The COVID-19 pandemic has profoundly impacted the education sector globally, yet its effects on GMAT test-taking patterns remain underexplored. This study systematically analyzes changes in the number of examinees and mean total scores during the pandemic, examining the association between COVID-19 metrics and these changes. Data from GMAT test reports and COVID-19 statistics across various continents were analyzed using the Wilcoxon signed-rank test and the Spearman correlation coefficient. Results indicate a significant decrease in examinee numbers in the early stages of the pandemic, with a negative correlation between new COVID-19 cases/deaths and annual examinee numbers. This trend is more pronounced among males than females. Mean total scores declined significantly during the early stage of the outbreak, yet no significant correlation was found between COVID-19 metrics and changes in scores. These findings highlight the pandemic’s substantial impact on GMAT testing due to exam cancellations and socio-psychological factors at the early stage. As restrictions eased, the effects diminished, suggesting no sustained changes in academic performance. This study enhances the understanding of the pandemic’s impact on GMAT dynamics, providing decision support and scenario foresight for policymakers to be more prepared for similar challenges in the future.
