The Student Success Program (SSP) at Mohawk College of Applied Arts and Technology, in Ontario (Canada), combines institutional research, intervention strategies, and evaluation to form an effective model of student retention. The institutional research component is managed by the Retention Information System (RIS), which collects demographic, withdrawal, performance, and tracking data from the mainframe student information system. Intervention strategies focus on academic and social orientation of new and existing students, assessment of students early in the first semester, peer tutoring and support groups, learning strategy seminars, and the creation of offices of Special Needs and Student Success. Intervention strategies are evaluated by comparing retention rates in programs by semester and comparing retention outcomes for programs with strategies and those without. The SSP is unique in that it has developed from grass-roots efforts in the college and was not mandated by senior administration. It arose from a pilot project to analyze outcomes in high attrition areas in the fall of 1987, and the subsequent formation of a consultative team for student success. Currently, it operates out of the Office of Student Success, which maintains a full-time coordinator, part-time statistician, and part-time research assistant. Over the past 3 years, the SSP has raised awareness of student success issues at the college, continued to develop the RIS, and significantly reduced attrition in at least six program areas. (BCY)
