Crossborder curriculum partnerships are a relatively new and fast-growing form of internationalization in which the curriculum that has been developed by one institution (the home institution) crosses borders and is implemented in another institution (the host institution). These partnerships aim to provide comparable learning experiences to the students in both institutions and are driven by a variety of motives, such as strengthening international networks, increasing financial gains, and stimulating research spinoffs. Although popular, crossborder curriculum partnerships are also criticized for their potentially low educational quality, failing to address fundamental differences in teaching and learning between the home and host institutions, and not addressing the educational needs of the host country's health care system. Our aim is to provide guidance to those considering or engaged in designing, developing, managing, and reviewing a crossborder curriculum partnership or other forms of international educational partnerships in medical education. Drawing from research, personal, and institutional experiences in this area, we listed twelve tips categorized into four themes, which contribute to the establishment of sustainable partnerships that can withstand the aforementioned criticism.
