VIMSIA is accredited by the Association Montessori Internationale (AMI) for the Primary through Upper Elementary Levels. Dr. Maria Montessori founded AMI in 1929. The organization is directed by an international board, and is supported by distinguished scholars and statesmen throughout the world.

AMI/USA was founded to conduct the business of AMI in the United States. The yearly dues we pay go to the United States Office in Rochester, New York. A portion is sent to the International headquarters in Amsterdam, The Netherlands.

AMI strictly regulates the standards to be met by member schools and teachers through their consultation program. They offer and run teacher-training programs, and organize national and international workshops and conferences. A team of specially trained consultants visits each school at least every three years. AMI is the reliable authority on authentic Montessori theory and practice, and since its inception, has been the coordinating agency of growth and development in Montessori.
