The Weighted Airman Promotion System WAPS determines promotions to non-commissioned officer NCO ranks within the U.S. Air Force USAF. The WAPS comprises a formula for weighting various components characterizing an Airmans readiness for promotion. Two standardized tests multiple-choice format, each having 100 items serve as WAPS components a a Specialty Knowledge Test SKT a measure of technical knowledge pertaining to the Air Force specialty AFS i.e., job to which the individual belongs, and b the Promotion Fitness Exam PFE a measure of general USAF knowledge covering topics such as history, customs, dress and appearance, resource management, and security. SKTs are specific to each AFS, but the PFE is given to all members of a given rank, regardless of AFS. This report provides the results of analyses conducted to address the criterion-related validity of the WAPS tests and the extent to which that validity might be reduced by repeated exposure of test content. The potential for differential item exposure effects by raceethnicity and gender is also examined.
