Using the violent events that took place at Columbine High School in 1999 as an example, this book serves to inform teachers, administrators, school resource officers, and concerned parents about school violence. It can be used to help develop a response and prevention plan to handle threats and violence in schools. This book is a guidance manual designed to empower school officials in their goal of preventing schoolplace violence. It offers step-by-step advice to assist in the early identification, intervention, prevention, and containment procedures that can reduce the risk of school violence. It outlines the dynamics and characteristics of violence, provides information on how to recognize it, and offers prevention and intervention strategies. Unlike many other forms of violence, schoolplace violence is very predictable. It follows a specific course of action and this, in turn, offers many opportunities for intervention and determent. The goal of this book is to emphasize the first steps toward prevention: education and training. A bibliography lists resources on the topic of violence prevention, intervention, and aftermath. (MKA)
