Does job-related training performance decline with age?

The meta-analytic review presents the findings of a project investigating the relationship between age and job-related training outcomes. The analysis is based on 83 effect sizes derived from 6,610 individuals. Results showed poorer training performance for older adults. In general, older adults, relative to younger adults, showed less mastery of training material (r = -.26), completed the final training task more slowly (r = .28), and took longer to complete the training program (r = .42). Field samples generally showed smaller age effects than laboratory samples. Estimated training performance for average individuals at various ages is provided.
