Predicting NAPLEX scores using student performance in the clinical skills laboratory setting

Many predictors of success on the North American Pharmacist Licensure Exam (NAPLEX) have been studied, but little information is available regarding the effect of assessments in the clinical skills setting on student success. One way to determine if these assessments affect NAPLEX success is to review student performance in clinical skills laboratory courses (termed patient care lab ["PCL"] at our institution), which incorporate such assessments.

Students (n = 88) enrolled in a four quarter PCL sequence completed several individual assessments (both knowledge and skills-based), including drug information (DI) quizzes/final exams, patient case presentations and associated critical thinking questions, and formal DI responses. Linear regression assessed the relationship between PCL assessments and NAPLEX scores. Statistical tests were performed using IBM SPSS version 22 with a p-value <0.05 considered significant.

While drug information responses were not predictive of total NAPLEX scores (p = 0.192), the patient case presentation and associated critical thinking questions predicted 31.1% of variability (p < 0.05).

Performance of one cohort of students on certain pharmacy clinical skills lab assessments was predictive of total scores on the NAPLEX. Students who struggle with assessments in the clinical skills lab setting may be targets for early intervention to help improve the likelihood of success. More research is needed to fully elucidate the relationship between assessments in the clinical skills lab setting and NAPLEX performance.
