Summary:
The zip code 78645 in Lago Vista, Texas, is served by two elementary-level schools within the Lago Vista Independent School District (Isd), which together educate 802 students across a split campus: Lago Vista Elementary (Pre-K through 3rd grade) and Lago Vista Intermediate (4th and 5th grades). Both schools serve a relatively affluent population, with about 30% of students economically disadvantaged, and enjoy favorable student-teacher ratios near 16:1, suggesting smaller class sizes than many Texas districts.
Comparing the two campuses reveals distinct academic profiles. Lago Vista Elementary has a strong historical track record, ranking in the 96th percentile statewide a decade ago, but recent 3rd-grade scores show a split: Reading proficiency (53.39%) slightly exceeds the state average, while Math proficiency (32.2%) falls dramatically below the state average of 44.33%. In contrast, Lago Vista Intermediate is on the rise, jumping from a 2-star to a 3-star rating for the 2025-2026 school year, moving from the 45th to the 63rd percentile. Its 5th graders consistently outperform both 4th graders and state averages in Reading (69.7%) and Math (50%), but a critical weakness emerges in 5th-grade Science, where only 13.16% were proficient compared to the state's 29.57%.
Key takeaways for parents include the need to look beyond overall ratings. Lago Vista Elementary excels in early Reading but requires support in Math, while Lago Vista Intermediate shows strong 5th-grade performance but a significant gap in Science instruction. Since both schools share similar demographics, these differences likely stem from instructional strategies or curriculum rather than student background. The district's 3-star rating and 66th percentile ranking provide a solid foundation, but parents should investigate specific grade-level strengths and weaknesses to best support their child's needs.
