This paper provides a composite picture of some recent studies of research, demonstration, and curriculum development programs. The primary focus is on three studies: "Assessing Vocational Education Research and Development" (National Academy of Sciences, 1976, COVERD Report, ED 128 754); Anthony H. Pascal, et al., "Federal Programs Supporting Educational Change, Vol. III, The Process of Change, Appendix D. Innovations in Career Education" (Rand, 1975, ED 108 328); and "An Evaluation of Vocational Exemplary Projects: Part D Vocational Education Act Amendments of 1968" (Development Associates, Inc., 1975, ED 109 475). Two other studies are used for comparison: "Report to the Congress: What is the Role of Federal Assistance for Vocational Education?" (Comptroller General of the United States, 1974, GAO Report, ED 105 132) and "Knowledge and Policy in Manpower: A Study of the Manpower Research and Development Program in the Department of Labor" (National Academy of Sciences, 1975, DOL/MR&D Report, ED 118 802). Each report is reviewed, including methods of research, findings, conclusions and recommendations, and a critique. All five reports are summarized in a table comparing and highlighting purpose, scope, data sources, findings, and recommendations. A synthesis of the reports is also presented. Recommendations for methods of evaluating future Vocational Education R&D programs conclude the document. A short bibliography is appended. (BL)
