What Parents Should Know

With a student-teacher ratio of 8:1, St Marys School offers a notably low ratio compared to the national average. This typically means smaller class sizes and more opportunities for one-on-one interaction between students and teachers.

As a private school, St Marys School operates independently from the local public school district.
