Aspen School District No. 1

Aspen School District No. 1 serves 1,557 students across four schools in the mountain community of Aspen, Colorado, covering grades PK-12 with a mix of elementary, middle, high, and charter schools. Overall, this is an elite Colorado district—ranked 4th out of 115 districts with a 5-star rating—and every school in the Aspen School District No. 1 exceeds state proficiency averages in both English language arts and math. The standout performer is Aspen Community Charter School, a small 135-student school that posts the district’s highest test scores (69% ELA, 64.4% math) and has climbed from the 59th to the 88th state percentile in just two years. Aspen High School is also notable for its 97.9% graduation rate and strong SAT reading scores, though nearly half of its students are chronically absent.

Comparing schools directly, Aspen Elementary School showed the most improvement, with math proficiency jumping from 44.2% to 55.6% in one year—now the only school in the district where math exceeds reading. Aspen Middle School lags behind the others academically, though it still beats state averages (49.1% ELA, 43.9% math), and it has no recent state rank history. The charter school’s low student-teacher ratio of 10.4 may contribute to its success, while the three traditional schools share a single campus on High School Road, potentially easing transitions between grades.

The biggest district-wide concern is chronic absenteeism, which rises sharply with grade level: 24.2% at the elementary, 26.5% at the charter, 37.8% at the middle school, and 47.7% at the high school—well above the state’s 28.4% average. This is surprising given the district’s high test scores and near-perfect graduation rate. Another pattern is that reading proficiency consistently outpaces math, especially at the high school level, where 86% of 11th graders are proficient in SAT reading but only 48% are proficient in SAT math. Free/reduced lunch data is missing for all schools, so the full equity picture remains unclear, but the available data shows Aspen students are strong readers with an evident need to focus on secondary mathematics and attendance.
