Summary:
The 78570 zip code area is home to 15 schools across two school districts - Mercedes Independent School District (ISD) and South Texas Independent School District (ISD). The schools include 5 elementary, 2 middle, 7 high, and 1 alternative school, serving students from pre-K through 12th grade.
Two schools stand out as exceptional performers - the South Texas ISD Science Academy and the South Texas ISD Health Professions, both public magnet high schools. These schools boast 5-star ratings, high rankings, stellar test scores, and near-perfect graduation and retention rates. In contrast, the Mercedes ISD schools generally lag behind, with lower test scores, high poverty rates, and lower funding.
Across the area, graduation rates hover around 88-90%, below the state average, except for the South Texas ISD magnet schools which achieve exceptional 99.7% rates. Test scores on the STAAR exams vary widely, with the magnet schools significantly outperforming their peers. Socioeconomic factors also play a role, as the Mercedes ISD schools serve student populations with 88-100% qualifying for free/reduced lunch, compared to 50-66% at the magnet schools. This complex landscape highlights the need for targeted, specialized programs to boost student outcomes, even in disadvantaged communities.
