註釋 A study of over 700 Enroute and Terminal Air Traffic Control Specialist trainees revealed that different kinds of pre-employment, job-related experience had differential value for the prediction of training performance. In general, experience most directly related to air traffic control work was a positive predictor; experience related to communications and piloting was negative. It was also shown that for Enroute trainees only, a composite variable representing the sum of tower GCA, RAPCON/RATCC, and center experience had a statistically significant, but small, relationship with ratings of job performance. In contrast, aptitude tests were superior to the experience variables for the prediction of all training course performance measures of both types of trainees, with the exception of laboratory performance of terminal trainees.
