California is one of the most active healthcare markets in the country, and the demand for certified nursing assistants across the state reflects that. From major hospital systems in Los Angeles and San Francisco to elder care communities in Sacramento and San Diego, CNAs play a vital role in daily patient care across California.
If you’re ready to start your caregiving career, this guide covers everything you need to know about becoming a CNA in California the requirements, the training process, the exam, and what you can expect to earn.
A certified nursing assistant provides hands-on, direct care to patients and residents in healthcare settings. In California, CNAs work in skilled nursing facilities, hospitals, assisted living communities, and home health environments.
Core responsibilities include assisting with personal hygiene and daily living activities, monitoring vital signs, supporting patient mobility, providing emotional support, and communicating observations to supervising nurses. CNAs in California operate under the supervision of licensed vocational nurses (LVNs) or registered nurses (RNs).
California’s CNA certification process is regulated by the California Department of Public Health (CDPH). Here are the key requirements:
Age: Applicants must generally be at least 18 years old. Some exceptions may apply for students enrolled in high school vocational programs.
Background check: A criminal background check is required. Certain convictions may affect your eligibility. CDPH evaluates applications on a case-by-case basis.
Health clearance: Many training programs and employers require a physical exam, TB test, and up-to-date immunizations prior to beginning clinical hours.
Training program completion: You must complete a CDPH-approved nursing assistant training program before sitting for the state certification exam.
California requires a minimum of 150 hours of combined instruction and clinical training, which exceeds the federal minimum. Approved programs are offered through community colleges, vocational schools, and some skilled nursing facilities.
Training covers anatomy and physiology, infection control, patient rights, safety procedures, communication, and hands-on clinical skills. While enrolling in a formal program is required for the clinical hours, you can strengthen your foundational knowledge beforehand with NCOOA’s CNA exam prep course.
The California CNA exam is administered by Prometric and consists of two parts:

Upon passing your exam, you are added to the California Nurse Aide Registry, maintained by CDPH. Employers access this registry to verify your current certification status. Keeping your contact information up to date on the registry is your responsibility.
California CNA certifications are valid for two years. Renewal requires proof of at least eight hours of paid employment as a nursing assistant during your certification period, along with the completion of required in-service training as determined by your employer.
