Is this an accredited Montessori school?
No accreditation or membership from a recognized Montessori body (AMI, AMS, or Montessori Canada) is on file for this listing. Because "Montessori" isn't a protected trademark in the US or Canada — a 1967 USPTO ruling put the term in the public domain — any school can use the name regardless of how closely it follows the method. That doesn't mean this school isn't authentically Montessori; it means accreditation status isn't the way to check here. Ask the school directly about their teacher training (look for AMI or AMS-trained staff) and ask to observe a classroom work cycle.
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.
