School safety challenges continue to evolve as it seems every day there's a new story about a security lapse, lock-down, or violent act taking place. In this thoroughly revised edition, Paul Timm, a nationally acclaimed school security expert, explains how to make educational institutions a safer place to learn. Throughout the book, Timm emphasizes a proactive rather than reactive approach to school security. Readers are introduced to basic loss prevention and safety concepts, including how to communicate safety information to students and staff, how to raise security awareness, and how to prepare for emergencies. The book discusses how to positively influence student behavior, lead staff training programs, and write sound security policies. School Security isn't just for security professionals: it helps people without formal security training-educators and school administrators-effectively address school risk.
