Don't know if it's still there, but he was the perfect Montessori child. After we moved to Kansas, I again sent him to a Montessori school. In both places the teachers told me he was the first kid they'd ever known who actually fit the Montessori model.
I slightly (but only slightly) regret sending him to a regular public school starting in 1st grade. I did so because any number of people told me, that if I were planning on sending him to regular public school first grade would be better than waiting a year or two. As it turned out, half way through third grade we moved him from an excellent public school to an even better independent school.
About the only problem I see with Montessori is that they don't seem to hang on to the kids after the first few years. I would love to have been able to send my kid to Montessori through at least sixth grade. But the Montessori school in Kansas City -- where we moved to from Boulder -- only went through 6th grade, and after about 1st or 2nd grade had maybe five or so students per grade level. The son I'm talking about is now 25, so things may be very different by now.
I will say that I totally loved the Boulder Montessori school, and probably would have kept that child there as long as possible, had we stayed.
The advice I was given, that moving my child into regular public school at first grade, while well intended, may not have been such good advice. Clearly, you will need to think very hard about the specific children involved, but kids make a move all the time, at every grade level. Do what seems right for the specific kids involved.
