Brentwood SHS vs Upper Saint Clair HS

Upper Saint Clair HS holds a commanding lead in overall performance, rating 9.7/10 against Brentwood SHS's 8.3/10 — a 1.4-point gap that translates to a dramatic difference in state standing. Upper Saint Clair HS ranks #6 of 2,842 Pennsylvania schools, placing it in the top fraction of a percent statewide. Brentwood SHS ranks #344 of 2,842, which is still a strong showing in the top 15 percent, but the two schools are not in the same competitive tier by any conventional measure.

The academic gap drives most of that difference. Upper Saint Clair HS scores 9.8/10 on academics versus Brentwood SHS's 7.6/10 — a 2.2-point delta that reflects measurably higher proficiency rates on state assessments. Growth tells a different story: Brentwood SHS scores 9.9/10 on student growth, actually edging Upper Saint Clair HS's 9.5/10. That means students at Brentwood are gaining academic ground at a slightly faster rate relative to their starting points, even if their absolute proficiency levels sit lower. Families weighing trajectory against baseline performance will find that distinction meaningful.

The two schools serve very different student populations across 5.8 miles of Pittsburgh. Brentwood SHS enrolls 345 students with 58% qualifying for free or reduced-price lunch; Upper Saint Clair HS enrolls 1,301 students with only 14% on free or reduced lunch. The smaller enrollment at Brentwood produces a tighter student-teacher ratio of 12.3:1 compared to Upper Saint Clair HS's 13.7:1, meaning Brentwood students have marginally more classroom access per teacher despite the school's lower academic scores. Upper Saint Clair's scale supports a broader course catalog, extracurricular depth, and varsity sports rosters that a school of 345 cannot replicate.

Both schools serve grades 9–12 exclusively, so the comparison is apples-to-apples at the high school level. Upper Saint Clair HS's elite state ranking signals consistent performance on college-preparatory benchmarks. Brentwood SHS's near-perfect growth score signals a faculty that outperforms expectations given its demographic mix — 58% free/reduced lunch is a proxy for resource constraints, and a 9.9 growth score in that context represents a genuine instructional achievement.
