This report provides a statistical summary (most of the volume) of the responses of the State University of New York (SUNY) constituent institutions to the biannual survey of non-credit instructional activities. The report is composed of three parts. Part I includes information on non-credit activities and registrations from a SUNY-wide perspective, from July 1, 1991 through December 31, 1991. Part II provides non-credit trend data from 1983 through 1991; and Part III includes a listing of all non-credit activities reported by SUNY colleges and universities from July 1, 1991, through December 31, 1991, by subject areas. Results show a substantial decline in the number of non-credit instructional activities and registrations at SUNY institutions in the fall 1991 time period, particularly at the community college level. In general, the reports show a 15 percent decline in the number of non-credit activities and a 17.5 percent drop in the number of registrations across the SUNY system, compared to those reported in the preceding 6-month period. The appendix includes a map of the locations of SUNY institutions and a chronological listing of when the institutions were established. Also provided is a publications list. (GLR)
