Largest boarding schools

Schools with the most total enrolment

Parents may feel that bigger boarding schools offer certain advantages. Certainly, a larger student body is likely to be more diverse, offering your son or daughter exposure to classmates and dormmates from the greatest variety of backgrounds. That said, there are advantages to smaller schools, too, of course.

Throughout our site, we encourage skepticism of any school rankings. Read expert advice. For the sake of interest, though, below is a list that ranks boarding schools by overall enrollment.
