How the BOULDER Public-School Landscape Breaks Down
BOULDER, CO enrolls 13,104 students across 30 public schools reporting to the National Center for Education Statistics. Of those, 3 are charter schools, giving families genuine alternatives to the traditional neighbourhood assignment model. The average student-teacher ratio across the city is 15.9:1, Schools must report at least five campuses in a city to appear in this listing, which is why very small towns may redirect to the broader county or state view.
The highest-ranked campus in BOULDER is Boulder High School, scoring 33/100 (F) with 1,939 enrolled students at the high level. Families should treat any single ranking as a starting point rather than a verdict — a school serving fewer at-risk students or offering more AP classes will score higher on resource-based composites even if individual teachers or programs elsewhere are stronger. The quality score framework is transparent and rebuilt from raw NCES and Civil Rights Data Collection (CRDC) inputs, so each component can be inspected on the individual school pages linked in the table below.
BOULDER schools sit within multiple district boundaries, which matters for property taxes, redistricting votes, and bond measures. Each district files its own NCES F-33 financial return, meaning per-pupil spending can vary noticeably even between neighbouring campuses in the same city. Use the table to sort by enrollment, level, or district, then click any school name for campus-level demographics, Title I status, counselor and nurse staffing, AP courses, chronic-absenteeism rates, and district per-pupil spending. The sidebar links also connect BOULDER housing costs, wage data, and crime statistics — context many parents weigh alongside test-adjacent school signals when relocating.

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 Variation between sub-units within BOULDER is typically wider than the BOULDER-aggregate figure suggests.
