Summary:
ZIP code 81057 covers Mc Clave, Colorado, and contains just 2 schools serving roughly 231 students: McClave Elementary School (grades PK-6, 126 students) and McClave Undivided High School (grades 7-12, 105 students). Both belong to McClave School District No. Re-2, a 5-star district ranked 7th out of 115 in Colorado — the 94th percentile statewide.
The standout secondary school is McClave Undivided High School, ranked 28th out of 338 Colorado high schools (92nd percentile) for 2025-2026, up from 63rd just two years earlier. Its math results are extraordinary: 89.5% proficiency in 8th grade math, 88% on PSAT10 Math, and 74% on SAT Math — roughly double the state averages. It also posted a 100% graduation rate and 0% dropout rate. McClave Elementary School is not far behind, ranked 261st out of 943 elementary schools (72nd percentile, 4 stars). The elementary school shines in 5th grade science (73.7% vs. 39.0% statewide) and 6th grade ELA and math (68.8% in both), though its rank slipped from the 87th percentile in 2024-2025.
The biggest concern is attendance: chronic absenteeism at McClave Undivided High School is 39.0%, well above the 28.4% state rate, while McClave Elementary School is just 5.5% — despite being on the same campus. Science results are inconsistent at the secondary level; 11th grade science is excellent (63.2% vs. 24.8% statewide) but 8th grade science falls slightly below state average, likely due to small cohort sizes. Elementary students show strong growth, improving from 42.9% proficiency in 3rd grade to 68.8% by 6th grade. With tiny class sizes (about 11.5 to 1), a top-7 district, and strong math achievement across all grades, these schools offer a high-quality education for a small rural community.
