title: Effect of a shorter clerkship on third-year obstetrics and gynecology final examination scores.
abstract: OBJECTIVE
  To determine if either a shorter third-year obstetrics and gynecology (Ob/Gyn) student clerkship or the semester of rotation results in differences in a student's objective or subjective performance.
  
  
  METHODS
  Five hundred twenty-one students from 1995-1998 (8-week clerkship) and 112 students from 1998-1999 (6 weeks) in their third year of medical school were included. Final examination scores, subjective assessments for the Ob/Gyn clerkship, final grades and United States Medical Licensure Examination (USMLE) Step 1 scores were obtained (first attempts only). Student t tests, chi2 and univariate analysis (using USMLE Step 1 scores as a control) were used (P <. 05) to compare the Ob/Gyn clerkship scores/grades by both clerkship length and semester of rotation.
  
  
  RESULTS
  The 8-week and 6-week clerkship mean final examination scores were 69.5 and 69.7, respectively; the USMLE Step 1 scores were 205.1 and 215.1, respectively (P < .001). After univariate analysis, lower examination scores were seen for students clerking on the 6-week rotation (P < .001) as well as for those clerking in the first semester (first semester, 68.1; second, 71.3; P < .001). Based upon these results, the 8-week clerkship scores were calculated to be approximately 3.4 points higher than those of the 6-week clerkship, potentially lowering the final grades of 15.2% of the 6-week students. No significant differences were seen with the comparisons of a student's subjective assessments.
  
  
  CONCLUSIONS
  A shorter third-year Ob/Gyn student clerkship appears to lower Ob/Gyn final examination scores. Lower examination scores are also seen for students with a first-semester clerkship. These lower scores could lead to lower final grades.
