Maturation and education improve Air Force Officer Qualifying Test (AFOQT) scores. Since the AFOQT is given at different educational levels for the several commissioning programs, differences, largely spurious, exist between the programs. To assess differences produced by maturation and education, the AFOQT was given to 415 Air Force Reserve Officers Training Corps (AFROTC) cadets in 32 institutions late in their senior year. Scores were compared with those of the same group as freshman or sophomores. Pilot score increases for the total group were about 20 percentile points, with the greatest gains (30 to 50 points) in categories which received light plane training as part of the AFROTC curriculum. Navigator/technical scores rose about six points for the total group, and about 30 points for Category 2 cadets whose initial scores were below the 75th percentile. Category 2 cadets had initial scores about 30 points higher than cadets in nonscientific programs (Category 3), and this difference persisted in the final testing. Known rank-ordering of institutions of freshman and sophomore AFOQT scores applied also to seniors. (author/ly)
