Summary:

The 14 schools in zip code 78570 (Mercedes, TX) serve students from Pre-K through 12th grade, primarily under the Mercedes Independent School District (Isd) and the South Texas Independent School District (Isd), in a community where over 80% of students face significant economic challenges.

The standout schools in this area are the magnet campuses of the South Texas Independent School District (Isd), which consistently outperform all others. South Texas Independent School District (Isd) Science Academy leads with a 5-star rating, a 100% graduation rate, and test scores 30-40 points above the state average. South Texas Independent School District (Isd) Health Professions is a close second with similar results. Within the Mercedes Independent School District (Isd), Mercedes Early College Academy is a bright spot, achieving a 100% graduation rate and test scores near state averages despite serving a high-poverty population. In stark contrast, Mercedes Academic Academy is the most challenged school, with a 1-star rating, a 68.7% graduation rate, and a 14.9% dropout rate, despite spending nearly $16,000 per student.

A critical finding is the middle school math crisis: at Sgt Manuel Chacon Middle, only 3.27% of 7th graders were proficient in math, yet students taking advanced Algebra I achieved a 92.86% proficiency rate. This highlights a system that accelerates a few high-achievers while failing the majority. Overall, the zip code reveals a tale of two districts: the South Texas Independent School District (Isd) ranks in the 94th percentile statewide, while the Mercedes Independent School District (Isd) ranks in the 15th percentile, showing that high achievement is possible in this community but not yet the norm for most students.
