What Parents Should Know

With an enrollment of 91 students, Cedar River Montessori 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 7.4:1, Cedar River Montessori 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, Cedar River Montessori School operates independently from the local public school district.
