Among "All-Boys Schools", view the boarding schools with the highest percentage of boarding students (2025-26).
The percentage of boarding students at a school is only an indicator of the balance between boarding students and day students.
Many boarding schools with a smaller percentage of boarders still have very strong boarding programs, so it helps to look individually at each school.
