The Safe Schools/Healthy Students Initiative was designed to encourage collaboration among school districts and local community service providers in the provision of behavioral health prevention and early intervention efforts. These efforts would address the physical safety of students as well as provide mental health, violence prevention, and social skills services. One local SS/HS Initiative brought together community and school collaborators in an ambitious agenda that included 14 distinct programs that addressed the needs of over 110,000 students in a large school district. The purpose of the current paper is to report the results of the evaluation of two of the programs designed to reduce violent and disruptive behavior in schools. The programs include a school-based anger management program and a community-based, alternative-to-suspension program. Working in cooperation with program staff and the school district, quasi-experimental designs were used to measure change over time for students. The two studies demonstrate the application of multiple methodologies in evaluating the effectiveness of prevention and early intervention efforts with the aim of providing data to support program improvement and sustainability.
