Best Public Schools in Zip Code 78617

The five public schools in zip code 78617 (Del Valle, TX) are all part of the Del Valle Independent School District (Isd), serving students from elementary through high school in a community where over 86% of students face economic disadvantages. Del Valle High School stands out as the strongest traditional option, with a 95.2% graduation rate and a low 1.2% dropout rate, despite ranking in the 14th percentile statewide. In contrast, Del Valle Opportunity Center serves a high-need alternative population with a 7:1 student-teacher ratio and $40,141 per student spending, yet struggles with a 63.5% graduation rate and 9.2% dropout rate, showing that intensive resources alone cannot overcome profound challenges.

Academic performance across the area is consistently low, with all schools ranking in the bottom 15% of Texas. Del Valle Middle is a notable outlier: while it ranks in the 6th percentile overall and has critically low math scores (e.g., only 4.49% proficient in 7th-grade math), its Algebra I End-of-Course exam saw 85.71% of test-takers proficient—far above the state average of 54.03%. This suggests a small, high-performing cohort is taking the test, not a school-wide strength. Del Valle Elementary and Popham Elementary both rank in the 12th-14th percentile, with 5th-grade science proficiency at Del Valle Elementary at just 0.92% compared to the state's 29.57%.

Key takeaways for parents include the stark contrast between Del Valle High School and the Del Valle Opportunity Center in graduation outcomes, and the "Algebra I anomaly" at Del Valle Middle that masks broader math struggles. Spanish-language STAAR tests at Popham Elementary show some relative strength, with 5th-grade Reading Spanish scores (35.14%) exceeding the state average (32.91%). Overall, the district faces systemic challenges in core instruction, with spending not correlating to performance, as seen in the Opportunity Center's high costs and low results.
