Solutions through School, Justice, and Behavioral Health Collaboration School responses to disruptive student behavior often do not address underlying behavioral health issues that are driving these incidents. Instead, children with behavioral health conditions are often marginalized through the use of exclusionary discipline policies that disrupt their education. These practices disadvantage youth and leave comprehensive school safety efforts without effective strategies to meet student and faculty needs for physical and psychological safety and well-being. This comprehensive research study examines the impacts of two intervention strategies, the School-Justice-Mental Health Collaborative and the Adolescent Mental Health Training for School Resource Officers, on promoting school climate and school safety. Working in partnership with sixteen high schools in Louisiana and Michigan and program and research partners at the Child Health and Development Institute and Louisiana State University, this study will provide an evidence base for how training and collaboration between schools, law enforcement, and community-based providers to identify and treat mental health issues among students can positively impact school climate and school safety.
