METKA, officially the Student Union of Metropolia University of Applied Sciences, is the student union that represents all students in Metropolia UAS. The main task of METKA is to look after and advocate student rights. This is done in many ways: having student representation within the university, helping student in problem situations and also lobbying outside of the university for political decisions that affect students’ lives.

In addition to advocacy, METKA does also other things such as organizes events and tutoring and offers sports services in cooperation with Zone Sports Services.
