Those red states are gonna be fukked. If you live in a state who's Department of Education is run by competent people, your kids should be fine.
There is some merit to removing federal bureaucracy to some departments. For example, through the No Child Left Behind Act, it mandated states to set testing standards which has been a complete disaster. Most of these schools teaching kids on how to pass these tests, instead of actually teaching to learn. And through these tests, funding was allocated based on performance. It has become a cash grab for a lot of districts with teachers even cheating and changing answers to student's tests or some other tomfoolery.
I don't agree with completely removing DoE, but it needs to be revamped.
