How to get licensed
- 1
Meet the prerequisites
Pass a criminal background check. No Colorado-published minimum age was found for nurse aide training/certification, so left null rather than guessed. A criminal background check is required: Colorado Board of Nursing applicants (including nurse aides, under the Nurse and Nurse Aide Practice Act, Title 12, Article 255, C.R.S.) must submit fingerprints for a Colorado Bureau of Investigation and FBI criminal history check per C.R.S. §24-60-380(III)(c)(6).

Complete approved training
Complete 75 hours of training (including 16 clinical hours) at a state-approved program. At least 75 hours of instruction at a Board-approved nurse aide training program meeting federal OBRA '87 standards, including a minimum of 16 hours of pre-clinical classroom instruction (communication, infection control, safety, resident independence/rights) and a minimum of 16 hours of clinical instruction under direct RN/LPN supervision. Matches the federal 42 CFR 483.152 floor of 75 hours (Colorado does not require additional hours beyond the federal minimum). [1]

Written (or Oral) Examination
Pass the Written (or Oral) Examination (fee: $50). 70 multiple-choice questions, written in English; an Oral Examination (English or Spanish, 60 multiple-choice + 10 reading-comprehension items via audio overlay) is available at the same $50 fee. [2]

Skills Evaluation
Pass the Skills Evaluation (fee: $85). Hands-on demonstration of 5 randomly selected nurse aide skills, 30 minutes allowed. Both the Written/Oral and Skills components must be passed within 24 months of Credentia receiving the application to be listed on the Colorado Nurse Aide Registry. [2]

The Board's own CNA registry application/certification/renewal fee amounts could not be confirmed from a primary DORA source within research time available — secondary sources disagree (some describe the initial application as fee-free beyond the Credentia exam costs, others cite a $50 application fee and a $25 renewal fee), and the Board of Nursing's fee rule (3 CCR 716-1) was not locatable as a directly fetchable primary document. Left null rather than guessing which figure is current; only the confirmed Credentia exam fees are listed.
Renewal & continuing education
Renew every 2 years.
All Colorado CNA certificates expire on January 31 of odd-numbered years (a fixed biennial cycle, not an individual anniversary date), with a 60-day grace period. No continuing-education hours are required; instead, renewal requires the CNA to attest that they received monetary compensation for at least 8 hours of nursing care activities during the 24 months prior to the renewal/reinstatement application.
Reciprocity
Endorsement/reciprocity from another state is available.
No interstate compact covers CNAs/nurse aides. Colorado offers Certified Nurse Aide - Certification by Endorsement (applied for online through DORA's Online Services) for candidates holding a current, valid nurse aide certificate from a jurisdiction with a substantially similar scope of practice.
