of Chicago attracted national headlines by becoming the first major research university to no longer require SAT/ACT scores from college applicants. Athletics The University of Chicago hosts 19 varsity sports teams: 10 men's teams and 9 women's teams, all called the Maroons, with 502 students participating in the 2012–2013 school year. The Maroons compete in the NCAA's Division III as members of the University Athletic Association (UAA).
