in the future.The returns shown for periods through July 18, 2022, are those of the predecessor fund’s Institutional Class shares. The Institutional Class and Class K shares of the predecessor fund were reorganized into the Investor shares of the Fund on July 18, 2022. Returns of the Fund’s Investor shares will be different than returns of the predecessor fund’s Institutional Class or Class K shares, as they have different expenses.
