This is a revision of a core text for the juvenile delinquency course, taught either out of sociology or criminal justice. One of the challenges in teaching this course is that, while students are inherently interested in the subject matter, they can get overwhelmed by the theory, which is the heart of the course. Instead of attempting to cover every variation on every theory ever developed, Robert Agnew and Timothy Brezina summarize the main theoretical points that students need to understand, and presents them clearly and accessibly. The text is organized around three major questions: 1) What is the nature and extent of delinquency? 2) What are the causes of delinquency? 3) What strategies should we employ to control deniquency? This question-centered approach is the core of the book.
