In 2002, New York City's newly elected mayor Michael Bloomberg made a historic announcement: His administration had won control of the city's school system in a first step toward reversing its precipitous decline. In a controversial move, he appointed Joel Klein, an accomplished lawyer from outside the education establishment, to lead this ambitious campaign. Lessons of Hope is Klein's inside account of his eight-year mission of improvement: demanding accountability, eliminating political favoritism, and battling a powerful teachers union that seemed determined to protect a status quo that didn't work for kids. Klein's initiatives resulted in more school choice, higher graduation rates, and improved test scores. The New York City model is now seen as a national standard for meaningful school reform. But the journey was not easy. Klein faced resistance and conflict at every turn.
