What Is the NNAAP Exam?
The NNAAP (Nurse Aide Assessment Program) is the standardized competency exam required to become a certified nursing assistant in most U.S. states. You take it after completing a state-approved CNA training program — typically 75 to 150 hours depending on where you live.
The exam has two separate parts, and both must be passed to be listed on your state’s nurse aide registry.
Written (or oral) exam: A multiple-choice test taken at a testing center. The number of questions and time limit varies by state and testing vendor — typically 60–70 questions with 90–120 minutes to complete. Some questions are unscored pilot items; you won’t know which. The passing standard is 70% in most states.
Clinical skills exam: You perform 5 randomly selected nursing skills in front of a trained evaluator. Each skill is scored on a standardized checklist. Common tested skills include hand washing, vital signs measurement, bed bath, transfer assistance, and range of motion exercises.
If you fail one part, you typically have multiple attempts to retake it without repeating your full training program. Check your state’s rules for specific attempt limits and waiting periods.
The practice tests on this page cover the written exam only. The questions apply regardless of which testing company your state uses — Credentia, Prometric, and Headmaster all test the same content.
NNAAP Exam Domains
The NNAAP written exam is organized into three domains. The weightings below show how much of the 60 scored questions each domain represents — knowing them helps you allocate your study time.
| Domain | Exam Weight | What It Covers |
|---|---|---|
| Domain I: Physical Care Skills | 64% | Activities of daily living, bathing, grooming, oral care, feeding, skin care, catheter care, infection control, vital signs, safety, technical procedures, and restorative care |
| Domain II: Psychosocial Care Skills | 10% | Emotional and mental health support, dementia care, grief stages, spiritual and cultural needs, social service needs, and abuse and neglect recognition |
| Domain III: Role of the Nurse Aide | 26% | Residents’ rights, privacy and confidentiality, legal and ethical conduct, communication with the healthcare team, and the CNA’s scope of practice |
Questions on the NNAAP follow a consistent format: a scenario or situation, then four answer choices. There is always one best answer. Questions are practical rather than purely factual — they ask what you should do in a given situation, not just what you know.
How to Use These Practice Tests
Start with the section that concerns you most. Take the topic-specific test, then read every explanation — including for questions you answered correctly. The explanations provide context that helps you apply the same reasoning to new questions.
If your score on a section is below 70%, review the relevant topics, then retake. You’ll see a different mix of questions on each attempt.
Once you’re consistently passing the domain tests, take the full mixed practice test. It simulates the real exam’s variety and is the best final check before your test date.
