1955-1965 : After the independence of the countries of the Maghreb and Black Africa, came the establishment by the State of the THE OFFICE FRANCO-GERMAN FOR YOUTH (OFAJ) and the THE OFFICE FRANCO-QUEBEQUOISE. These organizations encouraged the multiplication of youth hostals in Europe, the internship opportunities, and the sessions of "Knowledge of France", later structuralizing our sector of language education. The CIS of Reims was the first language educational center of languages such as Russian, Chinese, Arabic, German, and many more.
1965-1972 : The idea of a new building to accommodate all the activities of the Center Saint-Exupéry was born in the minds of directors and the Mayor of Reims: The layout was in place and the funding was being sought in the State's socio-educationa programs. In January 1972, the new Saint-Exupéry Center opens its doors to a wider audience for the socio-educational, cultural, and leisure in the grip of the project of the Parc Léo Lagrange. The former building of the street Werlé takes the name of INTERNATIONAL CENTER OF RESIDENCE, featuring a larger space and greater expansion of its activities to host international exchange of language teaching.
