Summary:
The five public schools in Austin's 78703 zip code, all part of the Austin Independent School District (Isd), serve 4,311 students across elementary, middle, and high school levels, and are characterized by strong reading proficiency and a notable "two-tiered" math system.
Casis Elementary stands out as the academic powerhouse, earning a 5-star rating and ranking in the 92nd percentile statewide, with test scores 20-30 points above the district average. Austin High School is a consistent high performer, earning a 4-star rating and exceeding state averages in every subject, particularly Biology (88.27% proficient) and U.S. History (87.88%). O Henry Middle presents a math paradox: while its standard 6th-8th grade math scores lag behind state averages (e.g., only 10.28% proficient in 7th grade math), its Algebra I End-of-Course exam proficiency rate is an astronomical 98.08%, likely driven by accelerated students from Casis. Mathews Elementary and Bryker Woods Elementary both hold 4-star ratings, though Bryker Woods has seen a slight decline from a 5-star rating in recent years.
Key metrics reveal significant variation in socioeconomic diversity, with free/reduced lunch eligibility ranging from 8.74% at Casis to 34.7% at Mathews. Spending per student varies from $9,725 at Austin High to $11,852 at Casis, while student-teacher ratios are lower at elementary schools (14.2-15.1:1) compared to the high school (18.4:1). A universal strength across all schools is reading proficiency, with every school outperforming district and state averages. However, mathematics is a weakness at the middle and high school levels, with Austin High underperforming in Algebra I (38.53% proficient vs. 54.03% statewide), despite excelling in all other subjects. This creates a clear takeaway: families can expect excellent literacy instruction throughout the feeder pattern, but should investigate math placement and acceleration options carefully, especially at O. Henry Middle and Austin High.
