Designed to provide basic guidelines and examples that can be used by community colleges for organizing and conducting community impact studies, this booklet describes the experiences of Kalamazoo Valley Community College (KVCC), Eastfield College (EC), and Valencia Community College (VCC) in conducting their impact studies. Introductory material offers a rationale for assessing a college's economic (related to institutional expenditures, changes in income, standard of living, or job security), educational (related to the development of new skills and competencies), social (related to changes in family, recreational, and cultural activities), or technological (related to syntheses or reformulations of knowledge) impacts on the individuals, groups, and organizations in its community. In addition, this section describes the case study institutions, and presents a brief review of related research. The remainder of the booklet reports on the three studies, providing background information, describing methodology and survey populations, summarizing results, and explaining how the findings were used in improving community relations and promoting the colleges.A short bibliography is appended.
