Summary:
In zip code 78017, there is one high school, Dilley High School, which serves grades 9 through 12 in the rural community of Dilley, Texas, as part of the Dilley Independent School District (Isd).
Dilley High School has a total enrollment of 258 students and faces significant academic challenges, consistently ranking in the bottom 15% of Texas high schools. The school's test scores are well below state averages in every subject, with the largest gaps in U.S. History (32.88 points below) and English II Reading (26.55 points below). However, there is a promising trend of improvement from the 2024-2025 to 2025-2026 school year, with Algebra I proficiency jumping from 8.47% to 40.82% and Biology from 30.65% to 44.9%. Despite low test scores, the school maintains a strong graduation rate of 94.4% and a very low dropout rate of 0.4%.
A key feature of Dilley High School is its favorable student-teacher ratio of 9.5:1 and high per-student spending of $15,600, both of which are better than state averages. Over 72% of students are economically disadvantaged, which provides important context for the school's performance. The combination of high resource investment and low academic outcomes suggests that the school's challenges are deeply rooted, but the recent test score improvements indicate that new instructional strategies may be starting to work. For parents, this school offers small class sizes and strong student retention, but academic proficiency remains a significant area of concern.
