École polytechnique, a public scientific, cultural and professional engineering school, has launched an Erasmus+ project for 2022-2023, focusing mainly on student mobility within the Engineering Cycle, including two-semester academic exchanges and 4-5 month internships. We also support the mobility of students in the Bachelor of Science program during their first semester of their final year of study, as well as internships for Master of Science and Technology (MScT) students, and finally staff mobility, all of which must meet the eligibility criteria defined by the School's International Relations Department. The number of supported exchanges has far exceeded initial forecasts, as well as the achievements of previous years, encompassing both study and internship exchanges. Each year, the exponential increase in the budget allocated to this project enables us to finance a growing number of students in their mobility projects. Overall, this project has contributed to the internationalization and skills development of Ecole Polytechnique students.
