Your Complete Guide to CNA Testing and State Certification Exams

Introduction: Your Guide to Passing the CNA Exam

What does it actually take to pass the CNA exam and earn your CNA certification? For most states, passing requires clearing a two-part assessment: a written (or oral) knowledge test and a hands-on skills evaluation. Both parts must be passed within a defined window, and a failed attempt can delay your start date by weeks.

Demand for certified nursing assistants is climbing. With over 1.38 million CNAs currently employed nationwide and a median annual wage of $39,530, the credential opens one of the more stable entry points into direct patient care. Exam fees typically run between $100 and $200 total, though that figure shifts by state and testing vendor.

Candidates often underestimate the skills component. Written knowledge can be reviewed at home, but demonstrating clinical procedures in front of a live evaluator requires a different kind of preparation. State-specific rules around retakes, testing center locations, and accepted training programs add another layer of complexity that catches first-time candidates off guard.

What Is the CNA Exam?

The biggest hurdle between your CNA training and a stable healthcare career, and ultimately landing your first CNA job, isn't the coursework or the clinical hours: it's walking into that testing room and proving you can perform when it counts. The CNA exam is the final gateway, designed to ensure every certified nursing assistant meets a uniform standard of safety and care. Think of it less as a test of memory and more as a demonstration of real-world readiness.

The Two-Part Exam Structure

The exam is split into two distinct components, each measuring a different kind of competence:

• Written (or oral) knowledge test: This section checks your understanding of nursing principles, resident rights, infection control, and basic emergency procedures. In most states, you can request an oral version if reading is a barrier, but the content remains the same.
• Hands-on skills evaluation: Here, you perform a set of randomly selected clinical tasks in front of an evaluator. You'll be graded on your technique, safety habits, and ability to communicate with a "client" (often a fellow test-taker acting as a patient).

You must pass both parts to earn a spot on your state's nurse aide registry. Failing one often means retaking just that portion, though state rules vary.

Who Administers the Test?

State nursing boards don't usually run the exam themselves. Instead, they contract with third-party vendors like Prometric, Pearson Vue, or regional assessment centers. These organizations handle scheduling, test-day logistics, and score reporting. This separation keeps the evaluation objective: your instructor won't be the one deciding if you pass.

What to Expect in This Guide

The pages ahead walk you through every detail of the process. You'll find breakdowns of typical costs, registration steps, a skills list with preparation tips, and policies for retakes if things don't go as planned. By the end, you'll have a clear roadmap from the day you sign up to the moment you see your passing score.

How Much Does the CNA Test Cost?

The total cost for both parts, the written exam and the skills evaluation, typically falls between $100 and $200.

Average Exam Fees

Some states bundle the written (or oral) and skills portions into a single fee, while others charge separately. In many regions, the written exam runs $40 to $60, and the skills test adds $60 to $120. These fees go directly to the testing vendor, not your training school.

Factors That Affect Cost

The price you pay depends on a few key variables. Each state selects its own approved vendors, like Pearson VUE, Prometric, or a regional contractor, so prices shift from one state to the next. Retakes also affect your total: if you fail one section, you usually pay only that section's fee again, but redoing the full exam means paying the entire amount. Some states offer a free or discounted reattempt within a window, but most charge each time.

Who Pays?

Your upfront cost can be zero in several common scenarios. Many CNA training programs bundle one exam attempt into tuition, so verify this before you enroll. Employers, especially nursing homes and hospitals, frequently reimburse the fee after you are hired, sometimes as part of a signing bonus or tuition assistance. If your program or employer does not cover it, budget for the exam itself plus possible travel to the testing center.

Later in this guide, you will find a state-by-state breakdown of exam fees and retake policies. For now, check the cna requirements with your state's nursing board to confirm the exact cost in your area. Most testing centers also list current fees on their websites, so a quick online search can give you a solid estimate.

What CNAs Earn: The Payoff

Certified Nursing Assistants earn a median annual wage of $39,530, with over 1.38 million employed nationwide.

CNA Skills Test: Common Skills and How to Prepare

The CNA skills test determines whether you can safely perform essential patient-care tasks under pressure. Unlike the written exam, this portion requires you to demonstrate clinical competence in front of an evaluator, following precise steps. Every action is scored, from patient privacy to infection control.

Commonly Tested Skills

CNA programs prepare you in roughly 25 hands-on procedures. The list below covers the core set from major testing vendors like Prometric and Pearson Vue:

• Handwashing: Proper soap-and-water technique to prevent infection.
• Donning and Removing PPE: Putting on and taking off protective equipment in the correct order.
• Fowler's Position: Placing the resident upright or semi-upright for breathing or comfort.
• Side-Lying Position: Turning the resident onto one side for pressure relief or procedures.
• Transfer Bed to Chair with Gait Belt: Safely moving a resident using proper body mechanics and a gait belt.
• Ambulation with Gait Belt: Assisting a resident to walk while guarding against falls.
• Occupied Bed Making: Changing linens while the resident remains in bed, maintaining privacy.
• Partial Bed Bath (Upper Body): Washing face, neck, arms, chest, and abdomen.
• Perineal Care (Female): Cleaning the genital and perineal area to reduce infection risk.
• Catheter Care (Female): Cleaning around the catheter and drainage area.
• Mouth Care: Cleaning the mouth and teeth for a dependent resident.
• Denture Care: Cleaning and handling dentures properly to prevent damage.
• Dressing a Resident with Weak/Paralyzed Arm: Dressing the affected side first, undressing it last.
• Feeding a Dependent Resident: Positioning, assisting with eating, and monitoring intake.
• Measuring Weight: Weighing an ambulatory resident and documenting the result.
• Radial Pulse: Counting and recording pulse rate accurately.
• Respirations: Counting breathing rate without alerting the resident.
• Blood Pressure: Taking and recording blood pressure manually or electronically.
• Passive Range of Motion (Upper Body): Moving shoulders, elbows, wrists, and fingers through allowed motion.
• Passive Range of Motion (Lower Body): Moving hips, knees, ankles, and toes to maintain mobility.

Some states add extra tasks like measuring urinary output, using an electronic blood pressure cuff, or performing oxygen-related care.¹ Always review your state's official candidate handbook for the exact list.

How the Skills Test Works

On test day, you will randomly draw a subset of skills, usually between 3 and 6 tasks. Handwashing is almost always one of them, because it is a fundamental infection-control measure. An evaluator watches and scores each action against a detailed checklist. Missing a critical step (for example, forgetting to apply gloves during perineal care) can result in an automatic failure for that skill. But you generally continue the test, and you can still pass the overall exam if you perform well on the other skills.

Tips for Effective Preparation

• Practice with a classmate: Hands-on repetition builds muscle memory and helps you remember the sequence of steps. Take turns being the evaluator and the nurse aide.
• Use the official checklist: Your state's testing vendor (Prometric, Pearson Vue, etc.) publishes the exact scoring criteria. Practice until you can perform each task without looking at the list.
• Watch demonstration videos: CNA Training Videos on official channels often show model performances. Pay attention to small details like knocking before entering the room and introducing yourself.
• Narrate your actions: During practice and the test, speak aloud what you are doing. It shows competence and can help you stay on track.

Failing the Skills Test? You Can Retake It

Failing the skills test rarely means starting from scratch. Most states let you retake only the skills portion, not the written exam. You usually get two or three attempts, often within a set time frame and for a reduced fee. Check your state's retake policy, and if you fail, focus your practice on the tasks you missed. Many candidates pass on a second try with targeted preparation.

Questions to Ask Yourself

What’s on the CNA Written Exam?

The written portion of the CNA exam is designed to measure the knowledge you gained during your training program. It covers the essential theory behind the hands-on care you’ll deliver every day.

Exam Structure and Timing

While the exact format varies slightly by state and testing vendor, you can expect a multiple-choice test with 60 to 70 questions. National norms land in the 60-70 range, though some states like Washington and California use 70 questions, while New Jersey administers 60. The time limit is typically generous: 90 to 120 minutes. For example, California allows 120 minutes, and Prometric-administered exams give 90 minutes. You’ll have enough time to read carefully and review your answers, but it’s smart to pace yourself.

What the Exam Covers

The content is organized into three broad domains:

• Physical care skills – bathing, dressing, feeding, positioning, and vital signs.
• Psychosocial care – addressing emotional and mental health needs, communication with residents.
• Role of the nurse aide – professional conduct, legal and ethical responsibilities, and working as part of the healthcare team.

Within those domains, the test drills down into specific topics that you’ll encounter daily. These include:

• Role and responsibilities of a CNA
• Communication and interpersonal skills
• Infection control procedures
• Safety and emergency protocols
• Personal care and hygiene
• Basic nursing skills (e.g., measuring output, range of motion)
• Mental health and social service needs
• Restorative services and rehabilitation
• Residents’ rights and independence

Passing Scores and State Variations

To pass, you generally need to score between 70% and 80%, but the threshold depends on your state. Washington and California set the bar at 70%, while New Jersey requires a 75%. Because a majority of the questions are drawn from the same core knowledge base, a solid understanding of the material usually translates across state lines. Check with your state’s nursing board or testing vendor for the exact percentage and any additional requirements.

