Professional Affiliations and Recognition

Association Montessori Internationale



Maria Montessori founded AMI in 1929 to protect and further her educational work. AMI operates teacher training centers worldwide and, through its USA affiliate , accredits Montessori schools though a program of internationally recognized standards and regular consultation.

All of Sunstone’s teachers are AMI trained. AMI teacher training is an intensive full-time one year course in human development, Montessori philosophy and practice, and classroom curriculum. Most training centers offer graduate level credit with an affiliated university, and many trainees concurrently earn a Masters in Education during their training.

The term ‘Montessori’ is not trademarked or copyrighted, and anyone can use it. AMI training and accreditation is the oldest and most widely recognized standard, as well as the only standard developed by Dr. Montessori herself.
