Enrollment open: 2,867 questions, written to the 2024 NNAAP content outline and independently checked. Enroll today and start with free sample questions.
CNA certification is run by each state, so there is no single national CNA exam — but the written exam most candidates meet is the NNAAP, administered by Credentia: 70 multiple-choice questions built on the 2024 content outline, taken alongside a separate hands-on skills evaluation. PassProfessor’s CNA program gives you 2,867 original practice questions for the written exam — a 1,995-question national core on that outline, plus state-variant sets for California, Texas, Florida, New York, Ohio, Kentucky, and North Carolina — with an explanation on every question and fresh, blueprint-weighted practice exams every time you sit one. This program prepares you for the written (knowledge) exam only; it does not rehearse the hands-on skills evaluation, and your state registry’s own rules always govern your certification.
What’s included
A national core built on the 2024 NNAAP outline. The NNAAP written exam weights its three domains heavily toward hands-on care knowledge: Physical Care Skills at 64%, Role of the Nurse Aide at 26%, and Psychosocial Care Skills at 10%. Our 1,995-question core follows that same shape — 1,277 questions on physical care, 518 on the role of the nurse aide, and 200 on psychosocial care — so the time you spend practicing lands in the same proportions as the exam you will sit.
State-variant sets for seven states. CNA certification is state-run, and states add their own emphases, terminology, and registry rules on top of the shared national content. Alongside the core, the program includes 872 state-variant questions written for candidates testing in California, Texas, Florida, New York, Ohio, Kentucky, and North Carolina. Candidates in other states practice on the full national core, which follows the outline used by the most widely used written exam in the country.
An explanation on every question. Every one of the 2,867 questions explains why the correct answer is right and why the tempting alternatives are wrong, in plain language. The explanation is the lesson; the question is how you find out you need it.
Practice exams at the real exam’s weights. Each full practice exam is generated fresh for that attempt, drawn at the 2024 NNAAP domain weights — physical care carrying the clear majority, exactly as the real written exam does. Questions you have not seen come first, and you never sit the same exam twice.
Drills that match how the exam is built. Drill a single topic — Activities of Daily Living, Basic Nursing Skills, Client Rights, Communication — or sit a full timed simulation. Your results break down by topic, so a weak area shows up in your practice data before it shows up on a score report.
Written-exam scope, stated plainly. Certification has two halves: a written (or oral) knowledge exam and a hands-on skills evaluation, where you perform care skills in front of an evaluator. This program prepares you for the first half. No practice-question program can rehearse being watched while you wash hands, take a blood pressure, or transfer a client — that preparation belongs in your training program’s skills lab, and we will not pretend otherwise.
Questions that stay honest. Every item in the program is monitored from real student responses. Questions students find suspiciously easy or suspiciously hard are pulled for review, and anything found wrong is fixed or retired — the bank you practice on is the bank as it should be, not as it shipped.
The real exam at a glance
Current as of October 2026, per Credentia’s NNAAP candidate materials. The table below describes the NNAAP — the most widely used CNA written exam. States that use other vendors (for example, Prometric or Headmaster) set their own item counts, skills lists, and procedures, so always confirm the details in your own state’s candidate handbook. Full detail — eligibility, the skills evaluation, registration, retakes, test day — is in our CNA exam guide.
| NNAAP written (or oral) exam — where your state uses the NNAAP | |
|---|---|
| Certification authority | Your state — certification, testing rules, and registry listing are state-run; there is no national CNA license |
| Exam program | National Nurse Aide Assessment Program (NNAAP), developed by the National Council of State Boards of Nursing (NCSBN) |
| Administered by | Credentia, in the states that contract with it |
| Written exam | 70 multiple-choice questions (60 scored + 10 unscored pretest questions mixed in) |
| Time limit (written) | 2 hours |
| Oral option | An oral examination in English or Spanish may be taken instead of the written exam if you have difficulty reading English; it must be requested when you apply. The oral form has 60 multiple-choice questions plus 10 reading-comprehension questions |
| Content domains | Physical Care Skills 64% · Psychosocial Care Skills 10% · Role of the Nurse Aide 26% (2024 NNAAP content outline) |
| Second required part | A separate hands-on skills evaluation — 5 skills in 30 minutes where the NNAAP is used (see the guide) |
| Passing standard | Set by your state — there is no single national passing score; check your state’s candidate handbook |
| Exam fee | Set by your state and its vendor — check your state’s candidate handbook; this page lists no figure because no national figure exists |
- Both parts must be passed. Passing the written exam alone does not certify you. You must also pass the skills evaluation, and your name is placed on your state’s nurse aide registry once both parts and your state’s other requirements are complete.
