CNA training typically takes a few weeks to a few months, with most state-approved programs running roughly 4 to 12 weeks depending on the schedule and the state’s minimum requirements. After the program, you take a state competency exam with a written portion and a skills demonstration, and once you pass you are placed on the state nurse aide registry. Counting the exam and registry processing, the full path from first class to working as a certified nursing assistant is often two to four months. Program length varies by state and school; licensing and certification requirements vary by state, so check your state’s nurse aide registry or health department.
| Stage | Typical length | Notes |
|---|---|---|
| State-approved CNA program | Often 4 to 12 weeks | Classroom, skills lab, and supervised clinical practice; varies by state and program |
| Part-time or evening program | Often 2 to 4 months | Varies by program |
| State competency exam | Scheduled within weeks of finishing | Written (or oral) test plus a skills demonstration |
| Registry listing | Days to a few weeks after passing | Placement on the state nurse aide registry; varies by state |
| BLS median pay (May 2025) | $42,260 | SOC 31-1131, Nursing Assistants |
CNA training is short because the credential is narrow and well defined. Federal rules for nurse aides working in Medicare- and Medicaid-certified nursing facilities set a minimum training standard, and each state builds its own approved-program requirements beyond it. The result is a program that most full-time students complete in one to three months, with the exam and registry steps adding a few more weeks.
Where you fall in the range depends on three things. The first is your state: some states set minimums close to the federal floor, while others require considerably more training time, which lengthens every program in that state. The second is scheduling: a full-time daytime course at a community college or vocational school moves faster, while evening and weekend courses stretch the same content over two to four months. The third is where the training happens: some nursing homes and hospitals run their own programs for new hires, which can be scheduled around work.
| Route | Typical length | What it includes |
|---|---|---|
| Community college or vocational school CNA course | Often 4 to 12 weeks | Classroom instruction in basic nursing skills, infection control, patient rights, and safety; a skills lab; and supervised clinical practice in a long-term care facility; leads to eligibility for the state competency exam |
| Employer-based program (nursing home or hospital) | Often 4 to 8 weeks | The same state-approved curriculum delivered by the employer, sometimes with wages paid during training; varies by employer and state |
| Nonprofit or community programs (for example, American Red Cross chapters) | Often 4 to 8 weeks | State-approved curriculum in a classroom and clinical format; availability varies by area |
| High school health occupations track | Often one school year | CNA training embedded in a high school program; students take the state exam near graduation; varies by district and state |
Whatever the route, the program has to be approved by the state for its graduates to sit for the competency exam. Ask any program for its state approval status before enrolling.
Clinical placement. Programs must place students in a facility for supervised clinical hours. In areas where several schools share the same nursing homes, clinical days may be scheduled later than the classroom portion, which extends the calendar.
Part-time schedules. Evening and weekend courses commonly take two to four months rather than one to two.
Prerequisites. Most programs require a background check, immunizations or a TB test, and sometimes a physical exam and CPR card before clinicals. Gathering these can add a few weeks, especially if immunization records are hard to locate.
Exam scheduling. The state competency exam is offered on set dates at testing sites, and seats can fill. A failed skills or written portion means retesting that section, and states limit the number of attempts before retraining is required.
State minimums. States with higher training-hour minimums have longer programs across the board. Program length varies by state; check your state’s requirements.
Prior training or experience. Some states allow nursing students who have completed a fundamentals course, or people with certain military medical training, to challenge the competency exam without completing a full CNA program. Rules vary by state; check your state registry.
Full-time daytime enrollment. The surest way to finish at the shorter end of the range.
Employer-based training. Employer programs tend to run continuously and schedule clinicals in the same facility, which avoids placement delays. They may also pay wages during training.
Reciprocity. If you already hold an active CNA credential in another state, most states allow transfer to their registry without retraining, though some require a new exam or a verification process. Rules vary by state.
There is no route that skips the state competency exam for a first-time CNA, and no state-approved program can be completed in a few days.
Each state administers, or contracts out, a nurse aide competency exam with two parts: a written test (an oral version is generally available for candidates with reading difficulties) and a skills demonstration in which you perform a small set of randomly selected nursing assistant tasks in front of an evaluator. Passing both places you on the state nurse aide registry, which employers check before hiring.
Credentials and next steps commonly associated with CNAs:
Certification and registry requirements vary by state; check your state nurse aide registry for the current exam, renewal, and reciprocity rules.
| Occupation | BLS median (May 2025) | Projected growth 2024-34 | Openings per year |
|---|---|---|---|
| Nursing Assistants (SOC 31-1131) | $42,260 | 2.3 percent | About 204,100 |
According to BLS Occupational Employment and Wage Statistics, May 2025, the median annual wage for nursing assistants was $42,260. The lowest 10 percent earned less than $33,940, and the top 10 percent of earners made more than $51,980. According to BLS Employment Projections, 2024-34, employment of nursing assistants is projected to grow 2.3 percent, with about 204,100 openings per year on average, largely because of turnover in a very large occupation. Pay varies by employer, location, experience, and credentials; individual outcomes may vary.
Nursing homes and skilled nursing facilities employ the largest share of CNAs, with hospitals, assisted living, and home health next. Hospital positions often pay more and can be harder to get without experience.
Not in most states. Even states with minimums near the federal floor have programs that generally run at least three or four weeks once clinical hours are scheduled, and many states require more. Program length varies by state; check your state’s approved program list.
Sometimes. Nursing homes and hospitals that run their own programs may pay trainees a wage during training in exchange for a work commitment. School-based programs do not pay students.
The written portion is usually completed in about an hour or two, and the skills portion takes roughly half an hour, though formats vary by state and testing vendor. Results for the written test are often available the same day; the skills portion is scored by the evaluator on site.
Most states keep a CNA on the registry as long as they document a certain amount of paid nursing assistant work within a set period, commonly every two years. Letting the credential lapse usually means retesting or retraining. Rules vary by state.
Generally not as credit. A few nursing programs waive a fundamentals lab for CNAs, but the nursing curriculum and clinicals still have to be completed. CNA experience is more useful for admission preferences and for confirming that bedside care is the right fit before committing to a longer program.
