Summary:
In zip code 75067 (Lewisville, TX), there are two middle schools serving grades 6-8, both part of the Lewisville Independent School District (Isd), which has a 3-star state rating.
Stem Academy At Hedrick Middle stands out as the higher-performing school in this area, consistently ranking above Marshall Durham Middle in state percentile rankings (25th vs. 10th percentile in 2025-2026). Hedrick outperforms Durham in nearly every subject and grade level, with the most dramatic difference in Algebra I: 77.08% of Hedrick students taking the Algebra I End-of-Course exam were proficient, significantly exceeding the district and state averages, compared to only 55.56% at Durham. This "Algebra I Anomaly" suggests Hedrick effectively accelerates select high-achieving math students, even as both schools struggle with general math proficiency—only about 7.7% of 7th graders at each school were proficient in grade-level math, roughly one-quarter of the state average.
Both schools serve a very high percentage of economically disadvantaged students (over 75% qualify for free or reduced lunch), yet Hedrick consistently achieves better academic outcomes, indicating its instructional strategies and programs are more effective at overcoming these challenges. Interestingly, Durham has a lower student-teacher ratio (11.1:1) than Hedrick (13.6:1), suggesting smaller class sizes do not automatically lead to better performance. A shared weakness across both schools is 8th-grade Social Studies, where only 15.95% of Hedrick students and 21.36% of Durham students were proficient in 2025-2026, well below the state average. Overall, while neither school is high-performing relative to the state, Hedrick Middle is the clear standout in this zip code, particularly for its targeted success in advanced math.
