Three studies illustrate the uses of personality assessment methods for selection of Federal Aviation Administration (FAA) air traffic control specialists (ATCSs). Study 1, using a select-out approach to the problems of screening, compared the Sixteen Personality Factor Questionnaire (16 PF) results with NEO Personality Inventory-Revised (NEO PI-R) results from 122 student ATCS participants. Results suggest that the current approach to personality assessment during the initial medical examination focuses primarily on the extent to which the applicant reports symptoms consistent with neurotic, inefficient, and perhaps argumentative characteristics.
