  1. The IMAC accrediting agency is for accreditation of Montessori teacher education, NOT schools for children. IMS has a program of recognizing Montessori schools, based on its criteria to assure their commitment to the IMS philosophy of Montessori teaching committed to laws of nature.


  2. Goodsite.

    The Montessori Foundation and the International Montessori Council are independent organizations, not affiliated with AMS.
