This executive summary presents evaluation findings and conclusions from a 4-year study of a demonstration project focusing on a school-based and school-linked interprofessional case management approach to dropout prevention. The project, funded by the U.S. Department of Education, was administered by the Center for the Study and Teaching of At-Risk Students (C-STARS) at the University of Washington and Washington State University. During the project, a generic model for interprofessional case management was introduced in 5 school districts (28 schools). The model consisted of a set of guidelines for site-tailored delivery of case management services, and it included an evaluation component to assess outcomes. Each district targeted case management services in consideration of its unique demographic and service need priorities. An inner-city district, a suburban district, and districts with high numbers of American Indians, Hispanic American students, and low-income rural students participated. An analysis of attendance, academic grade, and misconduct data revealed that students who met the C-STARS criteria generally improved in these areas while receiving case management services. Over the 4 years there were measurable improvements in all three areas, and there was an increase in progress toward or attainment of service goals each of the last 3 years of the project. Factors that contributed to effective case management were identified, and it was also found that the involvement of teachers and family members in the case management process was essential. Overall, findings demonstrate that school-based interprofessional case management as demonstrated at these sites is a viable means of addressing problems of at-risk students and their families. (SLD)
