Context/History of the project : The Ecole Nationale Supérieure d'Architecture Paris-Val de Seine (F PARIS129) leads an active international policy. The international development and the the inscrease of international exchanges (traineeships and studies) is part of the school priorities. The school maintains international relations since 1991 and the number of agreements never stopped increasing. Objectives : The long-term objective is to offer all students the opportunity to participate to a traineeship or study exchange at least once during its courses. This objective goes through an increase of the number of partner institutions and by an increase of the number of outgoing mobilities. Traineeships also offer a growing professionalisation of students and so the Ecole Nationale Supérieure d'Architecture Paris-Val de Seine (F PARIS129) considers the opporunity to increase the number of traineeship mobilities in the future. To offer an abroad experience to a maximum of students, the Ecole Nationale Supérieure d'Architecture Paris-Val de Seine (F PARIS129) decided to allow a maximum of one study or traineeship mobility during the whole course of study. Number and types of participants :The Ecole Nationale Supérieure d'Architecture Paris-Val de Seine organized a european mobility for 59 students during the 2014-2015 academic year. Those mobilities are divided as follows : 47 study mobilities and 12 traineeship mobility. The ones concerned by study mobilities were mainly Master 1 students (45 on 47), while the ones concerned by traineeship mobilities were mainly Master 2 students (9 on 12). Teaching mobilities are quite limited. 3 teaching mobilities were organized, two of them took place in Italy and one in Romania. Realized activities description : The principal realized activities were study mobilities (47), then traineeship mobilities (12), and finally teaching mobilities (3). Obtained results and impacts : Erasmus program mobilities made possible ECTS validations for all students from the Ecole Nationale Supérieure d'Architecture Paris-Val de Seine. Those credits were partially or completely obtained. Erasmus program departures were facilitated by the possibility for all students to benefit of travel grants. The three teaching mobilities also offered to activate or re-activate partnerships.
