Steps to get your CNA certification
Complete a state-approved 160-hour CNA training program
California requires 160 hours per HSC §1276.5 (60 classroom + 100 supervised clinical) — exceeds federal 75-hour minimum. Programs run at community colleges, ROP, vocational schools, and some long-term care facilities (free if hired). Typical cost: $600-$2,000.
Submit Live Scan fingerprinting + criminal background check
CDPH requires DOJ + FBI background check via Live Scan ($49 + site fee, typically $69-$124 total). Certain felony convictions disqualify; some can be appealed via exemption request to CDPH.
Pass the D&S Diversified knowledge exam (75%)
60-70 multiple-choice questions covering 8 topics. 75% to pass. Available in English and Spanish. PrepPass offers 200 free practice questions in 4 languages (English, 中文, Español, Tiếng Việt).
Pass the 5-skill demonstration
Performed in front of a state-approved evaluator. Skills are randomly selected from the 24 mandatory CNA skills (handwashing, vital signs, transfers, peri care, etc.). One re-test allowed if you fail.
Apply to CDPH for certification (free if you pass)
After passing both exam components, your training program submits results to CDPH. You get your CNA number and can verify status on the CDPH Nurse Aide Registry. Active certification = legally able to work.
Renew every 2 years with 24 hours of continuing education
HSC §1337.3 requires 24 hours of in-service continuing education every 2 years. Employer typically tracks this. Stay current to keep your certification active.
