At SLU, there are approximately 4,900 students. Since SLU is spread across large parts of the country, there is at least one student union at each “main campus.” In total, there are seven unions at SLU, and Ultuna Student Union is the largest. The other unions are (from north to south): the Forestry University Student Union (SHS), the Veterinary Medicine Association (VMF), the Forest Management Student Union (SMS), The Equine Science Student Union (HAS), Alnarp Student Union (ASK) and the Union for Students of Agricultural and Rural Management (LMK). All seven student unions are members of a collaborative body called SLUSS (SLU's Joint Committee of Student Unions), through which the unions jointly address larger issues that affect the entire university, not just the parts of the university each union represents. The President and Vice President of SLUSS work full-time on these and other issues, representing students in SLU’s Board of Directors, the Rector’s Management Council, and numerous advisory bodies within the university’s central administration. Twice each semester, the SLUSS representatives from the unions (one student from each SLUSS union) meet to discuss and decide which issues should be prioritized, how the unions should position themselves on these issues, which union should represent students in various decision-making bodies, and at the different levels within SLU.

The primary task of SLUSS is to represent all students (undergraduate, master’s, and doctoral) at SLU in university-wide matters. This means they represent you as a student in, among other places, SLU’s Board of Directors and the Rector’s Management Council.

SLUSS has two full-time paid student positions that work on what is called student influence. It is the member unions that decide which issues should be addressed to the university and which students should represent students in everything from program committees to social and academic councils and faculty boards.
