Factor structure of the air force officer qualifying test form S: Analysis and comparison with previous forms

Due to its importance for assignment and classification in the U.S. Air Force, the Air Force Officer Qualifying Test (AFOQT) has received a substantial amount of research. Recently, the AFOQT was revised to reduce administrative burden and test-taker fatigue. However, the new version, the AFOQT Form S, was implemented without explicitly examining the latent structure of the exam. The current study examined the factor structure of Form S as well as its measurement equivalence across race- and sex-based groups. Results indicated that a bifactor model with a general intelligence factor and five content-specific factors fit the best. The measurement equivalence of the AFOQT across gender and racial/ethnic groups was also supported.
