I would request a skip if your school has no GT program. Get hold of a copy of the Iowa Acceleration Scale and fill it out. It is a very objective survey, and schools are usually receptive to it once they see that it covers all kinds of things, not just test scores.
Find out also who the 2nd and 3rd grade teachers are -- if there's a 2nd grade teacher who really and truly can differentiate, compared with 3rd grade teachers who cannot -- definitely something to consider. Also see if you can find out about the class your DD would skip into. Do those kids have similar scores to hers? What are the kids like?
