This Erasmus+ project is part of the international and European strategy of EHESP school of public health, in line with one of the main orientations of its 2019-2023 strategic establishment project. The aim of this project was to support the demands of the various players involved in mobility at EHESP, in particular internship mobility, which is a key action for our students. These internships mobilities are an asset for raising the profile of EHESP and developing its network with companies, future recruiters of EHESP graduates students. The project also made it possible to support the academic and administrative staff for short periods of mobility, thereby encouraging exchanges of good practice and targeting staff who have not yet been able to take advantage of this opportunity. Finally, our aim was to keep internationalisation at the heart of our training programmes by integrating international initiatives on our campuses, in order to improve the quality of our teaching through the sharing of best professional practices and to continue to strengthen our international exposure, in line with the objective of capacity building and international cooperation.
