Objective. To examine the relationship between the NAPLEX and Pre-NAPLEX among pharmacy graduates, as well as determine effects of pre-pharmacy, pharmacy school, and demographic variables on NAPLEX performance.

Methods. A retrospective review of pharmacy graduates' NAPLEX scores, Pre-NAPLEX scores, demographics, pre-pharmacy academic performance factors, and pharmacy school academic performance factors was performed. Bivariate (eg, ANOVA, independent samples t-test) and correlational analyses were conducted, as was stepwise linear regression to examine the significance of Pre-NAPLEX score and other factors as related to NAPLEX score.

Results. One hundred fifty graduates were included, with the majority being female (60.7%) and white (72%). Mean NAPLEX score was 104.7. Mean Pre-NAPLEX score was 68.6. White students had significantly higher NAPLEX scores compared to Black/African American students. NAPLEX score was correlated to Pre-NAPLEX score, race/ethnicity, PCAT composite and section scores, undergraduate overall and science GPAs, pharmacy GPA, and on-time graduation. The regression model included pharmacy GPA and Pre-NAPLEX score.

Conclusion. The findings provide evidence that, although pharmacy GPA is the most critical determinant, the Pre-NAPLEX score is also a significant predictor of NAPLEX score.
