Alumni service resources available to a large Chicago-area community college were studied. A six-year followup study was conducted at Harper College with a population of students who completed 48 or more semester hours during the 1974-1975 academic year. A sample of 543 alumni were asked whether they would be willing to provide a variety of services to the college. Names of alumni who were interested in helping the college were provided to school staff. After a six-month period, staff members were interviewed as to the coordination effort required to reach the alumni and use their services. They also indicated if these services were beneficial. The cost of the survey and the coordination effort was estimated, and a dollar figure was placed on the services received. In addition, interviews were conducted with staff who had been using alumni services through informal channels over the years. It was concluded that followup studies to identify alumni volunteers are relatively inexpensive, but the substantial benefits that can be derived from alumni services are substantial. This is illustrated by a description of how the legal technology program at the college uses alumni. The key to any successful alumni volunteer program seems to be effective coordination. (SW)
