The University of California Student Association (UCSA) is an active 501(c)(3) unincorporated association, purposed as a student association of all University of California (UC) students. Its charter states that it "shall exist to: serve the interests of the current and future students of the University of California and promotes ["sic"] cooperation between various student governments of the University and student organizations concerned with higher education." The Association is not a public agency, but its leadership is composed of representatives of UC student governments, which are "official units of the University" system (with one exception). UCSA participates in various aspects of the UC system's governance, notably including the selection of the student representative on the UC Board of Regents.
