The Project for Mobility in Higher Education in the Erasmus + Programme 2014-1-FR01-KA103-000343 contributed to implementing the international strategy of the Ecole Nationale Supérieure d’Architecture de Paris la Villette (ENSAPLV). Mobility in studies and internship for each student in the Master’s programme must represent an opportunity to take up the challenges of an international context. During the 2014-2015 academic year, 98 students from the school were involved in this project, corresponding to approximately half of the students primarily concerned by mobility, in the first year of the Master’s. Mobility of teaching staff is also highly encouraged by the school with the aim of providing an international opportunity to students who are unable to take advantage of a period abroad. 34 teaching mobility actions were carried out in the framework of this project. The Commission for International Relations, made up of some dozen teachers and two student representatives, and supported by the International Relations Service is in charge of preparation, oversight and valorisation of the mobility actions. Mobility actions developed by the ENSAPLV with its partners in this project enabled us to intensify the quality of reciprocal exchanges and should eventually make joint projects in cooperative teaching possible.
