There are roughly 700 high schools in Colorado, with one recent dataset listing 691 high schools statewide as of June 2025.

Quick Scoop

  • A commercial education dataset that tracks school “points of interest” lists 691 high schools in Colorado and notes the data was last updated in June 2025.
  • These include a mix of public, charter, online, and private high schools, all counted as “high school” locations in the dataset.
  • Because this is based on business/listing data rather than an official state school-count table, the exact number can shift slightly year to year as new schools open, close, or merge.

What “how many” really means

When people ask “how many high schools in Colorado,” the answer can vary depending on whether you:

  1. Count only traditional public high schools (district-run).
  2. Include public charter and online high schools.
  3. Add private and parochial high schools.

The ~691 figure comes from a directory that attempts to include all types of high school locations in the state, not just district public schools.

Why the number changes

  • School openings/closures: Each year, some schools close or consolidate, and new charters or online schools appear.
  • Classification differences: One source may split campuses, alternative programs, or online hubs into multiple “schools,” while another may treat them as one.
  • Update cycles: This dataset is specifically marked as updated mid‑2025, so it’s close to current but not “to the day.”

Simple takeaway

If you want a ballpark figure for today, “about 700 high schools” in Colorado is a reasonable, up‑to‑date approximation , with one major data source pinning it at 691 as of mid‑2025.

TL;DR: Colorado has about 700 high schools in total, with a recent detailed dataset counting 691 as of June 2025.
