Summary:
Zip code 78039 is home to a single school, Lacoste Elementary, a public school serving grades PK through 5 with 610 students in the Medina Valley Independent School District (Isd), which is ranked in the 59th percentile statewide.
Lacoste Elementary shows a mixed performance profile with a notable downward trend. The school's state ranking has dropped from the 62nd percentile in 2023-2024 to the 52nd percentile in 2025-2026, a decline of 10 percentile points. While the school has strengths in 4th Grade Reading and 5th Grade Mathematics—where it outperforms both the district and state averages—it struggles significantly in 3rd Grade Mathematics, where proficiency (38.98%) lags behind the state (44.33%). This persistent "3rd Grade Math Wall" is a key concern, as foundational skills are built at this level. The school also administers STAAR Spanish tests, and data shows 0% proficiency for 3rd graders taking Math in Spanish, indicating a critical need for targeted support for English Language Learners.
Despite a favorable student-teacher ratio of 13.6 and per-student spending of $10,065, the school's academic performance is declining. With 63.61% of students eligible for free or reduced lunch, the high poverty rate likely impacts student readiness. The bright spot is 5th Grade Math, where the school (50%) surpasses both the district (46.29%) and state (47.38%), suggesting that upper elementary instruction effectively closes gaps. Overall, Lacoste Elementary is a school in transition, with resources in place but facing challenges in early math and supporting its diverse student population.
