So then how do you fire a teacher for being incompetent?

My question would be, "How do you correlate test scores with teaching?" Most such schemes (including bonus pay for scores, etc.) assume that all kids are identical. A teacher who gets 75% of his lower-level (i.e. reading 3-4 years below grade-level) kids to pass a standardized test may very well be a miracle worker. An honors teacher with a 75% pass rate is a worthless lump ... honors kids ought to have a 100% rate with little effort on a minimum standards test). So how do you factor in these variables without simply firing every teacher who is unlucky enough to teach low-levels? And who decides which teachers' test scores are evidence of their teaching and not other variables (who watches the watchmen...)?

So you did answer my question because teachers just don't get fired for incompetence.
