The second four-year follow-up study of the Jackson County Adult Evening High School Completion Program was made to determine the effectiveness of the program in terms of the financial, social, or personal gains of the graduates. The study concerns the graduating class of 1968 (111 graduates) fairly evenly distributed as to sex (40% men and 60% women). Data were collected by use of a questionnaire, with a return rate of 94.6%. A total of 104 completed questionnaires are used in the tabulations, presented in 30 tables. Conclusions of the study are: (1) Almost all the graduates remained in the local communities; (2) No participant has been prevented from graduating from high school because of being head of household, married, or working; some are continuing their education beyond high school; (3) Many have had job changes and promotions; (4) A significantly larger number of housewives have entered the labor market; (5) Almost twice as many reported income increases after four years compared with one year after graduation; (6) 80% of the income increases, job changes, or promotions were related to completion of high school in this program; (7) Some have had as many as five promotions or job changes; (8) Some have taken additional adult courses; (9) 52% in the labor force were better off financially; (10) Most reported being better off socially and personally. The questionnaire and accompanying letters are provided. (DB)
