Is this an accredited Montessori school?

AMI/USA Affiliated

AMI/USA is the United States affiliate of Association Montessori Internationale. Affiliation signals a connection to the AMI network; it is a different (and less exhaustive) standing than full AMI Recognition.

Verify directly at amiusa.org.

Accreditation is not the same as an operating licence. A provincial/state child care licence or private school registration only confirms a school is legally allowed to operate — it says nothing about whether the teaching method is Montessori.

Teacher credentials matter too. Ask how many lead teachers hold AMI, AMS, or MACTE-accredited teacher training — a strong signal independent of the school's own accreditation status.
