Test Validation for 12,000 Jobs: An Application of Job Classification and Validity Generalization Analysis to the General Aptitude Test Battery.
Employment and Training Administration (DOL), Washington, DC. Div. of Counseling and Test Development.
This report cumulates the results of 515 validation studies carried out over a 45-year period by the United States Employment Service, and relates these findings to five systems of job classification and job analysis. Correction for sampling error shows that general cognitive, perceptual, and psychomotor ability are valid predictors of job proficiency for all jobs, though there is considerable variation in validity across jobs. Correction for sampling error shows that cognitive and perceptual ability are valid predictors of training success for all jobs and that psychomotor ability is a valid predictor for all but a few high-complexity jobs. The relevant information in each of the five job analysis systems turned out to be the same dimension: job complexity. This dimension has been assessed for all 12,000 jobs in the "Dictionary of Occupational Titles" and the validity generalization analysis performed here thus extends to all jobs in the current volume. Cognitive ability increases in validity as job complexity increases while psychomotor ability increases in validity as complexity decreases. Thus a shift in weight from cognitive ability to psychomotor ability across categories of job complexity produces average multivariate validity ranging from .49 to .59 for job proficiency and from .59 to .65 for training success.
