What Parents Should Know

St Augustin Catholic School runs 26.7:1 students to teachers, above the national average. That often means bigger classes. Ask how the school supports kids who need extra help, and whether there are teaching assistants or small-group time.

St Augustin Catholic 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.
