Aalto University Student Union supervises the interests of students and supports them in their studies and student life. Student advocacy is realized through local cooperation with the university, the municipalities, the student unions of the metropolitan area and other local officials. There is also the national aspect to student advocacy, which includes contributing to national decision making in parliament and the different ministries as well as affecting legislation.

The most important student advocacy related definitions of policy, such as those dealing with changes to the educational system and student financial aid, are made by the Representative Council. So, student advocacy work is based on the policy papers approved by the Council, which can then be further detailed by the Board if deemed necessary.
