SOUTH TEXAS ISD HEALTH PROFESSIONS vs SOUTH TEXAS ISD SCIENCE ACADEMY

South Texas ISD Science Academy and South Texas ISD Health Professions are among the top high schools in Texas, ranking #17 and #18 respectively out of 8,547 schools statewide — a gap of just one position separating two schools located 0.1 miles apart in Mercedes. Both carry an overall rating of 9.6/10, making this one of the most competitive same-city comparisons in the state. Families choosing between them are not trading quality for quality; they are choosing a professional track.

Academically, Science Academy holds a narrow edge: a 9.9/10 academic score versus Health Professions' 9.8/10, and a growth score of 9.8/10 versus 9.7/10. These are slim margins — one-tenth of a point on each metric — but they confirm that Science Academy leads on both measured dimensions. Neither school shows a meaningful weakness; the difference reflects marginal performance variation within an elite cohort rather than a structural gap in instruction.

The demographic picture diverges more sharply. Health Professions enrolls 66% of students on free or reduced-price lunch, compared to 50% at Science Academy — a 16-percentage-point gap that signals Health Professions serves a higher share of economically disadvantaged families. Science Academy is slightly larger at 846 students versus 797 at Health Professions. The student-teacher ratio at Health Professions is 14.5:1 versus 15.4:1 at Science Academy, giving Health Professions modestly smaller average class sizes despite the lower enrollment.

Both schools serve grades 9 through 12 under the South Texas ISD umbrella, which means the primary differentiator is the career pathway, not the grade structure or academic calendar. Science Academy is oriented toward STEM disciplines, while Health Professions centers its curriculum on healthcare and medical careers. A student's intended field of study is the clearest deciding factor here — the schools are otherwise near-identical on every quantitative measure available.
