After last December's school shooting in Newtown, Conn., the Division of Homeland Security & Emergency Management conducted a survey and determined that N.H.’s school buildings are at widely varied levels of security. In response, they developed the following recommendations based on three core standards: Surveillance, Access Control, & Emergency Alerting. Each school will have to take into account their budgetary constraints & environmental factors when considering how to implement the guidelines.
Sometimes, a picture (or a chart, graph, video, or map) tells a better story.
