Influence of candidates' test selection on pass rates on examinations for certification by the Educational Commission for Foreign Medical Graduates.

BACKGROUND

Parts I and II of the National Board of Medical Examiners (NBME) examination were first offered to graduates of foreign medical schools in 1989 as an alternative to the Foreign Medical Graduate Examination in the Medical Sciences (FMGEMS). This study was designed to determine whether differences in pass rates and scores were related to differences in the populations selecting one or the other examination.

METHOD

(1) Combined pass rates on the FMGEMS and NBME in 1989 and 1990 were compared with pass rates in previous years. (2) The proportion of NBME takers in 1989 was compared with the proportion in 1990. (3) Respective pass rates on the FMGEMS and NBME in the first NBME administration in 1989 were compared with pass rates in 1990. (4) The percentage of repeaters taking the FMGEMS was compared with the percentage taking the NBME in 1989 and 1990. (5) The distribution of repeaters by number of previous takes was compared between the FMGEMS and NBME in 1989 and 1990.

RESULTS

(1) Combined pass rates were similar to the pass rates of previous years. (2) The proportion of NBME takers declined in 1990. (3) The pass rates for the FMGEMS were higher in both 1989 and 1990, but the difference in pass rates between the two examinations narrowed in 1990. (4) The percentage of repeaters taking the NBME was high in 1989 and declined in 1990. (5) The number of previous takes among repeaters was higher for the NBME than for the FMGEMS in 1989 and became equal in 1990.

CONCLUSIONS

Some students probably opted to take the NBME in 1989 in the belief that it might be easier than the FMGEMS, resulting in lower pass rates for the NBME. The NBME pass rates rose in 1990 after the differential pass rates had become public.
