A CNA, or Certified Nursing Assistant, is not technically a nurse. It’s a healthcare role that works alongside nurses, providing hands-on patient care under the supervision of registered nurses (RNs) and licensed practical nurses (LPNs). The term “CNA nurse” gets used colloquially, but the distinction matters: CNAs have a more limited scope of practice, shorter training requirements, and less clinical authority than licensed nurses. That said, they are often the healthcare workers who spend the most time with patients, handling the essential daily care that keeps people comfortable and safe.
What a CNA Actually Does
The core of a CNA’s job revolves around helping patients with activities of daily living, the fundamental tasks people need to stay alive and well. This includes bathing, grooming, toileting, dressing, eating, and moving from place to place. In a nursing home, that might mean helping a resident get out of bed each morning, assisting them to the bathroom, and making sure they can eat their meals. In a hospital, it could mean repositioning a patient every two hours to prevent bedsores or walking them down the hall after surgery.
Beyond personal care, CNAs handle a range of supportive clinical tasks. They take vital signs like blood pressure, pulse, and temperature. They record food and fluid intake. They observe and report changes in a patient’s condition to the nursing staff. This observation role is critical because CNAs spend far more face-to-face time with patients than RNs or doctors typically do, making them the first to notice when something changes.
What CNAs cannot do is equally important to understand. They generally cannot administer medications, insert IVs, create care plans, or perform complex wound care. Some states allow experienced CNAs who complete additional coursework to assist with medication administration under direct nurse supervision, but this is the exception. If a task isn’t on a state’s approved CNA skills list, the CNA is prohibited from performing it, regardless of experience.
How CNAs Differ From RNs and LPNs
The biggest difference is education. Becoming an RN requires a two-year associate degree or a four-year bachelor’s degree from an accredited university. CNA programs often take less than one year and don’t require any college education. They focus heavily on direct clinical experience rather than coursework, which makes the role one of the fastest entry points into healthcare.
The difference in authority follows from this. RNs have significant autonomy: they assess patients, develop care plans, administer medications, and make clinical decisions. CNAs work as assistants to RNs and other medical providers, carrying out tasks that have already been planned and approved by a licensed nurse. An LPN falls somewhere in between, with more training than a CNA and the ability to perform tasks like medication administration, but still working under RN oversight in most settings.
Training and Certification Requirements
Federal law requires CNA training programs to include at least 75 clock hours of instruction, with a minimum of 16 hours spent in supervised practical training. During the practical portion, trainees demonstrate their skills on real individuals under the direct supervision of a registered nurse or licensed practical nurse. Many states set their own requirements above the federal minimum, so the total training hours you’ll need depends on where you live.
After completing a state-approved training program, you must pass a certification exam. The exam has two parts: a written (or oral) knowledge test and a hands-on skills evaluation. The skills portion tests you on tasks drawn from a list of roughly 20 to 25 essential competencies. These include hand washing technique, assisting a patient to walk using a transfer belt, helping with bedpan use, applying compression stockings, and cleaning dentures. You’ll be asked to perform a random selection of these skills in front of an evaluator, demonstrating proper technique and patient safety throughout.
Once certified, your name goes on your state’s nurse aide registry, which employers check before hiring. Most states require CNAs to complete continuing education and work a minimum number of hours to maintain active certification.
Where CNAs Work
Nursing homes and long-term care facilities employ a large share of CNAs, which makes sense given that residents in these settings need daily help with bathing, dressing, and mobility. Hospitals are another major employer, where CNAs support nursing staff on medical, surgical, and rehabilitation units. Home health care is a growing area as well, with CNAs visiting patients in their homes to provide personal care and monitor their condition between nurse or doctor visits.
Assisted living facilities, rehabilitation centers, and hospice programs also hire CNAs. The day-to-day work varies by setting. A CNA in a hospital may care for several patients across a fast-paced shift, while a home health CNA might spend an entire visit with one person, helping them bathe and preparing a meal.
Pay and Job Outlook
The median annual wage for nursing assistants was $39,530 as of May 2024, according to the Bureau of Labor Statistics. That breaks down to roughly $19 per hour. The lowest 10 percent earned less than $31,390, while the highest 10 percent earned more than $50,140. Pay varies by state, employer type, and shift. Night and weekend shifts often come with differential pay, and CNAs in hospitals tend to earn more than those in nursing homes.
Demand for CNAs remains steady. An aging population means more people need assistance with daily living, both in facilities and at home. The role also has high turnover, which means job openings are consistently available in most regions.
Career Advancement Options
Many people use the CNA role as a stepping stone into nursing. Bridge programs exist specifically for CNAs who want to become LPNs or RNs, and your hands-on experience can give you a practical advantage in nursing school. A CNA-to-LPN bridge program typically requires your active CNA certification, a few prerequisite college courses in biology and English, and a minimum GPA of 2.0. From there, you can continue into an RN program if you choose.
Even without pursuing a nursing degree, experienced CNAs can specialize. Some become certified medication aides after additional training. Others move into supervisory roles, training new CNAs or coordinating care on a unit. The clinical experience you gain as a CNA, learning to read patients, anticipate needs, and work within a healthcare team, translates directly into nearly every other healthcare career path.
