Summary:

Castle Rock, Colorado is served by 21 schools within the Douglas County School District No. Re 1 — one of Colorado's highest-rated districts at #6 out of 115 statewide — including 15 elementary schools, 2 middle schools, and 4 high schools enrolling approximately 13,739 students. Castle Rock schools consistently outperform state averages in English Language Arts and math, though they trail district averages in mathematics and science.

At the elementary level, Timber Trail Elementary School is the clear standout, ranked #33 of 943 Colorado elementary schools (97th percentile) with 78.4% ELA and 74.9% math proficiency, plus the lowest chronic absenteeism in the city at 5.8%. Buffalo Ridge Elementary School is a rising star, climbing from the 90th to 95th percentile over three years, while Academy Charter School delivers exceptional middle-grade results, including 88.6% ELA proficiency in 8th grade. Among high schools, Renaissance Secondary School leads the city, ranked #38 of 338 high schools (89th percentile) with a 97.2% graduation rate and SAT math proficiency (56%) well above district averages. Castle View High School, the largest school with 1,938 students, posts a strong 96.3% graduation rate but trails the district in SAT math (39% vs. 44%).

However, significant challenges remain. Middle-school math is a citywide concern — Mesa Middle School shows just 35.4% math proficiency and Castle Rock Middle School 41.4%, well below the district's 57.2%. Chronic absenteeism exceeds 20% at Douglas County High School, Mesa Middle, Castle Rock Elementary School, South Ridge Elementary, and Renaissance Secondary. Equity gaps are notable, with South Ridge Elementary carrying a 53.1% free/reduced lunch rate and the city's lowest test scores, while Daniel C. Oakes High School — an alternative school with a 41.7% graduation rate — serves a fundamentally different population and should not be compared to comprehensive high schools. Families weighing school options should factor in these patterns alongside the district's many strengths.
