Summary:

Zip code 78240 in San Antonio, Texas, is home to 10 schools serving approximately 9,773 students, including 7 elementary schools, 1 middle school, 1 high school, and 1 alternative school, primarily under the Northside Independent School District (Isd) alongside smaller charter networks.

The standout performer is Basis San Antonio Pri- Medical Center Campus, ranked in the 98th percentile statewide with test scores 30-40 points above state averages, despite having the lowest per-student spending ($7,350) and highest student-teacher ratio (19.7:1). Great Hearts Forest Heights also excels as a strong alternative school, ranking in the 77th percentile with high school EOC exam proficiency rates well above state averages. In contrast, McDermott Elementary is the most challenged, ranking in the 2nd percentile with critically low test scores (e.g., 5th-grade math at 16.19%), while Rudder Middle shows a three-year declining trend and alarmingly low 7th-grade math proficiency (8.67%). Marshall High School is a solid, average performer with a 94.5% graduation rate but struggles with Algebra I proficiency (28.97%).

A key takeaway is the stark performance gap driven by economic disparity: charter schools like Basis and Great Hearts serve far fewer students from low-income backgrounds (average ~9.8% free/reduced lunch) compared to Northside ISD schools (average 69.5%). Spending does not correlate with success, as the highest-spending schools like Leon Valley Elementary ($11,809) and Oak Hills Terrace Elementary ($11,351) are among the lowest-performing, while Basis spends the least. Additionally, Somerset Academy Oaks is a hidden gem—a small charter with a 3-star rating and strong 3rd-grade reading (75%) and math (62.5%) scores, outperforming many local Northside ISD schools.
