Summary

DC Montessori Charter School is a PK-8 charter school in Castle Rock, CO, serving 547 students as part of Douglas County School District Re 1. Among 10 nearby comparison schools, it ranks the lowest statewide, sitting at the 60th percentile in 2025-2026. Nearby schools like Gold Rush Elementary and Redstone Elementary consistently rank in the 98th percentile, while Meadow View Elementary sits at the 70th. This isn't a one-year dip—DC Montessori has hovered between the 52nd and 69th percentile for a decade.

The biggest concern for parents is math. Only 40.2% of DC Montessori students scored proficient or advanced on CMAS Math in 2025-2026, versus 57.2% for the district and 37.3% for the state. That's the lowest math proficiency of any nearby school—Gold Rush Elementary reaches 80.9% and even Meadow View Elementary posts 50.4%. The gap shows up at every elementary grade level: 3rd through 6th grade math proficiency runs 11 to 24 points below district averages. ELA is somewhat closer to par at 57.6% versus the district's 63.8%, but it's still second-lowest among neighbors. The most telling comparison is American Academy, another PK-8 charter just 0.72 miles away. It beats DC Montessori in ELA (71.5% vs 57.6%) and math (65.3% vs 40.2%) while also posting a far lower chronic absenteeism rate.

Operational metrics are worth watching, too. At 16.1%, DC Montessori's chronic absenteeism rate is the highest among nearby schools—Timber Trail Elementary sits at just 5.8%—and its 19.1 student-teacher ratio is the area's highest. There are genuine bright spots: 8th grade science proficiency reached 81.3% in 2024-2025 versus 53.9% districtwide, and 6th grade ELA hit 69.4%, above the district average. Because only 9.7% of students qualify for free or reduced lunch, the math struggles aren't easily explained by poverty. Families considering this Montessori program should weigh its distinctive instructional approach against these results, especially at the elementary level.
