Counterproductive academic behaviors (CAB) are a major problem for educational institutions all over the world. For this reason, to determine the potential predictors of CAB is relevant. After defining CAB and introducing a typology of seven CABs facets (i.e., cheating, absenteeism, plagiarism, deception, breach of rules, low effort, and misuse of resources), this study reports on a comprehensive meta-analysis carried out to estimate the relationships between CAB and its facets with the Big Five personality dimensions and intelligence. Results showed that conscientiousness (K ϭ 77, N ϭ 31,473, ϭ Ϫ.28) and agreeableness (K ϭ 56, N ϭ 24,436, ϭ Ϫ.14) were predictors of the student's propensity to engage in CAB. Conscientiousness also predicted the 7 facets of CAB, particularly absenteeism ( ϭ Ϫ.30), cheating ( ϭ Ϫ.34), misuse of resources ( ϭ Ϫ.32), low effort ( ϭ Ϫ.29), and breach of rules ( ϭ Ϫ.27). Intelligence showed a negative relationship with CAB (K ϭ 55, N ϭ 30,052, ϭ Ϫ.19), and it was the best predictor of deception (K ϭ 18, N ϭ 3,575 ϭ Ϫ.48). The educational level, the type of cognitive tests, and the intelligence factor assessed were relevant moderators of the validity estimates. The validity of a compound of conscientiousness, agreeableness, and intelligence was .42 for predicting overall CAB. Finally, we discuss the theoretical and practical implications of the findings.
