Summary:
Lyons, Colorado, is served by two public schools — Lyons Elementary School (grades PK–5) and Lyons Middle/Senior High School (grades 6–12) — both part of the St. Vrain Valley School District No. Re1J, with no standalone middle school in the area. Together, these small schools educate roughly 600 students and form a high-performing system that ranks well above state averages. The district itself is ranked 23rd out of 115 Colorado districts, placing it in the top 20% statewide.
Lyons Elementary School is the clear standout, ranked #20 out of 943 elementary schools in Colorado (98th percentile, 5 stars). With 85.6% of students proficient in English Language Arts and 74.1% proficient in math — roughly 37–41 points above state averages — it is one of the top elementary schools in the state. Lyons Middle/Senior High School is also strong, ranking #40 out of 338 high schools (88th percentile) with a 4-star rating. While its math proficiency dips to 51.3% at the CMAS level, its reading and writing results are elite: 93% of 10th graders scored proficient on PSAT10 Reading, and 11th graders hit 74% on SAT Reading & Writing versus 60% statewide.
The high school also excels at keeping students on track, with a 97.6% graduation rate and a 0% dropout rate. Chronic absenteeism, however, affects roughly 1 in 5 students (18.4% at the elementary, 22.4% at the MS/HS), though that's still below the state rate of 28.4%. Math is the area to watch: while CMAS math proficiency at the secondary level (51.3%) is well above the state average (37.3%), it drops noticeably from the elementary school's 74.1%. Even so, Lyons 11th graders are twice as likely to be proficient in SAT math as the average Colorado student. With low-to-moderate economic disadvantage (20–26% free/reduced lunch) and consistently high rankings, both schools offer families an excellent education.
