Analyzing 213,259 adolescents across 30 countries via PISA 2022, this study found curiosity, perseverance, emotional control, empathy, assertiveness, and stress resistance each positively predicted science achievement, while cooperation showed a small negative link. Curiosity and perseverance were the strongest predictors. These trait-achievement associations were notably stronger in individualist societies, suggesting cultural context shapes how personality translates into academic performance.

This PRISMA-guided systematic review synthesized 14 studies (2020–2025) on Big Five/HEXACO traits and vocational outcomes in adolescents. Conscientiousness and Openness were positive correlates of career maturity, decision-making self-efficacy, and vocational identity in several studies, though Conscientiousness's effect often weakened or reversed once RIASEC interests or self-efficacy were added as predictors. Neuroticism (and its HEXACO counterpart, Emotionality) was the most consistent trait, reliably linked to greater decisional difficulty and career self-doubt. Extraversion and Agreeableness showed more selective associations, aligning with enterprising/social interests. RIASEC personality–aspiration congruence varied by culture (moderate in a collectivistic Asian sample versus low in a rural Latin American sample) though this contrast rests on just one study per context.

Study of 139 male Saudi pre-medical students found openness to experience and extraversion positively predicted performance on both academic writing (r=0.292, r=0.171) and oral presentations (r=0.310, r=0.205), while conscientiousness, agreeableness, and neuroticism showed no significant correlations. Writing and oral proficiency were themselves strongly correlated (r=0.500), suggesting shared cognitive processes. Findings support tailoring communication training around personality profiles (fostering curiosity and social engagement) rather than relying solely on traditional academic predictors like conscientiousness.

In 116 Indonesian psychology undergraduates, neuroticism was significantly positively associated with academic stress (r = 0.207), while extraversion (r = -0.331), agreeableness (r = -0.346), conscientiousness (r = -0.199), and openness (r = -0.366) showed significant negative associations. Openness had the strongest protective effect. Findings suggest sociability, empathy, discipline, and cognitive flexibility buffer academic stress, while emotional instability heightens vulnerability, extending Western personality-stress research to a collectivist educational context.

In 296 adolescents tracked over two years, student-teacher agreement on Big Five traits was highest for Extraversion (highly observable, low evaluativeness) and lowest for Neuroticism (less observable, more evaluative). Conscientiousness showed stronger agreement for girls than boys. Teachers consistently rated Extraversion, Openness, and (for girls) Neuroticism lower than students' self-ratings. Both personality traits and social competencies showed high temporal stability, with teacher ratings more stable than self-ratings, and agreement remained consistently low across the study period.

This study confirms that the Big Five personality factors are reliable predictors of significant real-world behaviors, such as academic performance and alcohol consumption. By testing two independent samples using three different assessment tools (including traditional verbal inventories and an experimental nonverbal measure) researchers found consistent behavioral patterns across all versions. These results provide strong construct validity for the Big Five model, demonstrating that these five traits are not just theoretical abstractions but stable determinants of complex human actions in social and cultural contexts.
