How to Pass CNA Written Exam: A Proven Roadmap to First-Time Success

For many individuals looking to get into the healthcare industry, the stress of having to complete a three-digit countdown clock as they ponder the answer to a question about fluid intake is enough to make anyone break into a cold sweat. You may have spent the hours and clinical requirements to get your feet wet in the world of healthcare and have mastered the art of the bed bath. However, the cna written test is the last hurdle that stands between you and your future as a nurse aide. While many individuals fail this portion of the test because they have no idea how to apply the “tester logic” that is required to pass the Prometric or Credentia registries.

The statistics show that 85 to 90 percent of individuals pass this portion of the test, however, this still equates to thousands of students having to spend the money and time to retake the test. While it is possible to memorize enough information to get through this portion of the test, it is also important to understand how to apply this information to ensure patient safety.

Navigating the Different Testing Vendors

There are different testing providers such as Credentia, Prometric, or HDMaster, and it depends upon the state where you take the test from. Even though the material is all relatively the same, the format of the tests varies slightly.

Vendor	Number of Questions	Time Limit	Passing Score (Approx.)
Credentia	70	120 Minutes	70-80%
Prometric	60	90 Minutes	Variable by State
HDMaster	75	90 Minutes	70-75%

The Five Pillars of the Knowledge Exam

The cna written test is not just random facts and figures about medicine. It is weighted according to certain domains of care. Knowing this allows you to focus your study time for maximum benefit.

1. Physical Care Skills (45-50% of the test)

This is the “meat” of the test. You will be asked about activities of daily living (ADLs), restorative care, and basic nursing requirements.

The Nuance: Remember that math is involved in this type of question. You will possibly have to calculate how much fluid is in milliliters (mL) or cubic centimeters (cc). Remember, 1 ounce is equal to 30 mL. If your patient consumes 6 ounces of juice, this is equivalent to 180 mL.

2. The Role of the Nurse Aide (15-18%)

This section tests your knowledge of legalities and ethics.

Pro Tip: If you are asked what you should do in case you witness another aide being rough with a patient, you should always report them. The test doesn’t care about social cliques in the nursing home. It only cares about the law.

3. Psychosocial Care Needs (7-10%)

This section deals with the emotional well-being of your patient.

The Logic: If your patient with dementia wants to wear two different shoes and it doesn’t interfere with their mobility, let them! The test is more concerned with “person-centered care” than “facility-centered care.”

4. Communication and Interpersonal Skills (10-12%)

How do you communicate with a hard-of-hearing patient? How do you deal with an angry family member?

The Nuance: Be on the lookout for answers that include good listening skills and face-to-face interaction. Steer clear of any answer that includes the word “ignoring” or “arguing.”

5. Infection Control & Safety (12-15%)

Be prepared for the phrase “Standard Precautions” to come up a lot. Hand washing is the answer you should give when the question relates to the spread of disease, as it is the “gold standard” answer.

Why Practice Tests Matter (and How to Use Them)

Reading a textbook alone simply won’t cut it. Practice tests mimic the mental process of the real cna knowledge test.

In taking the free cna written test practice, you should check the results, but more importantly, you should ask yourself why you failed the question. Was it because you didn’t know the answer, or did you misread the “distractor,” the answer that sounds right but isn’t?

Leveraging a CNA Written Practice Test Effectively

According to studies, testing oneself on the material is 50% more effective than reviewing the material. Use the nnaap practice test to identify your “red zones.” If you’re consistently failing questions on catheters or blood pressure, stop taking practice tests and dig deep into the chapters.

The “Safety First” Rule of Testing

In case you’re stuck between two answers on the CNA written exam practice, remember the rule: if you’re stuck, the answer you should give is the one that ensures the safety of the resident.

For example, if the question relates to the transfer of a patient:

A) Move them as quickly as possible.

B) Use a gait belt and lock the bed wheels.

C) Ask the patient to hold onto your neck.

D) Do it alone to save time.

Only B deals with safety and injury prevention. The test is meant to determine if you’re a ‘safe’ practitioner, not necessarily the fastest.

Overcoming Test Anxiety with Data

As per reports received from state boards, 15% of test-takers do not pass the written test on the first attempt. What’s really interesting is that most of these test-takers do not fail because they do not know the answers, but because of ‘overthinking.’

The test is especially hard for medical assistant students or nursing students, as they try to use high-level critical thinking for simple aide tasks. Don’t. Just remember, you’re an aide. Use the ‘Aide Scope of Practice.’ You don’t diagnose; you report. You don’t prescribe; you assist.

Common Pitfalls to Avoid

Ignoring the ‘Except’ or ‘Not’ Questions: These questions are meant to trick you. Read the stem of the question twice.

Applying ‘Bad Habits’ from the ‘Real World’: In the ‘real world,’ you’ll see people transfer patients without a gait belt to speed up the process. On this test, this is a failing offense. Use the ‘real world’ textbook, not the ‘real world’ you observed during clinical.

Mismanaging Time: You’re allotted 1.5 to 2 minutes per question (unless you’re on the HDMaster clock). That’s plenty of time. If you’re having trouble with a question about the chain of infection, flag it and go on. Don’t allow one hard question to destroy your confidence for the next ten.

Resources for Final Review

Before you go to take your test at the testing center, take a practice cna written exam that includes rationales. This way, you know why you are selecting each correct answer. This is where you learn the “why” instead of just the “what.”

Regardless of whether you are taking a credentia cna written exam or a state-specific board exam, it is better to space out your studying instead of cramming. Spend 30 minutes per day for two weeks using a free cna written test practice leading up to your actual test date. This is scientifically proven to help you retain information in your long-term memory instead of just your short-term memory.

Frequently Asked Questions

What score do I need to pass on my knowledge exam?

For most states and testing companies, you need to score at least 70-80%. This means that for a 70-question test, you need to get at least 49-56 questions correct in order to pass.

Can I take my test in another language instead of English?

Yes, most states offer this option. Some offer Spanish, and others offer an “Oral Exam” where you wear headphones and they read you each question. Be sure to check your state’s registry requirements because you may need to prove your English proficiency for certain tests.

What are my options if I do poorly on my written test but pass my CNA skills test?

For most states, you only need to retake the part you failed. However, you are only allowed three attempts and two years from the date you finished your training program. If you do poorly on both tests, you are required to retake your entire training program.

How soon can I get my results?

For most computer-based tests taken at a testing center, you should get your unofficial results within 24-48 hours after taking your test. You should be able to view them on their website. Paper-based tests take two weeks to process.
