Summary
Margaret B Henderson Elementary is a PK-5 public school in the Oak Cliff area of Dallas, TX, serving 337 students as part of the Dallas Independent School District (Isd), where over 93% of students qualify for free or reduced-price lunch. This school stands out for its remarkable "J-curve" of academic growth: while 3rd and 4th graders often score below district averages—for instance, only 24.39% of 4th graders were proficient in Math in 2025-2026—the school transforms into a powerhouse by 5th grade, with 84.62% proficiency in Reading and 78.57% in Math, far exceeding district and state levels. This pattern is unique among nearby schools like Jimmie Tyler Brashear Elementary, which shows more consistent performance across grades.
The school's greatest strength is its exceptional support for vulnerable students, ranking in the 95th percentile for Special Education and 90th percentile for At-Risk students in 2024-2025. This effectiveness is especially visible in 5th-grade Science, where 53.33% of students were proficient in 2024-2025, compared to just 22.94% for the district and 29.57% for the state—a 30-point advantage over the district and far ahead of the next best nearby school, Jimmie Tyler Brashear, at 32.31%. Additionally, the bilingual program excels, with 4th and 5th graders taking the Reading test in Spanish achieving 65.52% and 66.67% proficiency, respectively, significantly higher than district and state averages for Spanish-language test-takers.
Despite these successes, the school's overall state ranking has dipped from the 81st percentile in 2019 to the 57th percentile in 2026, driven by lower-grade struggles. However, this creates an opportunity: if the school can replicate its 5th-grade instructional strategies in earlier grades, it could return to top-tier status. Notably, Margaret B. Henderson is located just 0.43 miles from Academy Of Dallas, a charter school ranking in the 0th percentile, highlighting extreme variability in educational quality within a small area. For parents, this school offers a proven formula for upper-grade success, especially in Science and for bilingual and special education students, making it a compelling choice despite uneven early performance.
