In implementing this Erasmus+ project for CPGE and PPPE, our project was multifaceted. Below, we detail the objectives according to the different courses - Concerning PPPE: the main aim was to respond to a request from the State to offer international mobility opportunities for L3-PPPE students. For the 2023 agreement, in conjunction with the UPPA, we decided to support students on internships at a school in Bulgaria. We contacted and visited the school beforehand to ensure the feasibility of transportation and accommodation and to establish the framework for the internship with the Bulgarian school's administrators. We ensured the effectiveness of the virtual component before each of these mobility programs. - For CPGE programs: our objective is multiple: to enable CPGE students who are scholarship recipients and/or from rural areas to discover other cultures, to offer students professional opportunities in Europe, to participate in strengthening European identity and citizenship, to reduce gender inequalities in scientific fields in particular, and to increase the attractiveness of our CPGE programs, which allow students from the valleys of the Pyrenees, Gers, and Landes valleys to access selective programs, even though many do not want to study in large urban centers (Bordeaux, Toulouse) at age 18.
