Abstract. The main purpose of this study was to examine the predictive validity of the system used for ab initio selection of candidates to a bachelor program in aviation. The selection includes paper-and-pencil tests, computer-based tests, and an interview. A total of 188 candidates participated in the validation study. The total test score predicted the results of three exams in aviation theory ( r = .27–.38) and extra flying hours needed (−.22), but not mean university grade. The regression analyses indicated that all predictors (tests and interview ratings) explained 25% of the variance in aviation theory, 19% in extra flying hours needed, and 7% in mean university grade. The overall findings confirmed the predictive validity of selection tests, especially the computer-based tests.
