This paper aimed at investigating the relationship between HEXACO personality traits and academic performance in two samples of Italian 10–14 years old middle-school adolescents (N = 714 and N = 1093) using Multilevel Mixed Models. The main results show that: 1) Conscientiousness and Openness to Experience were the most important predictors of school performance, followed by Honesty-Humility; 2) a modest effect was present also for eXtraversion and Emotionality; 3) these influences occurred net of the influence of gender and class and could be generalized to male and female adolescents across 6th, 7th and 8th grade; 5) Perfectionism, Diligence and Prudence within Conscientiousness, Inquisitiveness within Openness, and Sincerity within Honesty-Humility were the facets more correlated with school performance; 6) results were replicated in two studies. Results are discussed and conclusions are drawn.
