A nurse’s assistant, most commonly called a certified nursing assistant (CNA), is a healthcare worker who provides hands-on basic care to patients under the supervision of nurses. CNAs handle the daily physical needs that patients can’t manage on their own, from bathing and dressing to checking vital signs and helping with meals. They work in nursing homes, hospitals, assisted living facilities, and home health settings, serving as the closest point of contact between patients and the rest of the care team.
What a Nursing Assistant Actually Does
The core of the job revolves around what healthcare professionals call “activities of daily living,” the basic tasks a person needs to get through each day. Nursing assistants clean and bathe patients, help them use the toilet and get dressed, serve meals and assist with eating, and move patients between beds and wheelchairs. These tasks are physically demanding and repetitive, often performed for multiple patients across a single shift.
Beyond personal care, nursing assistants also handle a layer of clinical monitoring. They measure vital signs like blood pressure and temperature, listen to patients’ health concerns, and report that information back to the supervising nurse. This reporting role is critical. Because CNAs spend more direct time with patients than any other staff member, they’re often the first to notice changes in a patient’s condition, whether that’s a new complaint, a shift in mood, or a reading that looks off.
What nursing assistants cannot do is equally important to understand. They don’t diagnose conditions, create care plans, or independently make clinical decisions. In most states, they cannot administer medications, perform wound care, or manage catheters. However, roughly 22% of states do allow CNAs to be delegated some of these expanded tasks, such as witnessing and documenting a resident taking medications. The exact boundaries depend on your state’s scope of practice laws.
Training and Certification Requirements
Federal law requires a minimum of 75 clock hours of training for anyone working as a nursing assistant in a Medicare- or Medicaid-certified facility. At least 16 of those hours must be supervised practical training, where the student demonstrates skills on a real person under the direct supervision of a registered nurse or licensed practical nurse. This can take place in a lab setting or a clinical environment.
In practice, most states require more than the federal minimum. State-approved CNA training programs commonly range from 75 to 180 hours depending on location, and many community colleges and vocational schools offer programs that can be completed in four to twelve weeks. The coursework covers infection control, patient safety, communication, nutrition basics, and the hands-on care skills you’ll be tested on.
After completing a state-approved training program, you must pass a certification exam before you can work. The national standard is the National Nurse Aide Assessment Program (NNAAP), which has two parts: a written (or oral) portion and a skills demonstration. The oral option is available in English and Spanish. You need to pass both components, after which your name is added to your state’s nurse aide registry. Most states require renewal every two years, along with proof of recent work experience in the field.
Pay and Job Availability
As of May 2023, the median hourly wage for nursing assistants was $18.36, which works out to about $38,200 per year. Pay varies significantly by setting and geography. Hospital-based CNAs typically earn more than those in long-term care facilities, and wages in metropolitan areas and states with higher costs of living tend to be well above the national median.
Demand for nursing assistants remains consistently strong. An aging population means more people need assistance in nursing homes, rehab centers, and home health environments. Turnover in the field is also high due to the physical demands and relatively modest pay, which means openings are frequent. For someone looking to enter healthcare quickly, it’s one of the most accessible entry points available.
Where Nursing Assistants Work
The largest employer of CNAs is the long-term care sector: nursing homes, skilled nursing facilities, and assisted living communities. In these settings, CNAs often care for the same residents over weeks or months, building ongoing relationships and becoming deeply familiar with each person’s needs and habits.
Hospitals employ nursing assistants as well, where the pace is faster and the patient population changes constantly. Hospital CNAs may work on medical-surgical floors, in emergency departments, or in specialized units. Home health is another growing sector, where CNAs travel to patients’ homes to provide one-on-one care. This setting offers more autonomy but also requires more independence, since a supervising nurse isn’t physically present at all times.
Career Advancement From CNA
Many people use the CNA role as a stepping stone into other nursing careers. The most common path is through a bridge program, which lets you build on your existing training and clinical experience rather than starting from scratch. CNA-to-RN bridge programs typically take one to two years and include courses in nursing theory, health assessment, and clinical practice.
The full educational pathway to becoming a registered nurse involves completing an accredited nursing program (either an associate or bachelor’s degree) and passing the NCLEX-RN licensing exam. Depending on the degree, that process takes anywhere from 10 to 60 months. Some CNAs take an intermediate step first, becoming a licensed practical nurse (LPN) before pursuing an RN credential. Others move laterally into specialized aide roles, such as working in physical therapy or surgery support, which may come with additional on-the-job training and higher pay.
The hands-on patient experience CNAs accumulate is a genuine advantage in nursing school. You’ll already understand how a healthcare facility operates, how to interact with patients in vulnerable moments, and how care teams communicate. That practical foundation is something classroom-only students don’t have.
