Approximately 700 questionnaires were mailed, and 365 usable responses obtained, in a study of persons who had inquired about the State University of Nebraska (SUN) spring 1975 telecourse offerings but who did not enroll. This working paper and executive summary compare the questionnaire respondents to SUN's fall 1975 learner population in terms of the demographic information requested on the questionnaire. These comparisons are presented in an effort to examine whether non-enrollees have attributes different in the aggregate from enrollees. The demographic information includes age and sex distributions, educational achievement, marital and family status, and job title or duties. Reasons cited for non-enrollment include the following: cost of tuition, personal daily schedule, lead time, cost of instructional kit, non-interest in courses, and "other" reasons. The non-enrollment questionnaire is appended. (LBH)
