22 public K-12 schools in Castle Rock from NCES Common Core of Data: enrollment, grade span, demographics, and Civil Rights Data Collection statistics for every active campus.
National city placement
According to NCES CCD 2024-25, Castle Rock has more public-school enrollment than 87% of the 4,487 US cities in this directory. Castle Rock sits in the broad middle of the national city distribution rather than at a single obvious extreme. Its scale, average Resource Investment Index, and staffing position need to be read together: a middle placement on one measure does not cancel a stronger or weaker result on another. The percentile panel makes those dimensions explicit, and the school table shows where the city aggregate breaks into materially different campus profiles.
14 of Castle Rock's 22 listed schools use NCES's combined or “other” grade-level classification. Citywide averages therefore blend campuses serving unusually broad or nonstandard grade spans with conventional elementary, middle, and high schools. Grade configuration is a first-order comparison here, not a minor label.
The 56-point gap between Daniel C Oakes High School--Castle Rock and Early Childhood Center shows the range hidden by Castle Rock's average Resource Investment Index. The city figure is useful for national placement, but families ultimately choose among campuses with different grade spans, enrollment, district affiliations, and reported support fields. Start with schools serving the relevant grade level, then compare the index components rather than assuming the city average describes any one classroom.
Castle Rock school enrollment ranges from 110 students (lowest) to 1,938 students (highest), a spread of 1,828 students. That spread reflects typical urban portfolio variation between specialty programs and large neighbourhood schools. Per-school staffing and program breadth can differ sharply at opposite ends of that enrollment range, so the city average should not be treated as a typical campus.

Castle Rock's listed schools share one district boundary, budget authority, and reporting chain. That makes citywide and districtwide governance easier to compare, but it does not make individual campuses uniform: grade configuration, staffing, programs, and student need can still vary materially within the same school district.

student-teacher ratio is the simplest comparative metric but it does not capture the full picture: the ratio counts FTE classroom teachers against total enrollment, push-in specialists, English-language aides, special-education co-teachers, and counselors are not included in most reporting Higher values may reflect larger urban scale or recent resource constraints that have widened the gap.
23% of the city's listed public-school campuses are reported as charter schools in NCES CCD. Charter status identifies a different governance arrangement; it does not establish admissions availability, academic quality, or the share of city students enrolled in those campuses.

Data from NCES Common Core of Data (CCD) 2024-25 and Civil Rights Data Collection (CRDC) 2021-22. The Resource Investment Index uses reported student-teacher ratio, counselor access, gifted programs, and attendance; it is not an academic rating. Cities must include at least five schools to be listed. This public-data comparison is for informational purposes: verify current enrollment, attendance boundaries, and programs with the school district before acting.
