Internationalisation has gained prominence in debates on higher education and can be analysed from different perspectives, including cross-border higher education. Cross-border higher education entails relevant challenges, namely regarding its quality. This paper intends to discuss, based on a literature review, the link between cross-border higher education and quality assurance, namely the role quality assurance may have in contributing to a quality cross-border educational offer. 79 documents (indexed in Scopus or Web of Science) published between 1998 and 2019 were content analysed. The results show that both internal and external quality assurance are relevant topics when discussing cross-border higher education and a means to stimulate the overall quality of this educational offer. Moreover, to be effective, quality assurance must rely on cooperation and mutual trust between importing and exporting countries, including their quality assurance agencies.
