Summary:
Zip code 78255 in San Antonio, Texas, is home to two exceptional public schools—Aue Elementary (serving grades PK-5) and Garcia Middle (serving grades 6-8)—both part of the highly regarded Northside Independent School District (Isd) and serving a low-poverty, affluent community that consistently drives top-tier academic results.
Aue Elementary stands out as the top performer, earning a 5-star rating for three consecutive years and ranking in the 94th-95th percentile among all Texas elementary schools. It boasts a favorable student-teacher ratio of 13.9:1 and higher per-student spending ($9,621), with exceptional proficiency rates in reading (75.8%), math (74.1%), and 5th-grade science (60.5%)—all dramatically above state averages. In contrast, Garcia Middle is a consistent high-achiever with 4- and 5-star ratings, ranking in the 89th-92nd percentile among Texas middle schools. Despite a larger enrollment (1,360 students), a higher student-teacher ratio (17.4:1), and lower spending ($7,359), Garcia achieves remarkable efficiency, with 8th-grade science (78.9%) and Algebra I (87.5%) scores nearly doubling state averages. However, a notable anomaly is Garcia's persistent weakness in 7th-grade math, where proficiency rates (7.14% in 2025-2026) fall far below the state average (29.4%).
Together, these schools form a powerful "feeder pattern" of excellence, with Aue Elementary feeding into Garcia Middle and both dramatically outperforming district and state benchmarks. The low free/reduced lunch rates (14-19%) reflect an affluent community where resources and parental support are abundant, contributing to the schools' elite status. For parents, this zip code offers a seamless pipeline of high-quality education from elementary through middle school, with Aue providing a more intimate, investment-heavy environment and Garcia delivering exceptional efficiency and standout STEM results.
