As soon as the Erasmus program was launched, the Institute of Political Studies of Bordeaux decided to take the opportunity of this new project to internationalize its studies which consisted back then in a three-year diploma. During the 90s, we have increased the number of our international partnerships; and in the 2000s, an academic year abroad was integrated to the five-year diploma of Sciences Po, the students going abroad during their second year at the Institute. From then on, international student mobility became the key action of the international policy of our Institute. With the structuration of the partnerships, the staff mobility was added to the activities. Since then, the objectives sought through the Erasmus program have been the broadening and deepening of student mobility, the students still being the main beneficiaries of our Erasmus actions: Sciences Po Bordeaux has secured a vast network of more than 120 international partners and offers about 250 mobility places to its students. This new partner seeking policy and that of the outgoing mobility have naturally been matched with a hosting and reciprocity policy as open as possible to our new partners: 172 students, mostly second years (17% at Master’s level), go abroad for an Erasmus + study mobility, while Sciences Po Bordeaux welcomes 135 international students at a Bachelor or Master’s level. To this day, the Institute considers that the main objectives linked to student mobility have been reached. On the long term, this durable experience of the Erasmus program has tremendously shaped the courses offered but also the staff at Sciences Po Bordeaux. All teachers and other administrative staff consider international mobility to be a chance for the students, to whom the internationalized character of Sciences Po Bordeaux is a strong motivational component for choosing to study at the Institute.
