What Parents Should Know
With an enrollment of 157 students, St Mary's School is a smaller school where families often find a close-knit community atmosphere. Smaller settings can mean more individual attention from teachers and staff, though they may offer fewer extracurricular options than larger schools.
With a student-teacher ratio of 5.6:1, St Mary's 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 Mary's School operates independently from the local public school district.

Private schools are not required to follow the same curriculum standards as public schools, which can be either an advantage or a consideration depending on your priorities.
