Whay will happen, when States run their own schools?

The terms "National Education Association" and "teaching" are synonymous with one another. The National Education Association is the most popular teacher's union in the United States, but they are also the most scrutinized. Their primary goal is to protect teacher rights and to ensure that their members are getting treated fairly. The NEA has arguably done more for teachers and public education than any other advocacy group in the United States. Get an overview of the National Education Association, including a brief history and what they stand for.

So the NEA collects around 500 million per year, in order to protect teachers rights?
What does that mean?

I think you'll see red states performing leaps and bounds over blue states. A good comparison will be to compare the financial condition of red versus blue states. You can expect the schools to perform in about the same fashion.

States already do run their own schools. There is no national curriculum directing what must be taught or how. There are national standards but it is up to each state to either adopt, modify, or reject those standards. The department of Ed basically coordinates the allocation of federal funds for school nutrition, special education, and other programs that benefit students who need special considerations.

States do run the schools.
They will lose Federal funding.

Cant wait for those red states to 'improve' their schools on their own.

Now that the Department of Education is being dismantled you will see what happens!

The DOE contributes nothing to the education system. Just a bunch of overpaid bureaucrats
