The ASUO Student Senate is an 20-member elected body, ten of which are finance senators and ten of which are academic senators. The Senate is responsible for the allocation of the Student Incidental Fee a mandatory fee that every student must pay. This fee is assessed through a year long budget process and must be approved by the Senate, The ASUO Executive and the University President.

The ASUO Student Senate is committed to the belief that student government is an integral part of the educational experience at the University of Oregon. Because the Associated Students have an inherent interest in the operation and affairs of their University, the Senate has a duty to represent the interests of the ASUO before the staff, faculty, administration and State Board of Higher Education. To that end, Senate shall endeavor to represent the students professionally, ethically and in a manner deserving of the respect of the ASUO and the staff, faculty, administration and State Board of Higher Education.

The ASUO Student Senate shall act on matters relating to the allocation and appropriation of incidental fees. The Senate shall also represent the collective and constituent interest of students in all matters considered and/or any matters coming before a shared governance body of the University including departmental administrative channels relating to student personnel services, University administered housing, campus design, and University budgeting, except as otherwise provided for in the ASUO Constitution.
