Summary:
Zip code 81639, located in Hayden, Colorado, is served by exactly one high school, Hayden High School, which serves grades 9–12 with a small enrollment of 119 students and a student-teacher ratio of 14.9:1. The school is part of the Hayden School District No. Re 1, which ranks in the 46th percentile among Colorado districts.
Hayden High School posts strong graduation and dropout numbers. Its graduation rate of 90.9% exceeds the state average of 85.6%, while its dropout rate of 0.7% is less than half the state’s 1.6%. The school’s state ranking has also improved notably, jumping from the 29th percentile in 2024–2025 to the 46th percentile in 2025–2026, with its star rating rising back to 2 stars. However, chronic absenteeism is a serious concern: 33.6% of students are chronically absent, which is 5.2 percentage points above the state rate of 28.4% and 12.2 points above the district rate. This disconnect between strong graduation outcomes and high absenteeism is worth attention.
Academically, math is a consistent weakness across nearly every grade and exam. Math PSAT10 proficiency was 27% versus 39% statewide, and math SAT proficiency was 18% versus 32% statewide, leaving gaps of 8 to 18 percentage points. Reading and writing results are mixed but improving, with the 11th-grade SAT rate climbing dramatically from 36% in 2024–2025 to 65% in 2025–2026, now above the state’s 60%. Science proficiency improved from 16.1% to 23.1%, though it remains just below the state’s 24.8%. Because the school is small, each percentage point represents roughly one student, so year-to-year swings like the reading and writing jump can be driven by a very small number of students and should be interpreted with caution.
