What are the criteria for admission? How do we apply?

Principia School welcomes students from around the world who are actively interested in Christian Science and regularly attend a Christian Science Sunday School or Children’s Room.

Procedures for applying to the different levels vary slightly, but in general, we require:

  • Three academic references for applicants from grades 6 through 12
  • Two Christian Science references
  • Official copies of grades and test scores, where applicable

Please review our online application process and requirements. For international students, additional application requirements apply.

What does it cost to attend, and is there financial assistance?

Through the generosity of donors, Principia School is able to set tuition rates well below actual cost and also offer substantial financial assistance and scholarships to help make a Principia education affordable for most families.

Annual tuition and fees start at $3,500 for Early Childhood programs and go to $16,050 for Upper School students. (Boarding costs are additional.) Refer to our schedule of tuition and costs for more information.

Ninety-four percent of enrolled families receive financial aid. Find out how affordable a Principia education is.

Is before- and/or afterschool care available?

Yes! We have a wonderful before- and afterschool program for children from kindergarten through grade 5.

Before-school care is available from 7:00–8:00 a.m. and afterschool care is available from 3:30–5:45 p.m. Periodically, after-school enrichment classes (such as acting or chess) are offered for an additional fee. Get more details here.

During the summers we also offer the Summertime Discovery day-camp program for children between the ages of four and 11. Find out more about the activities and options for attendance. 

Do students use technology and have access to computers and the Internet?

Yes. As a part of our commitment to preparing learners for the promise and potential of the 21st century, Principia incorporates wireless and electronic technology into the curriculum in various ways. Starting in Lower School, students have opportunities to use laptops and iPads in class and become proficient in keyboarding. The Lower and Middle School library also has wireless access, which students may use for supervised Internet research.

In Middle School and Upper School, each student receives a MacbookAir laptop for use at home and at school during the academic year. This tool enables teachers and students to deepen and extend learning opportunities. Students are required to attend training sessions that include an explanation of the program, discussion of Principia’s Technology Use Principles, an overview of the hardware and software on the tablet, and important information about caring for the tablet. In order to use this tool most effectively, access to the Internet at home is expected as assignments often incorporate Internet use.

How are parents involved in School activities?

The Principia Parents Association is one of the main vehicles for parental involvement—but not the only one! At all levels of the School, parents are invited to participate in a range of classroom events and activities as well as in athletic programs. Local, St. Louis-based parents often serve as hosts for boarding students during holiday periods.

Each semester, scheduled parent conferences at the Lower and Middle Schools allow parents, their student/s, and teachers to discuss and evaluate progress. At the Upper School, parents are free to schedule individual meetings with teachers or academic counselors at any time.

What’s the boarding experience like?

The Principia Middle and Upper School boarding experience is one of a kind—an opportunity for young adults to obtain a high-quality education away from home, while experiencing an expanded sense of family, responsibility, and independence under the guidance of our committed Home Department. We invite you to hear what students have to share about the benefits of boarding, and learn more about how it works.

What happens if a student is unwell or needs physical care?

Christian Science care is provided at Campus House, our student-focused Christian Science nursing facility. In a quiet, healing atmosphere, Journal-listed Christian Science nurses are available 24 hours a day, seven days a week during the academic year. Although overnight rooms are a provision for boarding students only, day-student families are welcome to visit or call any time with questions or requests for assistance.

Each level of the School also has a designated “quiet room” where students may go to quietly rest, pray, or contact a Christian Science practitioner when there’s a need. Christian Science study materials are available in each of these restful locations.
