Intercultural communication has reached new levels with economic globalization, increased sophistication of communication technologies, and "internationalization" of education. As a critical tool for intercultural effectiveness, having a multicultural personality shapes the nature of interaction with people from other cultural backgrounds. In the university context, to advance internationalization, tertiary institutions need to be real international centers for teaching and learning with respect to people's world views. This study aimed to explore intercultural effectiveness of university students by using the Multicultural Personality Questionnaire (MPQ). With this purpose in mind, 493 students from the University of Notre Dame (ND), Sydney participated in a survey utilizing the MPQ. This study ascertained differences in dimensions of the MPQ for several demographic variables such as traditional (<24 years of age) vs. non-traditional (>24 years of age) university students, gender, religious affiliation, bicultural status, and level of study. This study confirmed significant differences in intercultural effectiveness across various countries as well as gender, non-traditional students, and bicultural study. It also stressed the role of curriculum changes at universities to strengthen intercultural effectiveness.
