The substitution work in the respective fields of study is the responsibility of the student representatives. These thus form the smallest unit within the student representation structure in Austria.
The student representatives consist of 3-5 persons, depending on the number of students, who are elected in a personal election in the course of the ÖH election. They take care of the concerns of the students of their study program (e.g.: StV Jus, StV Maschinenbau, StV Life Sciences, etc.) and actively lobby in curricular commissions for improvements in the daily study routine.
You can get in touch with your student representative via your university representative.
