  • Among "All-Boys Schools", view the boarding schools with the smallest average class sizes (2018-19).
  • Keep in mind that small statistical differences in average class sizes between schools do not always indicate better student performance at one school or another.
  • Also keep in mind that boarding schools in general have smaller average class sizes than public schools - even for schools with larger class sizes, a "large" class in a boarding school would still often be considered small by public school standards which often have class sizes of 20 students.
