Our Faculty

Each Montessori classroom is staffed by two adults:  AMI certified Montessori teachers and classroom assistants who most often have a college degree.  Additional assistants prepare and supervise the outdoor environment, keeping the student/staff ratio of 3:1 and 13:1. These adults trust in the potential of each child to develop into a productive, caring adult and are eager to help each child discover his or her talents and capabilities.

The Tempe Montessori School is licensed by the Arizona Department of Health Services and recognized by the Association Montessori Internationale (AMI). AMI was founded in 1929 by Dr. Maria Montessori who intended that AMI serve two purposes: first, to protect her life’s work in its original integrity and completeness; and second, to guide its further development and application in the interests of all children.  From its international headquarters in Amsterdam, Holland, AMI has functioned as the source of authentic, complete Montessori training and as a center for continuing research and development. TMS is one of ten Montessori schools in Arizona accredited by AMI.
