Accountability up and down the line. Which means the government employees will fight it to the bitter end.
Accountability is essential in the provision of any social service from any institution to any segment of society.
It would probably be beneficial to get Government out of education, altogether, if there was some non political body that could manage a safety-net for those children whose parents are not able, otherwise, to secure their education.
The way that the "Welfare" ("Safety-Net") was handled in Jefferson's time, is a model for what actual works in social programs--although, admittedly, education involves a quite different set of immediate considerations. (See Jefferson On Welfare.)
On my wish list of constitutional amendments is the abolishment of all public employee unions.
