Summary:
In zip code 78617, there is one middle school, Del Valle Middle, serving grades 6 through 8 with 895 students in the Del Valle area.
Del Valle Middle is part of the Del Valle Independent School District (Isd) and faces significant academic challenges. The school consistently ranks in the bottom 10% of Texas middle schools, with its percentile rank declining from the 10th percentile in 2023-2024 to the 6th percentile in 2025-2026. Proficiency rates on the STAAR exam are well below state averages across all subjects and grades. For example, in 2025-2026, only 20.25% of 6th graders and 38.26% of 8th graders were proficient in reading, compared to the state average of about 55%. Math proficiency is even lower, with just 4.49% of 7th graders and 23.17% of 8th graders meeting grade-level standards. The school has a high rate of economic disadvantage, with 86.26% of students eligible for free or reduced lunch, and spends $9,541 per student with a 15.6:1 student-teacher ratio.
Despite these struggles, there are notable bright spots. The school shows a remarkable "Algebra I Paradox": while standard math proficiency is very low, 85.71% of students taking the Algebra I End-of-Course exam are proficient, far exceeding the state average of 54.03%. This indicates strong success in accelerating top math students. Additionally, reading proficiency improves slightly from 6th to 8th grade, and the dropout rate is a low 0.6%, below the district average of 1.6%, suggesting the school effectively keeps students enrolled. These positive elements provide a foundation for potential growth, even as the school works to address systemic academic challenges.
