Let me add some additional context here (source: twins in a private Montessori in a central EU country) a) Montessori Schools vary usually - not only from country to country, also not only from state to state, but also within Cities b) There are networks per each conutry, but you may join as school if you do offer different things than other schools in the same network c) Within Montessori, there are a lot of "custom" approaches which are, at least in this country, usually discussed with the local government/educational gov d) the comments with selection according to higher socio economical levels is a hard fact, at least in this country, since Montessori schools always demand some type of payment, depending on the income of the parents (on top of that they get usually partial funding from the local municipal/gov per school-people). At my kids school, 98% of parents are in a "good six digit range" (while the average salary in this country is mid. five figures, like ~49000) e) my kids school is great, so i can only speak for this locatoin with their specific Montessori implementation: It is a school i wished i could have attended when i was young. Its great: Their building is quite fresh (note: there are some "parental hours" per year where YOU have to take care of the building for YOUR kids on YOUR OWN with the OTHER parents, this is 40h per parent-person in this location), they have a "everything-is-working-facility", not only rest rooms but also working IT equipment etc. (for which i have a special eye as HN user ;-) ), last years the built an additonal level on top of the building to install a free-range-roof-top and tennis area Maybe this helps (-:
