What is the passing score for the CNA?

The CNA is scored pass/fail — no numeric score is reported.

How many questions is the CNA?

The CNA has 70 questions with a time limit of 1 hour 30 minutes.

The Certified Nursing Assistant (CNA) credential, administered through the National Nurse Aide Assessment Program (NNAAP), is a foundational certification in healthcare. This credential demonstrates that a nursing assistant has met standardized competency requirements to provide direct patient care under the supervision of licensed nurses.

Certified Nursing Assistants work in hospitals, nursing homes, assisted living facilities, and home health settings, assisting nurses with essential patient care tasks including hygiene, mobility, vital signs monitoring, and patient comfort. The CNA role serves as a critical entry point into healthcare careers, offering a pathway for those seeking to develop clinical skills and advance into nursing or other healthcare professions.

Exam Structure and Content

The NNAAP examination is composed of two distinct components: a written (or oral) knowledge examination and a hands-on skills evaluation. Both components must be passed to achieve certification. This two-part structure ensures that candidates demonstrate both theoretical knowledge and practical clinical competency.

Training and Eligibility

Prospective CNAs must complete a minimum of 75 hours of training before attempting the examination. This training includes 16 hours of pre-contact instruction and 16 hours of supervised practical experience. These training requirements establish the foundational knowledge and clinical skills necessary for the certification exam.

Test Logistics

The written or oral knowledge portion of the examination consists of 70 questions and is completed within 90 minutes. Candidates may attempt the examination up to 3 times, allowing multiple opportunities to achieve passing scores. Registration must be completed at least 30 days prior to the test date, and candidates must remain current through the state registry, with a requirement to maintain active registry status within 24 months.

Cost and registration

The registration fee for the CNA NNAAP examination varies by state. Each state sets its own fees and testing procedures in accordance with federal regulations. Candidates should contact their state's nursing aide registry or testing administrator to confirm current fees and registration requirements for their specific location.

Exam format

The NNAAP examination consists of 70 questions administered over 90 minutes as the knowledge component, delivered either in written or oral format depending on state requirements. Candidates must successfully pass both the knowledge examination and the practical skills evaluation to earn certification. The skills demonstration evaluates hands-on competency in essential nursing assistant procedures.

How hard is the CNA?

How Hard Is the CNA Exam? The Real Difficulty

The Certified Nursing Assistant (CNA) exam, officially the National Nurse Aide Assessment Program (NNAAP), is moderately challenging but entirely achievable with proper preparation. The exam is designed to verify that candidates have mastered essential hands-on and theoretical skills needed to work directly with patients in clinical settings. Unlike high-barrier credentialing exams, the CNA is structured to be passable for anyone who completes rigorous classroom training and deliberate practice—but it still separates prepared candidates from unprepared ones.

Exam Format and Duration

The NNAAP consists of two mandatory components: a written (or oral) knowledge examination and a skills evaluation. You must pass both to earn certification. The written examination contains 70 multiple-choice questions and runs for 90 minutes, giving you roughly 1.3 minutes per question. This tight timing means you can't linger on difficult items; strategic pacing is essential.

The skills section evaluates your ability to perform core nursing assistant tasks under direct observation. You'll be assessed on critical competencies like patient hygiene, vital signs, infection control, communication, and safe handling techniques. Unlike the written test, the skills evaluation has no fixed time limit—evaluators assess whether you can perform each task correctly and safely.

What You Need Before Taking the Exam

Credentia administers the NNAAP, and all candidates must complete a formal nurse aide training program before sitting for either component. Programs must provide a minimum of 75 hours of training covering both theoretical knowledge and hands-on skills. Within those 75 hours, trainees must complete at least 16 hours of supervised practical training in clinical settings and another 16 hours of foundational instruction in areas like communication, infection control, and patients' rights before any direct resident contact.

This prerequisite barrier is real: you cannot skip training and walk into the exam. However, it also means that if you complete an accredited program, you've already absorbed the core material the exam tests.

Exam Difficulty: What's Actually Tested

The knowledge section focuses on practical scenarios rather than memorization. Questions test your judgment in patient care situations—how to respond to a confused resident, when to report vital sign changes, proper body mechanics to prevent injury, and infection control in realistic conditions. Few questions are pure trivia; most require application of core principles to safe practice.

The skills section is where most candidates encounter real difficulty. Evaluators aren't looking for perfection—they're verifying that you can safely perform essential tasks. Common failure points include poor infection control (forgetting hand hygiene, contaminating sterile fields), unsafe patient handling, inability to communicate clearly with residents, and incomplete vital sign measurements. These are learnable and fixable through deliberate practice.

Pass Rates and Realistic Difficulty

While national pass rate data is limited, state-level data and program-reported outcomes suggest first-attempt pass rates range between 70 and 85 percent for fully trained candidates. Candidates who fail typically struggle with one of two areas: the skills section (due to safety violations or incomplete task performance) or the written test (due to poor time management or misunderstanding scenario-based questions). The good news is that you have multiple opportunities to retest—candidates are guaranteed at least three exam attempts before dismissal from most programs, giving you genuine second chances to address weak areas.

Realistic Study Plan

Start with your program's curriculum as your foundation. Most accredited programs distribute 75 hours across 8 to 12 weeks, so your study period is time-bound. Beyond classroom hours, add 2 to 4 weeks of focused preparation after completing your formal training.

  • Weeks 1–6 (During formal training): Attend all classroom and lab sessions. Take active notes. Perform each skill repeatedly in lab practice until it feels automatic. Ask instructors for feedback on your technique.
  • Weeks 7–8 (Focused prep after training): Take full-length practice exams under timed conditions to get comfortable with the 90-minute constraint. Score yourself honestly. Spend extra time on any section where you score below 80 percent. Practice skills scenarios with a partner or instructor—someone who can identify safety gaps you might miss.
  • Days before exam: Light review of high-yield facts. Get full sleep the night before. Arrive early to the testing center to settle nerves.

Cost and Registration

Training program costs vary widely by region and provider—expect $500 to $2,000 for a complete CNA program, though some community colleges and unions offer subsidized options. Exam fees typically range from $100 to $300, depending on your state's registry. Once you pass both components, your state must register you within 30 days of completion, creating an official public record that employers can verify. Your registration remains active as long as you're employed in nursing or nursing-related work; if you perform no nursing services for 24 consecutive months, your registration becomes inactive and requires renewal.

Career Value and Job Prospects

The CNA credential is immediately relevant: you cannot legally work as a nursing assistant in most settings without certification and registration in your state's registry. It's the gateway credential for roles in hospitals, nursing homes, assisted living, home care, and clinics. The job market for CNAs remains strong—healthcare employment continues to grow, and the hands-on, patient-facing nature of the role creates consistent demand.

Many CNAs use the credential as a stepping stone: it provides direct patient care experience that nursing school prerequisites require, real-world understanding of clinical workflow, and often tuition assistance from employers. Entry-level hourly pay typically ranges from $12 to $16 per hour, depending on location and facility type, with benefits like health insurance and shift flexibility making it a viable entry point into healthcare.

Bottom Line

The CNA exam is fair and achievable. It's not designed to filter out determined candidates—it's designed to filter out unsafe ones. If you complete your training program actively (not passively), practice skills until they're automatic, and take practice exams seriously, passing becomes highly likely. The written test requires careful reading and time management; the skills section requires hands-on confidence and safety awareness. Both are built during your required training hours, not discovered on exam day. The credential opens doors quickly in healthcare and costs far less in time and money than higher-level credentials, making it one of the fastest, most practical entry points into patient care work.

How the CNA compares to related exams

The Certified Nursing Assistant (NNAAP) exam and NHA's allied-health certifications — the Certified Phlebotomy Technician (CPT) and Certified EKG Technician (CET) exams — all open doors to entry-level roles in patient care, but they credential very different skill sets. This page compares the three so you can pick the credential that matches your career goal, or plan a stackable path across them.

