Key Takeaway
Note that cognitive abilities and positive personality traits correlate positively with academic achievement across school levels.

This second-order meta-analysis synthesized 29 first-order meta-analyses to evaluate how student characteristics across developmental domains, including cognitive abilities, psychomotor skills, positive emotions, and positive personality traits, relate to academic achievement. The analysis included 71 effect sizes from students in kindergarten, elementary, and secondary levels.

The authors found a medium-level overall positive correlation between these developmental characteristics and academic success. Cognitive abilities demonstrated the highest correlation with academic achievement among all studied domains. While positive emotions and positive personality traits also showed moderate effects on achievement, the strongest correlations were observed specifically in kindergarten students. Correlations were reported as moderate for elementary and secondary levels.

Because this is a second-order meta-analysis of existing meta-analyses, the findings reflect broader trends rather than direct primary data. The results indicate that developmental factors are associated with academic outcomes, which may inform educational policy and practice. However, these findings represent associations only and do not imply a causal relationship between specific traits and student performance.

Understanding what helps a child succeed in school involves looking at more than just test scores. A large-scale review of previous studies found that student characteristics across several areas—including cognitive abilities, psychomotor skills, and positive emotions—all show a positive link to academic achievement.

While all these factors matter, the data shows that cognitive abilities have the strongest connection to success. Additionally, students in kindergarten showed the strongest links between their personal traits and school performance compared to those in elementary or secondary school. This suggests that early development is a critical window for student growth.

Even though emotions and personality traits had more moderate effects than pure cognitive skills, they still play an important role in a child's education. These findings suggest that schools should consider the whole child—including their emotional well-being and personality—when shaping educational policies and practices.

What this means for you:
Cognitive abilities have the strongest link to school success, especially during the early kindergarten years.

Common questions

Which student traits have the strongest link to school success?

Cognitive abilities showed the highest correlation with academic achievement among all the domains studied. While positive emotions and personality traits also showed a positive relationship with grades, their effects were described as moderate compared to cognitive skills.

Do these findings change based on a student's age?

Yes, the strength of the connection changes by grade level. The strongest correlations between student characteristics and academic achievement were found in kindergarten students, while elementary and secondary students showed moderate associations.

Do emotions and personality affect how well kids do in school?

Yes, both positive emotions and positive personality traits show a moderate positive correlation with academic achievement. This means that a student's emotional state and character play a role in their overall success in the classroom.

Student characteristics are widely recognized as significant correlates of academic achievement. Among these, attributes related to developmental domains-such as cognitive abilities, psychomotor skills, positive emotions, and positive personality traits-have been the focus of numerous meta-analyses. This study employed a second-order meta-analytic approach to synthesize findings from 29 first-order meta-analyses selected based on predefined quality criteria using the R-AMSTAR checklist, yielding a total of 71 effect sizes. Results revealed a medium-level overall relationship between student characteristics and academic achievement. Effect sizes varied significantly by educational level, with the strongest correlations observed in kindergarten, and moderate associations found at the elementary and secondary levels. Among the domains, cognitive abilities demonstrated the highest correlation with academic achievement, followed by positive personality traits and positive emotions, both showing moderate effects. The findings are discussed in light of existing literature, and practical implications for educational policy and practice are presented.
