The word “Montessori” is not trademarked, so a wide range of practices can be found in schools with Montessori in their names. Accreditation establishes a consistency of standards and the preservation of the Montessori philosophy of education. It also holds schools accountable to parents and to the larger community. There are different accreditation programs in the US.
To receive the AMI certificate of recognition indicating that a level is fully recognized, 100% of the lead teachers at that level are AMI trained and all of the AMI standards must be achieved.
To qualify for the Affiliated status, two out of three classrooms or three out of four classrooms at that level or multiples thereof, are led by AMI teachers. The level meets all other AMI standards.
To qualify for the Associated status, 50% of the lead teachers must hold an AMI diploma. The Associated status is also a transitional category for schools that are in the process of developing programs that meet all of the AMI standards.
