1.1 California CNA Certification and Requirements

Who Certifies California CNAs

In California, the California Department of Public Health (CDPH) is the state agency that certifies nurse assistants and maintains the California Nurse Assistant Registry. You are not legally a CNA until CDPH places your name on that registry. The competency exam itself is administered by a separate testing vendor, D&S Diversified Technologies / Headmaster, through the California TMU scheduling system.

Understanding this split is the first exam-relevant fact: CDPH controls eligibility, application processing, training-program approval, registry placement, renewal, and misconduct review, while D&S Headmaster controls scheduling, test events, the knowledge test, and skills scoring.

This division matters in practice. A candidate can pass both exam parts and still not be a certified CNA if CDPH never received a complete application or a clean Live Scan result. Always treat the CDPH paperwork as seriously as the test itself.

The 160-Hour Training Requirement

California requires more training than the federal floor. The Omnibus Budget Reconciliation Act of 1987 (OBRA '87) sets a national minimum of 75 hours, but California requires 160 total hours in a CDPH-approved Nurse Assistant Training Program (NATP).

Certain topics must be taught before a student has direct resident contact: communication and interpersonal skills, infection control, safety and emergency procedures, promoting resident independence, and respecting resident rights. The 100 clinical hours must occur in an approved clinical setting under instructor supervision, and the RN Program Director attests that both the classroom and clinical requirements were met.

Eligibility and the Application Workflow

The baseline eligibility rules are short, but small paperwork errors cause most registry delays. To qualify, a candidate must:

• Be at least 16 years old.
• Complete a CDPH-approved 160-hour training program (or qualify through an approved equivalency / reciprocity path).
• Clear a criminal background check via Live Scan fingerprinting.
• Pass both parts of the competency evaluation — the written knowledge test and the manual skills test.

Core Forms

CDPH instructs paper applicants to submit the CDPH 283B Initial Application when they enroll in training, not after they finish. Your training program usually helps coordinate the 283B and the TMU account, but you should personally verify that your legal name, date of birth, email, and contact details are spelled identically everywhere. A mismatch between your CDPH record and your TMU record is a leading cause of delayed registry placement.

Live Scan and Background Review

Live Scan is electronic fingerprinting submitted on form BCIA 8016, and a copy must accompany the application package. The prints are run against both California Department of Justice and FBI databases, so results can take longer than the exam itself. CDPH reviews the criminal history. A record does not automatically mean denial — CDPH evaluates each case on its facts — but candidates with concerns should contact CDPH early rather than after passing the exam, because clearance must be in place before the registry status is issued.

Submitting the Live Scan as soon as you enroll, rather than waiting until you pass, is the single best way to avoid a gap between passing and certification.

A Pre-Scheduling Checklist

Before you book a test date in TMU, confirm every item below; any one of them can stall registry placement:

1. Training completion is entered by your program.
2. Your TMU account profile is complete and accurate.
3. Your CDPH 283B Initial Application was submitted.
4. Your Live Scan (BCIA 8016) was completed under the correct legal name.
5. Your name and date of birth match across CDPH, TMU, and your photo ID.
6. You know which IDs and forms to bring to check-in.

Reciprocity and Renewal

Reciprocity for Out-of-State CNAs

A nurse assistant who is already certified in another state may obtain California certification by reciprocity rather than repeating a full 160-hour program. The candidate files the CDPH 283E Equivalency/Reciprocity Application and must be currently listed on another state's registry as active and in good standing, consistent with the competency-evaluation requirements of OBRA '87. Proof is a copy of the out-of-state certificate, a screenshot of active registry status, or a CDPH 931 verification completed by the endorsing state. Live Scan background clearance is still required.

Two-Year Renewal Cycle

Once certified, a California CNA certificate is valid for two years. Renewal requires documented 48 hours of in-service training or continuing education units (CEUs) during the certification period, with at least 12 hours each year. Up to 24 of those hours may come from CDPH-approved online providers. Renewal also depends on maintaining eligibility, including continued background clearance and, in many cases, paid nursing-related work documentation.

Renewal Recordkeeping Habits

• Keep copies of all CEU certificates and in-service rosters.
• Track hours per year so you never fall short of the 12-hour annual floor.
• Update CDPH promptly after a legal name change or address change.
• Do not wait until your expiration month to discover missing hours — lapsed certificates can require additional steps to reinstate.

Exam Takeaway

For study purposes, memorize the headline numbers: 160 training hours (60 + 100), age 16, CDPH certifies and runs the registry, D&S Headmaster runs the exam, and renewal is 48 hours over two years (≥12/year). These appear in Role and Responsibility questions and frame every other topic in the guide.
