The California Certified Nursing Assistant (CNA) Exam is a mandatory state-level certification test designed to evaluate the competency and readiness of prospective nursing assistants. Administered by testing vendors approved by the California Department of Public Health (CDPH)—most commonly Credentia, D&SDT-Headmaster, or specific Regional Testing Centers—the exam ensures candidates possess the theoretical knowledge and practical hands-on skills required to deliver safe, high-quality patient care. Passing this exam is the final, essential step to being placed on the California Nursing Assistant Registry, which is legally required to practice as a CNA in the state's healthcare facilities.

Exam Format and Passing Score

The California CNA certification exam is divided into two distinct components: a Knowledge (Written/Oral) Exam and a Manual Skills Evaluation. Candidates must successfully pass both sections to earn their certification.

• Written Knowledge Exam
• Format: Multiple-choice
• Number of Questions: 70 questions
• Time Limit: 2 hours (120 minutes)
• Passing Score: Minimum of 70% (you must answer at least 49 questions correctly)
• Manual Skills Evaluation
• Format: Hands-on clinical demonstration in front of a proctor
• Number of Tasks: 5 randomly assigned clinical skills (proper handwashing is universally tested on every exam)
• Time Limit: Typically 30 minutes
• Passing Score: Must pass all 5 skills to achieve a "Satisfactory" overall grade. Failing to perform a highlighted Critical Element Step—a step vital to patient safety or infection control—results in an automatic failure for that specific skill.

Core Exam Topics / Categories

The written portion of the exam assesses candidates across a wide range of essential healthcare and patient-management categories. Primary subjects tested include:

• Basic Nursing Skills: Taking and recording vital signs (blood pressure, pulse, respiration, temperature), measuring height and weight, and recognizing abnormal physical changes.
• Personal Care Skills (ADLs): Safely assisting patients with activities of daily living, including bathing, grooming, dressing, feeding, hydration, and toileting.
• Infection Control: Understanding the chain of infection, demonstrating proper hand hygiene, utilizing personal protective equipment (PPE), and maintaining standard sanitary precautions.
• Safety and Emergency Procedures: Preventing patient falls, using proper body mechanics for lifting and transferring, and responding accurately to medical emergencies, choking, or facility fires.
• Communication and Interpersonal Skills: Effectively interacting with patients, families, and the broader healthcare team, as well as accurate medical charting and reporting.
• Mental Health and Social Service Needs: Providing emotional support, recognizing psychosocial needs, and caring for patients with cognitive impairments, such as dementia or Alzheimer’s disease.
• Resident Rights: Advocating for patient privacy, dignity, independence, confidentiality, and strict protection against abuse, neglect, or exploitation.
