The Royal College of Surgeons in Ireland (RCSI) was among the first medical institutions to establish a global education community which now provides high-quality transnational health professions education aligned across three locations: Europe, the Middle East and South-East Asia. The successful implementation of a shared modularized curriculum in this context can be complex and challenging. Here we describe our insights, gained from a decade of working together as shared module Academic Leads to deliver a system-based medical module to an international student cohort. The themes covered are some of the areas where we consider our joint deliberations have led to improved outcomes for the delivery and assessment of the module, which may be helpful to academic staff embarking on similar module sharing experiences.
