Global preparedness is an ever growing concern for U.S. colleges and universities. In an attempt to offer cross-cultural exposure to students, short-term cross-cultural service trips are being offered as an alternative to study abroad. This option allows more students to participate in a cross-cultural experience at minimal expense and time. It has long been established that study abroad (generally one semester) impacts the student in a way that reflects an improvement in global preparedness. Very little has been examined on the impact of a short-term trip; defined as one to two week experiences. This paper examines the impact of a short-term cross-cultural service trip on dynamic (changeable, teachable) competencies that already correlated to success in a crosscultural work environment. These competencies include cultural flexibility, ethnocentrism, people orientation, and task orientation. The findings indicate that short-term cross-cultural trips positively impact cultural flexibility and ethnocentrism.
