NAMTA's purpose is to maintain Montessori traditions, and at the same time, to be on the cutting edge of innovative education. Accordingly, we provide the medium for study, interpretation, and improvement of Montessori education.
The two major organizations offering Montessori training in the United States are the Association Montessori Internationale (AMI, with a U.S. branch office called AMI-USA) and the American Montessori Society (AMS). Most training centers require a bachelor's degree for admission. Training ranges from 200 to 600 pre-service contact hours and covers principles of child development and Montessori philosophy as well as specific uses of the Montessori classroom materials. Montessori training centers can be found across North America and around the world.
