“…Data from our pediatrics clerkship confirm the upward time-of-year trend in NBME scores identified in earlier reports for medicine, 4 surgery, 5,6 and obstetrics and gynecology clerkships. 7,8,10 Our findings also support the data of Hampton et al, 10 who reported that NBME pediatrics scores increased toward the end of the year (although nonsignificantly in their data).…”

“…The USMLE-1 is highly correlated with NBME scores, 6,11,14 and therefore was used as an appropriate preclinical baseline measure to control statistically for possible academic biases associated with time of year. [4][5][6]8,11 A departmental written examination was administered midway through each rotation. It was worth 15% of the final grade (results not reported herein).…”

“…This flat preclinical baseline suggests that time-of-year trends observed in other measures did not result from accidental confounding of time of year with academic ability. [4][5][6]8,11…”

“…Baciewicz et al 5 and Ripkey et al 6 reported a similar trend for the NBME surgery clerkship examination. Clark and Jelovsek, 7 Manetta et al, 8 and Smith et al 9 reported that mean NBME obstetrics and gynecology clerkship scores were higher later in the year; and Hampton et al 10 reported the time-of-year trend for NBME obstetrics and gynecology scores and for final grades in obstetrics and gynecology and pediatrics. In contrast to these results, the time-of-year effect on NBME psychiatry scores appears to be very weak 11 or nonexistent.…”

“…10 A common speculation about the time-of-year trend is that students coming to a given clerkship later in the year have an advantage because of generalized clinical experience and technical knowledge acquired during that year's previous clerkships. [4][5][6]8,10,11 When the NBME score is considered in computing the student's final grade, the time-of-year trend presents an interesting problem to the medical educator and the medical student. From one perspective, the trend may be accepted, and the student may be encouraged to capitalize on it, rather than fall passive victim to "the accident of scheduling."…”

We undertook this study to determine whether a decrease in the amount of time a third-year medical student spent in an obstetrics and gynecology clerkship would cause a decrease in the knowledge of the subject. We compared National Board of Medical Examiners (NBME) obstetrics and gynecology subject examination scores of 168 students at the University of Texas Medical Branch at Galveston completing an 8-week obstetrics and gynecology rotation or the 1989-1990 academic year to scores of 187 University of Texas Medical Branch students competing a 6-week rotation during 1990-1991. No significant change in the total mean NBME subject examination score in obstetrics and gynecology was noted after the decrease in rotation length. Passing scores were those greater than 445 points. The failure rate for those students who completed the 8-week rotation was consistent throughout the 1989-1990 academic year. In contrast, those students who rotated through obstetrics and gynecology during the 6-week clerkship in the first half of the academic year had a failure rate that was statistically higher than those taking the clerkship in the last half of the year. The length of the obstetrics and gynecology clerkship was shortened to 6 weeks without significantly affecting students' overall performance on the NBME obstetrics and gynecology subject examination. However, a greater percentage of students who completed the rotation during the first half of the year scored low on the NBME obstetrics and gynecology subject examination than did those taking the rotation and thus the NBME subject examination in the second half of the year.
