The Montana Behavioral Initiative (MBI) was developed in 1995 in response to increased incidents of student behavior problems. The intent of MBI is to improve educational environments to meet the needs of all students, including those with behavioral challenges. Each participating school conducts needs assessments and develops site-specific goals and strategies. Support is provided by an annual summer institute for staff development, MBI facilitators and consultants, an MBI council, and a state coordinator. A program evaluation conducted structured interviews and focus groups at five MBI schools at three levels of program adoption: established, emerging, and new. Recommendations include clearly distinguishing the MBI philosophy and process; tailoring future summer-institute content to areas of need identified from experienced sites; developing assessment practices that identify easily-tracked behavioral and academic measures; identifying computerized data entry and analysis programs that support MBI indicators more directly; providing mentoring support for new MBI sites; developing incentives to encourage stronger school-community linkages in MBI sites; creating a central listing of research-based practices and programs; clearly delineating criteria for recognizing approved MBI sites and facilitators; integrating MBI youth events into professional development venues; developing professional development sessions specifically for high school athletic coaches; and communicating MBI philosophy and process to a broader organizational and policy environment.
