Institut Polytechnique de Paris (IP Paris) is a public scientific, cultural and professional institution that brings together five top French engineering schools: École Polytechnique, ENSTA Paris, ENSAE Paris, Télécom Paris and Télécom SudParis, as with 2 doctoral schools. IP Paris sets out to promote academic excellence, innovative research and the training of future leaders capable of meeting technological and societal challenges. As part of the E+ 2022 project, IP Paris has focused on the student mobility of training and doctoral mobility. This strategic choice aims to offer participants an enriching international work experience, while strengthening their employability and intercultural skills. Since the signing of the new E+ Charter in 2020, we have seen a significant increase in the number of participants in this mobility programme, testifying to its attractiveness and growing success. Since 2020, the Paris PI has seen a marked increase in the number of participants in the Erasmus+ programme. Each year, more than thirty students have been able to benefit from this opportunity, with mobility flows remaining stable.
