The purpose of this article was to investigate the effect of Korean college students’ short-term study abroad on intercultural sensitivity according to their genders, grades, and experiences of living in different countries. Seventy-nine college students from various majors in P University participated in this study. They took a culture and language program in the Philippines, offered by their university, during their summer vacation. Chen and Starosta’s Intercultural Sensitivity Scale (ISS) was administered as pre- and post- questionnaires before and after studying abroad. The ISS is composed of five sections: interaction engagement, respect for cultural differences, interaction confidence, interaction enjoyment, and interaction attentiveness. Analysis of the data using t-test showed that the variables such as short-term study abroad, gender, grades, and experience of living in foreign countries have a statistically significant effect on participants’ intercultural sensitivity. The implications and limitations of this study were discussed.
