The Project „Student and Staff Mobilities in the Higher Education Sector” is compatible with University Development Strategy for 2021-2030 introduced by the Resolution of the University of Warmia and Mazury Senate on 29th 2021. One of the main objectives of the strategy is the increase of internationalisation of the University both on the national and international level. In order to achieve this goal, the University endeavors to suport and disseminate various domestic and foreign programmes for students and doctoral students as well as to participate in educational projects realised together with international partners. The ERASMUS+ KA131-2023 project constituted the main tool that supported the international cooperation and international mobilities of students and staff of the University of Warmia and Mazury.
