Michelle Rhee to announce resignation as D.C. schools chancellor on Wednesday

D.C. Schools Chancellor Michelle A. Rhee will announce Wednesday that she is resigning at the end of this month, bringing an abrupt end to a tenure that drew national acclaim but that also became a central issue in an election that sent her patron, Mayor Adrian M. Fenty, to defeat.
Rhee survived three contentious years that made her a superstar of the education reform movement and one of the longest-serving school leaders in the city in two decades. Student test scores rose, and the teachers union accepted a contract that gave the chancellor sweeping powers to fire the lowest-performing among them.
But Rhee will leave with considerable unfinished business in her quest to improve teaching, close the worst schools and infuse a culture of excellence in a system that has been one of the nation’s least effective at educating students.
