A Study of the Relationship Between the PCOA and NAPLEX Using a Multi-institutional Sample

Abstract

Objective. To examine the relationship between the Pharmacy Curriculum Outcomes Assessment (PCOA) and the North American Pharmacist Licensure Examination (NAPLEX) using a large, multi-institutional sample of student scores. Methods. A matched dataset was obtained from the National Association of Boards of Pharmacy (NABP) consisting of examination scores for the 1,460 students who completed both the PCOA and the NAPLEX between 2012 and 2015 at six schools/colleges of pharmacy (S/COPs). Bivariate correlations were estimated for total and content area scores on both examinations. Students' total NAPLEX scores were predicted using linear regression models containing total and content area scores on PCOA and dummy variables for S/COP and year. Results. Students' PCOA total score and NAPLEX total score were significantly and moderately correlated (r=0.54). All correlations between PCOA and NAPLEX total and content area scores were significant. and ranged from r=0.22 to 0.56. Regression results showed pharmaceutical and clinical sciences PCOA content scores were significant predictors of NAPLEX total score while basic biomedical sciences and social/behavioral/administrative sciences were not. The PCOA total and content scores accounted for 30%-33% of the variance in total NAPLEX score. Conclusion. Student PCOA and NAPLEX total and content area scores were significantly correlated, which is consistent with the findings of previous research. The somewhat modest proportion of variance in NAPLEX scores accounted for by PCOA scores illustrates the need for use of additional performance measures when evaluating student preparedness for the NAPLEX. This study provides important baseline data that can be used by S/COPs for comparison with their own student data as well as by researchers seeking to conduct additional analyses following recent changes in the PCOA and NAPLEX blueprints.
