Certified Nursing Assistant (CNA) exam rules differ across the U.S. In 2026, each state sets its own requirements for training hours, testing, and application. This guide highlights the key CNA exam requirements by state in 2026.
What are the minimum CNA training hours required?
Most states require 75–150 hours of CNA training.
Federal law mandates at least 75 hours, but states such as California require 160 hours. Training includes classroom instruction and hands-on clinical practice.
How old do you need to be to take the CNA exam?
The minimum age is usually 16–18 years old depending on the state.
Some states allow younger students in high school CNA programs, while others require candidates to be at least 18 to apply for certification.
Do you need a high school diploma to take the CNA exam?
Not always. Many states allow CNA training without a diploma.
However, employers often prefer candidates with a high school diploma or GED. States may also require proof of English proficiency for exam eligibility.
What health checks are required for CNA candidates?
Most states require TB testing, immunizations, and a physical exam.
These ensure candidates can safely provide care. Some states also mandate drug screening or vaccination proof before allowing exam registration.
Is a background check required to sit for the CNA exam?
Yes. All states require a criminal background check.
Applicants with certain criminal convictions may be denied certification. Requirements vary, but fingerprinting fees usually range from $30–$75.
What is the CNA exam format in 2026?
The exam includes a written test and a skills demonstration.
Most written sections have 60–70 multiple-choice questions. The skills portion requires candidates to perform 3–5 randomly selected CNA skills under examiner observation.
How much does it cost to take the CNA exam?
The CNA exam typically costs $100–$300 in 2026.
Fees cover the written and skills tests. Some states charge separately for application, licensing, and retesting. Costs vary depending on the testing provider and state board.
Do requirements differ significantly by state?
Yes. Training hours, application steps, and fees vary across the U.S.
For example:
- California: 160 hours of training, live scan background check.
- Texas: 100 hours of training, state registry application.
- New York: 75 hours of training, state-specific written exam.
