The NCLEX-RN, which includes 85 to 150 questions, must be finished in five hours. Unlike other medical exams or standardized tests, it doesn’t have a fixed passing score or percentage. Instead, a computerized algorithm evaluates each candidate’s ability against an established passing standard to determine whether they pass or fail.
If a student reaches the five-hour test limit (including breaks) and/or answers all 150 questions, the exam will end. However, if test-takers answer enough questions for the computer to reliably determine whether they will pass or fail before they reach the time or question limit, the exam ends automatically. Knowing the exam format will allow you to prepare better ahead of exam day and avoid any last-minute surprises.

NCLEX-RN exam information
The National Council Licensure Examination for Registered Nurses (NCLEX-RN) is a computer-adaptive licensing exam for nursing graduates with bachelor’s, associate’s, or certificate credentials. It is administered by the National Council of State Boards of Nursing (NCSBN). Passing this exam is necessary to practice as an RN in the U.S., Canada, and, for some international candidates, Australia. The NCLEX can be taken at Pearson Professional Testing locations, which can offer accommodations for digital exams.
Preparing for the NCLEX-RN involves developing a detailed study plan and schedule, reviewing key content areas, practicing questions, and pinpointing topics that need extra focus. Passing this test demonstrates that a nursing program graduate is qualified to obtain licensure and practice at the entry level.
While not having a fixed passing score to target might make studying challenging, knowing the structure of the exam will help you develop smart test-taking strategies that will help you pass the test and save time on the exam day.
The NCLEX CAT format
The NCLEX-RN employs a computerized adaptive testing (CAT) algorithm to evaluate candidates’ performance, rather than relying on a fixed passing score. As candidates answer questions, the testing software continuously assesses their performance and adjusts the difficulty of subsequent questions. Generally, candidates who answer questions correctly will face progressively more challenging items, while those who answer incorrectly will receive less difficult ones.
Unlike traditional exams, the NCLEX result is based on whether a candidate’s ability estimate falls above or below the established passing standard, rather than simply counting the number of questions answered correctly. Both the difficulty of the questions and the candidate’s performance on those questions are taken into account.
| Exam | Intended for | Format | Question count | Exam length | Content |
|---|---|---|---|---|---|
| NCLEX-RN | Registered Nurses (RNs) | Computer adaptive test (CAT); multiple choice and multi-option questions (SATA, drop-down, etc.) | 85-150 | 5 hours | Covers clinical decision-making, treatment planning, and coordination with other medical professionals |
The exam automatically concludes when the testing system determines, with 95% confidence, that a candidate’s ability is either above or below the passing standard. If this determination cannot be made sooner, a candidate may receive up to 150 questions. However, many candidates find that their test is complete before reaching this maximum number of items. Test-takers usually find out if they’ve officially passed or failed within about six weeks of the exam date (often sooner), and candidates in the U.S. may be able to access their results earlier.
Is there a paper version of the NCLEX?
No, there is no paper version of the exam available. The CAT format is designed to adjust question difficulty in real time, while maintaining fairness and integrity across testing formats. While there is no physical version of the exam, accommodations such as screen magnification and auditory support are available upon advance request.
Do you get scratch paper on the NCLEX?
No, you do not receive traditional scratch paper when taking the NCLEX. Instead, you will be provided an erasable note board and marker for writing down notes, calculations, and other needs during your exam. Notes and other materials are strictly prohibited in the exam room.

Why does the NCLEX use CAT?
There are a few reasons why the NCSBN employs computer adaptive testing for the NCLEX:
- It’s more efficient: It allows test-takers who can answer easy questions quickly to move on to more challenging, heavily weighted items.
- It’s more accurate: It enables candidates to have a truly personalized testing experience that matches their ability level.
- It doesn’t automatically penalize you for getting something wrong: You may be flying through your test when you hit a bump in the road. The test adjusts the difficulty accordingly so you can get back on track.
- It’s more secure: Since candidates are all given different questions, test-takers are less likely to spoil what other candidates may see on their test.
The NCSBN, like other organizations, has used CAT technology for decades because of its reliability and fairness. A second grading check is always conducted before official results are released to ensure maximum precision.
What percent do I need to pass the NCLEX?
There is no strict percentage to pass the NCLEX. Instead, you must answer at least 85 questions and up to 150 questions, and your measured ability must land above the passing standard.
The passing standards for the NCLEX-RN and NCLEX-PN reflect the amount of nursing ability currently required to practice competently at the entry level. Because nursing practice changes over time, the NCSBN Board of Directors reevaluates the passing standards every three years during test plan reviews.
Time-saving tips for the NCLEX
The NCLEX-RN is both a test of skill and a test of stamina. The exam often lasts several hours and requires complex decision-making, simulating situations you may encounter in the field. Just like treating a patient in real life, NCLEX questions require multi-step processing and quick thinking.
Here are some time-saving tips:
- Read the question carefully and in its entirety the first time. Not reading carefully may cost you time (and points), as NCLEX wording can sometimes be purposefully misleading.
- Pace yourself, but don’t spend too much time on one question. You must answer each question in order and won’t be able to go back to previous ones, so use your time effectively.
- Tip: Get comfortable with the NCLEX digital interface by practicing with official and realistic third-party practice tests.
- Know the different question types (multiple choice, Select All That Apply (SATA), bow-tie, drop-down, etc.) before entering the testing room. Having a strong grasp of nursing and medical concepts is important, but understanding how different widgets and questions work is equally necessary.
- Study smart, but also study hard. The NCLEX-RN shows more difficult questions the more answers you get right, so be prepared for the content to get more challenging as you progress. On the bright side, more difficult questions are worth more, so answering many correctly in a row can make your testing experience faster.
On average, you’ll have about two minutes per question if you use the full five hours and answer all 150 items. Keep in mind, however, that different question types, like case study NCLEX Next Generation questions, may require more time and consideration. Answering a wide variety of mock NCLEX-RN questions will help reveal which formats and topics you need the most practice with.
The NCLEX doesn’t just ask about specific procedures out of context. It asks which procedure or procedures are appropriate in a given scenario, and why. So make sure your practice covers not only medical facts but also how you’d apply them to treat a patient in a real client interaction.

How do you know if you passed the NCLEX right away?
You cannot officially confirm that you have passed the NCLEX immediately. In the U.S., candidates can get unofficial results for $7.95 via Pearson’s NCLEX Quick Results Service, usually within 2 business days after testing. However, these preliminary reports do not serve as official certification that someone is a nurse.
What do my NCLEX results mean?
The score reports given to candidates who pass and those who fail are quite different. Candidates who pass usually receive a report certifying that they completed the NCLEX and can register as nurses in their state, though it offers limited feedback on their performance.
Candidates who fail receive a CPR (Candidate Performance Report), an individualized document that provides information on their performance across various aspects of the exam. This information is categorized by content area, allowing candidates to focus on the areas they missed when studying for a retake. Those who answered fewer than the minimum number of items receive an abbreviated CPR without diagnostic information.
Conclusion
The NCLEX is structured to accurately assess nursing candidates’ abilities and competencies before official licensure over the course of five hours, though many test-takers finish sooner. As you go through the 85 to 150 questions on the test, the exam software is also hard at work, constantly assessing your progress. Questions are presented in a more-or-less difficult pattern depending on your responses, offering well-prepared test-takers the chance to finish the exam in less time by answering more challenging but heavily weighted questions. By practicing with realistic NCLEX-RN simulators and reviewing nursing content, from complicated med-surg topics to bedside manner 101, you can enter the testing center ready to take on whatever the CAT testing software sends your way.
