Do away with the Department of Education. Return all education monies to the states. Let each local community run their schools.
Set up a plan where-by local schools would hire in a private administrative team to run the school. Let them do the hiring and firing, with the stipulation that tenure not be incorporated into the plan. Teachers would be placed on the payroll only after they signed a no-cause termination agreement.
Teachers would be non-union. If they did unionize, the local town could simply cancel the contract with the private school administration.
When a new administration entity came along, there would be no teachers hired from the former staff.
I know this is a tough love approach, but the gravy train was bound to end sometime. End it today!
Your plan sounds like a good first starter. I doubt that everything you propose would even get close to flying....but, getting rid of the Dept. of Education, and returning control to local schools, etc. I doubt that restricting the formation of unions would hold muster at the court level, though I agree with you...they're a huge part of the problem (mostly the NEA)...so, aside from getting completely rid of them, there needs to be control of what they do (mostly what they do know is act as a whacko leftwing anti-American, anti-families, political lobby with teacher dues). I don't think it's necessary to get rid of all teachers; there are a great many good ones out there; and many of them have been either intimidated by the liberal Superintendents/Principals to teach that which they'd prefer (lots better teaching ideas/methods than what the NEA wants done).
ooops "mostly what they do know" should be "mostly what they do now"
