After about a year-and-a-half on the job, Jean-Claude Brizard is out as CEO of the Chicago Public School System. | Brizard reportedly said he was becoming a distraction from the mission to help Chicago's children, reports the Chicago Tribune. Brizard made a similar statement before leaving the Rochester school system, where he was superintendent from late 2007 to April 2011. | Brizard left Rochester for the Chicago post under a cloud of controversy. He had tried to push an agenda similar to that espoused by education reformers Joel Klein, former head of the New York City school system, and Michelle Rhee, former head of the Washington, DC schools. | Though he initially had the support of most Rochester school board members, Brizard and Rochester Teachers Association President Adam Urbanski became bitter adversaries. In an overwhelming vote of no confidence against Brizard, Rochester teachers expressed their dissatisfaction with his management and communication style. | It was widely expected that Brizard would succeed under Chicago's mayoral control form of school management, but the Chicago teachers strike unleashed a weeklong drama that gripped the nation. | Brizard is being replaced by Barbara Byrd-Bennett, the Chicago district's chief education officer, according to the Tribune.
