This monograph summarizes a doctoral study on the effectiveness and status of New Jersey's cooperative business education programs. The general hypothesis of the study was that compared to non-cooperative office education students, cooperative students will: (1) be employed sooner, (2) be employed in more responsible positions, (3) receive higher earnings, (4) be more satisfied with their jobs, and (5) be rated more highly by their job supervisors. Among the conclusions of the study were: (1) The cooperative office education programs benefited those students who wanted to begin working immediately after high school, (2) Cooperative office education did not appear to have an effect on the beginning salary, (3) Cooperative office education did appear to have an effect on salary increases received by beginning workers, (4) A high degree of job satisfaction was indicated by both the cooperative and non-cooperative students, (5) Employers were better satisfied with those beginning office workers who were cooperative office education graduates, and (6) Cooperative office education did not appear to have a significant effect on the quantity or quality of the work performed by the beginning office workers. Numerous recommendations are also included. (Author/JS)
