Summary:
The Duncanville Independent School District (Isd) serves six middle-level schools—three intermediate schools for grades 5-6, two middle schools for grades 7-8, and one combined school for grades 6-8—with a total enrollment of 3,068 students and a district-wide challenge of high economic disadvantage, as over 80% of students receive free or reduced lunch.
Among these schools, J Herman Reed Middle stands out for exceptional Algebra I performance, with 87.1% of students proficient in 2024-2025, far exceeding the district average of 30.22% and the state average of 54.03%. G W Kennemer Middle also excels in reading, with 70.59% of 6th graders proficient, nearly double the district average. In contrast, William H Byrd Middle consistently underperforms, ranking in the 3rd percentile statewide by 2025-2026, with math proficiency as low as 0.69% in 7th grade. The intermediate schools—Glenn C Hardin Intermediate, H Bob Daniel Senior Intermediate, and Grace R Brandenburg Intermediate—generally score below district averages in math and reading, suggesting weaker foundational skills. Notably, Grace R Brandenburg Intermediate is the only school with any proficiency on STAAR Spanish exams, though rates are low.
Key metrics reveal that student-teacher ratios range from 12.2:1 at G W Kennemer Middle and J Herman Reed Middle to 16.4:1 at Glenn C Hardin Intermediate, while spending per student varies from $9,219 at H Bob Daniel Senior Intermediate to $11,808 at J Herman Reed Middle. Dropout rates are low but range from 0.4% at G W Kennemer Middle to 2.4% at J Herman Reed Middle. A district-wide trend shows declining state percentile ranks for all schools with available data, highlighting ongoing challenges. The standout Algebra I success at J Herman Reed Middle despite high economic disadvantage offers a potential model for improvement, while the consistent underperformance in intermediate grades points to a need for stronger early math and reading instruction.
