Brighton High has the strongest all-around profile. It serves 2,435 students in grades 8–12 within Canyons District and ranked 15th of 139 Utah high schools in 2025–26.

AMES serves 460 students and ranked 22nd statewide, with the strongest mathematics results and the highest ninth-grade science proficiency.

Cottonwood High, part of Granite District, serves 1,451 students and needs the most improvement: it ranked 131st, had 79.0% graduation, 19.4% dropout, and 43.4% chronic absenteeism. Its proficiency averaged only 18.5%, below the state in every tested category. Attendance and student engagement appear to be especially important priorities there.
