Why do some colleges and universities—even those with limited resources—achieve high graduation rates while others do not? Over the past three years, several Vassar administrators, a faculty member, and a student have been engaged in research designed to help answer this question. They will present their findings and continue this discussion at a symposium on April 29 at The Vassar Institute for the Liberal Arts. Representatives from a dozen colleges, foundation leaders, and policy makers are expected to attend.
