Effectiveness of an international health elective as measured by NBME Part II.

A total of 434 third- and fourth- year medical students from 80 U.S. medical schools participate between 1968 and 1974 in Yugoslav or Israeli international fellowship programs sponsored by the Association of American Medical Colleges and the U.S. Public Health Service. Subsequently, the scores of these fellowship student on Part II of the examinations of the National Board of Medical Examiners (NBME) were compared with the scores of rejected applicants and with the national average to determine the cognitive impact of the fellowship experience on the participants. The results show that the international fellows scored significantly higher than the rejected applicants and the national average in only the preventive medicine/public health portion of the examination. The conclusion is drawn that the fellowship programs enhanced the participants' knowledge of preventive medicine and public health.
