Another reason you don't want government running education

In Minnesota, the legislature is debating whether reductions in force in school districts ought to involve ratings of teacher performance.  Now how this criterion ought to be used, or what limits ought to be imposed, but whether teachers should face termination for poor performance.  The teachers' union representative went on to note that evaluating teacher performance would be the hardest challenge they'd ever faced.

Call my cynical or judgmental, but I would have hoped that a good measure of teacher performance would be "are the kids learning what is to be learned?"  And with logic like that--to stand on a soapbox I use often--I guess we understand better a lot of things in our country, don't we?
