What is a Certified Nursing Assistant (CNA) Exam?

The Certified Nursing Assistant (CNA) exam is a standardized certification test designed to ensure that individuals are fully prepared to perform the essential duties of a nursing assistant. It serves as a critical gatekeeper in the healthcare field, verifying that each candidate possesses both the knowledge and the practical skills necessary to provide high-quality, safe, and compassionate care to patients.

Passing the CNA exam is a mandatory requirement in every U.S. state before you can be listed on your state’s Nurse Aide Registry and legally work as a CNA. The exam helps protect patients by ensuring that only qualified caregivers enter the workforce.

Why is the CNA Exam Important?

Certified Nursing Assistants play a direct, hands-on role in patient care. They help with daily activities such as bathing, dressing, feeding, mobility, toileting, and monitoring vital signs. CNAs are often the first to notice changes in a patient’s condition, making their training and competence critical to maintaining health and safety.

The CNA exam serves to:

• Ensure standardized levels of care across different facilities and states.
• Verify that new CNAs can perform essential tasks confidently and correctly.
• Reinforce ethical standards, patient rights, and the principles of dignified care.

What Does the CNA Exam Include?

The CNA exam is generally divided into two main parts, each designed to test a different but equally important area of your capabilities.

1. Theoretical Knowledge (Written or Oral Test)

This section evaluates your understanding of the concepts, terminology, and protocols required in daily nursing assistant work. Typically administered as a multiple-choice test, it covers topics such as:

• Basic nursing skills: assisting with feeding, bathing, toileting, and mobility
• Patient rights and ethics: respect, dignity, and privacy
• Safety and infection control: preventing accidents and the spread of disease
• Communication and interpersonal skills: interacting effectively with patients and the care team
• Medical terminology and anatomy basics: understanding common conditions and body systems
• Mental health and social needs: supporting patients with cognitive or emotional challenges

Most state exams include anywhere from 60 to 90 multiple-choice questions, typically completed within 90 minutes.

2. Practical Skills (Clinical or Skills Evaluation)

This hands-on portion tests your ability to correctly demonstrate the procedures you’ll perform on the job. Under the observation of a nurse evaluator, you’ll complete a set of randomly selected skills — often five — from a standardized list. These may include:

• Hand hygiene (hand washing)
• Assisting with ambulation using a transfer belt
• Taking and recording vital signs
• Providing catheter care or perineal care
• Feeding a patient who cannot feed themselves
• Changing a patient’s position in bed
• Performing range of motion exercises

Your performance is evaluated on whether you complete all key steps correctly, maintain patient safety, provide privacy, and communicate appropriately. Failing critical steps—like neglecting hand hygiene or forgetting to lock the wheelchair brakes—can result in not passing this portion, even if other skills were done correctly.

What Happens After Passing the CNA Exam?

Once you successfully complete both parts of the CNA exam, you’ll be added to your state’s official Nurse Aide Registry. This means you’re legally recognized as a Certified Nursing Assistant and eligible to work in hospitals, nursing homes, home health, and other care settings. Certification also opens doors to advanced nursing or specialty roles in the future.
