Getting a CNA license requires passing a state exam, but the path to that exam varies by state

A Certified Nursing Assistant (CNA) license is not a single national credential. Each state issues its own, and each state sets its own rules about training hours, exam content, and renewal. Most states require you to complete a training program (usually 75 to 150 hours), pass a written exam, and pass a skills test. Some states let you test when ready after training; others require a waiting period or additional documentation. A few states recognize reciprocity — meaning they accept a CNA license from another state — but most do not, so moving to a new state often means retesting.

The fastest route is to contact your state's nursing board directly, because they publish the exact requirements for your state and can tell you which training programs they have approved. You can find your state board through the National Council of State Boards of Nursing (NCSBN) website, which lists all 50 boards and links to their requirements pages.

Key Takeaways

  • Most states require 75 to 150 hours of classroom and hands-on training from an approved program before you can sit for the CNA exam.
  • The written exam and skills test are administered by your state nursing board or a testing vendor they contract with, not by the training program itself.
  • Some states let you test when ready after training; others require a waiting period, a background check, or proof of CPR certification before you can register for the exam.
  • CNA licenses must be renewed every two to four years depending on your state, and renewal requirements vary — some states require continuing education, others do not.
  • If you move to a new state, you usually must retake the exam in that state, though a few states have reciprocity agreements that may shorten the process.

Finding an Approved CNA Training Program in Your State

Your state nursing board maintains a list of approved training programs. These are typically offered by community colleges, vocational schools, hospitals, and some private training centers. The program must meet your state's minimum hour requirement and cover the topics your state's exam will test. Most programs run 4 to 12 weeks if you attend full-time, or longer if you attend part-time.

When you contact a program, ask whether they are approved by your state board and whether their graduates pass the state exam at a high rate. Some programs publish their pass rates; if they do not, ask directly. You should also ask what is included in tuition — some programs bundle CPR certification, others charge separately. A few states require CPR certification before you can sit for the CNA exam, so confirm whether your state is one of them.

Cost varies widely. Community college programs typically cost $500 to $2,000. Private programs may cost $1,500 to $4,000. Some hospitals offer free or subsidized training if you commit to working there for a set period after licensure. Ask whether your state offers any grants or scholarships for CNA training; a few do, though they are not common.

What the Training Program Covers

All approved CNA programs cover basic patient care, infection control, patient safety, communication, and the legal and ethical duties of a CNA. You will learn how to help patients with activities of daily living — bathing, dressing, toileting, eating — and how to take vital signs like blood pressure and temperature. Most programs include both classroom hours and supervised clinical practice, usually in a hospital or nursing home.

The clinical portion is where you practice skills under supervision. Your instructors will evaluate whether you can perform tasks correctly and safely. This evaluation is separate from the state skills exam you will take later, but it prepares you for it. Some programs require you to demonstrate competency in specific skills before they will sign off on your training completion certificate, which you will need to register for the state exam.

Registering for and Taking the State Exam

After you finish your training program, you will receive a completion certificate or letter from the program. This is your proof that you met your state's training requirement. You then register for the state exam through your state nursing board or the testing vendor they use. Most states use Pearson Vue or Prometric as their testing vendor.

Registration usually requires your training completion certificate, a government-issued photo ID, and payment of an exam fee (typically $100 to $200). Some states require additional documentation, such as proof of CPR certification, a background check clearance, or a health screening. Check your state board's website for the complete list before you register, because missing a requirement can delay your exam date.

The written exam is usually 60 to 100 multiple-choice questions covering the topics taught in your training program. You typically have two to three hours to complete it. The skills test involves performing five to six nursing tasks — such as taking blood pressure, helping a patient into bed, or providing personal hygiene — in front of an examiner. You must perform each task correctly and safely to pass. Most states allow you to retake the exam if you fail, though you may have to pay the fee again and wait a set period before retesting.

State-by-State Differences in Requirements and Timelines

Training hour requirements range from 75 hours (in some states) to 150 hours (in others). A few states have no minimum hour requirement but instead require you to pass the exam and meet other conditions. Exam content is standardized across most states through the NCSBN, but some states add state-specific questions about their own regulations.

Waiting periods between training completion and exam registration vary. Some states let you register when ready; others require a waiting period of 30 to 60 days. A handful of states require a background check before you can sit for the exam. A few states require proof of a negative tuberculosis test or other health screening. These requirements change, so always check your state board's website before you finish training.

Processing times also vary. Some states issue your license within days of passing the exam; others take two to four weeks. A few states issue a temporary license while they process your permanent one, which lets you start working when ready. Ask your state board whether they offer this option.

Renewing Your CNA License

CNA licenses expire every two to four years depending on your state. Most states require you to renew before the expiration date, though some allow a grace period of 30 to 90 days. Renewal usually costs $50 to $150 and can often be done online through your state board's website.

Renewal requirements vary significantly. Some states require continuing education — typically 12 to 20 hours of approved training — to renew. Others require proof that you have worked as a CNA for a minimum number of hours in the past two years. Some states require both. A few states have no renewal requirements beyond paying the fee. Check your state board's website to learn what your state requires and when your license expires.

Moving to Another State With Your CNA License

Most states do not recognize a CNA license from another state, which means you will need to retake the exam in your new state. However, a few states have reciprocity agreements or streamlined pathways for CNAs licensed in other states. These agreements are rare and change over time, so contact your new state's nursing board to ask whether they recognize your current license or offer any shortened process.

If reciprocity is not available, you will typically need to complete a training program in your new state (or show that your previous training meets their requirements) and then pass their exam. Some states will waive the training requirement if you can show proof of recent work experience as a CNA, but this varies. The fastest approach is to contact your new state's nursing board before you move and ask what documentation they need from your current state.

Frequently Asked Questions

Can I work as a CNA before I get my license?

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. These roles have different titles and fewer restrictions than a CNA, but they pay less and have limited scope. Ask your employer and your state board what is allowed in your state.

What happens if I fail the CNA exam?

You can retake it, usually after paying the exam fee again and waiting a set period — often 24 hours to 30 days depending on your state. Some states limit how many times you can retake the exam in a year. Your training program may offer review classes to help you prepare for a second attempt.

Do I need CPR certification to become a CNA?

Some states require it before you sit for the CNA exam; others do not. Check your state board's requirements. If it is required, your training program may include CPR training, or you may need to get it separately through the American Red Cross or American Heart Association.

How long does it take to get a CNA license from start to finish?

If you attend a full-time program, you can complete training in 4 to 12 weeks, then take the exam within days or weeks after that. Total time from enrollment to licensure is typically 2 to 4 months, though it can be longer if your state has a waiting period or if you do not pass the exam on your first attempt.

Can I get a CNA license online?

The classroom portion of training can often be done online, but the clinical skills portion must be done in person under supervision. Most programs offer a hybrid model where you take classes online and do clinical practice at a hospital or nursing home. A few states may allow the entire program online if it meets their requirements, but this is uncommon.
