Insiders credit Brill's devastating 2009 New Yorker article about New York City's so-called rubber rooms with the district's decision to stop making teachers accused of misconduct sit in empty rooms, twiddling their thumbs for eight hours a day, during the months and often years it takes for their cases to work their way through a byzantine system of hearings. Now the veteran investigative journalist is working on a book about how education reformers have moved from the margins to the mainstream over the past two decades. Expect the book, which is scheduled to be released late this year, to change the way Americans think about school reform and to showcase other rubber-room-esque practices that make no sense and waste a lot of money.
