How to Apply

Be Known. Be Challenged. Belong.

At The Knox School, being known makes all the difference.

Our small, close-knit community offers something increasingly rare: a school where teachers know their students as individuals, challenge them academically, and support their growth both inside and outside the classroom. Students are encouraged to think independently, explore their interests, take on new challenges, and contribute to a globally diverse community where everyone has a place.

Come discover what it means to be known, challenged, and part of Knox.

We look forward to getting to know you and helping you take the next step toward joining our community.
