A comparative study was made of responses to the four-year followup questionnaires of the classes of 1967-68-69 of Jackson County Adult Evening High School. The purposes were to reveal any significant differences between classes in their responses, to answer questions concerning the benefits received by high school graduation, and to obtain results that would make the conclusions drawn more valid than they might be for any single class because of the larger numbers involved. The three followup studies were compared on a question-by-question basis. Among the results obtained are the following: (1) the benefits (educational, social and/or financial) do not differ significantly among these classes, regardless of class size, year of graduation, age or sex; (2) the program enables a significant number of housewives to seek and find employment which they did not do prior to completion of high school; (3) a very significant number of graduates in the labor market experience job changes or promotions far in excess of what could occur by chance; (4) about 12% have received additional training beyond high school; (5) nearly 23% have studied some subject since graduation; and (6) there were no significant differences between classes or between men and women in the numbers reporting to be better off financially. Recommendations concerning use of the study, this and similar programs, and dropout studies are made. (For related document, see AC 014 268.) (KM)
