Summary:
The three public schools in zip code 76093, serving the small community of Rio Vista, Texas, are all part of the Rio Vista Independent School District (Isd), which enrolls about 1,032 students across elementary, middle, and high school grades and holds a moderate state ranking in the 56th percentile.
Rio Vista High School is the clear standout, ranking in the top 31% of Texas high schools and boasting exceptional test scores—for example, 77.92% proficiency in Algebra I versus the state average of 54.03%—along with a 97.8% graduation rate and a very low 0.4% dropout rate. In contrast, Rio Vista Middle faces significant challenges, with its ranking dropping to the 49th percentile and critical weaknesses in 6th-grade Math (20.93% proficient vs. 38.57% statewide) and 8th-grade Social Studies (12% proficient vs. 31.69% statewide). Rio Vista Elementary falls in the middle, with scores generally below state averages but less severe declines than the middle school.
A key takeaway is the pronounced "middle school slump," where academic performance drops sharply after elementary, especially in Math and Social Studies. Interestingly, the high school, which performs best, has the highest per-student spending ($14,964), while the struggling middle school has the lowest ($9,916), suggesting resource allocation may play a role. The high school also stands out as a "value-add" institution, outperforming state averages despite serving a student body with over 55% economic disadvantage. Additionally, 8th graders at the middle school show extreme variance—64.36% proficient in Math but only 12% in Social Studies—pointing to a potential curriculum or instruction issue rather than a student problem.
