Teacher accountability and the Chicago teachers strike | Economic Policy Institute

Richard Rothstein, as he often does, makes important point after important point in this article. I was fortunate to be part of a large discussion in the School of Education earlier this week, and Lorrie Shepard said some smart things (she tends to do that a lot) about "weighing" versus "weighting." We know traditional forms of teacher evaluation haven't always identified underperforming teachers, and we have to own up to the fact that's a big reason we're seeing policy battles like we see in Chicago. But instead of "weighting" information from student test scores -- meaning make them some percentage of a formula that spits out teacher quality scores -- Shepard says we shouldn't give up "weighing," meaning to accept a variety of evidence that shapes an overall picture of teacher quality that can be judged by trained and qualified administrators.
