As part of the Key Action 131 2023 project, Université Côte d’Azur (UniCA) continued its commitment to international openness by placing student and staff mobility at the core of its global development strategy. Coordinated by the Directorate for International and European Development (DDIE), the project aimed to support four main types of mobility: study, traineeships, staff training, and teaching assignments. A key objective was also to optimize the use of the financial allocation granted. This edition was marked by the coordination of seven Blended Intensive Programmes (BIPs), each bringing together up to 20 participants, demonstrating UniCA’s strong commitment to diversifying mobility formats and fully embracing the innovative tools offered by the Erasmus+ programme. Hybrid and short-term mobilities, already initiated in previous years, were further strengthened. By the end of the project, 264 mobilities had been implemented, including 193 student mobilities and 71 staff mobilities. Despite these solid results, the total number remained below the initial target of 490 mobilities. From a financial perspective, performance was notable, with over 94% of the allocated funds consumed—particularly for individual support costs. This imbalance between the number of mobilities and the level of budget expenditure is largely explained by UniCA’s strategic decision to apply the highest possible grant rates by region, in order to provide adequate and fair financial support to students. This assessment highlights the challenge of aligning the number of mobilities with the available financial resources. In the coming years, a more targeted strategy will be required to better balance qualitative ambition with quantitative objectives. Expanding the use of more flexible and cost-efficient mobility formats, such as BIPs, hybrid, or short-term mobilities, appears to be a promising path forward.
