Summary
Lacoste Elementary in La Coste, TX, serves 610 students in grades PK-5 as part of the Medina Valley Independent School District (Isd), a district ranked in the top 40% of Texas school districts. While the school has historically been a solid performer, its overall state ranking has dipped to the 52nd percentile in recent years, a notable decline from a high of the 82nd percentile a decade ago. However, Lacoste shows remarkable strength in serving specific student groups, ranking in the 73rd percentile for African American students and the 76th percentile for Multi-racial students, which sets it apart from nearby schools.
A key comparison is with Castroville Elementary, located just 4.93 miles away in the same district, which ranks in the 79th percentile (4 stars) and outperforms Lacoste in nearly every metric. For example, in 5th grade math, Castroville achieved 71.15% proficiency compared to Lacoste's 50%, and in 3rd grade math, Castroville reached 65.12% proficiency versus Lacoste's 38.98%. This is despite Castroville having a slightly higher student-teacher ratio (16.6 vs. 13.6) and lower spending per student, suggesting that factors like instructional strategies or community engagement drive its success. On a positive note, Lacoste has shown a promising turnaround in 5th grade math, with proficiency rates improving from 43.92% in 2023-2024 to 50% in 2025-2026, exceeding both district and state averages.
Lacoste's performance with English Language Learners (ELL) has been inconsistent, dropping from the 85th percentile in 2022-2023 to the 46th percentile in 2024-2025, indicating challenges in maintaining a consistent program. Despite its struggles, Lacoste significantly outperforms its nearest neighbor, Silos Elementary, which ranks in the bottom 26% of Texas schools with alarmingly low proficiency rates in 4th grade reading (31.01%) and math (30.23%). Interestingly, Lacoste has the lowest student-teacher ratio (13.6) among all Medina Valley ISD elementary schools, yet it still underperforms relative to peers like Castroville and Potranco Elementary, which have higher ratios. This suggests that Lacoste's challenges are more about instructional quality or addressing the needs of its higher-poverty student body, where nearly two-thirds of students are economically disadvantaged.
