Seven papers investigated the effect of sex on MMI score. Four papers examined medical school admissions; two, nursing school admissions; and one, pharmacy admissions. Two papers identified a significant impact of sex on MMI score, while the other four did not.
Leduc et al (2017) found that female students performed significantly better in MMI’s for three French-Canadian medical schools than their male counterparts, but only in the subgroup that spoke French at home (p=0.003). This implies a previously unexplored interaction between sex and language, which warrants further study.
