The UTT couldn't make it without the Erasmus + program as it guides and finances almost half of our outgoing mobility for studies (about 300 each year) and to a lower extent for internships (about 60 each year). This support to mobility will become even more important as, considering the UTT’s will to internationalize its formations and the recommendations of the CTI (Commission des Titres d’Ingénieurs), UTT’s new study regulations state that all engineering students have to spend at least one semester abroad.
