The 2022 project within the framework of Erasmus KA131 - Mobility between Programme Countries - was carried out in accordance with the European Policy Statement and the internationalization strategy of Leuphana University Lüneburg. The overarching goal was to promote the mobility of students and university staff within the framework of structured mobility programs. New inter-institutional cooperation agreements were concluded with suitable partners in program countries and existing agreements were extended in order to ensure the quality of the measures and the recognition of the mobility phases for studying, teaching and the working environment. For the first time, Erasmus+ cooperation agreements were also concluded with universities in partner countries.
