Is this an accredited Montessori school?

AMS Accredited

American Montessori Society (AMS) Accredited is the Society's top standing — the school has passed a multi-year self-study and on-site peer review covering curriculum, teacher training, and facilities against AMS's full standards.

Verify directly at amshq.org/schools using the school's name and city.

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.
