UIL meaning in Sports ?

The University Interscholastic League (UIL) is an organization that creates rules for and administers almost all athletic, musical, and academic contests for public primary and secondary schools in the U.S. state of Texas. It is the largest organization of its type in the world.

Activities range from American football and cross-examination debate to mathematics and marching band competitions; however, the UIL does not administer Academic Decathlon competitions.

The UIL is under the governance of the Vice President for Diversity and Community Engagement at the University of Texas at Austin in Austin, Texas. Although the Texas Education Agency governs the activities of schools and school districts in Texas, the UIL does not report to TEA, but is instead a separate entity.
