Based on a three-year study of a dozen secondary schools in a large urban area, this book explores the clear and interesting differences between the schools that promote success and the schools that promote failure. As Rutter shows, these provide important clues to the kind of educational reform that might allow schools to more uniformly provide positive and protective influences on students who must grow up in a disordered and difficult world. Rutter is a psychiatrist who is also a sociologist, and we think that has made this book special. We believe that the book has many powerful lessons to offer educationists. Through precision measurement of virtually every aspect of the school environment, the book brings us to an understanding of how the smallest things in a school can have a large impact. It is highly recommended reading for educators.