- The federal floor is 75 hours. Federal law (the Omnibus Budget Reconciliation Act, OBRA, implemented at 42 CFR 483.150–156) requires at least 75 hours of training — including at least 16 hours of supervised practical training — through a state-approved program, plus a competency evaluation, before registry listing. Most states require more than the floor; your state’s requirement is the one that applies to you.
- Where you test differs by part. Per Credentia’s candidate materials, the written (or oral) exam may be taken online with a live proctor or at a test center in states that offer both; the skills evaluation is offered only at a test center.
- Other vendors differ. If your state tests through Prometric, Headmaster, or another provider, expect a different question count, a different skills list, and different scheduling rules. The knowledge underneath — safe, respectful, resident-centered care — is the same, which is what this program teaches.
How the practice maps to the real exam
Every question in the national core is tagged to a topic of the 2024 NNAAP content outline — the same outline the NNAAP written exam is built from. Counts below are the core bank itself, counted question by question. The 872 state-variant questions for CA, TX, FL, NY, OH, KY, and NC sit on top of this core.
| Official outline domain and topic (2024 NNAAP outline weight) | Practice questions (core) |
|---|---|
| Physical Care Skills — 64% | 1,277 |
| Activities of Daily Living | 440 |
| Basic Nursing Skills | 697 |
| Restorative Skills | 140 |
| Psychosocial Care Skills — 10% | 200 |
| Emotional and Mental Health Needs | 160 |
| Spiritual and Cultural Needs | 40 |
| Role of the Nurse Aide — 26% | 518 |
| Communication | 140 |
| Client Rights | 160 |
| Legal and Ethical Behavior | 100 |
| Member of the Health Care Team | 118 |
| National core total | 1,995 |
| State-variant sets (CA, TX, FL, NY, OH, KY, NC) | 872 |
| Program total | 2,867 |
Basic Nursing Skills is the single largest topic in the core, just as it is the heaviest part of the real exam: infection control, safety and emergency procedures, vital signs, and the everyday clinical tasks of the nurse aide. Activities of Daily Living — bathing, grooming, feeding, elimination, mobility and comfort — is the second-largest block. Together those two topics are 1,137 of the 1,995 core questions, which is deliberate: that is where the written exam concentrates, and it is where most candidates either build a passing margin or lose one.
How to use it
- Start with free sample questions — a fixed set of questions across all three NNAAP domains, with full explanations — enough to see how the program teaches and where you stand.
- Check your state’s requirements in parallel. Before you schedule anything, confirm with your state’s nurse aide registry: your approved training route, which vendor tests in your state, that vendor’s candidate handbook, and your testing window after training. If your state does not use the NNAAP, the core still teaches the underlying knowledge — but read your own vendor’s outline alongside it.
- Drill by domain and topic. Start with Basic Nursing Skills and Activities of Daily Living, the two heaviest topics, then work outward. Keep drilling a topic until the misses stop repeating, and read the explanation even when you answer correctly — a right answer held for a wrong reason will not survive a differently worded question.
- Sit full generated exams against the clock. The NNAAP written exam allows 2 hours for 70 questions. Practice finishing with time to spare, treating every question as scored — 10 of the 70 are unscored pretest items, and you cannot tell which.
- Prepare for the skills evaluation separately, in person. Use your training program’s skills lab and your vendor’s published skills list to rehearse the hands-on half. This program covers the written exam; your certification needs both halves, and the skills half is learned by doing, with an instructor watching.
- Schedule the real exam through your state or its vendor when your practice scores sit comfortably steady on full simulations — then complete your state’s registry application steps exactly as your candidate handbook describes.
Pricing
The CNA program is $49 for full access to all 2,867 questions. If it isn’t for you once you enroll, our refund policy gives you 14 days provided you have attempted less than 20% of the program (see the site Terms for the full policy).
Verified questions
Every question in this program is original — written for PassProfessor from the official exam blueprint, never copied from a test bank or another provider’s materials. Before enrollment opened, each answer key was independently verified: reviewers re-answered sampled questions blind, disagreements were settled against the primary sources, and every numeric answer was recomputed from first principles. Questions whose facts could not be confirmed were removed, and the bank passed a text-overlap screen. Practice exams draw a fresh, blueprint-weighted set from the full bank on every attempt, so no two practice exams are the same.
