Summary:

ZIP code 80104 in Castle Rock, Colorado is home to 10 schools serving grades PK-12, all within the highly rated Douglas County School District No. Re 1 — one of Colorado's top districts, ranked 6th of 115 statewide. The mix includes six elementary schools, one middle school, and three high schools, serving roughly 5,973 students. Enrollment ranges from just 113 students at Daniel C Oakes High School--Castle Rock to 1,659 at Douglas County High School.

Families will find several standouts. Flagstone Elementary School is the top-rated elementary school, ranking in the 88th percentile with 66% ELA and 65% math proficiency, and it has improved steadily over three years. The highest-rated high school is Renaissance Secondary School, ranked in the 89th percentile with a 97.2% graduation rate and 82% SAT reading/writing proficiency. Renaissance Expedition Learn Outward Bound School posts the lowest chronic absenteeism (12.7%) and lowest poverty rate (6.09% free/reduced lunch). At the other end of the spectrum, South Ridge Elementary An IB World School has the highest poverty rate (53.1%) and the lowest elementary test scores, while Daniel C Oakes High School--Castle Rock appears to serve an alternative/credit-recovery population, with a 41.7% graduation rate and no reported test scores.

Several patterns matter for parents. Poverty and achievement are closely linked in this ZIP code: the highest-poverty schools tend to rank lowest, while the lowest-poverty schools perform well above state averages. Math is the consistent weak spot — Douglas County High School posts 66% SAT reading proficiency but just 31% in math, a gap seen at nearly every school. Chronic absenteeism is also a hidden challenge, averaging about 20.8% across these schools, above the district's 16.6% average. Notably, the schools with the best attendance — Renaissance Expedition and Flagstone — are also among the highest performers. The bottom line: families should evaluate schools individually, because outcomes vary dramatically even within a few square miles of this otherwise strong district.
