Thank you all for your responses - this is very helpful! DD's school re-tests in 3rd grade, so I'm anxious to see what we learn then. This information gives me the "ballpark" I was hoping for. There is a gifted summer camp at W&M that we're considering and now I think I'll go ahead and apply.
I am glad to have found this board. We deal with many of the issues I've read about here - anxiety, over-sensitivities, boredom with schoolwork, etc. I know this board will be a valuable resource!
Thanks again for the feedback!
