Effect of quantitative feedback on student performance on the National Board Medical Examination in an obstetrics and gynecology clerkship

Objective The purpose of this study was to determine whether regular quantitative feedback improved medical student performance on the National Board of Medical Examiners Obstetrics and Gynecology subject test. Study Design We examined the effect of including regular quantitative feedback (in the form of biweekly quizzes) in the obstetrics and gynecology clerkship on student performance on the National Board of Medical Examiners Obstetrics and Gynecology examination at the University at Buffalo. Results Students who completed the clerkship format including the regular feedback scored significantly higher than students who completed the clerkship without feedback (70.3 ± 7.1 vs 68.2 ± 8.6; P < .005; mean ± SD; t test). The number of students failing the examination was significantly reduced from 6.39% to 0.47% (χ2 test; P < .001). Conclusion Introduction of regular quantitative feedback significantly improved student performance on the National Board of Medical Examiners test, and resulted in a significant decrease in the number of students failing the course.
