Well, when the data looks like this... http://mathbabe.org/2012/03/06/the-value-added-teacher-model-sucks/ http://mathbabe.org/2012/03/06/the-value-added-teacher-model... That could be embarrassing. "Objective" teacher performance measures all seem to be as bad as, if not worse than measuring programmer performance with SLOC. Oddly enough it looks like the proposals he was trying to ram through in New Jersey look like a attempt at teacher union busting. Why Zuckerberg would involve himself in that is a bit of a mystery. While he seems to be the public face, it could be that a lot of the money doesn't come from him.
