Summary

Cast Technical High School is a public high school in downtown San Antonio, TX, serving 451 students in grades 9-12 as part of the San Antonio Independent School District (Isd). Despite the district ranking in the bottom 20% statewide, Cast Tech stands out as a high-performing school with a 4-star rating and a near-perfect graduation rate of 99.1%.

What truly sets Cast Tech apart is its exceptional performance in key subjects and its ability to support all students. The school excels in Biology (87.2% proficiency) and English II Reading (77.5%), far exceeding state averages. This is a stark contrast to nearby schools like Healy-Murphy and Cooper Academy At Navarro, which have proficiency rates in the single digits for core subjects. Even compared to its co-located neighbor, Fox Technical High School, Cast Tech outperforms by significant margins—for example, 17.5 percentage points higher in Biology. The school also demonstrates strong equitable success, ranking in the 84th percentile for students from low socio-economic backgrounds and the 90th percentile for special education students. However, a recent drop in support for English Language Learners (from the 84th to 46th percentile) is a potential concern to watch.

While Cast Tech shines in science and English, Algebra I remains a relative weakness, with scores below the state average. Still, the school’s consistent year-over-year improvement—climbing from a 3-star to a 4-star rating—shows a commitment to growth. For parents in the San Antonio area seeking a high-quality education within a challenging district, Cast Technical High School is a standout option that combines strong academics with a supportive culture, making it a true beacon for student success.
