Obama’s former budget director Peter Orszag recently wrote an article claiming that teachers should be judged by the test scores of their students. He read about the Raj Chetty study and the Gates MET study, and that was good enough for him.

From what he writes, it is clear that he knows nothing of the research critiquing those two studies. Hundreds of millions of scarce dollars are being wasted to make VAM work. It is not working anywhere. The tests are not designed to measure teacher quality.

VAM is junk science.

Not to worry, Orszag is a banker so he knows how to evaluate teachers.

Here, Mercedes Schneider examines Peter Orszag’s assertions.
