Well, he will presumably have his sister's gifted magnet available to him in 2nd grade, which is great. He isn't as driven as his sister, either, despite the fact that I suspect he will start K reading even better than she did (she wasn't reading till almost 5, so he's going to have an additional year to build skills, which are rocketing along; yesterday he was reading me phrases like "North American Owls" and the "The female anglerfish has a glowing lure to attract fish"). So if we skip, we're looking at a skipped kid in a GT magnet, most likely, which I would want to consider carefully, though his sister could probably handle a skip right now except perhaps for the writing and research element, which is big there. The good news is that the school where the magnet is is open to skipping--I know of at least one recent case where a K kid was skipped to 1 on the school's initiative because of the skills he came in with.