How to Prepare for the Written Test

Start by reviewing your course textbooks and notes, then focus on areas where CNAs in the field say they’re tested most often:

• Terminology: Master medical terms and abbreviations that appear in care plans and facility policies.
• Resident rights: Understand the principles of dignity, privacy, and independence. Questions often present scenarios where you must choose the response that protects those rights.
• Infection control: Hand hygiene, standard precautions, and proper use of personal protective equipment show up repeatedly.
• Safety: Fall prevention, emergency fire response, and handling of hazardous materials are common.

Take practice tests under timed conditions to build confidence. When you miss a question, dig into the explanation, not just the correct answer, to reinforce your reasoning. Many successful test-takers also form study groups to quiz each other on tough concepts like restorative care and psychosocial scenarios.

Where and When Can You Take the CNA Test?

Most states contract with one primary testing vendor, such as Prometric or Pearson VUE, to administer the CNA exam at regional testing centers across the state. These centers are often located in community colleges, vocational schools, or dedicated testing facilities. The availability of testing sites varies significantly by state: larger states like California and Texas may offer dozens of locations per region, while smaller or rural states may have only a handful of centers statewide.

Scheduling Your Exam

You become eligible to schedule your CNA test only after you have successfully completed a state-approved training program. Your training school will typically provide you with instructions and a candidate eligibility form that you submit to the state testing agency or vendor. Once your application is processed (usually within one to two weeks), you will receive authorization to schedule both the written and skills portions of the exam.

Most testing vendors allow online scheduling through a candidate portal. You will select your preferred date, time, and location from available slots. Peak times, such as the weeks immediately following high school graduation or the end of semester, fill quickly. It is common for candidates to wait two to four weeks for an appointment in urban areas during busy periods, while rural sites may have openings within days.

Testing Location Flexibility

Some states permit you to test at any approved center within the state, giving you the option to choose a site closer to home or one with earlier availability. Other states assign you to a testing region based on where you trained or your residential address. A few states conduct skills testing on-site at your training facility, eliminating the need to travel to a separate location for that portion of the exam.

State-Specific Providers and Sites

Because testing vendors, procedures, and site availability differ by state, consult the state-specific table at the end of this article for the exact testing agency, typical wait times, and links to scheduling portals in your state. If you are training near a state border, verify that you are scheduling with the correct state's vendor, as neighboring states do not share testing systems or reciprocal scheduling.

CNA Exam Retake Policies: What if You Don’t Pass?

Not passing the CNA exam on your first try is more common than most candidates expect, and retake policies have remained fairly consistent across most states even as testing formats evolve. The good news is that every state provides a clear path for retaking the exam, so a single setback doesn’t have to derail your career plans.

How Many Attempts Do You Get?

Most states allow candidates up to three attempts to pass the CNA competency exam within a set window, often two years from the date you complete your training program. A few states are more generous and permit additional tries, while others enforce a stricter timeline. If you exhaust all of your allowed attempts without passing, many states require you to retake an approved CNA training program before you can test again.

Do You Have to Retake the Entire Exam?

One of the most reassuring details for test-takers is that, in the majority of states, you only need to retake the portion you did not pass. The CNA exam has two components: a written (or oral) knowledge test and a clinical skills evaluation. If you pass the written section but fall short on the skills demonstration, you typically only need to retake the skills test, and vice versa. This saves both time and money, though the passing score you earned on one section usually has an expiration date, so don't wait too long before scheduling your retake.

Retake Fees and Additional Requirements

Each retake generally comes with its own testing fee, which can range from around $25 to over $100 depending on the state and which portion you are retaking. Some training programs or employers will cover retake costs, so it’s worth asking before paying out of pocket. After two or three unsuccessful attempts, certain states also require candidates to complete remedial coursework or additional clinical hours before they are eligible to sit for the exam again. This requirement is designed to help you strengthen the areas where you struggled rather than simply retaking the same test unprepared.

Check Your State's Specific Rules

Retake rules vary meaningfully from state to state, including the number of attempts allowed, the timeframe for retesting, fee amounts, and remedial training requirements. Before you schedule a retake, consult the state-specific testing requirements table below to confirm the exact policy where you plan to become certified. You can also visit your state's nurse aide registry or testing vendor website for the most current information.

