The University of Valencia has been a leading institution in Europe in the implementation of Erasmus mobility programmes since the inception of the initiative nearly 40 years ago. The KA131 project represents the most significant internationalisation action undertaken by the institution. The 2023 project pursued two primary objectives. First, to maintain the University’s position of European leadership in terms of participant numbers, thereby continuing to be recognised as a quantitative benchmark within the Erasmus framework. Second, to enhance a range of qualitative dimensions in line with the objectives of the Erasmus Charter 2021–2027. These include ensuring the full and automatic recognition of learning outcomes; providing personalised support throughout all phases of the mobility process; guaranteeing transparency in the grading system; and offering clear, accessible information regarding the course catalogue. In addition, the project aimed to strengthen the dissemination of opportunities and results through digital platforms and institutional communication networks. Within the digitalisation framework, the University sought to accelerate the implementation of, and active engagement with, the Erasmus Without Paper network, thereby facilitating the digital management of mobility processes through the development of a dedicated application. A further key priority was to promote the inclusive participation of all sectors of the university community, with particular attention to students with fewer opportunities, in alignment with the horizontal priorities of the programme. The initiative also aimed to foster innovative short-term mobility formats, such as Blended Intensive Programmes (BIP), in collaboration with the FORTHEM alliance of European universities, of which the University of Valencia is a member. Other strategic goals included facilitating mobility across all study cycles, promoting staff training mobilities to enhance institutional internationalisation, and encouraging the use of sustainable modes of transport for mobility, thereby contributing to the sustainable development of projects. Additionally, the programme sought to ensure accessibility for participants from disadvantaged backgrounds in order to achieve a more equitable distribution of opportunities. Ultimately, the project aimed to deliver effective and high-quality mobility experiences, ensuring a high degree of satisfaction among students and staff, while enhancing the academic, professional, linguistic, and personal competences of participants. It also sought to consolidate international synergies—particularly within the framework of European university alliances—and to ensure transparent and efficient financial management.
