I will definitely keep this in mind in case skipping first becomes a possibility. I should clarify, though, that the question isn't whether to skip K, it's whether to start K a year early (so basically whether to skip a year of pre-K). DH and I both work so if we don't start DS in kindergarten this fall, he will be sitting through another year of pre-K at his day care. We've met with his day care multiple times and they just don't have the bandwidth or training to really do any differentiation, so he'd be stuck counting to 50 and doing "letter of the week" for another year.

Early K sounds like a good option: still play-based, with lots of time with friends, some writing, and reading/math that can be differentiated to any level (according to the district AIG coordinator, at least).
