In my experience at Principia, the culture here fosters every aspect of a character, rather it be spritually, academically, physically, and emotionally, contributing to creating a generation full of global citizens, and change makers.
3/31/2026
As an international student, I love Principia. It's a place where the faculty and everyone here genuinely show love and kindness. Everywhere you go, there's a sense of care and community—it's truly an amazing place to learn and grow. The sports help us build character and grit, the academics are outstanding, and the teachers truly care and support us as we grow.

My experience with Principia has been exceptional. I have learned so many new things, and Principia has given me an experience that I would not be able to have with any other school. Principia has allowed me to make many different connections and helped me advance as a student, athlete, and person all at the same time.

this is the best school ive ever been to. Bring your kids here, i know its expensive, but i swear its worth it.
11/20/2020
Relocating to STL for our kids to attend Principia was the best gift we could give our children. Our youngest (Preschool) exudes an endless stream of joy and happiness. She overflows with love for her teachers, her new friends, and her experience. The transformation we’ve seen in our eldest (gr. 4)...

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.
6/18/2020
Excellent. My children had opportunities to play sports, receive great instruction in class and in sports, meet students from all over the world, travel to Israel for Bible class, and grow as individuals.
