In a speech to the Institute of Education Sciences today, Arne Duncan criticized states that have banned the use of student achievement data to evaluate individual teachers, declaring that not judging teachers on student achivement "is like suggesting we judge sports teams without looking at the box score." Sounds reasonable, although that particular analogy makes me wonder if he's read this piece about Shane Battier, the "no stats all star."

Here's the press release, Ed Week's Michele McNeil, and Charlie Barone.

Update: Text from the speech is in this discussion.
