Local school boards must take action now. They still have the legal authority in every single state even if they are told they don’t, or think they don’t.
They must, upon petition by parents asap, vote (1) to allow parents to opt-out their children from any Common Core-based test (pilot, field, or regular); (2) to forbid any further implementation of curriculum based on and addressing CC standards; (3) to eliminate use of CC standards in their school district; (4) to develop/adopt any other set of standards in ELA, math, or science they want; and (5) to require their K-12 curriculum to address these other standards once they are developed/adopted.
Every local school board has the legal authority to require these actions. Only the state legislature can pass a bill that eliminates local control/authority. No state legislature will.
I will give 1-2 free days of professional development to develop first-rate ELA standards with the English/reading teachers in any school district in the country that votes the above. All it has to do is pay my travel expenses.
