The Assembly of Representatives (ADR) is the highest representative body of the students of a school. It is formed by:

• The student body elected as representative to the Senate.
• The student body elected as representative to the School Board.
• The student body elected in the centre itself from among those studying undergraduate's and master's degree courses attached to the faculty or school.

The election process for this last block of members, i.e. the students elected in the centre itself from among those studying undergraduate’s and master’s degrees, is the responsibility of each dean or school director office. They determine the procedure, dates and scope of the election (groups, courses, degrees, etc.). In any case, the call for applications must consider the possibility that the number of elegible members may be between 25 and 100, which must be distributed proportionally according to the different undergraduate's and master's degree programmes that depend on the centre and the departments attached to it.
