Teacher came to school smelling like marijuana last year. The school immediately sent her home but not before the kids found out about it which lead to unexpected conversation with my daughter. She was not happy at the school and we pulled her out this year. While the arts and music is top notch I feel the math and other core areas are lacking

As an international student, Principia has provided a vast amount of opportunities; the teachers are very welcoming, and the dorm logistics are very supportive for all the students.

I loved the welcoming environment. The community in general is warm and you can feel part of it since day one. The campus is very pretty and the facilities are top. One thing I would like to see changed is the food, it is not terrible but it can improve.

Excellent. There has been drastic improvement in my child’s grades and overall character to be a well rounded individual. The boarding system is excellent and adds to the expectations of responsibility by the kids.
