Summary Schools are under scrutiny and pressure to provide safe spaces in which children can develop and learn. While this should include all aspects of a child's well-being, national coverage of school shootings has tipped the scales toward preventing mass violence in schools, often sacrificing the indoor environmental quality of the school space. Children face a real threat of bullying, asthma, absenteeism, obesity, and attention deficit hyperactivity disorder when they go to school every day, rather than the infinitesimal possibility of being involved in a mass school violence event, such as a school shooting. school. This project would reference existing strategies, case studies and ideas from a variety of sources and practitioners and synergize them to create a reference tool that addresses safety, well-being and high indoor environmental qualities together rather than as objectives isolated. This guideline will serve as a decision-making tool for administrators, architects, teachers, police, and policy makers to make informed decisions about student health and safety that consider everyday exposures as well as rare cases of mass violence. The initial structure of this guideline was created as part of a master's synthesis project and will be redeveloped for broader integration and use. Goals and Meaning School administrators and teachers today must balance student priorities in their classrooms. Schools are concerned with student achievement to meet national guidelines and with student well-being to enable appropriate development during the childhood years. Added to this balance is concern about mass violence in schools. Because the recent school…middle of the road…pick and choose what may or may not apply to their structures and operations. This guideline also offers the ability to look ahead and look at districts' operational guidelines to discover where certain strategies can be implemented as part of their standards. The priority of this project is to help decision makers in school systems make more informed health and safety decisions by encouraging them to consider the whole child on both an everyday and worst-case scenario scale. The large body of knowledge that will be available for use by school systems across the nation mitigates possible obstacles faced by the research team. By ensuring that students have a healthy, high-achieving classroom every day, their school experience will be more positive in terms of health, behavior and well-being without creating a sense of fear about actively preventing violence.
