In the context of an increasingly globalized society, this paper investigates the effectiveness of short-term study trips in enhancing intercultural sensitivity among Swiss university postgraduate students. Recognizing the crucial role of intercultural competencies in navigating both personal and professional life, this study focuses on the pedagogical value of week-long immersive experiences abroad. Using a pre- and post-test survey, we assessed changes in intercultural sensitivity following participation in two different study tours: one to Colombia and one to Malaysia. The surveys examined changes in several dimensions of intercultural sensitivity, including engagement, enjoyment, confidence, respect for cultural differences, and awareness. Results indicate significant improvements in country-specific intercultural sensitivity, particularly in areas that were actively engaged during the trips. However, improvements in general intercultural sensitivity were less pronounced, suggesting that while short-term trips can strengthen specific facets of intercultural competence, its impact on broader competencies may be limited or are only visible in the long-term. To enhance the educational impact of short-term study programs abroad, we recommend several strategies, which aim to deepen students’ intercultural understanding and ensure lasting benefits. This research contributes to the discourse on intercultural education by providing insights into designing effective short-term study programs abroad that foster globally competent and interculturally sensitive students.
