CNA Competency Exam: Your Complete 2026 Guide

The CNA competency exam is the final step to becoming a certified nursing assistant in the United States. It measures whether you have the knowledge and hands-on skills to provide safe, compassionate care. Whether you're just starting your training or preparing to retake a section, understanding the exam's structure and expectations can make all the difference.

What Is the CNA Competency Exam?

The competency exam is a standardized evaluation required by federal law for nurse aides working in Medicare- or Medicaid-certified nursing facilities. It consists of two parts: a written (or oral) knowledge test and a hands-on skills demonstration. You must pass both to be placed on your state's Nurse Aide Registry.

Each state contracts with a testing provider, such as Prometric or Pearson VUE, to administer the exam. While the format may vary slightly, the core content is consistent nationwide and based on the Centers for Medicare & Medicaid Services (CMS) guidelines.

Written Exam: What to Expect

The written portion typically includes 50 to 70 multiple-choice questions. You'll have about 90 minutes to complete it. Questions cover topics like:

• Basic nursing skills (vital signs, infection control, positioning)
• Safety and emergency procedures
• Communication and resident rights
• Personal care and activities of daily living
• Mental health and psychosocial needs

Some states offer an oral version for candidates who have difficulty reading. If English is your second language, check with your state board about accommodations.

How to Prepare for the Written Exam

Start by reviewing your textbook and class notes. Then, take practice tests to identify weak areas. Our CNA written exam practice questions mirror the real test's style and difficulty, helping you build confidence and speed.

Focus on understanding concepts rather than memorizing. For example, know why hand hygiene is crucial before and after every resident contact, not just that it's a step.

Skills Exam: Hands-On Demonstration

The skills test requires you to perform a set of nurse aide tasks while an evaluator observes. You'll be given a scenario and asked to complete specific skills, usually three to five, within a time limit (often 30–40 minutes total).

Common skills include:

• Handwashing
• Measuring blood pressure
• Assisting with ambulation
• Providing mouth care
• Transferring a resident

You must perform each step correctly, in the right order, and maintain a safe environment. Critical steps—like locking wheelchair brakes or checking for a pulse, are automatic failures if missed.

Tips for Mastering the Skills Exam

Practice each skill until it becomes second nature. Use a checklist to ensure you don't skip steps. During the exam, verbalize what you're doing and why; this shows the evaluator you understand the rationale. Also, remember to introduce yourself, explain the procedure to the resident, and provide privacy.

Scoring and Passing

Each section is scored separately. The written exam typically requires a score of 70% or higher to pass, though some states set the bar at 75%. The skills exam is pass/fail; you must perform all critical steps correctly and complete the skill within the time limit.

If you fail one part, you can usually retake just that section. Most states allow at least two retakes within a certain timeframe. Check your state's rules for specifics.

How to Register for the Exam

Registration is usually done online through your state's testing provider. You'll need to provide proof of completing a state-approved training program (typically 75–120 hours). Some states require a criminal background check before you can sit for the exam.

Fees vary by state but generally range from $100 to $200 for both sections. Financial assistance may be available through your employer or workforce development programs.

Test Day Tips

• Arrive early with your required ID and admission letter.
• Dress professionally and wear comfortable shoes.
• Listen carefully to instructions and ask for clarification if needed.
• Stay calm and breathe. You've trained for this.

After You Pass

Once you pass both sections, your name will be added to your state's Nurse Aide Registry. You can then begin working as a CNA. Remember to renew your certification before it expires, most states require renewal every two years, along with proof of continuing education or work hours.