Not passing a section of the CNA exam is a temporary obstacle, not a dead end. Give yourself time to review your weak areas, use practice tests and study guides, and approach your next attempt with a focused plan. Most candidates who prepare strategically after an initial failure go on to pass and begin rewarding careers in healthcare.

Top CNA Practice Tests and Study Resources

The right study materials can make all the difference when you are getting ready for the CNA state exam. Rather than guessing what might appear on the test, start with resources that are built around the actual exam format and content. Below are the most reliable cna training resources, including practice tests, study guides, and free tools to help you walk into the testing center confident and prepared.

Start with Official Testing Vendors

The companies that administer the CNA exam in your state are your most direct source for accurate practice material. Two of the most common vendors are Prometric and Pearson Vue. Their candidate websites typically include sample questions, test format overviews, and full-length practice tests, sometimes at no cost and sometimes for a small fee. These resources mirror the style and difficulty of the real exam, so they are excellent for both the written portion and preparing for the manual skills checklist. Look for the candidate handbook or exam preparation tab on the site that corresponds to your state.

Check Your State's Nurse Aide Registry

Your state's nurse aide registry website, which is usually part of the department of health or a similar agency, often provides a list of approved study materials. Many state pages go a step further and publish free practice exams or step-by-step breakdowns of required skills. Because each state sets its own testing requirements, the information you find here is more likely to match what you will actually see on exam day. Bookmark this official site early in your study planning.

Look to Professional Associations

Organizations designed to support nursing assistants can be another solid resource. The National Association of Health Care Assistants (NAHCA), for example, offers educational guides and sometimes member-only study tools. State-level CNA associations and some local chapters of larger nursing organizations also compile recommended practice tests or host review webinars. These groups understand the exam from the candidate's perspective and often share tips that go beyond the handbook.

Explore Free and Low-Cost Online Tools

Beyond official channels, you will find a wide range of free CNA practice quizzes and flashcards on general education websites and through community college career centers. While these can be helpful for building comfort with multiple-choice questions and timing, always cross-check them against your state's current exam outline. A quick call to your training program instructor or a visit to the U.S. Bureau of Labor Statistics website for related healthcare careers can also point you toward vetted state-specific resources.

State-Specific CNA Testing Requirements

CNA testing sits at an awkward intersection: it is a national credential in spirit, but every state sets its own price, vendor, and rules. That means the exam you take in Albany looks different from the one offered in Salt Lake City, and the fee you pay in Miami may not match what your neighbor paid across the state line. Before you register, confirm the details with your state's nurse aide registry or the vendor it contracts with.

The Major Testing Vendors

Most states outsource CNA testing to one of three national vendors. Knowing which vendor your state uses is the first step to finding accurate fees, scheduling windows, and study materials.

• Prometric: Administers the exam in states including New York and Florida. In New York, expect roughly $115 for the written and skills combination, or $135 if you take the oral version instead of the written. Retakes are priced per portion (about $57 written, $67 oral, $68 skills), so you only pay for what you need to retake.¹ Florida runs a flat exam fee of around $155.²
• Credentia (NNAAP): Handles testing for a large share of states and the District of Columbia. In DC for 2026, candidates can expect fees in the $167 to $192 range depending on which portions are bundled.
• D&SDT-Headmaster: Used by states like Utah, where each portion (written and skills) runs about $55, for a combined total near $110.

Other states use Pearson VUE, Regional Testing Services, or state-run programs. Fees nationwide typically fall between $80 and $200 for the full exam.

What to Verify for Your State

Because fees, retake windows, and reciprocity rules change often, treat any published table (including this one) as a starting point rather than the last word. When you check your state's registry, look for six specific data points:

• State and testing provider: Confirm which vendor is currently under contract. Contracts rotate every few years.
• Written exam fee: The knowledge portion, sometimes offered as an oral exam for candidates who prefer it.
• Skills exam fee: The hands-on demonstration, usually priced separately or bundled.
• Retake policy: Most states allow up to three attempts within two years of finishing your training program. After that, you generally have to retrain.
• Reciprocity notes: If you are certified in another state, moving your credential often requires an application, a background check, and proof that your original certification is active and in good standing. Some states also have pathways for military medics, foreign-trained nurses, and nursing students who completed a fundamentals course.

How to Find Current Numbers

Instead of relying on a generic chart, go straight to the source. Search for your state name plus "nurse aide registry" to land on the official page that lists the current vendor, fee schedule, and application forms. Credentia and Prometric also publish state-by-state fee pages that are updated regularly. If a number on cnaclasses.org or any other third-party site does not match what the registry shows, always trust the registry.
