The Highs, Lows Of D.C. Schools Chief Michelle Rhee
Washington, D.C., Schools Chancellor Michelle Rhee announced her resignation on Thursday. Rhee turned the city's failing public school system into a national laboratory for education reform. She closed schools, fired teachers and instituted a pay-for-performance system based on student test scores. But her tenure was also marked by battles with the teachers union and growing distrust along racial and political lines.
