I actually like your district's statement on Common Core policy - I wish that our P.S. recognized this, as well. The Common Core is indeed a floor, and not a ceiling.
If G&T is so supported in your state, P.S. may be worth looking at. It is worth listening to what they have to say.
I think that going into the school and expecting them to overhaul the entire system in a short period of time is unrealistic (I'm not suggesting that this is what you are trying to do, btw). Change in public schools takes time - sometimes too much time to actually improve it for your own children. If, however, they have basically good programming that they are continually working to improve - it is worth considering.
