Summary:
In zip code 78645, there is one middle school, Lago Vista Middle, serving grades 6 through 8 in the Lago Vista Independent School District (Isd), with a total enrollment of 435 students and a favorable student-teacher ratio of 12.6 to 1.
Lago Vista Middle presents a mixed picture of strengths and challenges. The school excels in advanced mathematics, with nearly 97.5% of students proficient in Algebra I, far exceeding the state average. Reading scores are consistently strong across all grades, and 8th-grade social studies also outperforms the state. However, the school struggles significantly with 7th-grade math, where only 16.67% of students are proficient, well below the state average of 29.41%. This creates a "math paradox" where advanced students thrive while general math students, particularly in 7th grade, fall behind. The school has a 0% dropout rate and a relatively low economic disadvantage rate of 24.83%.
Despite these strengths, the school's state ranking has declined over the past three years, dropping from the 74th percentile (4 stars) in 2023-2024 to the 62nd percentile (3 stars) in 2025-2026. This downward trend is likely linked to falling math scores in 6th and 7th grades. Overall, Lago Vista Middle offers a strong literacy program and exceptional opportunities for advanced math students, but parents should be aware of the challenges in general math instruction, especially for 7th graders, which is the school's primary area for improvement.
