A former teacher, principal, and longtime advocate of early childhood education will be the next leader of the nation's largest public school system, New York City's incoming mayor announced Monday.

Carmen Farina, 70, a former deputy chancellor, will bring a wealth of insider's experience and fresh ideas to the job, Bill de Blasio said. "She knows it because she's lived it," he said. "This is literally one of the most important decisions I'll ever make as mayor."

Said Farina: "It's such a privilege to be able to come back to a system that has so much work yet to be done, but to be doing it from a stance of a progressive agenda." - AP
