It depends a lot on the individual Montessori school. They can be very rigid, but not all are. We were lucky enough to find a school that met they child where he was. The head teacher (it was a very small school with only 3 teachers and a max of 23 students) told me after they first month there that he wanted to see how much ds could learn. I was okay with that, as he was a very good teacher and had already built a good relationship with ds. Ds was 2-almost-3 when he started the pre k program and went through pre k, k, and half of 1st grade in 2 years. Then they decided to retire and abandoned us. frown Now we homeschool, because public school wanted to put ds back in pre k due to his age.

All that was just to emphasize the point that it depends on the school. smile
