On a faculty level, there is the Faculty student council (FSC), and as the name might suggest, every faculty has one. They have a say in things the faculty board wants to implement. They also try to help program committees do their job. Explore the other menu items to read something about each faculty student council.
Besides the FSCs, there are also the Faculty Assessors. They are essentially the bridge between the students and the Faculty Board. Similarly to the FSCs, these are present at each faculty, but they also get together on a central level, which then forms the board of assessors.
