Among "All Schools", view the boarding schools with the lowest student:teacher ratio (2026).
Student:teacher ratios are only one indicator of student attention, as they merely indicate the number of adults on campus (in a teacher-related capacacity) relative to the number of students.
The student:teacher ratio is different than the average class size at a school and should not be confused as such.
