Summary:
The Rio Vista Independent School District (Isd) is served by a single high school, Rio Vista High School, which educates 296 students in grades 9 through 12 in a small-town Texas setting.
Rio Vista High School stands out for its strong academic performance in several core subjects, significantly exceeding state averages in Algebra I (77.92% proficiency vs. 54.03% statewide), English I Reading (74.68% vs. 55.43%), and Biology (75.95% vs. 70.51%) for the 2025-2026 school year. The school also boasts an exceptionally high graduation rate of 97.8% and a very low dropout rate of 0.4%. However, performance is uneven; English II Reading is a clear weakness, with only 63.51% of students proficient, barely above the state average. The school’s state ranking has also been volatile, swinging from the 82nd percentile in 2023-2024 to the 69th percentile in 2024-2025, before rebounding to the 77th percentile in 2025-2026. This volatility is likely amplified by the small student body, where the performance of a single cohort can have a large impact on overall metrics.
Key metrics include a favorable student-teacher ratio of 13:1 and per-student spending of $14,964, indicating significant investment in each student. While the school shows impressive year-over-year improvement in Biology (+18 points) and Algebra I (+11 points), U.S. History proficiency dropped by over 10 points from the previous year. For parents, this means Rio Vista High School offers a small, well-funded environment with strong outcomes in math and science, but with notable variability in English and history performance that families should investigate further.
