This study from the Community College of the Air Force (CCAF) evaluates the effectiveness of occupationally-related degree programs by using criterion-referenced performance indicators to measure the on-the-job performance of graduates. This study is designed to answer the question of whether there is a relationship between educational attainment and on-the-job performance. The study compared the amount of time required to reach the job rank of craftsman among different educational levels. The study sample was 3,767, 4.59% of the approximately 82,800 staff sergeants in the Regular Air Force who were on duty on December 13, 1994 and who had earned a craftsmen level between November 1993 and October 1994. Study results indicated that there were significant differences in the variance between the mean number of years from entry to craftsman skill level when measured by CCAF participation and educational levels. Findings include: (1) members with bachelor's degrees or higher averaged 8.43 years, associate degree holders averaged 8.72 years, those with some college averaged 9.2 years, and those with a high school education averaged 9.3 years; (2) graduates of CCAF programs achieved craftsman level earlier than those who participated in the courses without finishing, and participants reached the level earlier than those who did not participate in courses; (3) the same trend held when testing demographic factors such as race, gender, and marital status. This research project could be useful to civilian community colleges interested in measuring effectiveness of occupational programs. (KP)
