I agree with JaneSmith in that most people lump Montessori schools together and they are not all the same.
Couple of things I've noticed when I was researching them:
1. Here in our area they start at 18 months, not 3 years. So what Jane talks about sounds more regional. And this is all types of Montessori schools in our area.
2. We have ALOT of Montessori schools that are not certified but pretend to be. When you ask about it they go into a spill about all their teachers are, but when pushed on that not all of their teachers have the same type of cert. When I kept pushing they would finally admit that they were not certified but usually with an added comment about how it is in the works, yet some of the schools I called had been open for a long time.
So yes... They are not all the same.
