Documenting the impact of 1978-79 Community Resource Development (CRD) projects, this national study presents data in response to a congressional mandate calling for assessment of the consequences and effectiveness of Community Resource Development projects. The report presents findings derived from questionnaires sent to 47 state CRD leaders, 120 randomly chosen extension workers who had completed or nearly completed a CRD project in the past 18 months, 14 CRD workers associated with 1,890 institutions, 53 extension service workers who served as local case study contacts, and over 1,000 knowledgeable persons named by case study contact workers, random sample, and institution CRD workers. Part One discusses extension projects within a framework of accountability, and Part Two presents findings regarding what extension CRD purports to do. Part Three examines how CRD resources are used and what kinds of programs are conducted. Part Four analyzes impacts of CRD projects dealing with problem solving, facilities and services, public policies and issues, and family income, while Part Five presents the positive and negative consequences resulting from CRD projects for communities as a whole, as well as for special interest groups. Part Six describes responses concerning community support for CRD, followed by the summary and implications in Part Seven. A bibliography of references for future evaluations, copies of questionnaires used in the study, and a descriptive statement of CRD work in the U.S. complete the report. (JD)
