Healthcare is one of the fastest-growing industries in the United States, and California is no exception. If you have a passion for helping others and are wondering how to become a nursing assistant, you are looking at a career path with high demand, excellent job stability, and immense personal reward. 

Whether you refer to the role as a CNA or a nurse aide, these frontline healthcare professionals are the backbone of patient care in hospitals, long-term care facilities, and clinics. If your goal is to become a CNA in California, the path is clearly defined by the California Department of Public Health (CDPH). 

Step 1: Meet the Initial CDPH Requirements

Before you can enroll in a program and begin your coursework, the state requires all prospective nursing assistants to meet a few baseline criteria. To be eligible, you must:

  • Be at least 16 years old.
  • Have a valid Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN).
  • Pass a physical health screening and provide an up-to-date immunization record.
  • Pass a criminal background check via the Live Scan fingerprinting process. The CDPH requires this background clearance before you can have direct patient contact.

Step 2: Complete a State Approved Nursing Assistant Training Program

The most critical step in your journey is your education. You cannot simply challenge the state exam on your own; you must enroll in and complete a state approved nursing assistant training program.

According to CDPH regulations, your Nursing Assistant Training Program must consist of at least 160 hours of total instruction. This is broken down into two distinct parts:

  • Theory and Classroom Instruction: A minimum of 60 hours of classroom learning. Your CNA classes will cover essential topics like infection control, vital signs, anatomy, basic nursing skills, and patient communication.
  • Hands-on Practice: A minimum of 100 hours of supervised clinical training in a real healthcare setting, such as a skilled nursing facility.

Looking for a curriculum you can trust? The certified nursing assistant training program at Medical Allied Career Center is designed to exceed these state standards, fully preparing you for both your exams and your future daily duties.

Step 3: Pass the California CNA Certification Exam

Once you successfully graduate from your program, your next step is passing the state Competency Evaluation Examination. In California, this test is administered by regional testing vendors and consists of two parts:

  • The Written (or Oral) Exam: A multiple-choice test consisting of 70 questions covering patient care, ethics, and medical terminology. You have two hours to complete it.
  • The Clinical Skills Evaluation: You will be asked to physically demonstrate 3 to 5 randomly selected nursing skills (such as measuring blood pressure, proper handwashing, or assisting a patient with feeding) in front of an evaluator.

Step 4: Submit Your Application for Certification

After passing both portions of the state exam, you will submit your final documentation to the CDPH Healthcare Professional Certification and Training Section (HPCTS). You can do this online through the CDPH OASYS system or via mail. You will need to provide:

Once the CDPH reviews and approves your application, your official certificate will be issued. Congratulations—you are officially a Certified Nursing Assistant! Now, you just have to renew your CNA certification every two years.

Launch Your Career with the Right CNA Training Program in California

Becoming a CNA is an excellent entry point into the medical field. Many nurses use their experience as a nurse aide as a stepping stone toward becoming a Licensed Vocational Nurse (LVN) or Registered Nurse (RN).

The quality of your education determines how prepared you are for the floor. If you are ready to become a CNA in California, choose a facility that offers expert instructors, comprehensive clinical training, and a supportive learning environment.
