With 50% international students and PhD students and 25% international teaching staff, Telecom Paris is an institution open to the world. And open means understanding, inclusive, diverse and cultured. International mobility is a perfect opportunity to acquire all these values. We therefore develop our international development strategy by being at the heart of academic exchange networks. The Erasmus programme is an essential part of this policy. Thanks to our Erasmus partnerships, students and staff, both incoming and outgoing, experience international life. We are convinced that mobility is a factor of development and enrichment and, as such, we motivate students and staff to have an international experience. In this way, they can take advantage of the best of the exchange institutions, increasing their level of qualifications and skills, and benefiting from the maturation that mobility brings. It is by having multicultural profiles, aware of multinational issues that Telecom Paris will continue to be open to the world.
