Paris School of Business (PSB) is one of the most renowned business schools in France and possesses several international accreditations that show the quality of the institution. International is in the DNA of Paris School of Business and this is visible through different levels: its name and identity, its share of international students (about 1/4), its international partners and its mobility opportunities. The Erasmus+ scheme is indispensable and fundamental in PSB's internationalisation strategy. Holder of the European Charter for Higher Education (ECHE) since 2006, PSB has sent and received hundreds of participants within the framework of the Erasmus+ programme. This 2021 project had a very special meaning because it was the first convention for which we could start sending students to Europe quite easily following the Covid-19 pandemic. Most restrictions were already lifted, in particular for the second semester during which our outgoing students were abroad for their mobilities for studies. We wanted to give a new impulse to mobilities, particularly in favour of mobilities for studies because they are mandatory for some of our students.
