The skip is a good start, then follow closely and go from there. The problem here it that it appears they don't identify the kids til third grade. It's hard for them to accomodate kids within district policy, if the gifted policy isn't addressed til then.
I'm finding that the sticking point in our district is they can't seem to do anyting "special" or different for just one child. They have to have a "group" in order to justify a different curriculum and if they haven't identified any other kids or the parents haven't been assertive like you have, their hands are somewhat tied. I've found it's good to figure out what the district policies are because sometimes there is little the teacher or principal can do, per district policy. Once you know the policies, it's then a little easier to navigate them and figure out how to get a realistic education plan put into place.
