Summary:

Zip code 80109 contains a single middle school: Castle Rock Middle School, which serves grades 7–8 and enrolls 660 students in Castle Rock, Colorado. The school is part of the Douglas County School District No. Re 1, a top-ranked district that sits in the 95th percentile statewide. The area is served by one of Colorado's strongest school systems, and Castle Rock Middle School benefits from that infrastructure, but its own performance tells a more nuanced story.

Castle Rock Middle School outperforms the state average in English Language Arts and Math. In the 2025–2026 school year, 49.7% of students were proficient in ELA, compared with 44.7% statewide, and 41.4% were proficient in Math, versus 37.3% statewide. However, the school trails its district by wide margins: the district posted 63.8% proficiency in ELA and 57.2% in Math. Eighth-grade Science is a bigger concern — proficiency fell from 45.6% to 35.4% in a single year, putting the school exactly at the state average while the district held steady around 54%. Seventh graders (53.7% ELA proficiency) outperformed 8th graders (46.2%) by more than seven points, suggesting a possible area for literacy support. The school's chronic absenteeism rate of 16.6% matches the district and is well below the state's 28.4%, a true bright spot. About 26% of students qualify for free or reduced lunch, and the student-to-teacher ratio is a reasonable 15.1 to 1.

The school's state ranking has slipped gradually, from 142nd (71st percentile, 4 stars) in 2023–2024 to 164th (65th percentile, 3 stars) in 2025–2026. While Castle Rock Middle School remains above the state median and posts strong attendance, it is the lowest-performing school in an elite district. Parents should watch the declining Science scores and the persistent proficiency gap between the school and its district peers. Still, with zero reported dropout rate, above-state-average core academics, and a strong attendance record, the school remains a solid option within a highly rated district.
