Summary

Denison Montessori School is a public Montessori elementary school in southwest Denver serving 364 students in grades PK through 6 as part of School District No. 1, a district ranked in the 38th percentile statewide. The school ranks 544th out of 943 Colorado elementary schools (42nd percentile, 2 stars), placing it near the middle of the state distribution. Denison has improved steadily, rising from the 27th percentile in 2023-2024 to the 42nd percentile in 2025-2026. Its Montessori model and extended PK-6 grade span set it apart from most neighboring schools, which typically end at 5th grade.

Denison's clearest strengths are literacy and attendance. English Language Arts proficiency reached 43.0% in 2025-2026, nearly matching district (42.5%) and state (44.7%) averages, while surpassing most nearby schools — only Sabin World School (50.9%) and Doull Elementary School (47.4%) scored higher among immediate neighbors. ELA scores have climbed steadily from 34.9% in 2022-2023. Chronic absenteeism stands at 29.1%, nearly identical to the state rate of 28.4% and far better than the district's 38.1% — a bright spot in a neighborhood where rates at nearby schools range from 31.4% to 53.9%. Hispanic students at Denison have also shown dramatic improvement, moving from the 12th percentile statewide in 2023-2024 to the 78th percentile in 2025-2026.

Math and science remain areas of concern. Math proficiency is 29.6% versus 37.3% statewide, and 5th-grade science is 21.2% against a 36.1% state average. Denison's student-teacher ratio of 17.6 is the highest among nearby schools and has been rising. In the southwest Denver cluster, Denison is a solid option: Sabin World School stands out above it in both subjects, and Gust Elementary School is a close peer, but Denison outperforms Traylor Academy, Force Elementary School, Rocky Mountain Prep Southwest, Charles M. Schenck (CMS) Community School, Johnson Elementary School, and Castro Elementary School. Notably, Denison also outperforms Lasley Elementary School even though Lasley belongs to the higher-ranked Jefferson County School District No. R-1 — a reminder that what happens inside a school can matter more than its district's reputation.
