Best Public Schools in Dillon, CO

Dillon, Colorado is served by exactly two public elementary schools — Dillon Valley Elementary School and Summit Cove Elementary School — both part of Summit School District No. Re 1 and both serving grades PK-5. The district ranks 37th of 115 in Colorado, but the city's two schools deliver notably different results. There are no middle schools or high schools within city limits, so Dillon's entire educational profile rests on these two elementary schools.

Summit Cove is the clear academic standout. It ranks 398th of 943 Colorado elementary schools (58th percentile) with a 3-star rating, and it exceeds both district and state averages in ELA and math. Math is its signature subject: 47.3% proficiency is about 10 points above the state average. Summit Cove also has a lower poverty rate (32% free/reduced lunch) and a more favorable student-teacher ratio (11.9 to 1) than Dillon Valley, and its state ranking has climbed from the 44th to the 58th percentile over three years. Dillon Valley, by contrast, ranks 594th of 943 (37th percentile) with a 2-star rating. It trails state averages in nearly every subject and grade, has a 51% free/reduced lunch rate, larger class sizes (13.7 to 1), and its ranking has steadily slipped from the 47th to the 37th percentile. Notably, Dillon Valley's only above-state performance is 4th-grade ELA at 48.3%.

Both schools face shared challenges. Chronic absenteeism is high at both — 29.5% at Dillon Valley Elementary School and 33.3% at Summit Cove Elementary School, both above the state rate of 28.4% — yet Summit Cove still achieves far stronger scores, showing attendance is not the only factor. The most urgent concern is early literacy: 3rd-grade ELA proficiency is just 23.6% at Dillon Valley and 28.0% at Summit Cove, far below the state's 40.8%. The brightest spot is 4th grade, especially at Summit Cove, where 68.6% of students are proficient in ELA — more than 20 points above the state. Families should also know that because Dillon has no secondary schools, all students must transition to schools outside the city after 5th grade.
