Created in 1910, University Interscholastic League (UIL) provides educational extracurricular academic, athletic, and music contests, and specifically for basketball, divides schools into Division I (large) and Division II (small) districts. Separate playoffs are held for each division in Texas.
As of 2015, the state semifinal and championship games for all classes in boys and girls basketball are held at the Frank Erwin Center on the University of Texas at Austin campus.
The UIL redraws regions and districts biennially to adjust for changing enrollment sizes of schools as well as new schools. The main redrawing of regions and districts takes place on Feb. 1 of even-numbered years. The changing districts and regions resulted in the 2008-09 Class AAAAA boys' basketball champion DeSoto from Region II defeating Cedar Hill from Region I. These schools are in neighboring districts in Dallas County.
The UIL Legislative Council approved an increase in ticket prices for all state championship events, starting for the 2015-16 school year. Basketball state ticket pricing for girls is $75 all-tournament, and for boys, $100 all-tournament. This is the first increase in ticket prices since 2000, the Dallas Morning News reports. The UIL also announced rule changes that allow three games per day in a one-day tournament scheduled on Saturday. Previously, two games were permitted.
