The deployment of Erasmus+ mobility activities at the Lycée Centre Sud , currently called Paulette NADAL, aims to maintain the establishment in the dynamic of international openness. Indeed, in axis 2 of its establishment project roadmap entitled "strengthening artistic, cultural and linguistic centers, the long-term objective of the establishment is to become an international high school through the creation of an international section within it. This ambition requires the preparation of its staff. It is also about offering internship mobility to overseas students so that they can enrich their training path. The internship in a foreign company allows them to gain know-how and professional skills through knowledge of how new businesses operate. It also allows you to gain interpersonal skills: students who sometimes do not know the European continent are thus led to adapt to a new cultural and linguistic environment. This immersion in a foreign company represents, in a word, added value in their Curriculum Vitae. This added value will be appreciated by recruiters for their access to professional life.
