Leeuwarden has several active student unions. Some of these unions are represented in the IBOS (Inter Bestuurlijk Overlegorgaan Studentenverenigingen, a combined consultative body of student unions). IBOS was set up to ease communication between town council, police and the student unions about managing the union buildings. It still fulfils this role.
The unions also help organizing several events and activities of Leeuwarden Studiestad. Many members of student unions volunteer during activities and events like the Leeuwarder Studenten Veldvoetbaltoernooi and Studenten Startspektakel Leip!
