I have an even "better" story from my own childhood. My brother was already reading in kindergarten, and none of his classmates were. The kindergarten teacher wanted to have him do reading in the 1st grade classroom, and my mother said no, because she didn't want the other kids picking on him. (I think this was not a great decision on her part, or at least not the one I would have made, but I'm sure she was doing the best she could.) So their solution was to put him in first grade for reading anyway, and swear both him and me (in first grade) to secrecy. She didn't find out about it for years.
