You can become a Certified Nursing Assistant in California starting at age 16. That is the floor set by state law, and there is no upper age limit. The catch is that meeting the CNA age requirements in California is not the same as being able to work a full CNA schedule: applicants who are 16 or 17 remain subject to child labor rules that cap their hours and block overnight shifts.
Who Qualifies at 16
Health and Safety Code Section 1337.2 lays out what every applicant needs regardless of age: be at least 16 years old, complete a state-approved training program, and obtain a criminal record clearance.1California Department of Public Health. CNA FAQ – Initial There is no high school diploma or GED requirement, and no upper age limit at all. What the state does expect is that you can read, write, and understand English well enough to absorb medical concepts and follow patient care instructions during training.
The training program itself runs 160 hours, split between 60 hours of classroom instruction and 100 hours of supervised clinical practice.2California Department of Public Health. Nurse Assistant Training Program Applicants A 16-year-old enrolls the same way an adult does, submits fingerprints through Live Scan at the time of enrollment, and sits for the same two-part competency exam at the end.1California Department of Public Health.

One point worth knowing before you apply: California has no automatically disqualifying criminal convictions for CNA certification.3California Department of Public Health. Certified Nurse Assistant The department reviews criminal history case by case, and a record can still lead to denial, but no single offense triggers an automatic bar. Applicants with a potentially disqualifying conviction have two years from the date the department receives the criminal record report to submit evidence of rehabilitation.4California Legislative Information. California Health and Safety Code – Article 9 Training Programs
How California Compares to Other States
California’s 16-year minimum is lower than most people expect. Federal rules for nurse aide programs under 42 CFR 483.152 do not set a national age minimum and leave the decision to each state.5eCFR. 42 CFR 483.152 – Requirements for Approval of a Nurse Aide Training and Competency Evaluation Program Some states require applicants to be 18. California does not.
Being old enough to apply is different from being old enough to work a typical CNA schedule, and that distinction matters most for anyone applying before their 18th birthday.
What Changes If You’re Under 18
California child labor law applies to certified nursing assistants under 18 the same way it applies to any other minor employee. All minors under 18 must obtain a work permit before starting a job.6California Department of Industrial Relations. Information on Minors and Employment The permit requirement alone can narrow the list of facilities willing to hire you, because healthcare employers often need staff available around the clock on short notice.
Hour limits are the bigger practical obstacle. During the school year, 16- and 17-year-olds may work up to four hours on a school day and eight hours on a non-school day, with a weekly cap of 48 hours. Work is generally permitted between 5:00 a.m. and 10:00 p.m., extending to 12:30 a.m. on evenings before a non-school day.7California Department of Industrial Relations. Summary Chart – Work Permits and Minor Labor Law Restrictions Overnight shifts, which are common in skilled nursing facilities, are off-limits.
Federal rules add another layer. The Department of Labor bars 16- and 17-year-olds from tasks classified as hazardous, including work involving exposure to radioactive substances or ionizing radiation.8U.S. Department of Labor. Fact Sheet 43 – Child Labor Provisions of the FLSA for Nonagricultural Occupations Most routine CNA duties fall outside those hazardous categories, but a minor working in a facility with certain imaging equipment could run into restrictions. In practice, many nursing homes and hospitals prefer to hire CNAs who are at least 18 simply to avoid scheduling complications.
When the Restrictions Lift
The hour restrictions come off before the 18th birthday for one group. High school graduates are exempt from the minor hour limits and may work the same schedule as an adult.7California Department of Industrial Relations. Summary Chart – Work Permits and Minor Labor Law Restrictions A 17-year-old who has already finished high school and earned CNA certification can take overnight and full-time shifts. A 17-year-old still in school cannot, no matter how the certification is dated.
Once you turn 18, the work permit requirement and hour caps no longer apply, and the only remaining requirements are the ones every California CNA carries: an active certification, a clean criminal record clearance, and absence from the federal Office of Inspector General’s List of Excluded Individuals and Entities, which bars work at any facility that bills Medicare, Medicaid, or other federally funded health programs.9Office of Inspector General. Background Information – Exclusions
If you are 16 or 17 and set on becoming a CNA, the sequence that works is to enroll in an approved training program, get your Live Scan fingerprints submitted at enrollment, pass the competency exam, obtain a work permit through your school, and then look for employers whose scheduling can accommodate a minor’s hours. If you are close to graduation, waiting a few months can open up the full range of shifts that most CNA jobs actually offer.
