The Kentucky High School Athletic Association boys' and girls' state basketball championships are single elimination tournaments held each March featuring 16 high schools. Colloquially known as the Sweet Sixteen, the tournament takes place over 4 days at Lexington's Rupp Arena for the boys until 2014 and Bowling Green's E. A. Diddle Arena on the campus of Western Kentucky University for the girls until 2011. The state tournaments begin with District tournaments at sites across the state, district winners and runners-up advance to sixteen regional tournaments with the Regional Champions advancing to the Sweet Sixteen. Seeding for the Sweet Sixteen is determined by a blind draw, broadcast on statewide television.
Since its 1918 inception the Sweet Sixteen has built a legacy that includes dynasty teams and dramatic underdog stories. The tournament is particularly noteworthy in that it is only one of three state tournaments without a class system dividing small schools and larger schools into separate championships.
