A behind-the-scenes campaign called Common Core State Standards was driven by policymakers in Washington D.C. onto every state except Alaska, Minnesota, Nebraska, Texas, and Virginia.
This was done with insufficient public dialogue or feedback from experienced educators and parents. No research, no pilot or experimental programs, no evidence at all that a floor-length list created by unnamed people attempting to push their indoctrination onto America's children was implemented by the federal government.
Even if you ignore the fact that specific Common Core State Standards will open up enough cans of worms to keep subject-matter specialists arguing among themselves forever, consider how far the program itself falls short of the American education system that once existed in this country.
The Washington Policy Center has conducted in depth research and found common core fails our nation's children.

The ultimate goal of Common Core is to have every school district follow the same national standards. This is a failed educational approach that will undermine educational quality and choice. States and local communities better know how to design standards based on their students and parents’ needs than Washington bureaucrats who want your child to be a dumbed down immoral person who votes Democrat.
