THE PROBLEM OF SELECTION for the investigation. This choice will be determined in part by practical considerations and in part by the criterion of vocational success which has been agreed upon. The investigator then proceeds to determine at least pro- visionally the abilities most essential for success. This step is facilitated by having for observation the workers who have been chosen as subjects for the investigation. In the light of his analysis the investigator selects or devises psychological tests, questionnaires, rating scales, or other examinations which give promise of measuring these essential abilities. Under carefully controlled conditions the investigator next applies these means of measuring abilities to the subjects chosen for the investigation. At or before this stage of the research the reliability of the examinations should be determined. A test or rating scale which does not give the same results upon repeated trials is as unreliable for purposes of vocational selection as an elastic tape would be for measuring stature. After the reliability of the examinations has been ascer- tained, their validity as indicators of success in the vocation is determined. The investigator validates a measuring instrument by comparing his measurements with the cri- terion of vocational success. A device is valid and useful which yields measures so closely related statistically to the criterion of success that, knowing a person’s score, his degree of success in the occupation may be at least roughly foretold. The value of the examination depends upon the closeness with which it predicts the vocational success of the applicant. The next step in the research is to find what combination of the several examinations which have proved to be valid, yields a total score with a maximum predictive value. The investigator will then have to justify this battery of tests or other aids in selection by comparing its predictive accuracy with that of the methods of selection previously In use.
