Research on 'heritage/community language education' (HCLE) has a relatively recent trajectory, but it has generated a large number of scholarly publications, particularly in relation to Spanish in the United States (U.S.) where the growth of Spanish heritage language learners (HLL) has been exponential. However, to date, limited research attention has been given to the intersection between heritage language learning and the development of intercultural communicative competence (ICC). This may be attributed to the assumption that, on a daily basis, such learners are required to move and effectively operate between languages and cultures and, therefore, already possess adequate levels of ICC. With the development of ICC, now considered an integral component in language education, the time appears ripe to examine its implications within HCLE. This paper articulates the key similarities and differences in the trajectories of ICC research in relation to university level heritage learners of Spanish in three distinct geographical contexts: Australia, Europe, and the United States.
