The purpose of this study was to examine similarities and differences in students' capacities for socially responsible leadership as well as significant predictors of its development at a higher education institution in Mexico as compared with US schools. Results revealed that Mexican students both entered and left college with significantly higher capacities than their US peers. The collegiate environment contributed significantly to explaining student capacity in both cultural contexts, and leadership efficacy explained a greater amount of the variance in scores among students at the Mexican institution than those at US institutions.
