The U.S. Department of Education is doing something to the nation's schools that has never been done before.
Through the leverage of its Race to the Top program, it has persuaded, pushed, and prodded at least 36 states to evaluate teachers by the test scores of their students.
There is no evidence that this will improve education or teaching. There is reason to believe it will incentivize narrowing the curriculum, cheating, and teaching to the test.
