Accreditations

Green Tree has officially earned full accreditation from the American Montessori Society (AMS) — making us only the second school in the entire state of Missouri to achieve this distinction.

AMS accreditation is one of the most rigorous recognitions in Montessori education, and earning it validates what we have always believed: that this is a true, authentic Montessori school. In their letter to us, AMS wrote:

“We acknowledge the dedication and commitment you made in achieving accreditation. Your continued commitment to upholding the highest standards of Montessori education and working toward continuous school improvement is to be commended. The AMS community joins me in congratulating you on this tremendous endeavor.”
