Our school's Erasmus charter enables our BTS international commerce students and some BTS management support students to do their end-of-first-year work placement abroad. This placement is an integral part of their training and is compulsory in the BTS CI. This project has several objectives: - to enable all students to go to Europe for their work placement, thus ensuring equal treatment, - to contribute to their professional training - develop their soft skills, in particular their adaptability, autonomy and employability, - apply the teaching content linked to business prospecting, - encourage further study, - promote the school's participation in European programmes, - provide training for teachers and administrative staff, - promote European citizenship for all, - finance part of the 2-month mobility. In addition, it enables teachers to exchange their teaching practices through mobility for teaching purposes. In addition, for the first time we have set up a BIP project with Rotterdam and Porto, to enable our students to work together on a joint project.
