No, you do not have to be 18 to be a CNA in most states. Federal law sets training standards for nursing assistants but does not impose a nationwide minimum age, so each state’s board of nursing or health department decides. A majority allow enrollment in an approved training program at 16 or 17, some require candidates to turn 18 before sitting for the competency exam, and a handful insist on 18 for every step. The practical result is a patchwork: a 16-year-old in one state might already be working bedside shifts while a peer across the border is still waiting to enroll.
How the Age Rules Actually Work
The Omnibus Budget Reconciliation Act of 1987 created the federal framework for nurse aide training and registry requirements, but it is silent on age. The implementing regulations at 42 CFR Part 483 spell out minimum training hours, competency evaluation standards, and registry obligations without ever specifying how old a candidate must be. That gap hands full authority to the states, and they have gone in different directions.
The important thing to understand is that becoming a CNA is not a single event. There are three separate gates, and your state may set a different minimum age for each:
- Enrolling in a state-approved training program.
- Sitting for the competency evaluation after training.
- Being placed on the state’s Nurse Aide Registry, which is what employers check before hiring.
A candidate who is old enough to enroll may not yet be old enough to test, and a candidate who has passed the exam may still have to wait to appear on the registry. Before paying for any program, check your state’s nurse aide registry or board of nursing website for the exact age cutoffs at each of the three stages.
Starting CNA Training in High School
Many high schools and career-technical centers offer state-approved CNA courses as part of their health sciences curriculum, specifically designed for students who are 16 or 17. These programs fold the required classroom and clinical hours into the school schedule, and some allow students to sit for the competency exam before graduation. If the student is under 18, a parent or guardian typically signs a liability waiver before clinical rotations begin.
Federal regulations set the training floor at 75 hours, divided between classroom instruction and hands-on clinical practice.1eCFR. 42 CFR 483.152 – Requirements for Approval of a Nurse Aide Training and Competency Evaluation Program Many states raise this substantially, with total requirements ranging up to about 180 hours. Clinical rotations, where you practice skills on real patients under the supervision of a registered nurse, typically account for 16 to 100 of those hours. Most programs also require either a high school diploma, a GED, or current enrollment in high school.
The catch for minors is that passing the exam does not guarantee you can start working. Some clinical facilities and employers carry insurance policies that exclude workers under 18, which can delay actual employment regardless of what the state registry allows. If you are a high school student eyeing this route, contact both your state registry and the facilities where you hope to work. The registry tells you when you can certify; the employer tells you when you can start.
What a CNA Under 18 Is Not Allowed to Do
Holding a CNA certificate does not override federal child labor protections. The Fair Labor Standards Act restricts workers under 18 from tasks the Department of Labor considers hazardous, and one of those restrictions hits healthcare directly.2U.S. Department of Labor. Fact Sheet 43 – Child Labor Provisions of the FLSA for Nonagricultural Occupations
Hazardous Occupations Order No. 7 prohibits minors from operating any power-driven hoisting apparatus, including powered patient lifts like Hoyer lifts.3eCFR. 29 CFR 570.58 – Occupations Involved in the Operation of Power-Driven Hoisting Apparatus (Order 7) Before 2010, patient lifts were arguably exempt because they fell below the one-ton capacity threshold. A 2010 amendment removed the capacity exception, and powered patient lifts of any size are now off-limits for workers under 18.4Regulations.gov. Federal Child Labor Law Hazardous Occupations Order No. 7 Since mechanical lifts are standard equipment for transferring patients in nursing homes and hospitals, this restriction meaningfully limits what a minor CNA can do on the floor. You can be certified, on the registry, and on the schedule, and still need a coworker every time a patient needs to be lifted.
One common misconception is that federal law also caps the weekly hours a 16- or 17-year-old CNA can work. It does not. Federal hour restrictions under the FLSA apply only to workers under 16.2U.S. Department of Labor. Fact Sheet 43 – Child Labor Provisions of the FLSA for Nonagricultural Occupations Many states, however, impose their own hour and scheduling limits on workers under 18, including restrictions on overnight shifts and maximum hours during school weeks. Check your state’s child labor laws separately from the federal rules.
Confirming Your State’s Age Cutoffs Before You Enroll
Because federal law leaves age entirely to the states, general answers only get you so far. Two calls before enrollment will save you from paying for training you cannot use yet:
- Call the state agency that runs the Nurse Aide Registry (usually the state health department or board of nursing). Ask for the minimum age to enroll in an approved training program, the minimum age to sit for the competency exam, and the minimum age to be placed on the registry.
- Call the facilities where you would want to work. Ask whether their insurance covers CNAs under 18, and whether they schedule minors for the shift types you are hoping to work.
The training itself must come from a state-approved program; completing a non-approved course, no matter how thorough, will not qualify you to sit for the competency exam. If your high school offers a health sciences pathway, that is often the fastest route for a minor because the age eligibility, the training approval, and the clinical placement are already sorted out on your behalf.
