A number of ability tests were administered to 187 male job applicants ranging in age from twenty to fifty-three years. When test-performance was compared across age groups, no significant differences were found on tests of mental ability, numerical ability, reading speed and comprehension, and mechanical comprehension. On one of two verbal comprehension tests, scores increased significantly as a function of age. Moreover, the older individuals were not penalized in any way by tests which emphasized speed as opposed to power. The findings were discussed in connection with the generally negative stereotype of the aging worker.
