Summary
De Leon Middle in McAllen, TX, serves 664 students in grades 6-8 within the McAllen Independent School District (Isd), a district ranked in the top 26% of Texas. The school has shown a clear upward trajectory, moving from a 2-star rating to a consistent 3-star rating and climbing from the 36th percentile in 2022-2023 to the 59th percentile in 2025-2026. With 87% of students qualifying for free or reduced lunch, the school operates with a favorable student-teacher ratio of 11.8:1, suggesting a more individualized learning environment.
De Leon Middle stands out for its exceptional performance in Algebra I, with 94.64% of students proficient in the 2025-2026 school year—dramatically higher than the district average of 69.35% and the state average of 54.03%. This is particularly notable given the school's high poverty rate, which is significantly higher than top-performing peers like Morris Middle (45% economically disadvantaged) and Michael E Fossum Middle (60%). The school also excels at supporting specific student groups, ranking in the top 25% of the state for English Language Learner students (75th percentile), Special Education students (74th percentile), and Low Socio-Economic Status students (73rd percentile). This is a significant differentiator, as many schools struggle to achieve high outcomes for these groups simultaneously.
While De Leon's reading scores are competitive—often matching or exceeding the state average—Social Studies is a persistent weakness, with only 20.09% of 8th graders proficient in 2025-2026, well below the district (41.73%) and state (31.69%) averages. The school also shows a fascinating disconnect in math: while general 6th, 7th, and 8th-grade math proficiency rates are often below the district average, its Algebra I scores are world-class. This suggests the school is highly effective at identifying and accelerating top math students, but the broader math curriculum may need attention. Compared to its closest geographic rival, Sharyland North J H (1.49 miles away), which serves a wealthier student body, De Leon outperforms in 8th-grade Reading (64.16% vs. 59.32%) and has comparable Algebra I scores, showing it is effectively closing the achievement gap.