Scope of practice

The CNA (NNAAP) certifies broad, hands-on personal care: activities of daily living, mobility and transfers, vital signs, infection control, and resident rights across long-term care and hospital settings. The Certified Phlebotomy Technician exam is narrow and specialized — it focuses on venipuncture, capillary draws, specimen handling, and lab safety. The Certified EKG Technician exam is likewise focused, covering electrocardiogram setup, lead placement, rhythm recognition, and Holter/stress-test support.

Exam format and difficulty

The NNAAP has a written (knowledge) component and a separate hands-on skills evaluation, and you must pass both parts to earn the credential. The written portion consists of 70 multiple-choice questions with a 90-minute time limit. By contrast, the NHA phlebotomy and EKG exams are knowledge-based multiple-choice tests; hands-on competency is typically demonstrated through program clinical hours rather than a standardized skills station. Difficulty is comparable at entry level, but the CNA's dual written-plus-skills structure means candidates must prepare for a proctored practical demonstration in addition to a written test.

Who each is for

Choose the CNA if you want to work directly with patients in nursing homes, hospitals, or home health, and want the most transferable entry point into nursing. Choose phlebotomy if you prefer a specialized, lab-oriented role with focused technical skills and less full-body patient care. Choose EKG if you're drawn to cardiac and diagnostic work and want a niche technical credential, often in cardiology clinics or telemetry units.

Prerequisites

All three are entry-level credentials that generally require a high-school diploma or equivalent and completion of an approved training program; none requires a prior nursing degree. Exact prerequisites — training hours, age minimums, and background checks — are set by your state and the certifying body, so confirm the current requirements with your program before enrolling.

Ways to prepare for the CNA

Preparing for the Certified Nursing Assistant (NNAAP) Exam doesn't have to cost money. A wide range of free resources — practice questions, skills videos, and public content outlines — can carry many candidates all the way to a passing score. Paid courses and books add structure, deeper explanations, and hands-on skills coaching that some learners need. This page compares the two honestly so you can decide where to spend your time (and whether to spend any money at all).

What you're preparing for

The NNAAP is split into a written (or oral) knowledge test and a hands-on skills evaluation, and you must pass both parts to earn certification. The written portion is 70 multiple-choice questions with a 90-minute time limit. Knowing this shape matters when you weigh free versus paid prep: free resources cover the knowledge test well, while the skills evaluation is where guided, hands-on practice tends to pay off most.

Free study options vs. paid prep

DimensionFree resourcesPaid courses & books
Cost$0 — practice quizzes, YouTube skills demos, official candidate handbooks and content outlinesTypically ranges from an inexpensive review book to a full online course fee
StructureYou assemble your own study plan from scattered sourcesSequenced lessons, a set schedule, and progress tracking
Knowledge test coverageStrong — abundant free practice questions and flashcards existStrong, with more detailed rationales for wrong answers
Skills evaluation helpFree step-by-step videos, but no personalized feedbackStructured skill checklists, and sometimes in-person or coached practice
AccountabilitySelf-driven; requires disciplineBuilt-in deadlines and, in some programs, instructor support

When each option makes sense

Free is likely enough if you…

  • Are a self-directed learner who can build and follow your own plan
  • Have recent hands-on experience or a training program covering the skills
  • Mainly need practice questions and repetition to feel exam-ready

Paid prep is worth considering if you…

  • Want a guided, start-to-finish curriculum instead of piecing sources together
  • Feel shaky on the hands-on skills and want structured checklists or coaching
  • Benefit from deadlines, tracking, and answer explanations to stay on pace

A practical hybrid approach

Many candidates get the best value by starting free — official candidate handbooks, free practice questions, and skills videos — and only paying for a targeted resource where they're weakest. A single focused review book or a short course covering the skills evaluation often closes the gap without the cost of a full program. Because the written test is a fixed 70 questions in 90 minutes, timing yourself on free practice sets is one of the highest-value things you can do at no cost.

Weighing a paid course

Each of these is a side-by-side on what the provider does better than we do, what it charges today, and where the free path here is enough.

Frequently asked questions

What is the CNA (NNAAP) exam?

The NNAAP is the certification exam most states use to license certified nursing assistants. It has two parts: a written (or oral) knowledge test and a hands-on skills evaluation where you perform nursing-assistant tasks in front of an evaluator. You must pass both parts to be listed on your state's nurse aide registry.

