The purpose of this study is to assess how studying abroad impacts the development of intercultural competence and the moderating role of student's personality. This research uses a pre-post design with a sample of 264 undergraduate students from four Colombian universities; it includes a group of students who participated in a one semester study-abroad program and a control group who did not travel. The average level of increase in intercultural competence for the students who went abroad was 0.511 standard deviations above the average of those who had not studied abroad. The results from hierarchical linear regression did not yield any evidence that supports the moderating effects of the personality factors on the relation between study abroad and intercultural competence.
