Two studies were made of part time adult education enrollees in Wisconsin: (1) a Spring 1967 study of relationships between demographic or socioeconomic data and information on reasons for course participation in the vocational system; (2) a study during the 1967-68 school year in which questionnaires were given, to vocational system course enrollees, course dropouts and completers, and enrollees in five University of Wisconsin extension centers. These were among the findings: (1) participation in the extension and vocational systems differed significantly on sex, educational background (both higher for the extension group), and occupation and income; (2) vocational students were generally motivated by occupational and home tasks, while extension students stressed becoming better informed citizens and escaping daily routines; (3) newspapers (for the vocational students) and catalogs (for the extension group) were the leading sources of course information; (4) instructors in the vocational system appeared more empathetic toward their students than extension instructors.
