Summary:
The Lake Travis Independent School District (Isd) is served by a single, large comprehensive high school, Lake Travis High School, which educates students in grades 9 through 12 and has an enrollment of 3,569 students. This school is a standout institution in Texas, consistently ranking in the top 11% of all high schools statewide and earning a 5-star rating from Schooldigger for its overall academic excellence.
Lake Travis High School demonstrates exceptional performance in humanities, with over 80% of students proficient in English I and II Reading and over 90% proficient in U.S. History, far exceeding state averages by 18 to 26 percentage points. The school also boasts a strong graduation rate of 95.5% and a low dropout rate of 0.9%. However, a key finding is a notable weakness in Algebra I, where only 49.6% of students met proficiency in the 2025-2026 school year, falling below the state average of 54.03%. This is the only subject where the school underperforms compared to the state, suggesting a potential area for targeted improvement in math instruction.
While the school's state ranking has seen a slight decline over the past three years, dropping from the 92nd percentile to the 89th percentile, it remains a top-tier school. With a student-teacher ratio of 17.3:1 and spending of $8,574 per student, the school appears to be highly efficient, achieving outstanding results in most subjects. For parents, the primary takeaway is that Lake Travis High School offers a world-class education in English and history, but families should be aware of the specific challenge in Algebra I and inquire about the school's strategies to address this gap.
