Cultural intelligence (CQ), an individual's capability to function and manage effectively in culturally diverse situations and settings, has become the focus of a vibrant scholarly conversation and a flourishing area of multidisciplinary research. Since the introduction of the concept in 2002, substantial research has been conducted concerning its definition, the validation of its measurement, and the examination of its development and predictive capabilities. The present paper systematically reviews 73 conceptual and empirical articles published on CQ from 2002 to 2015 in management and international business journals as well as in education and psychology. The authors discuss two distinct conceptualizations of CQ, developments within the conceptual research, and opportunities for further theorizing. They also cluster the empirical studies based on how CQ was used and identify patterns, achievements and challenges within the literature. Finally, based on their analysis, they identify promising avenues for future research and propose specific questions that can further advance the scholarly conversation on CQ.
