Sounds like montissori would be great for your child! My son was in one for a little while, it didn't work for us because he is the type of person who has to have everything in control {not like me at all} I spent alot of time at the school with my son and I did notice it was very low pressure. If a child did not want to be in circle time they could find some quiet "work" to do. Just make sure like any child care center, you should look at the reports from the two times a year the state comes in. You should be able to get a 3 or 6 year history on everything they have seen.
