• Abstract:
  Previous research demonstrated that an empirically-keyed, response-option scored biographical data (“biodata”) ; scale predicted supervisory ratings of air traffic control specialist (ATCS) job performance (Dean & Broach, ; 2011). This research focused on the validity of scores on the Controller Background Assessment Survey (CBAS) ; in predicting an objective, computerized measure of en route controller technical skills. ; Method. The analysis was conducted in two steps. First, computerized aptitude test battery (“AT-SAT”) scores ; for 229 en route controllers were regressed on the Computer-Based Performance Measure (CBPM; Hanson, ; Borman, Mogilka, Manning, & Hedge, 1999). Second, biodata scores were entered into the equation. ; Results. AT-SAT scores accounted for 27% of variance in the criterion measure (β=0.520, adjusted R2=.271, ; p<.001). Biodata accounted for an additional 2% of the variance in CBPM (β=0.134; adjusted ΔR2=0.016, ; ΔF=5.040, p<.05). ; Discussion. The empirically-keyed, response-option scored biodata scale demonstrated incremental validity over ; the computerized aptitude test battery in predicting scores representing the core technical skills of en route ; controllers. Utility analysis suggested that even a small increment in validity was likely to have substantial ; organizational utility, given the high applicant volume and ATCS training costs. Further research to examine the ; relationship of CBAS scores to training outcomes at the FAA Academy and in field ATC facilities is ; recommended.
