How to Pass the CNA Exam on Your First Try (2026 Guide)

The CNA exam — formally known as the NNAAP (Nurse Aide Assessment Program) — is the licensing exam required to become a Certified Nursing Assistant in the United States. It has two parts: a written (or oral) knowledge test and a clinical skills evaluation. This guide focuses on the written test. The written exam consists of 70 multiple-choice questions. You have 2 hours to complete it. To pass, you need to score at least 70% — correctly answering at least 49 of the 70 questions.

The NNAAP written exam covers six content areas, each weighted differently: • Physical Care Skills — 45% of the exam. This is the largest section and covers personal hygiene, bathing, grooming, feeding, elimination care, positioning, transfers, and mobility. • Safety & Emergency Procedures — 14%. Fire safety (RACE protocol), fall prevention, restraint alternatives, and emergency response. • Infection Control — 14%. Handwashing technique, standard precautions, PPE donning and doffing order, and isolation precautions. • Resident Rights — 11%. OBRA regulations, privacy, dignity, the right to refuse care, and recognizing and reporting abuse and neglect. • Psychosocial Care Skills — 8%. Therapeutic communication, dementia and depression care, cultural sensitivity, and end-of-life support. • Role of the Nurse Aide — 8%. Scope of practice, chain of command, documentation, and legal and ethical responsibilities. Because Physical Care Skills makes up nearly half the exam, it deserves the most study time.

Most students who pass on their first attempt spend 2–4 weeks preparing consistently. Here is a realistic study schedule: • Week 1: Physical Care Skills. Spend time on bathing, oral care, positioning and transfers, and elimination care. These topics alone can account for 30+ questions. • Week 2: Infection Control and Safety. Master hand hygiene, PPE order, RACE, and fall prevention. These are heavily tested and very specific. • Week 3: Resident Rights, Psychosocial Care, and Role of the Nurse Aide. These sections are smaller but require careful reading — the answers are nuanced. • Week 4 (if time allows): Full practice tests. Simulate real exam conditions. Review every question you get wrong and read the explanation.

Students who fail the CNA exam on their first attempt typically make one of these mistakes: 1. Skipping Physical Care Skills. Because the questions seem straightforward, students underestimate how specific the exam gets. The correct order of steps matters. 2. Memorizing answers instead of understanding concepts. The exam changes question wording. If you understand why the correct answer is right, you can handle any phrasing. 3. Not reviewing answer explanations. Getting a practice question right does not mean you know why it is right. Always read the explanation. 4. Running out of time. 2 hours for 70 questions is about 1 minute and 43 seconds per question. Practice pacing. Do not spend more than 3 minutes on any single question — flag it and come back. 5. Overthinking. CNA exam questions are written to test what a nurse aide should do first, not what a nurse or doctor would do. When in doubt, choose the answer that prioritizes safety and resident dignity.

Practice tests are the single most effective study tool for the NNAAP exam. Here is how to use them: • Take a full 70-question test in one sitting before you start studying. This diagnostic helps you see which topics you already understand and which need the most work. • After each test, review every question — not just the ones you got wrong. Understanding why a correct answer is correct is as important as knowing why wrong answers are wrong. • Do not memorize questions. The real exam will not use the same wording. Focus on the underlying concept. • Aim for 80% or higher on practice tests before you sit for the real exam. You want a buffer above the 70% passing threshold. CertPrepAcademy.com offers a free 70-question practice test that mirrors the real NNAAP format — same number of questions, same topic distribution, with detailed explanations for every answer.

The CNA written exam (NNAAP) has 70 multiple-choice questions. Of those 70, 10 are unscored pilot questions used to develop future exams — you will not be told which ones, so answer every question as if it counts. The 60 scored questions determine your pass/fail result. You have 2 hours to complete the exam.

Nationally, approximately 75–80% of candidates pass the CNA written exam on their first attempt. The clinical skills test has a lower first-attempt pass rate — closer to 65–70% in most states. This means about 1 in 4 candidates does not pass the written exam on the first try. Most candidates who fail once pass on their second attempt when they study from their score report and focus on weak topics rather than starting over from scratch.

Most candidates who pass on their first attempt study consistently for 2–4 weeks after completing their training program. Candidates who cram the night before or study over a single weekend have significantly lower pass rates. Quality of study matters more than total hours: 2 weeks of focused practice test review with answer explanations outperforms 4 weeks of re-reading textbook chapters.

No. Federal law requires all candidates to complete a state-approved CNA training program before sitting for the licensing exam. The federal minimum is 75 hours of training, including at least 16 hours of supervised clinical practice, though most states require 100–175 hours. A small number of states allow nurses or nursing students with equivalent clinical experience to challenge the exam directly, but the general public must complete an approved program first.

Most states use the NNAAP (Nurse Aide Assessment Program) format, covering the same six content areas with the same 70-question structure and 70% passing score. However, different testing vendors administer the exam depending on your state — Prometric, Credentia, HDmaster, and others — and a few states use their own exam format entirely. The core content, passing standard, and exam length are consistent across NNAAP states.

Failing the first time does not disqualify you. Most states allow up to 3 retake attempts within a 24-month window from completing your training program. Your score report will break down your performance by content area — use it to identify weak topics and study those specifically before rescheduling. Most candidates who fail once pass on their second attempt when they target their weak areas rather than re-studying everything.
