The Association Montessori Internationale (AMI) was established in 1929, by Dr Maria Montessori and her son Mario Montessori.

AMI is the recognised international authority on Montessori education and directs studies in affiliated teacher-training institutions around the world. During its long history, AMI has fostered the growth and development of Montessori education practices and standards through active work with member schools, teachers and educators. Regular study conferences of AMI have served as important milestones in the development of new practices and the exchange of insights which have grown out of the application of Montessori to widely differing lands and cultures.
