Hi Beth,
We offer a study skills course that is mandated for students entering the university deemed underprepared. One assignment for the course is to pick from 4 options, tutoring, writing center, math center, or career and professional development center and have a meeting/appointment. We do the same assignment for our academic probation course. This is as close as we have gotten to mandating support services. Sadly, even with points attached, a fair number just don't complete this assignment.
I am interested in what others are doing so thanks for bringing this to the list.
Take care,
Lynda
