Summary:
The four public schools in zip code 78645, serving the Lago Vista community, are part of the Lago Vista Independent School District (Isd), a small, above-average district with about 1,887 students across grades PK-12 and a relatively low rate of economic disadvantage.
The standout school in the district is Lago Vista Middle, which excels in advanced math, with nearly 98% of 8th graders proficient in Algebra I—far exceeding the state average. It also outperforms state averages in 8th-grade reading and math. In contrast, Lago Vista Intermediate shows a significant weakness in 5th-grade science, where only 13% of students are proficient, though its overall state ranking has improved. Lago Vista High School is a "reading school," with strong English I and II scores, but its Algebra I proficiency is critically low at just 18%, and its state ranking has declined from the 71st to the 52nd percentile. Lago Vista Elementary shows mixed results, with 3rd-grade reading at the state average but math significantly below it.
The district's key challenge is a math gap: while the middle school's top-tier students master Algebra I, high school students struggle with the subject, suggesting a need to bridge the transition. Additionally, the intermediate school's science curriculum requires attention. Overall, the district offers favorable student-teacher ratios (as low as 12.6:1 at the middle school) and a strong graduation rate of 94.7%, but parents should note the stark performance differences between schools, particularly in math and science.
