The University Interscholastic League (UIL) is the largest inter-school organization globally, established in 1910 by the University of Texas at Austin. The UIL provides comprehensive educational, extracurricular, academic, athletic, and music contests for schools across the state.

The league manages extensive programs, including state championships in sports (like Volleyball and Cross Country), music (Wind Ensemble, Instrumental Chamber Music), and specialized events. Beyond contests, the UIL manages administrative functions, offering guides, waiver review boards, and legislative information. Partnering with MaxPreps.com, the UIL ensures that all team results and statistics are accessible to coaches and fans, reflecting its commitment to community and achievement.
