Summary:

The Medina Valley Independent School District (Isd) serves approximately 9,638 students across 9 schools, including 6 elementary schools, 2 middle schools, and 1 high school, and is ranked in the 59th percentile of Texas districts with a 3-star rating.

For parents, the standout school is Castroville Elementary, which is the district's top performer with a 79th percentile ranking and test scores well above both district and state averages, despite 52% of its students being economically disadvantaged. In contrast, Silos Elementary is the most concerning school, ranking in the 26th percentile with consistently low scores across all subjects, even though it has a similar poverty rate. The two middle schools, Medina Valley Middle and Medina Valley Loma Alta Middle, are exceptional for advanced math, with over 92% of students proficient in Algebra I, far exceeding the state average of 54%. Medina Valley High School is a consistent performer with a 94.2% graduation rate and strong scores in Biology and U.S. History, though its Algebra I scores have improved dramatically from 25.8% to 41.9% proficiency.

Key takeaways include a district-wide decline in state rankings over the past three years, suggesting slower improvement compared to other Texas schools. Science is a systemic weakness, especially in 5th grade, where only Castroville Elementary exceeded the state average. Interestingly, higher spending per student does not guarantee better performance, as Lacoste Elementary spends more than Medina Valley Loma Alta Middle but ranks lower. The success of Castroville Elementary despite economic challenges provides a potential model for improving underperforming schools like Silos Elementary.
