The University Interscholastic League offers the most comprehensive literary and academic competitive program in the nation.  The Hallsville UIL Academic teams are consistently regional champions with several state winners. HISD UIL Leaders offer more than any other UIL team in terms of activities, with high school, junior high, and elementary contests. All HISD students are encouraged to participate in UIL Academic contests.

These activities, which complement the academic curriculum, are designed to motivate students as they acquire higher levels of knowledge, challenge students to confront issues of importance, and provide students with the opportunity to demonstrate mastery of specific skills.
