Medical student self-assessment of performance on an obstetrics and gynecology clerkship.

Objective: The purpose of this study was to evaluate the accuracy of medical student self-assessment of performance on an obstetrics and gynecology clerkship and to assess the influence that demographic and temporal factors had on the accuracy of that assessment.

Study Design: From June 1990 to July 2000, 1152 students predicted examination and clerkship grades at the beginning and end of their obstetrics and gynecology clerkship. The effects of class rank, gender, rotation length, semester, prediction type, and timing on the accuracy of prediction were evaluated with logistic regression.
