This article reports the results of a study inquiring about the role of education-related factors in the development of cultural intelligence. Five hundred fifty-seven students of a Colombian international business (IB) undergraduate program participated in the study. The psychometric properties of the measures were assessed by conducting exploratory and confirmatory factor analyses, and by calculating the corresponding reliability coefficients. T-tests and ANOVA analyses were carried out to test the hypotheses of the study. The results of the study suggest that second language proficiency, multicultural team membership, and participation in curricular and extracurricular activities promote the development of the cultural intelligence of undergraduate IB students.
