Largest Endowments

Among "All-Girls Schools", view the boarding schools with the largest endowments (2026).
Boarding schools that have larger students bodies or older histories are more likely to have larger endowments than other schools (since they have had more alumni over the years to donate funds).
Schools with lower endowments still often have excellent facilities and resources for students, but simply have not yet had the time or alumni base to build up endowments equivalent to older, larger schools.
Endowment per student is another metric for comparing endowments between schools of different size.
Smaller schools can often have a larger endowment per student figure than larger schools.
