My experience was the same, my daughter started out K reading at 2nd grade level but requests to skip K were shot down from the start because of immaturity. She wasted the whole K year sitting around bored at school as her classmates learned the alphabet etc, and the end result was that she became very lazy when it came to school work. She has stayed emotionally and socially immature because she never gets to be around people she feels comfortable with, her same age peers think she's a know it all, and don't like to talk about the same things she does. If I could go back to that first meeting I would have done so much more to try and get them to move her, it would have been so much better for her.
