February 13, 2023 · 4 min read

Becoming a certified nursing assistant (CNA) is an excellent way to start a career in the healthcare field. CNAs provide basic care to patients in hospitals, nursing homes, and long-term care facilities, and they play an important role in the healthcare system. If you are interested in becoming a CNA, the following is a guide on how to become one.

Step 1: Research the role of a CNA

Before beginning the certification process, it's important to understand what a CNA does and the responsibilities associated with the role. CNAs work under the supervision of registered nurses (RNs) and licensed practical nurses (LPNs) to provide basic patient care and support services. Their tasks may include bathing, dressing, and grooming patients, monitoring their vital signs, and assisting with mobility and rehabilitation.

Step 2: Meet the eligibility requirements

To become a CNA, you must meet certain eligibility requirements. These may include:

  • Being at least 18 years of age
  • Holding a high school diploma or equivalent
  • Having a clean criminal record
  • Being able to pass a background check
Step 3: Complete a state-approved training program

Next, you'll need to complete a state-approved training program.The specific requirements for training programs vary by state, so it's important to check with your state's nursing board for more information.

The purpose of the training program is to prepare aspiring CNAs with the knowledge and skills needed to provide quality care to patients. During the program, students will learn about the basic principles of nursing, anatomy and physiology, infection control, patient rights and communication, and other topics relevant to the role. In addition to classroom instruction, students will also participate in clinical experiences, where they will have the opportunity to apply what they have learned in a real-world setting.

The length of the training program and the number of clinical hours required will vary by state. Some states require a minimum of 75 hours of training, while others require up to 120 hours. It's important to check with your state's nursing board for the specific requirements in your area.

Step 4: Pass the certification exam

Once you have completed the training program, the next step is to pass the certification exam. The exam is designed to test your knowledge of nursing principles and your ability to perform specific nursing tasks.

The certification exam typically consists of two parts: a written portion and a clinical skills evaluation. The written portion will test your knowledge of nursing concepts, procedures, and patient care. The clinical skills evaluation, on the other hand, will test your ability to perform specific nursing tasks, such as taking vital signs, transferring patients, and providing personal care.

The specific format of the certification exam may vary by state, so it's important to check with your state's nursing board for more information. Once you have passed the exam, you will be a certified nursing assistant and eligible to work in a healthcare setting.

It's important to note that the certification exam can be challenging, but with proper preparation and a commitment to your education, you can be confident in your ability to pass.

Step 5: Register with the state

Once you've passed the certification exam, you'll need to register with your state's nursing board. This typically involves submitting proof of your education and exam results, as well as paying any applicable fees. The registration process may also vary by state, so it's important to check with your state's nursing board for more information.

Step 6: Maintain your certification

To maintain your certification, you'll need to renew it every 2 years and complete continuing education requirements. This may involve taking additional courses, attending seminars, or participating in other professional development activities. The continuing education requirements may also vary by state, so it's important to check with your state's nursing board for more information.


By following these steps and being dedicated to your education and training, you can become a skilled and compassionate CNA and make a difference in the lives of your patients. And remember, the specific requirements for becoming a CNA may vary by state, so it's always a good idea to check with your state's nursing board for the most up-to-date information.
