Certified Nursing Assistant Exam
The state-approved Certified Nursing Assistant (CNA) exam is a crucial step in becoming a certified nursing assistant. The exam is designed to evaluate the candidate’s knowledge, skills, and abilities in providing care to patients as a nursing assistant. While the specific requirements and processes may vary from state to state, here’s an overview of what you need to know about the CNA exam:

Exam Structure
The specific requirements, format, and content of the exam may vary slightly from state to state, but generally, the exam consists of two parts: a written (or oral) test and a clinical skills evaluation.
The CNA exam typically consists of two parts – a written (or oral) test and a clinical skills evaluation. The written test is usually composed of multiple-choice questions, while the clinical skills evaluation involves demonstrating nursing assistant tasks under the supervision of a trained evaluator.

Written Test
Written (or oral) test: The written portion of the CNA exam typically consists of multiple-choice questions covering a range of topics, including:
Basic nursing skills (e.g., positioning, transferring, and ambulating patients)
Infection control and safety measures
Communication and interpersonal skills
Nutrition and hydration
Vital signs and body measurements
Anatomy and physiology
Care for patients with specific needs (e.g., dementia, mental health issues)
Patients’ rights and legal issues
Some states may offer the written test in an oral format for candidates who have difficulty reading English or have a documented disability.
Clinical skills evaluation
The skills portion of the CNA exam requires candidates to demonstrate their competency in various nursing assistant tasks under the supervision of a registered nurse or licensed practical nurse. A candidate is usually asked to perform a specific number of skills (e.g., 5 skills) chosen at random from a predefined list, which may include:
- Hand hygiene
- Putting on and removing personal protective equipment (PPE)
- Measuring and recording vital signs (e.g., blood pressure, temperature, pulse, respiration)
- Transferring, repositioning, and ambulating patients
- Making an occupied bed
- Providing oral care and grooming assistance
- Feeding and providing hydration to patients
- Assisting with toileting and incontinence care

Exam preparation
To prepare for the CNA exam, it’s essential to review the material covered in your state-approved training program. Utilize study guides, practice exams, and other resources to reinforce your understanding of the material. Some states or training programs may also offer review courses or exam prep materials to help you prepare for the exam.
Registration and Scheduling
To take the CNA exam, you will need to register and schedule your test through your state’s designated testing agency. This may involve submitting an application, providing proof of completion of the training program, and paying the exam fee.
Exam Day
On the day of the exam, arrive early and bring any required identification and documentation. For the clinical skills evaluation, wear appropriate attire, such as scrubs, and comfortable closed-toe shoes.
Exam results
After completing the CNA exam, you will receive your results, typically within a few weeks. The timeframe and method for receiving your results will depend on your state’s testing agency. If you pass both parts of the exam, you will become certified and listed on your state’s nurse aide registry.

Retakes
If a candidate does not pass the CNA exam on the first attempt, most states allow for retakes. However, the rules and guidelines regarding retakes can vary by state. Generally, the following points apply to retaking the CNA exam:
- Number of attempts: Candidates are usually allowed a specific number of attempts (e.g., three) to pass the CNA exam within a certain time frame (e.g., 12 months) after completing their training program.
- Retaking a specific portion: If a candidate passes one part of the exam (either the written/oral test or the clinical skills evaluation) but fails the other, they typically only need to retake the portion they did not pass.
- Waiting period: There may be a mandatory waiting period between attempts, usually a few weeks or a month, depending on the state’s guidelines.
- Exam fees: Candidates may be required to pay the exam fee again for each retake. The cost can vary by state and testing agency.
- Reapplication: Candidates must follow the reapplication process for retakes, which might involve submitting a new application, providing documentation, and scheduling the exam.
- Additional training: If a candidate exhausts the allowed number of attempts without passing the exam, they may be required to retake the CNA training program or complete additional training before being allowed to attempt the exam again.
Renewal
Certified Nursing Assistant (CNA) certification typically needs to be renewed every two years, although the exact renewal period may vary depending on the state. The renewal process ensures that CNAs maintain their competency and stay updated on the latest best practices in their field. The following steps outline the general process for CNA renewal:
- Fulfill continuing education requirements: Most states require CNAs to complete a specific number of continuing education units (CEUs) or in-service training hours within their renewal period. The required number of CEUs or hours can vary by state, but generally ranges from 12 to 48 hours. These courses cover various topics, including new developments in patient care, infection control, and communication skills.
- Verify employment as a CNA: Many states require proof of employment as a nursing assistant during the renewal period. This usually means providing documentation that you have worked as a CNA for a certain number of hours (e.g., 8 hours) within the previous 24 months. The specific requirements may vary by state.
- Complete a renewal application: To renew your CNA certification, you will need to complete a renewal application provided by your state’s nurse aide registry or licensing board. This application typically requires you to provide personal information, employment details, and documentation of completed CEUs or in-service training.
- Submit renewal fees: Some states require CNAs to pay a renewal fee when submitting their renewal application. The fee may vary depending on the state and your specific circumstances.
- Maintain an active status on the nurse aide registry: Upon successful completion of the renewal process, your CNA certification will be updated, and you will maintain an active status on your state’s nurse aide registry.
- Background check: Some states may require a new background check during the renewal process, especially if you have moved or if there have been any changes in your criminal history since your initial certification.
It is crucial to consult your state’s specific requirements for CNA renewal, as there may be slight variations in the process, required documentation, and fees. Staying informed about renewal deadlines and requirements can help ensure that you maintain an active certification and avoid potential lapses in your ability to work as a CNA.
