University College Dublin has participated in Erasmus mobility since the beginning of the programme, and the university has continued its participation under Key Action 1, supporting the mobility of its students and staff. Through its participation, UCD aims to provide a suite of international opportunities which will create a unique international perspective for UCD degree programmes. Because of its long engagement with Erasmus mobility, UCD already has a large network of European partners, among them some of the leading institutions in the world. The Erasmus programme supports integrated mobility windows in many of UCD's degree programmes, across almost all disciplines, allowing students to select their studies with the clear intention of spending time abroad as part of their final qualification. Our staff mobility opens up opportunities for professional development, enhanced international collaboration and sharing of best practice for UCD faculty and staff. Student and staff mobility started to returning to pre-pandemic levels during 2021 and is expected to grow further in the following years. This mobility supports universitywide collaboration, including University Alliance activities, research and joint programmes.
