Summary:
In zip code 78039, there is one elementary school, Lacoste Elementary, serving grades Pre-K through 5th with 610 students in the La Coste area, part of the Medina Valley Independent School District (Isd).
Lacoste Elementary is the only school in this zip code, and it shows a mix of strengths and challenges. The school has a favorable student-teacher ratio of 13.6:1 and spends over $10,000 per student, yet its overall state ranking has declined from the 62nd percentile to the 52nd percentile over three years. A notable bright spot is 5th-grade math, where 50% of students scored proficient in the most recent year, outperforming both the district (46.29%) and state (47.38%). However, 3rd-grade math proficiency (38.98%) lagged behind the district (40.54%) and state (44.33%). The school also shows a "bilingual bump" in reading, with 3rd graders taking the Spanish STAAR Reading test scoring 37.5% proficient, significantly higher than the district (25%) and state (28.3%).
Performance across grade levels is inconsistent year-over-year, making trends hard to predict. For example, 4th-grade reading proficiency dropped from 53.61% to 43.93% between recent school years, while 3rd-grade math jumped from 38.98% to 50.63%. An anomaly occurred in the 2024-2025 school year when 0% of 3rd graders taking the Spanish Math STAAR were proficient, though the sample size was likely very small. With 63.61% of students eligible for free or reduced lunch, the school serves a predominantly low-income population. Despite adequate resources, the school's overall academic performance remains average, suggesting that more targeted instructional strategies may be needed to improve outcomes.
