Summary:
In zip code 78225, there is one elementary school, Charles Graebner Elementary, serving grades PK through 5 as part of the San Antonio Independent School District (Isd), a high-poverty area where over 93% of students qualify for free or reduced lunch.
Charles Graebner Elementary faces significant academic challenges, ranking in the bottom 2% of Texas elementary schools (4555 out of 4627) for the 2025-2026 school year. Overall proficiency in English Reading (24.5%) and English Math (20.3%) is well below state averages of 54.2% and 47.0%, respectively. However, a standout strength is its bilingual math program: students taking the STAAR Math test in Spanish achieve a 44.3% proficiency rate, far exceeding the state average for Spanish tests (26.3%) and more than double the school's English Math rate. This pattern is consistent across all grades, with 3rd graders in Spanish Math scoring 52.78% proficient compared to just 15.25% in English Math. Reading remains a critical weakness in both languages, and 5th-grade Science proficiency was 0% in 2024-2025.
Despite spending $11,047 per student—a relatively high amount—academic outcomes have not matched state averages, indicating that financial resources alone cannot overcome the challenges of high poverty and language barriers. The school has shown a slight upward trend, improving from the 1st to the 2nd percentile in state ranking. For parents, the key takeaway is that Charles Graebner Elementary effectively leverages native language instruction for math, but overall literacy and science skills need significant improvement. The school's bilingual math success offers a replicable model that could be expanded to boost reading outcomes.
