Creativity predicts standardized educational outcomes beyond GPA and personality

• GPA (grade point average) and personality positively predict academic performance . • We used academic (GPA, standardized test scores) and creativity data from Australian students. • Creativity-related variables explained additional variance in academic test performance. • Performance on standardized educational tests is benefitted by student creativity. Despite popular stereotypes about schools killing creativity, most scholarship on academic achievement and creativity shows a positive relationship. The present study is an extension and conceptual replication of Kaufman et al. (2023) using the Australian National Assessment Program - Literacy and Numeracy (NAPLAN), including literacy and numeracy scores from Australian student participants ( Ns = 212 to 637, across analyzes). Using hierarchical regressions, we examined whether GPA, personality, self-reported creativity, intellectual risk-taking (IRT), divergent thinking flexibility, and verbal/math creativity predicted NAPLAN literacy/numeracy standardized scores. The addition of creativity-related variables (higher flexibility) explained an additional 7.5 % variance in NAPLAN literacy scores above GPA and personality, whereas an additional 9.2 % of variance was explained in NAPLAN numeracy scores by creativity-related variables (lower IRT but higher math creativity). These findings support the notion that performance on standardized educational tests is benefitted by student creativity; suggestions for future research with different standardized tests and creativity assessments, across cultures, are provided.
