Undergraduate capstone courses in sociology are designed to integrate students' knowledge in the discipline and to culminate the classroom experience with field application. Are capstones achieving these goals in a durable way? Although the short-term outcomes of capstone courses have been researched, fewer studies have documented the long-term outcomes of capstone courses. We conducted a survey of sociology capstone alumni to understand the long-term outcomes of the sociology capstone by asking sociology alumni about their capstone experience. Our research revealed that all capstones produced long-term outcomes as measured in the alumni survey. Second, alumni of the community-based research capstone experienced a more profound and longer reaching effect than those who participated in the internship or traditional capstone seminar format. Alumni reported the development of professional skills, application of sociological concepts and research skills, and a sense of being part of a community.
