Abstract
Two experience-centered tests (derived from attempts to measure what workers may learn from jobs) and three requirements-centered tests (designed to measure the extent to which formally prescribed job requirements are met) were compared for 533 aviation and engine mechanics classified into 3 criterion groups: apprentice, senior mechanic, supervisor-technician. "Results of the earlier study [see 29: 6357] are thus corroborated: experience-centered tests again showed the higher relationships to the criterion.".
