- First-attempt pass rates for the NNAAP vary by state and testing vendor, but a meaningful percentage of candidates do not pass on their first try.
- The skills (clinical) portion is where the most candidates fail, not the written test.
- Repeat test-takers face stricter timelines and additional fees, making first-attempt success critical.
- Targeted domain-specific practice - not generic study habits - is the single strongest predictor of passing.
Why Pass Rates Matter for NNAAP Candidates
When you are preparing to become a certified nurse aide, pass rate data is not just a curiosity - it is a planning tool. Understanding where candidates fail helps you allocate study time intelligently, set realistic expectations, and avoid the costly cycle of retakes. The NNAAP certification is the most widely administered nurse aide competency evaluation in the United States, and its pass rate trends carry real consequences for your career timeline and wallet.
Unlike many professional exams, the NNAAP has two distinct components that are scored and reported separately: a written (or oral) knowledge test and a hands-on clinical skills evaluation. That structure means a candidate can pass one section and fail the other, creating a complicated picture when interpreting aggregate pass rate data. Most published figures blend both components together, which can obscure exactly where candidates are struggling.
If you are just beginning to explore the credential itself, start with our overview of What Is NNAAP? before diving into the data. For candidates already familiar with the exam structure, read on.
What the Data Actually Shows
Pass rate data for the NNAAP is collected at the state level by testing vendors - primarily Pearson VUE and NCSBN's affiliate programs - and is not always published in a centralized, publicly accessible format. State nurse aide registries and departments of health periodically release summary statistics, but the data is inconsistent across jurisdictions. What we can say with confidence, based on patterns across states that do publish figures:
- First-attempt pass rates vary significantly by state, often reflecting the quality of training programs, the demographics of test-takers, and whether testing sites are urban or rural.
- The written portion consistently sees higher pass rates than the skills portion among candidates who sit both on the same day.
- Retake rates are not trivial. A substantial number of candidates who fail one component must return and pay additional fees, creating both financial pressure and scheduling delays.
- Program-type matters. Candidates who completed state-approved nurse aide training programs (NATPs) outperform self-study or challenge candidates across nearly every state that tracks the distinction.
Because NNAAP pass rates are not reported in a single national dataset with precise percentages, we will not invent numbers here. What the literature and state registry data consistently confirm is qualitative: preparation quality, not test-taking luck, is the dominant variable. That is an actionable insight regardless of which specific percentage applies in your state.
Written vs. Skills: Where Candidates Struggle Most
The Written Examination
The written portion of the NNAAP tests cognitive knowledge across the exam's content domains. Questions are multiple-choice, and the test is designed to assess whether a candidate can recognize safe, appropriate nurse aide practice across a range of clinical and interpersonal scenarios. Candidates who have gone through structured classroom instruction generally feel more confident here, though tricky question phrasing and scenario-based items catch many off guard.
Understanding exactly what the written exam covers - and how questions are worded - is the subject of our detailed NNAAP Exam Domains 2026: Complete Guide to All 3 Content Areas. Reviewing that guide before you analyze your practice test results will help you connect content gaps to specific domains rather than studying blindly.
The Skills Evaluation
The clinical skills portion is where the data consistently shows higher failure rates. Candidates are observed performing a set of randomly assigned nurse aide skills by a trained evaluator. Each skill has a checklist of critical steps, and missing even one critical step can result in automatic failure of that skill - even if everything else was performed correctly.
This is a fundamentally different type of failure from getting a multiple-choice question wrong. It requires a different type of preparation: repeated, observed practice with a partner who holds the actual evaluation checklist, not just reading about the skill or watching a video. Candidates who arrive at the skills station having only practiced alone in a bedroom consistently underperform those who have rehearsed in front of an evaluator or fellow student.
Factors That Influence Your Odds
Several variables move the needle on pass rates that candidates can actually control:
| Factor | Impact on Pass Rate | What You Can Do |
|---|---|---|
| Completion of a state-approved training program | Strongly positive | Enroll in an NATP if possible; do not self-study in isolation |
| Practice test volume before exam day | Moderately to strongly positive | Use format-accurate NNAAP practice tests repeatedly |
| Skills rehearsal with observer | Strongly positive for skills component | Practice every skill with a partner holding the checklist |
| Time since training completion | Negative (longer gap = lower pass rate) | Schedule your exam within weeks of completing training |
| First attempt vs. retake | First attempts pass at higher rates | Invest heavily in preparation before your first sitting |
| Test anxiety and fatigue | Moderately negative | Simulate exam conditions during practice |

