There are approximately 220 students at Cambridge Montessori School. We have three Toddler classrooms (21 months-3 years), five Primary classrooms (3-6 years), four elementary classrooms (two 6-9 years, two 9-12 years) and one Middle School classroom.
Our families come from Cambridge, Arlington, Belmont, Boston, Somerville, Medford and many other surrounding towns. CMS takes pride in its international community. Over twenty different languages are spoken by our families and we look forward to having families share their cultural celebrations with our classrooms.
