Against Merit Pay for Teachers
That would be my position.
A government-run system of teacher compensation, based on test scores, would in some ways be the worst of all worlds. It would create incentives for teachers to “game” the system. It would give too much weight to a noisy indicator of performance. As a result, it would do little or nothing to improve accountability or to reward better teachers.
I think that the only solution is to get the government out of the business of providing education. A few days ago, I finally got around to watching the documentary Waiting for Superman. That film could be interpreted as making an even more passionate statement in favor of getting government out and letting private firms compete.
