A detailed examination of the ways in which teachers and educational psychologists are responding to the challenge of asserting discipline in schools, this book presents the results of a national survey of educational psychologists detailing 68 interventions with difficult pupils. It summarizes the aspects most associated with successful outcomes, and then examines the results of in-depth interviews with 24 teachers who have worked successfully with educational psychologists in overcoming the problems presented to them by a difficult pupil. The many cases the teacher describes the pupil as the most difficult they have ever encountered, and yet they have achieved considerable and even dramatically unexpected improvements.
