Summary
Castaneda Elementary is a mid-sized school in McAllen, TX, serving 374 students from Pre-Kindergarten through 5th grade as part of the McAllen Independent School District (Isd), a high-performing district ranked in the 74th percentile statewide. The school has a strong history of consistent performance, typically earning a 4-star rating, but its most recent overall ranking dropped to the 59th percentile, a notable decline from previous years when it ranked in the 74th-80th percentile range. This recent dip is a key point of interest, especially when compared to nearby schools like Milam Elementary, which maintained an 84th percentile ranking, and Rayburn Elementary, which improved to the 92nd percentile.
Castaneda’s most impressive strength is its exceptional performance with students from low socio-economic backgrounds. In the 2024-2025 school year, it ranked in the 93rd percentile statewide for effectiveness with this group, earning a 5-star rating—a remarkable achievement compared to nearby schools with similar poverty rates, such as Wilson Elementary (13th percentile) and Alvarez Elementary (47th percentile). The school also boasts a strong history in science, with 5th-grade scores in 2024-2025 (54.84% proficient) far exceeding district and state averages, and outperforming even high-performing neighbors like Rayburn Elementary. However, math performance is inconsistent: 4th graders consistently excel above district averages, while 3rd and 5th graders lag behind, a pattern not seen at nearby schools like Milam or Rayburn.
The recent overall decline appears driven by drops in performance for Hispanic and Special Education students, which fell from the 87th to 67th percentile and 78th to 64th percentile, respectively, between 2024-2025 and 2025-2026. Despite this, Castaneda’s per-student spending ($11,390) is above average but not an outlier, suggesting its success with low-SES students stems from effective resource allocation rather than total spending. The school’s ability to match the performance of higher-income schools like Milam in some areas, despite serving a population where 74% of students qualify for free or reduced lunch, highlights its potential. The primary focus for improvement should be addressing the inconsistent math scores and recent subgroup declines to return to its historically strong overall ranking.
