Tragic events lead to new prevention and response strategies. We recognize that there are dangers in our communities and in our schools. These realities call for an enhanced focus on safety. The decades-old school fire drill has evolved to active shooter/threat drills as threats have escalated and materialized, often with tragic outcomes. Our nation is seeking new and innovative ways to keep children and adults safe in school settings. Far from simply developing techniques to respond efficiently to an active incident, public safety officials are also exploring technologies to gauge and prevent potential crises. And they are sharing their ideas and results. Across the country, entire communities are rallying and dedicating themselves to being proactive in preventing school violence. There is much talk about how existing programs can be reinvigorated, what new technologies can be created and how training tools can be distributed to school resource officers (SROs), administrators and local law enforcement agencies. Modern threats are being addressed with modern technology, strategy and resolve. The U.S. Department of Justice's National Institute of Justice (NIJ) is a leader in identifying and sharing new training and technology with law enforcement and other first responders. Since Congress passed the Safe Schools Initiative 15 years ago, NIJ has worked collaboratively with other federal agencies on behalf of our nation's law enforcement to answer the call to develop tools and strategies to boost security in our schools. Front-line professionals are working more closely with teachers and administrators, students, parents and community leaders to create alliances that will transform our nation's schools. NIJ, through the National Law Enforcement and Corrections Technology Center (NLECTC), is helping communities gather and share their success stories in this publication and at SchoolSafetyInfo.org. In this guide, you will read about new uses for familiar, standard-bearing technologies such as: 1) Advanced Law Enforcement Rapid Response Training (ALERRT). 2) NIJ's School Critical Incident Planning-Generator (SCIP-G) tool. 3) NLECTC System video "It Can Happen Here." 4) Free online training from International Association of Chiefs of Police. 5) School Safety Audits. In addition, you will read about new products and apps such as: 1) Anne Arundel County (Md.) Police Department's Speak Out app. 2) Tucson's Mass Casualty Trauma Kits. 3) SmartPhone app for students to communicate with police. 4) See-Hear-Report text a tip program. 5) Real Time Location Systems (RTLS). This guide also reports on unique collaborative community efforts that are succeeding in cities and rural areas alike. It's a new day in the effort to keep schools safe. Law enforcement and public safety officials now team with and count on students, school officials, parents and all concerned citizens to share the responsibility to keep schools safe.
