I forgot to ask:  How is the social level for your DD?  Is she advanced in that area as well or is she with a good group of social-peers?  Also, how old is she compared to the other children in her class?  If the social fit is also poor, could you look into moving her into a K classroom?  K offers the same opportunities as pre-K for learning school, with all its emphasis on sitting still and following rules and lining up and listening to a teacher, but with possible slightly more appropriate academic challenges.  Just something to think about.
