In this overview answers are looked for three questions: how well do cognitive ability tests predict work performance and do the results generalise to different countries, is there differences in the pre-dictive validity of cognitive ability tests between different jobs, and which is better predictor for work performance, general mental ability or specific cognitive ability tests. Both general mental ability and specific cognitive abilities are good predictors for work performance and results generalise to different countries. There were moderators for the association between gen-eral mental ability and work performance. Job complexity and publishing year of the research were moderators. Publishing year was moderator also for the association between specific cognitive abil-ity tests and work performance. There were no differences in the predictive validity of specific cog-nitive ability tests between different jobs. General mental ability was a better predictor for work per-formance than specific cognitive ability tests. The predictive validity of ability tests has been studied only in western countries so in the future it would be important to study do the result generalise also to different cultures. In addition it would be important to also study more the moderating effect of the year of publication. Is there really such an effect and if there is then it would be important to study why.
