G.F. Brandenburg writes a terrific blog, where he uses data to refute reformer exaggerations. He was one of the first, for example, to break the story about Michelle Rhee’s inflated claims of success as a young teacher in Baltimore.

Here he displays the data comparing DC public schools to charter schools. It is a healthy antidote to the fantasy so often spun by Arne Duncan, Michelle Rhee, Joel Klein, and the other luminaries of the reform movement.
