Summary
Mary Harper Middle in Dilley, TX, is a small, rural school serving 181 students in grades 6-8 within the Dilley Independent School District (Isd), where nearly 80% of students come from low-income households. After years of ranking in the bottom 10% of Texas middle schools, the school has staged a remarkable turnaround, jumping to the 38th percentile in the most recent data—its highest ranking in over a decade.
The school’s standout strength is 8th grade mathematics, where 71.88% of students are now proficient—far above the state average of 47.24% and tied with Pearsall J H, while significantly outperforming Frank Newman Middle (24.42%). This success is partly driven by an effective Algebra I program, which accelerated top math students. However, 8th grade social studies remains a critical weakness, with only 16.39% of students proficient—roughly half the state average. The school also excels in supporting its highest-achieving students, with its Gifted and Talented program ranking in the 89th percentile statewide, and has shown dramatic improvement in special education, jumping from the bottom 2% to the 60th percentile. With a low student-teacher ratio of 9.8:1, compared to 14.6:1 at Pearsall J H, the school offers a more personalized learning environment.
Despite these bright spots, Mary Harper Middle still lags behind state averages in reading and 6th/7th grade math, suggesting that while resources are strong—with per-student spending of $13,985—instructional strategies need further refinement. Encouragingly, recent improvements have been consistent across all student groups, indicating that the school’s turnaround is benefiting everyone equitably. For parents, this is a school on an upward trajectory, with clear strengths in math and targeted support for both gifted and special education students, but with room to grow in other core subjects.
