Well, I would definitely get a feel from your DD's regular teacher and her GT teacher as far as their perceptions of her ability and achievement relative to her peers. As far as acceleration, it can proceed smoothly if her teachers agreed that she is an outlier. The fact that her MAP scores have dropped considerably from Fall 1st grade to Fall 3rd grade can impede your advocacy especially if she has many classmates who score higher. You may want to enrich before seeking acceleration in hopes of bringing up her scores. Talent Search (JHU CTY, NUMATS, Duke TIP, Belin-Blank, etc.) may be a place to start.
