So it begins. I think in a lot of districts early entrance is an uphill battle. Enrolling our DS in K for a few months gave the school a chance to know him and see that he is not a "flash card" kid, as you (or possibly your principal?) put it. I think that helped them be more open to the trial of first grade. Still, I think they expected it to be a disaster and thought they would prove to us that skipping was not an option. Somehow, you have to get them to allow your DS to show his stuff. Just showing them numbers doesn't really seem to convince school administrators.
