Principia School Hosts Fourth Annual National High School Mediation Tournament. Mediation offers high school students opportunities to develop as problem solvers and peacemakers.

This fall’s Upper School Reunion brought more than 300 alumni and guests to campus for a memorable celebration spanning the generations.

Principia School is embarking on its seventh year as a partner in the St. Louis Box Turtle Project, a study dedicated to the conservation and health of the three-toed box turtle. Principia’s role is to track the movement of the native species in a suburban environment, using the School’s 360-acre campus as a testing ground. While Principia’s part in the study may seem small, the data plays a big role in the Zoo’s turtle conservation program, and Principia students have had a direct hand in the process.

Week-long character trips take students to unique destinations to build essential life skills 

St. Louis, MO—Each year, Principia Upper School students embark on a week of outdoor expeditions designed to foster teamwork and collaboration skills while cultivating confident leaders.  Freshmen, sophomores, and juniors participate in activities such as canoeing, sailing, or touring new cities. Seniors travel to Michigan for their annual Senior Retreat to build outdoor and wilderness skills while bonding as a class and learning what it means to be an effective leader. The trips provide students with impactful experiences and profound lessons that reinforce Principia School’s character education program. 

On May 21, Principia Upper School students, parents, faculty and staff, and community members gathered to honor the class of 2023. The event celebrated the accomplishments of the 36 graduating seniors, highlighted their diverse backgrounds, and expressed gratitude for  the faculty members who played a monumental role in their education.
