Abstract

Background: This pilot study compared performance of University of Calgary students on internal clerkship examinations with corresponding National Board of Medical Examiners (NBME) subject examinations.

Methods: Between April and October 2007, students completed internal and NBME subject examinations following six mandatory rotations. Local faculty within each discipline set the minimum performance level (MPL) for internal examinations. Two methods of standard setting were considered for NBME exams and a sensitivity analysis was performed. Corresponding internal and NBME examination scores were compared using McNemar’s discordant pair analysis.

Results: A significant and unexpected difference in failure rate between internal and external examinations was found in all clerkships. 1.4% of students were below the MPL for internal examinations and 27.3% (modified Angoff) or 25.9% (mean Hofstee compromise) (p<0.0001 for both) for the NBME. The proportion of students below MPL for internal examinations was also below the lower limit of the Hofstee compromise (14.4%).

Conclusion: Possible explanations include leniency bias in internal standard setting, discrepant content validity between local curriculum and NBME examinations, difference in student perception of examinations, and performance bias due to unfamiliar units.
