(verify current requirements with your state registry before test day, as some details vary by source.)
The Illinois CNA written exam covers real clinical knowledge, from infection control to residents' rights under federal OBRA 1987 protections. Practising realistic multiple-choice questions with full explanations builds the recall speed you need, especially for scenario-based questions that test judgment, not just memorization.

85 questions, administered by Southern Illinois University Carbondale (SIUC) - Illinois Nurse Aide Testing. Certification renews every 2 years (24 months).
About the CNA (Nursing Assistant), nationwide
The CNA written competency exam is administered state by state, most commonly through Credentia (NNAAP), Prometric, or D&S/Headmaster, but the underlying content domains, basic nursing skills, personal care skills, residents' rights, and infection control, are set nationally and tested everywhere.
Basic Nursing Skills and Personal Care Skills carry the most weight combined
Vital signs, positioning and transfers, and activities of daily living make up the largest share of most state exams. These are also the skills tested again on the hands-on skills portion, so mastering them pays off twice.
Residents' Rights questions have a clear, correct pattern
The right answer almost always favors dignity, privacy, choice, and informed consent. When in doubt between two options, choose the one that respects the resident's autonomy.
Know your state's specific vendor and renewal requirements
Testing vendor, question count, and renewal periods vary by state, some renew every 2 years, others require registry renewal on a different cycle. Confirm your state's specific process before test day.
