In an unexpected action last summer, the Los Angeles Times published the ratings of teacher effectiveness for 6,000 teachers by name. This is a potential game-changer.
The publication created a firestorm. The unions were apoplectic. A vocal set of commentators attacked this action from a variety of viewpoints. Nonetheless, it shows signs of spreading – to New York City and elsewhere. Since my research started this development, I believe it is useful to share my perspectives on how we should judge this development and whether we should stop its spread.
