Of these, about 20% are affiliated with the two major accrediting organizations. Association Montessori Internationale (AMI) (http://www.montessori-ami.org/) promotes the study, application, and propagation of Montessori's (original) ideas and principles for education and human development. The American Montessori Society (AMS) (http://www.amshq.org) supports Montessori education in the context of contemporary American culture (Loeffler, 1992). The Web sites provide information about program history, philosophy, accreditation, teacher training, and published resources. The AMI Web site provides a map that gives a good picture of the Montessori movement worldwide.
