What the NNAAP written exam actually tests (and what to study)

Most CNA candidates study the wrong things. They buy a textbook, read it cover to cover, and walk into the exam hoping the right facts stick. Then they're surprised when half the questions feel unfamiliar.

It doesn't have to be that way. Credentia, which develops and manages the NNAAP, publishes a content outline that tells you what's tested. Here's how to use it.

How the exam is built

The NNAAP written test has 70 multiple-choice questions, and 10 of them are unscored pretest items, so 60 questions count toward your result. You have up to two hours. If you choose the oral version, you get 60 multiple-choice questions plus 10 reading comprehension questions. Credentia reports results as Pass or Fail only, with no numeric score, and it does not publish a passing percentage, so don't trust any site that quotes one. Your state's candidate handbook is the place to confirm the exact format for your state, because not every state uses the NNAAP.

Credentia's current content outline took effect in October 2024. We haven't verified the percentage weights for each content area, so we don't quote any here. Read the outline itself, and spend more of your time on the hands-on care topics, which you will also need for the skills test.

"

Common mistake: candidates spend weeks on the parts that sound important, like the role of the nurse aide, and skip the practical care content. Cover all of it, and let the outline tell you the proportions.

What's actually on the test

Within each domain, you'll see questions from specific subcategories. Here are the high-yield ones:

• ADLs (bathing, dressing, toileting, feeding, ambulation)
• Infection control (hand hygiene, PPE, isolation precautions)
• Vital signs (temperature ranges, pulse sites, blood pressure)
• Body mechanics (transfer techniques, lift safety)
• Skin integrity (pressure ulcer staging, prevention)
• Communication (resident rights, reporting changes)
• Mental health (dementia, depression, end-of-life care)

The exam is multiple choice. The bigger risk is losing time because you're stuck on unfamiliar topics, so keep moving and come back to the hard ones.

How to study in the right order

A study plan that respects the content outline:

1. Start with physical care and safety — these topics are concrete and carry over to the skills test. Practice with real exam questions, not generic quizzes.
2. Then the role of the nurse aide — communication, documentation, scope of practice. These are easier to absorb once you have the practical context.
3. Psychosocial care last — more conceptual. Worth studying, but practice questions will show you how much time it needs.

For each topic, the same loop: read the material briefly, then answer 20–30 practice questions on it. Reading alone doesn't work. The exam tests recognition and judgment, not recall.

What to skip

Don't waste time on:

• Detailed state-specific regulations. The NNAAP has core content that crosses state lines. State-specific procedures (like California's title 22) are not on the NNAAP written exam. They matter for the clinical skills test in your home state, but not for the multiple-choice.
• Pharmacology beyond basic classifications. You don't need to know drug names or interactions. You need to know why medications might be given, what to observe, and what to report.
• Memorizing long lists. Mnemonics help, but the exam tests application. Practice questions beat flashcards for this kind of material.

Where ExamReady fits

ExamReady CNA generates practice questions organized by topic. When you finish a question, we tell you which topic it tested, so you can spot your weak areas fast.

If you've been studying randomly, that's the most likely reason the practice scores aren't moving. Re-prioritize by topic, start with your weakest areas, and you'll see a real shift.
