I learned and grew a lot at the Principia. The people at the school taught me the qualities of grit, leadership, and character. I had the opportunity to serve on student government in several positions where I truly felt loved and supported by the faculty and my community. I learned how to work hard for good results, and I often found myself doing so, but I was always supported by my peers and house moms. Because I decided to give it my all, school was very difficult for me at some points, and I worked harder than most. However, the outcome was worth it, and looking back I learned a lot about myself and hard work. I also learned what is important to me throughout the experience. I gained wonderful relationships from the Principia, and that is why I decided to go to the Principia College and continue my growth!

The academics at Prin are pretty awful, especially for kids that have gone to a good school in the past. There’s such little pressure put on them and kids do not care, so even the smart kids lose motivation. A lot of this is related to teachers, the few good ones are Moser and Marston, but many of the other teachers aren’t smart or good at teaching. Prin requires CS teachers, which really makes academics suffer due to such little options. To specify, I had a teacher who so many kids were scared of. On the first day he would open by saying, “Don’t be alarmed if I ever start massaging your neck or shoulders while you’re working, it’s what I do to my kids and I can’t help it.” So unprofessional. Prin tried to correct him, but he never improved, and they couldn’t fire him because there’s few CS teachers. Overall, there’s little motivation for college, success, and in general, which needs to be changed.
I love the like-minded atmosphere Prin creates. It really made me feel at home when I first enrolled even though it was halfway through the school year. The faculty and staff make it a point to be sure that everyone is taught to be responsible and hardworking.
One thing I think could be improved though is making sure every department is treated equally. As a student heavily involved in the performing arts program I often felt that sports would get a lot more recognition than the arts did. My friend and I went to a lot of the basketball and football games but when it came to our few performances of the year there was usually not the same amount of advertising for, and so less turn out, at these performances.
Overall though I have loved my time at Prin and have made some incredible friendships as well as learned a lot.
