Summary:
The six schools in San Antonio's 78252 zip code serve a predominantly elementary-aged population across two districts, Southwest Independent School District (Isd) and Medina Valley Independent School District (Isd), with a high average economic disadvantage rate of 69.4%.
Cast Stem High School stands out as the top performer, boasting a 100% graduation rate, a 0% dropout rate, and a 4-star rating, likely due to its small size (173 students), low student-teacher ratio (10.2:1), and higher per-pupil spending ($13,798). In contrast, the much larger Southwest High School (2,363 students) has a 95.5% graduation rate but struggles with math, where Algebra I proficiency (23.04%) is less than half of English II Reading proficiency (57.45%). Among elementary schools, Southwest Elementary excels with a standout bilingual program, achieving 83.33% proficiency in 5th Grade Spanish Reading versus 34.82% statewide, while Medio Creek Elementary faces severe challenges with the highest poverty rate (87.57%) and lowest scores, including just 8.57% in 5th Grade Science. The two Medina Valley ISD schools, Silos Elementary and Luckey Ranch Elementary, generally perform closer to state averages, though Silos has the highest student-teacher ratio (19.4:1).
A key takeaway is that reading proficiency consistently outpaces math across all schools, indicating a systemic weakness in math instruction. The data also reveals a "small school advantage" at Cast Stem, where personalized resources overcome poverty challenges, while Medio Creek's declining 1-star rating signals a need for urgent intervention. Overall, Southwest ISD offers pockets of innovation like Cast Stem and Southwest Elementary's bilingual program, but families should weigh these against the district's broader struggles, particularly in math and at high-poverty schools.
