There is accreditation. You can't stop someone from saying they are Montessori, but only accredited schools that follow the model and have trained teachers can claim to be accredited, which is a differentiator.
One of my kids went to play-based preschool and one did Montessori. They are both very bright and learned to read early, but no question the one in Montessori learned more, across many dimensions (math, geography, practical life, science).
