Mr W was evaluated at his Montessori School and we found that they just did the "three year" old stuff as the ceiling. When we looked at the evaluation form, which went all the way through K, he had almost all of it. Their response was that they just stop at three because he was just turned three.
I wish I had a nickle for every time I've heard that story. It seems to be 'unAmerican' or something like it to want the simple courtesy of being seen for who you are at a particular moment in a school setting.
