Among "All Schools," view the twenty boarding schools with the "highest percentage of boarding students." First, some important notes:
- 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.
