CNA Exam Guide. what to expect and how to pass

How the CNA exam is structured

The CNA competency exam is a two-part test. Every state requires it before they'll add you to the Nurse Aide Registry. Most states use the National Nurse Aide Assessment Program (NNAAP) exam, run by Prometric. Some states use Pearson VUE or D&S Diversified Technologies. Your training program will tell you which one applies.

You have to pass both parts to get certified: the written (or oral) knowledge test and the clinical skills evaluation. In most states you can take them on the same day or split them up.

Part 1. the written knowledge test

The written test is 60 to 100 multiple-choice questions, depending on your state. You usually get 90 minutes. Nine content areas show up:

• Physical care skills: ADLs, positioning, mobility assistance, nutrition, hygiene
• Psychosocial care: Emotional support, cultural sensitivity, communication techniques
• Role and responsibility: Scope of practice, delegation, ethical behavior
• Infection control: Hand hygiene, standard precautions, PPE use, isolation protocols
• Safety and emergency procedures: Fall prevention, fire safety, choking response, seizure management
• Data collection and reporting: Vital signs, intake/output, observation and documentation
• Patient rights: Privacy, dignity, informed consent, abuse prevention
• Communication: Nurse-to-aide reporting, care plan interpretation, medical terminology basics
• Legal and ethical issues: HIPAA, advance directives, mandatory reporting

Passing scores vary by state but are usually 70% to 80%. If English isn't your first language, most states offer an oral version of the exam, where the same questions are read aloud by a proctor or played over audio.

Part 2. the clinical skills test

The skills evaluation is a hands-on test. You demonstrate 3 to 5 randomly selected skills in front of a nurse evaluator. Each skill is scored against a checklist. Miss a critical step and you fail that skill.

The skills that come up the most:

• Handwashing. Almost always tested. It's the foundation of infection control.
• Taking and recording vital signs. Blood pressure, pulse, respiration, temperature.
• Positioning and turning. Moving a patient in bed safely, using proper body mechanics.
• Range of motion exercises. Passive ROM for upper and lower extremities.
• Perineal care. Keeping dignity intact during intimate hygiene.
• Dressing a patient with a weak side. The "affected side first" rule.
• Measuring and recording intake and output.
• Transferring a patient from bed to wheelchair.

CNA exam pass rates

National first-attempt pass rates sit around 85% to 90% on the written portion and 80% to 85% on clinical skills. Most people who finish an accredited program pass the first time.

If you don't pass, most states let you retake each portion up to three times. After that you may need more training hours. Retake fees are typically $30 to $60 per portion.

How to study

1. Use practice tests daily. Free practice exams from CNA Plus Academy and Union Test Prep mirror the NNAAP format. Take at least one full-length practice test a week.
2. Practice skills with a partner. Grab a classmate or a family member and drill each skill until you can do it from memory, without the checklist.
3. Focus on critical steps. Every clinical skill has "critical element" steps. Miss one, you fail that skill. Know them cold.
4. Study infection control. Handwashing, gloving, and standard precautions show up on both the written and clinical tests. Highest-yield topic.
5. Review patient rights. Dignity, privacy, and informed consent questions are common and easy to trip on. Know the legal basics.
6. Make flashcards for vital sign ranges. Normal ranges for BP, pulse, respiration, and temperature come up a lot. Memorize them plus when to report abnormalities.

What to bring on exam day

• Two forms of ID. One has to be a government-issued photo ID (driver's license or passport). The second can be a Social Security card, school ID, or a signed credit card.
• Confirmation letter or scheduling email.
• Watch with a second hand. For counting pulse and respirations. No smart watches.
• Closed-toe shoes you can stand in. You'll be on your feet for the clinical portion.
• Scrubs or professional attire. Most testing sites require scrubs for the clinical test.
• Stethoscope and blood pressure cuff. Some sites provide equipment. Bring your own as backup.

Get there at least 30 minutes early. Late arrivals are usually turned away and forfeit the exam fee. Turn your phone off before you walk into the testing room.

After you pass

Once you pass both portions, your name lands on your state's Nurse Aide Registry, usually within 2 to 4 weeks. You get a CNA certification number that employers can verify. Most certifications renew every two years, and renewal requires proof of employment (typically 8 hours of paid work) plus continuing education.

Once you're on the registry, you're ready to work. A lot of facilities have open shifts, and demand for CNAs outpaces supply in most states. Submit your profile through CareGigs to get matched with facilities hiring newly certified CNAs.
