This study investigated the relationship between measures of college education and work performance for a cohort of 84 police officers over a 10-year period. College education variables showed a statistically significant relationship with promotions (average r = .31), and supervisory ratings of job knowledge (average r = .25). However, there was an inconsistent relationship with measures of disciplinary action. These patterns of relationships may indicate that college education is relevant to many aspects of police work but should not be assumed to predict all areas of job performance.
