Lake Travis High School competes in a number of academic and athletic extracurricular activities to provide enrichment opportunities for students. To participate, students must maintain academic eligibility. To do so, students must maintain a grade of 70% or higher in all academic subjects other than UIL-exempt or locally exempt advanced courses. 

Locally exempt advanced courses recognized by LTHS include all Pre-AP, AP, Honors, and Advanced Honors or dual credit dual enrollment courses in the subject areas of English language arts, mathematics, science, social studies, economics, or a language other than English, as well as, selected Honors courses as approved by the school board each year. Students should check with their coach/director or counselor for a list of selected locally exempt Honors courses. AP courses are exempt from eligibility requirements. Pre-AP and Honors courses are granted a waiver for eligibility. The waiver is applicable on a one-time basis per course, per semester.

UIL participants are eligible to participate in contests during the first six weeks of the school year provided the following standards have been met:

• Students beginning in grades nine and below must have been promoted from the previous grade prior to the beginning of the current school year.

• Students beginning their second year of high school must have earned five credits, which count toward state high school graduation requirements.

• Students beginning their third year of high school either must have earned a total of ten credits which count toward state high school graduation credits or have earned a total of five credits that count toward state high school graduation requirements during the 12 months preceding the first day of the current school year.

• Students beginning their fourth year of high school either must have earned a total of 15 credits which count toward state high school graduation credits or have earned a total of five credits that count toward state high school graduation requirements during the 12 months preceding the first day of the current school year.