How many questions are on the CNA written exam, and how long do I get?

The written portion has 70 multiple-choice questions with a 90-minute time limit. That works out to a little over a minute per question, which is comfortable for most candidates who have prepared. The skills portion is timed separately and depends on which skills you are assigned.

What score do I need to pass the CNA exam?

You must pass both the written test and the skills evaluation to earn certification; failing either part means retaking that part. The exact written cut score and skills scoring criteria vary by state, so confirm the current requirements with your state's nurse aide registry or the NNAAP candidate handbook for your state.

How much does the CNA exam cost?

Fees are set state by state and differ depending on whether you take the written, oral, or skills portions, so there is no single national price. Some employers and training programs cover the fee for new aides. Check the current fee schedule in your state's NNAAP candidate handbook or with your state's nurse aide registry before you register.

How do I register for the CNA exam?

You register through your state's testing arrangement after completing a state-approved nurse aide training program. Most states route registration through the NNAAP program administered by their testing vendor, and your training program can usually confirm the exact steps. Start with your state's nurse aide registry or the NNAAP candidate handbook for your state to find the current application process.

Where should I start studying for the CNA exam?

Start by reviewing the content outline in your state's candidate handbook, then drill free practice questions to find your weak areas. Focus your review on the topics you miss most, and practice the hands-on skills until you can perform them from memory. Free practice questions, a printable cheat sheet, and topic reviews are available on this site with no signup required.

How hard is the CNA (NNAAP) exam?

The CNA exam is manageable for candidates who prepare, but it tests you on two fronts: a written portion of 70 multiple-choice items and a hands-on skills assessment, and you must pass both parts to earn certification. The written section gives you 90 minutes, which is enough time to work carefully through each question. Because the difficulty comes from the breadth of care topics rather than trick questions, steady review of core skills is usually what separates passing from failing.

What is the passing requirement for the CNA exam?

To pass, you must succeed on both the written and skills assessments — passing only one is not enough to certify. The written test consists of 70 multiple-choice items delivered within a 90-minute window. Treating the two sections as equally important is the safest way to plan your preparation.

How long is the CNA written exam and how many questions does it have?

The written portion of the CNA exam gives you 90 minutes to answer 70 multiple-choice items. That works out to a little over a minute per question, so pacing is comfortable if you avoid getting stuck on any single item. Remember that this written test is only one half of certification — you also have to pass the skills assessment.

How should I study for the CNA exam?

Study for both halves of the exam at once, since you must pass both the written and skills assessments to certify. For the written section, practice answering 70 multiple-choice questions under a 90-minute timer so the pacing feels familiar on test day. Pairing timed question practice with repeated hands-on rehearsal of clinical skills covers both requirements at the same time.

How much time will I have on the written portion of the CNA exam?

You'll have 90 minutes for the written portion of the CNA exam. In that time you need to work through 70 multiple-choice items, which leaves room to review flagged questions before submitting. Managing that time well matters because the written test is one of two parts you must pass to earn your certification.

Which exam is easier — CNA, phlebotomy, or EKG?

All three are entry-level and comparable in academic difficulty, but the CNA (NNAAP) adds a separate hands-on skills evaluation that you must pass in addition to the 70-question, 90-minute written test. The phlebotomy and EKG exams are primarily knowledge-based, so candidates who are nervous about a proctored practical demonstration may find those single-format tests more approachable.

Can I stack these certifications?

Yes — these credentials complement each other well. Many patient-care professionals start with the CNA for broad experience, then add phlebotomy or EKG certification to expand into specialized, better-paid technical roles. Because each focuses on a different skill set, combining them can make you a more versatile candidate, though the exact value depends on your local job market and employer needs.

Do phlebotomy and EKG exams also have a separate skills test like the CNA?

Unlike the CNA (NNAAP), which requires passing both a written test and a standardized skills assessment, the NHA phlebotomy and EKG certification exams are typically knowledge-based multiple-choice tests. Hands-on competency for those credentials is usually verified through required clinical or externship hours in your training program rather than a separate proctored skills station.
