Smallest Student Body

Among "All-Girls Schools", view the boarding schools with the smallest student bodies (2025-26).
School size comparisons are based on overall population of the school, not the number of boarding students at the school.
The balance between boarders and day students can also be another factor to consider when looking at school size.
