ABSTRACT
This chapter examines that how established individual differences in personality and intelligence are related to academic performance (AP) and performance in the workplace (WP). It includes an exhaustive review of studies reporting significant correlations between ability tests and AP, and indicates that psychometric intelligence is the most established predictor of AP. The chapter examines the salient literature on personality and AP and reviews several empirical studies looking at the relationship between different indicators of AP and well-established personality traits. It shows that individual differences in intellectual competence cannot be entirely explained in terms of cognitive ability or psychometric intelligence, and personality traits are likely to play an active role in the everyday process determining not only future achievement, but also the development and acquisition of adult skills and knowledge. Psychometric intelligence may reflect what a person can do, whereas personality traits predict what a person is likely to do.
