Principia School

From infancy through grade 12, your child’s educational journey is guided by those who believe in boundless possibility. Beyond a college-prep day and boarding school in St. Louis, Principia is founded upon Christian Science principles that see students as limitless and divinely whole. Here, our students grow through character education and experiential learning to uncover natural strengths, critical thinking skills, and limitless potential. Above all, our students learn what it means to live with Purpose. You’ll see the difference everywhere you look—from the creativity and future-ready learning in and out of the classroom, to the air of inclusivity and sportsmanship.
