Sadly, education will never improve until it is nationalized. As long as states can influence the coverage of something like evolution they are unfit for making choices for those children.
Not all states push creationism on the curriculum, and some states, like California, are both economically productive enough and populous enough to be their own nations. Despite that, California has some of the worst average educational attainment in the nation. How, exactly, would nationalizing improve the situation?
This is happening to an extent with the wide adoption of the Common Core. Unfortunately, at least with regard to math, this curriculum is not better than all of the state versions it's replacing. I'd rather see something like tying funding to evidence that a particular strategy might work.
Except that education has gotten worse and more expensive as it's be centralized. I in fact would prefer a much more distributed form of education where school vouchers allow schools to compete for students and parents can choose a school that educates in the way they'd prefer.
