Thornton Fractional Township HSD 215

Thornton Fractional Township HSD 215 includes two public high schools serving grades 9–12. Across the latest reported tests, both schools scored below state proficiency levels in every subject and grade, with the largest average shortfall in math: 16% proficient across the schools versus 40% statewide, a 23-point gap. The clearest area-wide concern is that neither school meets state proficiency in any of the nine comparisons.

Thornton Fractnl So High School stands out, leading in seven of nine comparisons; its largest advantages over Thornton Fractnl No High School are 9 points in grade 9 ELA and 8 points in grade 10 science. South’s strongest result is 52% proficiency in grade 9 ELA, still 9 points below the state. North has two narrow leads—1 point in grade 11 ELA and 3 points in grade 9 math—but has the lowest score in five comparisons; its grade 10 math result is 9%, 27 points below the state. Graduation rates are stronger than test scores suggest: South is at 93% and North at 91%, both above the state’s 90%.

Results declined overall from 2024–2025 to 2025–2026: the schools’ average fell from 29% to 27%, while their average gap from the state widened from 19 to 21 points. The subject pattern differed: ELA fell 4 points on average, science fell 3, and math rose 2. SchoolDigger ranks South 502 of 620 (19th percentile) and North 532 of 620 (14th percentile). Their student-teacher ratios are similar—16.9 at South and 16.5 at North.
