As part of the international opening of our institution, we had the challenge to continue developing mobilities by raising interest: - Students to discover the world of business in Europe, - Teachers for language or Itwinning training which is enriching for them and becomes assets that benefit the whole community. We want our students and staff to be as immersive and connected as possible with Europe in order to create strong links with our outermost region. Observation of environmentally responsible practices in the host countries and professional practices integrating ecological principles on their site, training for staff and internship for students, to reflect on their behaviour and change it to contribute to sustainable development.
