Summary:
This analysis examines seven elementary schools in the 78251 zip code of San Antonio, Texas, serving grades from Pre-Kindergarten to 5th grade, and reveals a stark performance divide between a single high-performing charter school and a set of traditional public schools with highly variable results.
The standout school is Basis San Antonio Pri - Jack Lewis Junior Campus, part of the Basis Texas charter network, which dramatically outperforms all others with test scores far above state averages—for example, 84.43% proficiency in 3rd Grade Reading versus the state's 51.08%. Among the six Northside Independent School District (Isd) schools, Raba Elementary is the top performer, consistently earning 4-star state rankings and achieving scores above district and state averages, particularly in Reading and 5th Grade Math. In contrast, Carlos Coon Elementary is the lowest-performing school, receiving a 0-star ranking for three consecutive years and placing in the bottom 9% of Texas elementary schools, with only 13.24% of 5th graders proficient in Math compared to the state average of 46.24%.
A critical finding is that 5th Grade Science is a universal weakness across all seven schools, with every school scoring below the state average of 29.57% proficiency in 2024-2025, including Basis San Antonio at just 11.76%. The data also shows a wide range in socioeconomic status, with free/reduced lunch rates from 51.33% at Raba Elementary to 83.18% at Carlos Coon Elementary, and spending per student varies from $9,289 to $10,782 among Northside ISD schools, though higher spending does not guarantee better performance. This creates a landscape where a family's address within 78251 can dramatically impact educational quality, with schools like Myers Elementary (67th percentile) and Murnin Elementary (56th percentile) falling in the middle, while Evers Elementary (40th percentile) and Lewis Elementary (56th percentile) show inconsistent results within the same district.
