How to Become a CNA
A Certified Nursing Assistant (CNA) is often the fastest way to start working in hands-on patient care, and for many people, it’s also the first step on a longer path toward becoming an LPN or RN later. Here’s how the process generally works.
Requirements vary by state. Always confirm current details with your state’s CNA registry or nurse aide certification program before enrolling.
What a CNA actually does
CNAs provide direct, hands-on care under the supervision of licensed nurses, helping patients bathe, dress, eat, and move; taking vital signs; and reporting changes in a patient’s condition to the nursing team. It’s physically active work and often a person’s first real exposure to clinical care.
Step 1: Complete a state-approved training program
CNA programs are typically offered through community colleges, technical schools, and sometimes hospitals or long-term care facilities. Programs usually run anywhere from a few weeks to a couple of months and combine classroom instruction with supervised clinical practice.
Step 2: Pass a competency exam
After finishing training, candidates take a state competency exam, which usually includes both a written (or oral) portion and a skills demonstration where you perform hands-on care tasks under observation.
Step 3: Get listed on your state’s CNA registry
Passing the exam typically results in your name being added to your state’s official nurse aide registry. This is what makes you “certified” and legally able to work as a CNA in that state.
Step 4: Keep your certification active
Most states require CNAs to work a minimum number of hours within a set period and/or complete continuing education to keep their certification active. Certifications that lapse for too long may require retesting.
Where CNAs work
Hospitals, nursing homes and long-term care facilities, assisted living communities, home health agencies, and rehabilitation centers are all common workplaces.
What comes next
Many CNAs use the role as a stepping stone; the hands-on experience is valuable preparation for LPN or RN programs, and some employers offer tuition assistance to CNAs who want to continue their education. If that’s your goal, take a look at our guides on becoming an LPN/LVN or becoming an RN.
