An important part of the University experience is participation in an active, democratically-governed student union. It is through the unions that student views are represented on all the major university committees, particularly regarding the academic and social life of the students. The union council members are elected once a year by all the students who are enrolled in the unions through cross campus elections held on a date set by the Hellenic Association of Student unions.
There are five undergraduate student unions at TUC, one per school, as well as an inter-school student union:
Postgraduate students from all postgraduate (Master's and Doctoral) programs at TUC have their own student association. Selected union council members serve as representatives.
The graduates of the School of Production Engineering and Management have formed their own union: www.mpd.gr
The graduates of the School of Environmental Engineering (now, School of Chemical and Environmental Engineering) have also formed their own union: www.enveng.gr