Frequently asked questions
How do I enroll in the CNA program? Enrollment is open. Enroll on this page for $49 and you get immediate access to the full program — all 2,867 questions, the topic drills, and the generated practice exams — starting with free sample questions if you want to look around first.
Is there one national CNA exam? No. Per the federal framework at 42 CFR 483.150–156, CNA certification is run by each state: every state approves training programs, contracts with its own testing vendor, and maintains its own nurse aide registry. The NNAAP, administered by Credentia, is the most widely used written exam, but states using Prometric, Headmaster, or another vendor test with their own formats. Always confirm your own state’s exam in its candidate handbook.
How many questions are on the CNA written exam? Where the NNAAP is used, the written exam has 70 multiple-choice questions and a 2-hour time limit, per Credentia’s NNAAP candidate materials. Of those 70, 60 are scored and 10 are unscored pretest questions mixed in so you cannot identify them. States that use other vendors set different counts, so check your state’s handbook for the exam you will actually take.
Does this program prepare me for the skills test? No — and that limit is deliberate. This program prepares you for the written (knowledge) exam only: 2,867 practice questions with explanations, built on the 2024 NNAAP content outline. The hands-on skills evaluation, where you perform five skills in front of a Nurse Aide Evaluator, can only be rehearsed in person, in your training program’s skills lab, using your vendor’s published skills list.
What are the three domains of the NNAAP written exam? Per Credentia’s 2024 NNAAP content outline, the written exam covers Physical Care Skills at 64% of the exam, Role of the Nurse Aide at 26%, and Psychosocial Care Skills at 10%. Physical Care Skills covers Activities of Daily Living, Basic Nursing Skills, and Restorative Skills; Role of the Nurse Aide covers Communication, Client Rights, Legal and Ethical Behavior, and working as a Member of the Health Care Team.
How much training do I need before I can test? Federal law sets the floor: at least 75 hours of training in a state-approved program, including at least 16 hours of supervised practical training, under 42 CFR 483.152. States set their own requirements above that floor, and many require substantially more than 75 hours. Your state’s nurse aide registry publishes the requirement that applies to you — check there, not against the federal minimum.
What score do I need to pass the CNA written exam? Your state sets the passing standard for its competency evaluation; there is no single national passing score for CNA certification, and Credentia’s candidate materials direct candidates to their own state’s handbook for the standard that applies. Plan to practice until your full-simulation results are consistently steady across all three domains, rather than aiming at a number published for a different state.
Can I take the CNA exam orally instead of in writing? In NNAAP states, yes, if you have difficulty reading English. Per Credentia’s candidate materials, an oral examination in English or Spanish may be substituted for the written exam, and you must request it when you submit your examination application. The oral form consists of 60 multiple-choice questions plus 10 reading-comprehension questions. Other vendors offer their own arrangements — check your state’s handbook.
What happens if I do not pass? Federal rules at 42 CFR 483.154 guarantee every candidate at least three opportunities to pass the competency evaluation before retraining is required, and you must be told the areas you did not pass. States may allow more attempts than the federal floor — Credentia handbooks show three attempts in some states and four in others — and you generally retake only the part you failed. Your state’s handbook states your exact limit and window.
I am testing in a state that does not use the NNAAP. Is this program still useful? Largely, yes — with one caution. Every state’s written exam tests the same underlying body of knowledge drawn from the federal training curriculum: personal care, basic nursing skills, safety, infection control, resident rights, and communication. The caution is format: your vendor’s question count, outline weights, and skills list will differ from the NNAAP’s, so study your own vendor’s candidate handbook alongside this program rather than instead of it.
Are these the actual exam questions? No. Every PassProfessor question is written by us, from scratch, to the published 2024 NNAAP content outline and the federal nurse aide curriculum subjects. We never use real exam questions, recalled questions, or another provider’s bank — and using actual exam content would violate the candidate rules you agree to when you test.
Does this program count as CNA training? No. This is exam preparation only. It is not a nurse aide training program, provides no training hours or education credit in any state, and cannot substitute for the state-approved training federal and state rules require before you test. Complete your approved training first; use this program to prepare for its written exam.
