I agree with Dottie. DD's maturity became a convenient reason why she would act a certain way. She was accelerated by 1 year at that point and she was simply not challenged and spent most of her day daydreaming and talking to other students. Teacher bias is certainly something to be considered, since some don't believe in acceleration. When DD was subject accelerated further, the maturity concern wasn't there, because she was busy paying attention to challenging material.
Now at 10, she prefers to spend time with out 14-16 year old babysitters or oldest classmates (12+) and in my observation she is not physically as developed, but socially/intellectually it seems a good match.
In my observation, DDs maturity has only grown with time, not the other way around. Her interests in science and ecology is that of a HS student (according to our science teacher this year) and her motivation to learn has only improved with appropriate challenge.
HTH!
