Introduction: Since 2012, researchers have focused on understanding the relationship between grit and the successful completion of medical school1. This study seeks to determine how grit levels, measured by survey at matriculation, relate to first year medical school academic performance. This study also seeks to address the discrepancy concerning measurement of grit and implications of grit in medical students before and during COVID-19 and the shift from in-class to on-line instruction. Methods: The data from this study were collected from Wright State University Boonshoft School of Medicine (WSUBSOM), a Midwestern allopathic medical school in the United States. Data were collected from 117 medical students in the class of 2023 for the 2019-2020 academic school year. Grit-S scores and MCAT percentiles were collected and used in this study. A two-way analysis of variance (ANOVA) was used for each final exam grade to determine the main effects of Grit-S category, the main effects of MCAT percentile category, and the interaction between the two variables. Results and Discussion: Results suggest that there is no significant difference between the three Grit-S categories and final exam performance. Results also suggest that there is a significant difference between the three MCAT categories and scoring on the Origins Final Exam, the Human Architecture Final Exam, and the Staying Alive Final Exam. Conclusion: MCAT percentile, not Grit Score, is a significant predictor of academic success in medical school. Additionally, there is no significant association between Grit-S categories and MCAT percentiles categories.
