Lowest Teacher:Student Ratio
Among "All Schools," view the twenty boarding schools with the "lowest teacher:student ratio." First, some important notes:


  • Teacher:student 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 teacher:student ratio is different than the average class size at a school and should not be confused as such.
