Accreditation "Montessori" has no trademark protection, so accreditation from a real body is the closest thing to a quality check.Source: Accrediting body's own directory
Portland Montessori Collaborative (pdxMC) is a Montessori school located in Portland, Oregon.
This school hasn't published tuition — contact them directly, or help other families by sharing what you know.
AMS Member
AMS Member means the school has joined the American Montessori Society and affirms alignment with Montessori principles, but has not (yet) completed AMS's formal accreditation review — membership alone doesn't verify classroom practice.
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.
