MultiDiverse will design a new multidisciplinary highly integrated transnational EMJM in Multilingualism and Cultural Diversity by bringing together expertise from three EU universities and four disciplines in a complementary way. The University of Konstanz together with the Aristotle University of Thessaloniki, the Jagiellonian University, and with the input of academic and non-academic stakeholders will jointly design the curriculum and develop common processes and mechanisms related to quality assurance, accreditation, and recognition of degrees and credits. MultiDiverse will have a significant impact on the universities, future students, the European Higher Education Area (EHEA), and the society at large. It will enable the universities to develop a new partnership and improve the quality and innovation of their programmes; increase their internationalisation, competitiveness and attractiveness towards talented students; and set up new partnerships with academic and non-academic stakeholders. The innovative aspects of MultiDiverse will contribute to the attractiveness of the EHEA. The EMJM programme will train young talented people with a background in linguistics, education, psychology, or sociology on multilingualism and cultural diversity across disciplines to respond to the labour market needs within the academic and non-academic sectors. Students will obtain high-quality training, will become part of an international network, and will develop key competences that can significantly improve their employability. Training in digital skills and science communication will enable them to raise awareness of the opportunities and challenges of multilingualism and cultural diversity at national and local levels. This can lead to better understanding of multilingualism and cultural diversity by policymakers as well as the general public and can result in better understanding and implementation of policies on multilingualism and cultural diversity in Europe and beyond.
