To determine if a student's subjective clinical evaluation score (CES) correlates with United States Medical Licensing Examination (USMLE) Step 1 or Step 2, obstetrics/gynecology clerkship final examination or Medical College Admission Test (MCAT) scores.


The test scores for all students rotating at Texas Tech Health Sciences Center at Amarillo from 1994 to 2002 were obtained. Regression models were used to compare the CES and examination scores. The 10th percentile of the CES was statistically compared with each examination score as well as its 10th percentiles.


The mean scores for the 285 students were USMLE Step 1, 204.4; USMLE Step 2, 205.0; MCAT, 29.1; obstetrics/gynecology final, 86.0; CES, 88.5. Linear correlations were found between the CES and USMLE Step 2 (r = 0.26, p < 0.001) and the obstetrics/gynecology final (r=0.25, p<0.001). Students with a poor CES (<10th percentile) had lower USMLE Step 2 scores, (188.2 vs. 206.3, p < 0.001) and more examination failures (odds ratio [OR] 8.9 [2.3-33.9]) as well as both lower obstetrics/gynecology final examination scores (81.1 vs. 86.3, p < 0.001) and more clerkship failures (OR 14.2 [1.9-107.4]).


Students' subjective CESs correlate linearly with performance on both the USMLE Step 2 and obstetrics/gynecology final examinations. Poor CESs (< 10th percentile) predicted lower scores on the future standardized examinations studied.
