The Geffen Academy Student Council (GASC) is the primary student-founded and student-run organization focusing on amplifying student voice on campus.
GASC consists of three committees. Each committee has nine representatives (3 seniors, 2 juniors, 2 sophomores, and 2 freshmen) that are voted on by their peers in an election the prior academic year. The GASC advisor is the Dean of Students and School Culture.
