Non-Discrimination Policy & DEI

TMS does not discriminate on the basis of race, color, religion, national origin, gender, sexual orientation, age or disability in its programs, activities or employment practices.

TMS believes that full educational excellence is best accomplished within a diverse community. We are committed to creating an environment that fosters peace, embraces diversity and encourages a diverse population. Our goal is to promote inclusion and collaboration, supporting an environment of openness where the exchange of ideas is appreciated and encouraged.

Multicultural education is an integral part of the Montessori philosophy. Our curriculum respects the individuality of each child, creates a community of cooperation and nurtures a sense of wonder and curiosity about our differences. We honor and actively explore the varied backgrounds and cultures in the world. Students are encouraged to appreciate different perspectives, identify and reject stereotypes and prejudices, and work for equality and justice within the school and the world.

TMS enjoys a diverse community of students, families and staff, and supports differences of gender, race, religion, family structure, socio-economic level, age, sexual orientation, and learning style. We strive to maintain a collaborative environment rooted from the sharing of experiences, ideas and unique qualities that each of our members brings to the school. Our goal is that through these efforts, each member of our community will feel valued and understood.
