What Parents Should Know
At 39 students, Cornerstone 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 8.5:1 students to teachers, Cornerstone School sits well below the national average. Smaller classes like that usually mean more one-on-one time between students and teachers.
Cornerstone 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.
