This project is part of the internationalisation strategy pursued by Mines Paris-PSL for several years. We encourage our students to undertake study periods and traineeships abroad and develop these opportunities through our cooperation and double-degree agreements with European and international institutions. The project’s main objective was to support student and staff mobility. For students, the Erasmus+ programme is an important means of developing their academic, technical, professional, linguistic and intercultural skills. It allows them to discover different teaching and working methods, broaden their perspectives and gain a better understanding of European values and identity. For staff, teaching and training mobility opportunities provide a means of exchanging administrative and educational good practices and modernising our processes. They also encourage the development of innovative teaching methods and help establish or sustain academic and scientific collaborations by providing access to leading academic networks. Through this project, we therefore aimed to promote international exchanges within the university, improve the support provided to participants and strengthen long-term cooperation with our European and international partners.
