Summary

Horizon High School is a large comprehensive high school in Brighton, Colorado, serving 1,966 students in grades 9–12 as part of the Adams 12 Five Star Schools district. For the 2025–2026 school year, Horizon ranks 95th out of 338 Colorado high schools, placing it in the 72nd percentile statewide with a 4-star rating — a position it has held fairly consistently over the past decade.

Academically, Horizon outperforms its own district and the state in nearly every subject and grade level. On the 11th-grade SAT, 66% of students were proficient in reading/writing and 42% in math, compared to district rates of 55% and 33% respectively. Science is a particular strength: 36.1% of 11th graders scored proficient on the CMAS science test, well above the state rate of 24.8% and even slightly ahead of Legacy High School. Among nearby traditional high schools, only Legacy clearly outperforms Horizon — Mountain Range High School, Northglenn High School, and Thornton High School all trail by wide margins. Horizon also boasts the highest graduation rate in the area at 96.8%, with a dropout rate of just 0.7%.

Horizon also posts strong outcomes for student groups that are often underserved. Hispanic students rank in the 78th percentile statewide, and low-income students in the 70th percentile — both earning 4-star ratings. The school's free/reduced lunch rate is 33.1%, notably lower than most surrounding schools. However, there are areas of concern. Students with disabilities rank in the 5th percentile statewide, a sharp decline from previous years, and chronic absenteeism rose to 32.2% in 2024–2025. Math proficiency, while above state averages, remains noticeably lower than reading. Overall, Horizon is a strong, stable option for families seeking a large school with solid academics and high graduation rates.
