Erasmus Student Network AISBL is a no-profit international student organization founded in 1990 by former students in International Mobility under the initiative of the Erasmus Bureau of the European Community, with the objective of representing the interests of students in international mobility.

ESN operates on three levels: international, national and local and, at the moment, it counts more than 500 sections in 40 countries with more than 18.000 active members that work on a volunteer base, providing services for around 150.000 Erasmus and non-Erasmus students.

The ESN sections work following the principle "Students helping students", in order to help the students making the most out of their study or internship period during their mobility.

The sections provide support both to outgoing and incoming students.

The volunteers are mostly students that already matured experience as exchange students and want to make their experiences available, or students that are about to make an international exchange experience and that through their job inside the organization can gain skills that may be useful to make the most out of the study experience abroad, even in countries with a social and cultural background that differs a lot from theirs.

On an international level, ESN promotes European student mobility interfacing with the major institutions of United Europe.

The executive body of ESN International is the Board, made up of 5 people and annually elected from among the members of the sections. The National Representatives of all the country members of ESN for the Council of National Representatives (CNR), which is the consultative organ and, in some cases, decision making body of Erasmus Student Network.

The decision making power belongs to the Assembly of the members, that gather every year at the Annual General Meeting (AGM).
