This paper reviews work completed during the second year of a three-year project on postsecondary learning opportunities for adults. Background information includes perspectives on adult learning, issues of scope and definition, and a brief review of Postsecondary Education Commission projects related to project objectives. A review follows of important state and national studies on adult educational activities. Areas discussed include the participation rate; demographic variables that influence participation; differences between actual and would-be learners; reasons for participation; barriers to participation; subjects studied; choice of instructional methods, services, and resources adults would like to have available; preferred location and time; importance of credit; sources of instruction; and funding sources. A 1981 survey of California adults to determine their learning activities and interests is then reported. Results are compared with national and state surveys and with a 1974 survey of California adults. The final section presents these observations about adult learners: they are not a homogenous population; they behave in a highly traditional manner; and their attitudes keep them from participating in education. Issues that may serve as the basis for policy discussion are identified. (YLB)
