CNA Exam

What Is the CNA Exam

The CNA exam is the competency evaluation a state uses to decide whether a trained nurse aide can be placed on its nurse aide registry. Federal rules for nursing homes require nurse aides to complete an approved training program and pass a competency evaluation, and each state runs its own testing program within those rules.

Passing the exam lets you work as a certified nursing assistant in long-term care facilities, hospitals, home health and assisted living. Employers check the registry before hiring, so the exam is the gateway between finishing your course and starting paid work.

Most candidates take the exam within a few weeks of finishing training, while skills are fresh. Our CNA practice test uses original questions in the same style as the written exam, so you can check your readiness before you book.

Who Runs the State Board CNA Exam

The state board or health department sets the rules, but a testing company usually delivers the exam. Many states use the National Nurse Aide Assessment Program (NNAAP), a standardized exam developed for state boards and delivered by Credentia. Other states contract with different administrators, such as Prometric or Headmaster (D&S Diversified Technologies), which publish their own candidate handbooks. Florida, for example, names Prometric as its contracted test administrator.

Because the vendor determines the format, the most important document for your exam is your state’s candidate handbook. It lists the number of questions, the skills that may be tested, the passing standard, the fees and the identification rules for test day.

CNA Exam Format

The CNA exam has two parts that you must pass separately: a written (or oral) knowledge test and a skills evaluation. The facts in the table at the top of this page come from the NNAAP candidate handbook published by Credentia; states with other vendors follow a similar two-part structure.

Written Test: 70 Multiple-Choice Questions

The NNAAP written examination has 70 multiple-choice questions, of which 60 are scored and 10 are pretest questions that do not count. You have 2 hours. Questions cover three areas of the nurse aide role:

• Physical care skills: activities of daily living, basic nursing skills and restorative skills.
• Psychosocial care skills: emotional and mental health needs and spiritual and cultural needs.
• Role of the nurse aide: communication, client rights, legal and ethical behavior and working as a member of the health care team.

Candidates who have difficulty reading English can request the oral version, in which the questions are read aloud. The oral exam adds a short reading comprehension section made up of job-related words.

States that do not use NNAAP set their own numbers. Florida’s Prometric written test, for example, has 60 multiple-choice questions in 90 minutes, according to the Florida Board of Nursing.

Clinical Skills Test

In the NNAAP skills evaluation you perform five randomly selected nursing assistant skills in 30 minutes while a nurse aide evaluator watches. According to Credentia, the five always include handwashing and a measurement skill, such as counting respirations or measuring blood pressure. Florida’s skills test also uses five randomly selected skills. Each skill has critical steps; missing one usually means failing that skill.

The evaluator plays the role of the resident or uses a volunteer. You are scored on what you do and say, so describe your actions as you go, knock and introduce yourself, explain the procedure and provide privacy every time.

Basic Nursing Skills

Basic nursing skills include taking and recording vital signs, measuring intake and output, collecting specimens, caring for residents with catheters and observing and reporting changes in condition. Expect written questions that ask what to report to the nurse and when.

Activities of Daily Living

Activities of daily living (ADLs) are the self-care tasks you help residents with: bathing, dressing, eating, toileting, grooming and moving. Questions focus on safety and dignity — for example, dressing the weaker side first, checking water temperature and encouraging residents to do as much as they can for themselves.

Vital Signs

Vital signs appear on both parts of the exam. Know the normal adult ranges, how to count a radial pulse and respirations for a full minute, how to read a manual blood pressure and which findings must be reported to the nurse immediately.

CNA Exam Scoring: How Many Questions Can You Miss

Each state sets the passing standard for its CNA exam, so there is no single national answer to how many questions you can miss. The written exam is reported as pass or fail, and you must pass both the written and skills parts to be certified. Your state handbook lists the exact passing score and how many attempts you are allowed.

If you fail one part, most states let you retest only that part, within limits on the number of attempts and the time since you finished training. Our practice test reports a percentage and a section breakdown against a 70% readiness benchmark, which helps you see whether you are consistently above a safe margin.

CNA Exam Registration and Fees

You usually register through the testing company your state uses, often after your training program confirms you have completed the course. Fees, payment methods and scheduling rules are set by each state and vendor, which is why the fee row in the table above reads “Not published by the exam body” at the national level.

In many states the training program or a future employer pays the exam fee. Federal rules also prevent nursing homes from charging nurse aides they employ for training and testing, so ask your employer before you pay yourself.

How to Prepare for the CNA Exam

The best preparation combines the written knowledge with hands-on rehearsal of every skill on your state’s list. A simple four-week plan works for most candidates who have just finished training:

Build your own version of this schedule with the study planner and keep track of your test date with the exam countdown.

CNA Practice Test Questions

Use timed CNA practice test questions to build pacing and study mode to learn from explanations. Every question in our bank includes the correct answer, an explanation and a short note on why the other options are wrong, so you learn the reasoning instead of memorizing answers.

CNA Practice Test Abbreviations

Charting abbreviations show up in written questions and on the job. Make a short deck of common ones — such as ADL, BP, I&O, NPO and PRN — with the flashcard maker and review it daily for a week before the exam.

Nursing Assistant Practice Test With Answers

A nursing assistant practice test with answers is most useful when you review it carefully. After each attempt, sort the questions you missed by topic and reread that section of your training manual before your next attempt.

State Exam Test Day Checklist

Arrive ready for both parts of the state exam. Check your state handbook for exact rules, and use this list as a starting point:

• Bring the identification your state requires, usually two forms with one government-issued photo ID, with names that match your registration.
• Bring your admission letter or confirmation if your vendor requires it.
• Wear comfortable, closed-toe shoes and clothing suitable for performing skills, such as scrubs.
• Arrive early; late arrivals may not be admitted and may lose their fee.
• Leave phones, smartwatches and notes outside the testing room.
• Before each skill, introduce yourself, identify the resident, explain the procedure and provide privacy.
• Finish each skill by placing the call light within reach and washing your hands.

CNA Exam FAQ

Is the CNA Exam Hard?

Most candidates who complete a state-approved training program are well prepared for the CNA exam, but it is not a formality. The written test checks safety rules, infection control, resident rights and basic care, and the skills test is strict about steps like handwashing and checking identity. Regular practice tests and rehearsing each skill aloud make the biggest difference.

Is the CNA Written Exam Hard?

The written exam uses straightforward multiple-choice questions, but many are scenario-based and ask for the safest or best first action. Candidates who struggle usually miss questions on resident rights, communication and infection control rather than on clinical facts, so review those areas with timed practice.

How Many Questions Are on the CNA Certification Exam?

In states that use the NNAAP, the written examination has 70 multiple-choice questions: 60 are scored and 10 are unscored pretest questions, with 2 hours to finish according to the Credentia candidate handbook. States that use a different test vendor set their own question count, so check your state’s candidate handbook.

Is the CNA Test Easy?

It is manageable rather than easy. The content matches what you learn in a state-approved nurse aide program, but you must pass both the written and skills parts, and one missed critical step on the skills test can mean failing that task. Treat it like any licensing exam and practise both parts.

Is the CNA Test Multiple Choice?

The written part is multiple choice: each question has four answer options and one correct answer. NNAAP also offers an oral version where the questions are read aloud, which includes a short reading comprehension section. The skills evaluation is not multiple choice — you perform tasks while an evaluator watches.

How Many Questions Can You Miss on the CNA Written Exam?

There is no single national number, because each state sets its own passing standard for the CNA exam. Your state’s candidate handbook lists the passing score. Our practice test uses a 70% readiness benchmark, and scoring consistently above it is a good sign that you are ready.
