Acquiring intercultural competences is critical in order to avoid prejudice and increase tolerance in the global workforce. This case study describes and evaluates a learning experience designed to develop intercultural competences. Cross-cultural leadership theories were incorporated into the syllabus of a Work and Organizational Psychology (WOP) course. Students applied these theories while gaining international exposure through Online Intercultural Exchanges (OIE). Students from the University of Valencia (Spain) and the University Centre of Brasília (Brazil) participated in the exchange. The sample was composed of 22 undergraduate psychology students who worked in international pairs to address cross-cultural leadership. Results showed that students gained knowledge about cross-cultural leadership, developed intercultural competences, and evaluated the learning experience as satisfactory. These findings encourage the use of OIE to incorporate cross-cultural aspects in WOP.
