What you need to do to become a certified nursing assistant

A CNA license (Certified Nursing Assistant) requires you to complete a state-approved training program, pass a written exam, and pass a skills test. The whole process typically takes two to four months, depending on whether you attend full-time or part-time classes. Unlike a driver's license, a CNA license is issued by your state's nursing board, not a motor vehicle department, and you must renew it every two years in most states.

The path is straightforward: find an approved program, complete the coursework, register for your state's exam, take both the written and practical tests, and submit your results to your state board. Each state sets its own rules about program length, exam content, and renewal requirements, so the exact steps depend on where you live and work.

Key Takeaways

  • CNA training programs are offered by community colleges, hospitals, vocational schools, and some high schools, and typically run 4 to 12 weeks depending on whether you attend full-time or part-time.
  • Your state's nursing board approves training programs and administers the certification exam, so you must check your state board's website to find programs in your area.
  • The exam has two parts: a written test covering patient care and safety, and a skills demonstration where you perform five tasks in front of a proctor.
  • Most states require you to renew your CNA license every two years, usually by paying a renewal fee and sometimes by completing continuing education hours.
  • Some employers offer on-the-job CNA training after you are hired, though you still must pass the state exam to use the CNA title.

Finding and choosing a CNA training program

Start by visiting your state's nursing board website — search "[your state] nursing board" or "[your state] board of nursing" — and look for a section on CNA programs or approved training providers. The board lists all programs it has approved in your state. Community colleges offer the most programs and are often the cheapest option, ranging from $500 to $2,000 for the full course. Hospitals sometimes run their own programs, vocational schools and technical colleges offer them, and some high schools have CNA training for students.

When comparing programs, check whether they are full-time (usually 4 to 6 weeks) or part-time (8 to 12 weeks), what the tuition costs, whether they include exam registration fees, and whether they offer job placement help after you finish. Ask whether the program guarantees you can take the exam right after graduation or whether there is a waiting period. Some programs schedule exam dates monthly; others only a few times a year. If you need to work while training, a part-time evening or weekend program may fit better, even if it takes longer.

What CNA training covers

CNA programs teach patient hygiene and grooming, how to move and transfer patients safely, vital signs (blood pressure, temperature, pulse, respiration), catheter care, infection control, and how to communicate with patients and nursing staff. You will spend time in a classroom learning theory and anatomy, and time in a lab or clinical setting practicing hands-on skills on mannequins and real patients under supervision.

The training emphasizes safety — both yours and the patient's — because CNAs do physical work that can cause injury if done wrong. You will learn proper body mechanics to avoid hurting your back, how to recognize signs of patient distress, and when to report problems to a nurse. Most programs also cover basic patient rights, confidentiality, and how to work as part of a healthcare team.

Registering for and taking the CNA exam

After you finish your training program, you register for your state's CNA exam through your state nursing board. Some programs register you automatically as part of their service; others require you to register yourself. The registration fee varies by state but typically ranges from $100 to $300. You will need your Social Security number, proof of citizenship or legal residency, and proof that you completed an approved training program.

The exam has two parts, given on the same day or within a few days of each other. The written exam is multiple-choice, usually 60 to 100 questions, and covers patient care, safety, infection control, and communication. You typically have one to two hours to finish. The skills exam is a practical test where you perform five randomly selected tasks from a list of about 25 — examples include taking blood pressure, helping a patient bathe, or transferring a patient from bed to chair. A proctor watches and scores you on technique, safety, and communication. You must pass both parts to earn your license.

If you fail either part, you can retake it. Most states allow you to retake the exam within 30 to 90 days, though you may have to pay the registration fee again. Some states limit how many times you can retake it in a year.

Getting your license after passing the exam

Once you pass both parts of the exam, your state nursing board issues your CNA license. This usually takes two to four weeks. You will receive a certificate or license card in the mail with your license number, which you need to show employers. Some states allow you to print a temporary license from the board's website while you wait for the official one.

You can now legally use the title "Certified Nursing Assistant" and work in hospitals, nursing homes, clinics, home health agencies, and other healthcare settings. Your employer will ask for your license number when you are hired, and some employers verify it directly with the state board.

Renewing your CNA license

Most states require you to renew your CNA license every two years. Renewal usually involves paying a fee (typically $50 to $150) and submitting a renewal form to your state nursing board. Some states require you to complete continuing education hours — often 12 to 20 hours over the two-year period — through approved courses on topics like patient safety, infection control, or communication.

Your state board will send you a renewal notice a few months before your license expires. You can renew online, by mail, or in person, depending on your state. If your license expires and you do not renew it, you cannot legally work as a CNA until you renew it, though the process to renew an expired license is usually the same as renewing an active one.

What happens if you move to another state

CNA licenses are state-specific, so if you move, you will need to get licensed in your new state. Some states have reciprocity agreements that let you transfer your license with minimal extra steps — usually just paying a fee and submitting paperwork. Other states require you to retake the exam or complete additional training that meets their standards.

Before you move, contact your new state's nursing board and ask what is required to transfer or obtain a CNA license there. Some states accept licenses from other states automatically; others have different exam content or training requirements. Planning ahead can save you time and money.

Frequently Asked Questions

Do I need a high school diploma or GED to become a CNA?

Most states require a high school diploma or GED, though some programs accept students without one if they are working toward it. Check with your state nursing board and the specific program you are interested in, as requirements vary.

Can I work as a CNA while I am still in training?

Some states allow you to work as an unlicensed nursing assistant or patient care technician while you are in training or waiting for exam results, but you cannot use the title "Certified Nursing Assistant" until you pass the exam and receive your license. Ask your employer what roles are available before certification.

How much does CNA training cost?

Training costs range from $500 to $2,500 depending on the program length and provider. Community colleges are usually cheaper than private schools. Some employers offer tuition reimbursement or pay for training if you agree to work for them after you are licensed.

What if I fail the CNA exam?

You can retake the exam, usually within 30 to 90 days. Most states allow multiple retakes within a year, though you may have to pay the registration fee each time. Some programs offer free or low-cost review classes to help you prepare for a retake.

Is a CNA license the same as a nursing degree?

No. A CNA license is a certification that takes a few months to earn and qualifies you to information nurses with patient care. A nursing degree (RN or LPN) requires one to four years of college and leads to a different license. Many people earn their CNA first, then go back to school for nursing.
