Review
Description
The sizes of classes are quite small, which I think is unique because it allows for more concentrated lessons and more one one-on-one teaching. The smallest class I've been to only had three other students. . .
There is an amazing family atmosphere at Knox that is unlike any other school I attended. I highly recommend the school for any parent looking for a boarding school because your child will be cared. . .
