By contrast South Kent School is an example of a small school with 150 students. What do Exeter and South Kent have in common? A low student to faculty ratio. Typically private schools have student-faculty ratios in a range of 10:1. This is the genius of private schools. This is what you are really paying for when you send your child to private school: the personal attention to her learning needs.
Low student to faculty ratio is another way of saying that the class sizes are small. That is a good thing. You see, in a small school your daughter cannot escape and hide from view like she can in a large public school with large class sizes. When she sits around a Harkness table with fourteen other students and the teacher in the middle, there's no hiding anything.
As a result of small classes, teachers are able to dig deeply into the material. They are able to explore the sidebars and cement the fundamentals in place. (Parenthetically, it is a very satisfying feeling to be able to truly teach as one can do in a private school, as opposed to playing traffic cop as one does in most public schools.)
Small is indeed good!
