Smallest Average Class Size

Among "All-Girls Schools", view the boarding schools with the smallest average class sizes (2025).

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.
