Teachers are the most important factor in student achievement. All of our full time teachers are American Montessori Society certified or working towards Montessori certification. All our teachers have at least one bachelor’s degree with most having at least one master’s degree and many holding a PhD. CMS is an AMS affiliate school, and is working towards full AMS Accreditation. We are proud of the cultural and geographic diversity of our teaching staff, which brings us a truly global educational environment. Our average student-teacher ratio is 11 to 1.
