The developmental benefits of being a resident Assistant include several positive educational outcomes. This article explores the effects of being a resident assistant on intercultural effectiveness and socially responsible leadership over four years of college. This is a quantitative, longitudinal, multi-institutional exploration employing college student data from the Wabash National Study of Liberal Arts Education. Overall, resident assistants at liberal arts colleges scored significantly higher compared to peers at other institutions in the sample on both measures of intercultural effectiveness and on half of the socially responsible leadership measures. In addition, after controlling for a host of demographic and other pre-college influences, resident assistants exhibited a significantly higher score on the consciousness of self domain of socially responsible leadership. These findings and implications for research and practice are discussed.
