Summary

Iltexas Houston Windmill Lakes Elementary is a public charter school in Houston, TX, serving 736 students in grades PK through 5, and is part of the International Leadership Of Texas (Iltexas) district.

This school has faced significant academic challenges, ranking in the 13th percentile statewide in 2025-2026, a slight improvement from previous years when it was in the bottom 3% of Texas schools. A key concern is its 5th-grade Science scores, where only 2.65% of students were proficient in 2024-2025, compared to the state average of 29.57%. Nearby Beta Academy, another charter school just 0.26 miles away, scored 25.17% in Science, highlighting the severity of the gap. However, there is a notable positive trend: African American student performance jumped from the 1st percentile to the 64th percentile in 2025-2026, suggesting targeted interventions may be working. The school also serves a high-poverty population, with 87.64% of students qualifying for free or reduced lunch.

Compared to nearby Pasadena Independent School District (Isd) schools, Iltexas spends significantly less per student—about $7,300 versus over $12,000 at schools like Laura Welch Bush Elementary (90th percentile). This funding gap likely contributes to larger class sizes (14.9:1 student-to-teacher ratio) and fewer resources. While the overall picture remains challenging, the 2025-2026 data shows modest improvement, with low socio-economic status students rising from the 1st to the 21st percentile. The school’s ability to sustain this momentum will depend on closing the resource gap and continuing effective strategies for its diverse student body.
