With the formation of the postgraduate convention doctoral students became an independent entity to represent doctoral students and to address their concerns, such as changes in the faculty regulations for granting a PhD, the student-supervisor agreement or the courses offered by the Graduate Academy. So far doctoral students have not been recognized as their own status group within the University. This convention closes the gap of the status of students and those in teaching positions in the "Mittelbau". It defends the rights and interests of doctoral students in the Faculty of Science and provides a forum for discussion.
The council sends an advisory member into the faculty's governing body, the "Fakultätsrat", and acts as an advisor in all issues of concern to the faculty's doctoral students. Beyond that, the council is free to engage whatever issues it deems relevant and may pronounce statements on relevant questions in University politics.
The fundamental institution of the postgraduate convention is the general assembly. The general assembly convenes at least once a year and offers all members to directly take part in university politics.
The Board of Representatives - consisting of five PhD students - is elected by and from amongst the general assembly. The board of representatives is lead by a chairperson and vice-chairperson, as agreed upon by the board. Speaking for the entire postgraduate convention, the board of representatives comments on the work of and makes recommendations to other university institutions. In very important cases, the board consults with the postgraduate convention first, and can appeal for a supernumerary general assembly. To advocate the postgraduates' interest towards the faculty of science more intensively, the board of representatives dispatches one advisory member to the faculty board meetings.
Further important institutions of the postgraduate convention are the task groups, which can be installed by both the board and the general assembly. Task groups usually serve a specific purpose that is defined upon installation, and compile progress reports and recommendations for the general assembly and the board of representatives. Every member of the postgraduate convention can be active member of any number of task groups, and thus directly take part in university politics.
