Jay Mathews has written a new book about KIPP titled "Work Hard. Be Nice." The story is about Mike Feinberg and David Levin who started the KIPP schools. Both were teachers in a middle school in Houston who started out with a very challenging student population with little demonstrated academic achievement. After turning around their school they began training other teachers and eventually new school leaders. There are presently 66 KIPP schools operating in the United States.
