Faculty and Staff
We are proud of our teachers and staff longevity, with our ten-year average tenure. Country Montessori School strongly supports staff development and promotion from within.
As a certified Montessori School, our teachers must also be formally trained. We sponsor the majority of our teaching staff to obtain the necessary credentials.
Montessori Teaching Credentials
Teachers receive their Montessori teaching credentials from a Montessori Accredited Center of Teaching Education organization such as AMS (American Montessori Society) or AMI (American Montessori Internationale).
Montessori teachers study a rigorous curriculum of child development and Montessori philosophy. AMS Montessori credentialing requires a 9-month practicum and a series of written and oral exams. A Montessori-credentialed teacher is trained to recognize a child’s readiness according to age, ability, and interest in a specific lesson and is prepared to guide individual progress.
All lead teachers at Country Montessori School are Montessori-credentialed for their teaching programs. Some of our teachers and Classroom Assistants are in training and completing their practicum under the guidance of an experienced teacher. All lead elementary teachers must have a minimum college education of a Bachelor’s degree.
