This study looks at the effects of education level on job performance in 2 ways. First, it provides a meta-analysis on the relationships between education level and 9 dimensions of job behaviors representing task, citizenship, and counterproductive performance. Results here show that, in addition to positively influencing core task performance, education level is also positively related to creativity and citizenship behaviors and negatively related to on-the-job substance use and absenteeism. Second, we investigate the moderating effects of sample and research design characteristics on the relationships between education and job performance. Significant results were found for gender, race, job level, and job complexity. The article concludes with implications for future research and the management of an increasingly educated workforce.
