About Principia School
Principia School is a private school in St. Louis, MO. Principia School serves approximately 15 students, and covers grades Pre-K-12th, and has a 0.5:1 student-teacher ratio.
MySchoolScout does not publish a rating for this profile because there is not enough verified data to rate it fairly. Based on limited data: 0% component coverage.
What Parents Should Know
At 15 students, Principia School is on the smaller side. That usually buys more individual attention and teachers who know every kid by name, with the trade-off of fewer electives and extracurriculars than a larger school can staff. Ask what activities it actually offers.
At 0.5:1 students to teachers, Principia School sits well below the national average. Smaller classes like that usually mean more one-on-one time between students and teachers.
Principia School is private, so it runs independently of the local district and sets its own curriculum. That freedom cuts both ways depending on what you want for your child. If you're considering it, start with the practical questions: tuition, financial aid, and how admissions work.

Why doesn't this school have a score?
We don't have enough verified data to rate this school fairly. Private schools in MO aren't required to report standardized test scores to the state, which limits the data available for our rating model.
Our rating model requires at least 2 of 4 data components (academics, student progress, college readiness, and resources) to generate a meaningful score. Schools below this threshold receive a Limited Profile to avoid misleading ratings.
