Summary:
This analysis examines eight elementary schools in the 78213 zip code of San Antonio, Texas, serving primarily Pre-Kindergarten through 5th grade across four districts, where a high level of economic disadvantage (80% average free/reduced lunch rate) provides critical context for understanding academic performance.
The standout school in the area is Castle Hills Elementary, which ranks in the 88th percentile statewide (4-star rating) and dramatically outperforms district and state averages in reading and math, though it has the lowest free/reduced lunch rate in the zip code at 38.27%. In contrast, Compass Rose Dream is the lowest-performing school, ranking in the 4th percentile (0-star) with critically low test scores and an extremely high student-to-teacher ratio of 36.1:1. Olmos Elementary is a notable high-achiever despite an 84.77% free/reduced lunch rate, ranking in the 69th percentile (3-star) and often exceeding state averages, particularly on Spanish-language STAAR tests. The most dramatic turnaround belongs to Legacy Traditional - Basse Pri, which jumped from the 3rd to the 51st percentile in a single year, with 3rd-grade reading proficiency rising from 15.79% to 54.41%.
The five schools in North East Independent School District (Isd) show a wide performance range, from Castle Hills (88th percentile) to Dellview Elementary (12th percentile), while the two charter schools represent the extremes. The average statewide percentile for all eight schools is 34.4, well below the 50th percentile, indicating most schools here perform below state averages. The data strongly suggests a link between student-teacher ratios and performance, as the two highest-performing schools—Castle Hills (12.9:1) and Olmos (12.2:1)—have the lowest ratios, while Compass Rose Dream has the highest. Additionally, schools like Olmos and Arnold Elementary show significantly higher proficiency on Spanish-language STAAR tests, indicating strong bilingual programs effectively serving English Learner populations.