Domain-by-Domain Risk Assessment
While the NNAAP's exact domain names and content weightings are defined by each state's testing program, the exam consistently organizes content around three major categories. Understanding which domain areas generate the most incorrect answers helps you prioritize.
Domain 1: Physical Care Skills
This domain covers direct hands-on care - activities of daily living, mobility, hygiene, nutrition, and elimination. It is the most heavily weighted domain on most state versions of the NNAAP and also the domain most directly tested in the skills evaluation.
- Candidates who struggle here often have gaps in infection control procedures - especially hand hygiene timing
- Proper body mechanics and positioning questions trip up candidates who memorized procedures without understanding the reasoning
- Oral care, bathing, and perineal care skills have critical steps that are frequently missed under observation
Domain 2: Psychosocial Care Skills
This domain tests candidates' understanding of residents' emotional, social, and mental health needs - including communication, dignity, rights, and responses to behavioral changes. Written exam questions in this domain are often scenario-based and require candidates to identify the most appropriate response rather than a factual answer.
- Questions about resident rights and the nurse aide's legal obligations are common - and commonly missed
- Scenarios involving confused or agitated residents require candidates to understand de-escalation and person-centered care principles
- End-of-life and comfort care scenarios appear on many state versions of the exam
Domain 3: Role of the Nurse Aide
This domain covers the nurse aide's professional responsibilities, communication within the healthcare team, safety and emergency procedures, and legal/ethical obligations. It is frequently the domain where candidates feel most confident - and also where overconfidence leads to careless errors.
- Reporting and documentation questions are based on specific protocols - vague answers are scored wrong
- Abuse recognition and mandatory reporting requirements are high-priority topics in nearly every state
- HIPAA and resident confidentiality scenarios are increasingly common in updated exam versions

Repeat Test-Taker Patterns
Candidates who fail one or both components of the NNAAP face a structured retake process, and the data on retakers is consistent: pass rates on second and third attempts are lower than on first attempts. This is counterintuitive to many candidates who assume that having already seen the test gives them an advantage. Several factors explain this pattern:
- Increased anxiety. Knowing you have already failed once measurably increases test-day stress, which impairs performance - particularly on the skills evaluation where physical composure matters.
- Inadequate gap analysis. Most repeat test-takers study more after a failure, but not differently. They review the same material using the same methods, without identifying which specific domain gaps or critical steps caused the failure.
- Time pressure. State regulations typically limit the number of retake attempts within a fixed window. Candidates who run out of attempts must restart their training program entirely - a significant time and cost consequence.
- Diminishing familiarity with training content. The longer the gap between training completion and exam, the harder it becomes to recall clinical procedures with the precision the skills evaluation requires.
The takeaway is not that retakes are impossible to pass - many candidates do succeed on a second attempt. The takeaway is that treating your first attempt as a dry run is a statistically risky strategy with real financial and timeline consequences.
How Preparation Shifts Your Odds
Given what the pass rate data reveals, the most effective preparation approach for the NNAAP is not generic - it is domain-targeted, format-specific, and split between written and clinical practice tracks. Here is how to structure the final weeks before your exam:
Baseline Assessment + Domain 1 Focus
- Take a full-length practice test to identify your weakest domain areas before studying anything
- Begin skills rehearsal for Physical Care procedures - these require the most repetition to automate
- Review hand hygiene and infection control protocols in detail; these generate critical step failures
Domains 2 & 3 + Skills Expansion
- Work through scenario-based Psychosocial Care questions; practice explaining your reasoning aloud
- Review mandatory reporting, abuse recognition, and HIPAA for Domain 3
- Add observed skills practice with a partner holding the official checklist for every skill
Simulated Exam Conditions + Gap Closure
- Take two to three timed, full-length practice tests under realistic conditions - no phone, no pauses
- Perform complete skills run-throughs from start to finish, simulating evaluator observation pressure
- Target only the domain areas still showing errors; do not re-study material you already know
This structure prioritizes Domain 1 in Week 1 because it has both the highest exam weight and the most critical-step failure risk in the skills evaluation. Domains 2 and 3 receive concentrated attention in Week 2, when the foundation of physical care knowledge is already in place. Week 3 is entirely about simulation and gap closure - not new content.

Frequently Asked Questions
No. Pass rate data for the NNAAP is collected and published at the state level by individual testing programs and state nurse aide registries. There is no centralized national database that aggregates first-attempt or overall pass rates across all states. Check your state's health department or nurse aide registry for any published statistics specific to your jurisdiction.
Across states that report component-level data, the clinical skills evaluation consistently shows higher failure rates than the written test. The skills portion uses strict critical-step checklists, and a single missed step on a critical action can result in automatic failure of that skill. Most candidates underestimate how much observed, checklist-based practice is required to pass consistently.
Retake limits are set by each state and vary. Most states allow three total attempts within a defined period (commonly 24 months from training completion) before requiring a candidate to repeat their nurse aide training program. Because retake fees apply to each attempt and pass rates on repeat sittings tend to be lower, investing heavily in first-attempt preparation is strongly advisable.
Yes, consistently. Candidates who complete state-approved nurse aide training programs outperform challenge candidates and self-study candidates on both the written and skills components across the states that track this distinction. Formal programs provide structured skills labs, observed practice, and instructor feedback - the three inputs most directly tied to skills evaluation success.
Format-accurate practice tests improve pass rates by familiarizing candidates with question style, building time management habits, and - most importantly - identifying domain-specific knowledge gaps before exam day rather than on it. Generic CNA review tools are less effective because they do not mirror the NNAAP's specific question structure and domain weighting. Use NNAAP-specific practice questions to get the most accurate pre-exam diagnostic available.
