What Parents Should Know

With an enrollment of 165 students, Assumption 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.

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