Thankfully, Colorado has a more flexible approach compared to some other states when it comes to substitute teaching. In contrast to the strict requirement of a professional teacher license, the Colorado Department of Education (CDE) provides three distinct substitute teacher authorizations, each with its own set of educational and experience prerequisites.

What Requirements Are Needed To Be a Substitute Teacher In Colorado?
To qualify for a 1-year substitute authorization to work in K-12 classrooms in Colorado, you must meet the following requirements:
- Hold a high school diploma or its equivalent.

The Three Colorado Substitute Authorizations
The Colorado Department of Education (CDE) issues three substitute teacher authorizations, so you can qualify at the level that matches your background:
- 1-Year Substitute Authorization — the entry point. Requires a high school diploma or equivalent, a fingerprint-based background check on file with CDE, and attestation of successful experience working with children. No college degree required.
- 3-Year Substitute Authorization — requires a bachelor's degree or higher from a regionally accredited college or university.
- 5-Year Substitute Authorization — for candidates who hold an active or expired full teacher license (from Colorado or another state); the longest-term option.
All three let you substitute in K-12 classrooms across Colorado; each district chooses which it accepts.
