This study involved implementing and evaluating a project built on multi-agency collaboration and a randomized controlled trial of multi-tiered, trauma-informed, evidence-based practices in one high school, 2 middle schools, and 8 elementary schools in Bozeman, Montana. The School and Family Engagement: Trauma-Informed (SAFE-TI) project comprised a package of 6 varied interventions with the potential to impact discipline, truancy, recidivism, aggression, risk-taking, and suicidal ideation or attempts, and was tested relative to treatment as usual. Quantitative data collected included student absences and safety-related behavior. Analysis was performed at the school building level.
