New York: Officials Considering Using SAT Scores and AP Exam Results to Evaluate Teachers, by Diane Ravitch

Destroying the profession: "Here is one of the dumbest ideas of the 24-hour news cycle. In education these days, there are many dumb ideas advanced on a daily basis, so it is hard to pick just one as the dumbest. But this is it.   Officials at the New York State Education Department  are considering using SAT scores and the results of AP tests to evaluate high school teachers.  Since these scores, like all standardized test scores, are highly correlated with family income, those who teach in affluent districts will get the highest ratings, and those who teach students who live in poverty will get low ratings. But also, the idea violates the basic rule of testing: Tests should be used only for the purpose for which they were designed. Neither the SAT nor the AP exams were designed to evaluate teachers.
