Promesa Academy Charter School

Promesa Academy Charter School is a single K-5 elementary school in San Antonio, TX (78207), serving 248 students as its own district, Promesa Academy Charter School.

This school is a standout for its consistently low performance, ranking in the bottom 6% of all Texas elementary schools (4th percentile in 2025-2026). Its district rank is 939 out of 951 (1st percentile), placing it in the lowest tier of Texas school districts. The school has a favorable student-teacher ratio of 12.1:1, suggesting smaller class sizes, yet academic outcomes are severely lacking. In the 2025-2026 school year, average Reading proficiency across grades 3-5 was just 33.36%, and Mathematics proficiency was only 21.02%—trailing state averages by 15-30 percentage points in every subject and grade level. The most alarming data point is that in 2024-2025, 0% of 5th graders were proficient in Science, compared to the state average of 29.57%.

Mathematics is a critical weakness, with only 13.64% of 3rd graders and 17.5% of 5th graders proficient in 2025-2026. Reading performance is volatile by grade level: while 4th and 5th grade reading improved between 2024-2025 and 2025-2026, 3rd grade reading declined from 37.74% to 31.82%. With 59.68% of students economically disadvantaged and spending of $12,661 per student, the low academic outcomes suggest the funds are not translating into student proficiency. The school requires urgent, targeted intervention, particularly in Math and Science instruction, to address these systemic issues.
