The American Montessori Society (AMS) is the foremost advocate for quality Montessori education, an innovative, child-centered approach to learning. AMS sets the high professional standards that inform Montessori education as practiced in AMS-accredited schools and taught in AMS-affiliated teacher education programs.

A not-for-profit organization based in New York City, with nearly 13,000 members worldwide, AMS is also a hub of all things Montessori: an information center for its members, the media, and the public; a voice in the public policy arena; and a mobilizing force for the global Montessori community, through support services, research, and professional development events.
