Summary

Lyons Middle/Senior High School is a small school in Lyons, Colorado, serving 344 students in grades 6 through 12 as part of the St. Vrain Valley School District No. Re1J. Despite its size — one-fifth the enrollment of nearby Niwot High School, Silver Creek High School, or Boulder High School — the school consistently ranks among Colorado's top schools. In 2025–2026, it ranked 40th out of 338 high schools statewide (88th percentile), earning 4 stars every year since 2015–2016. Among nearby schools, only Niwot High School ranked higher; the school outperformed Boulder High School, Silver Creek High School, Berthoud High School, Longmont High School, and Skyline High School.

The school's test scores are well above district and state averages. In 2025–2026, 71.8% scored proficient in CMAS English Language Arts, compared to 51.0% for the district and 44.7% for the state. SAT math proficiency reached 64%, the highest among nearby schools, surpassing Niwot High School (51%), Boulder High School (56%), and Silver Creek High School (47%). PSAT 10 Reading/Writing proficiency was 93%, the best locally. The graduation rate has held between 97.6% and 100% in recent years, with a 0.0% dropout rate for three consecutive years. Chronic absenteeism, at 22.4%, is better than the district and state averages and far lower than Skyline High School (48.4%) or Longmont High School (42.1%). With a student-teacher ratio of 14.3, the school offers small class sizes and a more personalized experience than most neighboring high schools.

Literacy is the school's greatest academic strength, with ELA proficiency consistently in the high 60s to high 70s. The school also stands out for female students, who ranked in the 97th percentile statewide in 2024–2025; male students also perform well, but there is a meaningful gender gap worth understanding. The student population is changing: free/reduced lunch eligibility rose from 18.2% to 26.2% between 2023–2024 and 2024–2025, yet academic performance remained strong. Chronic absenteeism ticked upward from 16.3% to 22.4% and is worth monitoring. Overall, Lyons Middle/Senior High School is a compelling example of a small school achieving at an elite level through consistency, strong relationships, and a low-dropout culture.
