We did have him in a private preschool where he acted up because the work was too easy. He was the youngest in class and finished way before the other kids and then, went bonkers out of sheer boredom. They refused to accelerate him.
So, we went to a private montessori for the next two years. You score a 0 (not presented to student), 1 (presented) 2 (in progress) or 3 (mastery). His first report card was all 2's and 3's even though he joined the class several months in. By the first couple months of the next year, he had mastered every thing. The school acknowledged his intelligence but refused to accelerate him. He was bored, told them he was bored but they told him they needed to focus on slower kids and he should just be patient. He turned into a raving maniac, wandered around, talked to other kids who were hard at work, drew a lot of pictures. We didn't quite "get it" and didn't realize that we needed to advocate or move him into a different school.
Now he's in public K so you can draw your own conclusions about what that's like!
