Summary:
Zip code 80605 in Brighton, Colorado is home to just one school: Glacier Peak Elementary School, a public K-5 elementary school serving 412 students in the Adams 12 Five Star Schools district. With no middle or high schools in the area, Glacier Peak serves as the entry point for local students, who must leave the zip code for secondary education.
Academically, Glacier Peak shows a clear split between English Language Arts and STEM subjects. Schoolwide ELA proficiency reached 42.3% in 2025-2026, nearly matching district and state averages, and improved by 9.1 points year over year. Math tells a different story: just 26.5% of students are proficient, a 10.8-point gap versus the state. The concern is sharpest in 5th grade, where only 15.4% of students are proficient in math and 14.1% in science, compared to state averages around 39% and 36%, respectively. Fifth grade ELA also lags at 41.3% versus the state's 49.9%. On a positive note, chronic absenteeism is a bright spot: 22.2% of students are chronically absent, well below the district rate of 32.2% and the state rate of 28.4%.
Glacier Peak has earned a 2-star rating from the state for three consecutive years, with its percentile ranking slipping from the 43rd percentile in 2023-2024 to the 36th percentile in 2025-2026. This places the school below its own district, which ranks in the 57th percentile of Colorado districts — a mismatch that makes Glacier Peak a candidate for additional district support. Nearly half of the student body (47.57%) qualifies for free or reduced lunch, and the student-teacher ratio is 16.8 to 1. The school's biggest opportunity lies in translating its ELA progress and strong attendance into targeted math and science intervention, particularly for upper elementary students.
