Every NCLEX-RN and NCLEX-PN candidate answers at least 85 and at most 150 questions, within five hours that include all breaks. The exam is adaptive, so the computer decides where in that range you stop. Here is what is inside the minimum 85, why exams end at different lengths, and why the number you get says nothing about whether you passed.
The short answer
Under the 2026 NCLEX-RN and NCLEX-PN test plans (effective April 1, 2026, through March 31, 2029), the length rules are identical for both exams:
| Rule | NCLEX-RN | NCLEX-PN |
|---|---|---|
| Minimum questions | 85 | 85 |
| Maximum questions | 150 | 150 |
| Time limit | 5 hours, including all breaks | 5 hours, including all breaks |
| Unscored pretest questions | 15 | 15 |
| Clinical judgment case studies | 3 (6 questions each) | 3 (6 questions each) |
What is inside the minimum 85 questions
NCSBN's test plan breaks the minimum-length exam into three parts:
- 52 questions from the eight Client Needs content areas, in the test plan percentages (see the 2026 test plan breakdown).
- 18 questions that make up three clinical judgment case studies. Each case study is a set of six questions about one client, one for each step of NCSBN's Clinical Judgment Measurement Model: recognize cues, analyze cues, prioritize hypotheses, generate solutions, take action, and evaluate outcomes.
- 15 unscored pretest questions that NCSBN is trying out. They look exactly like scored questions, so you cannot tell which ones they are, and they do not count toward your result.
Clinical judgment is also tested with stand-alone questions (about 10% of the exam) outside the case studies. For what those question formats look like, see our guide to Next Generation NCLEX case studies and item types.
Why everyone gets a different number of questions
The NCLEX uses computerized adaptive testing (CAT). After every answer, the computer re-estimates your ability and picks the next question to match it. NCSBN says candidates usually get questions they have about a 50% chance of answering correctly, so a hard exam is a sign the test is working, not a sign you are failing.
Once you reach 85 questions, the exam stops as soon as the computer is 95% certain your ability is clearly above or clearly below the passing standard. If your ability is close to the standard, it keeps going, up to 150. The full rules are in how the NCLEX is scored.
Does the NCLEX shutting off at 85 mean you passed?
No. NCSBN states that the length of your exam is not an indication of a pass or fail result: you can pass or fail at any length. An exam that ends at 85 means the computer reached a confident decision early, in either direction. An exam that runs to 150 means your ability was near the passing standard, and the final decision is made on all your answers.
Pacing: how much time per question
- There is no time limit on any single question, but the five hours include every break.
- If you were to reach all 150 questions, five hours works out to an average of 2 minutes per question, breaks included. Case study questions usually take longer than stand-alone ones, so bank time on quicker items.
- You must answer each question to move on, and once you select Next you cannot go back and change it. If you are unsure, choose your best answer and keep going.
- Running out of time matters: if time expires before you answer the minimum 85, the result is a fail.
Is the NCLEX-PN shorter than the NCLEX-RN?
No. Both exams have the same 85 to 150 range, the same five hours, the same 15 pretest questions, and the same three case studies. They differ in content and passing standard; see NCLEX-RN vs NCLEX-PN.
Frequently asked questions
How many questions are on the NCLEX-RN?
Between 85 and 150. The minimum 85 include 52 content questions, 18 questions in three clinical judgment case studies, and 15 unscored pretest questions.
How many questions are on the NCLEX-PN?
The same as the NCLEX-RN: a minimum of 85 and a maximum of 150 questions within five hours.
If the NCLEX shuts off at 85 questions, did I pass?
Not necessarily. NCSBN says exam length is not an indication of a pass or fail result. Stopping at 85 means the computer was 95% certain your ability was clearly above or clearly below the passing standard.
How long is the NCLEX?
You have up to five hours, and that includes all breaks. Arrive at the test center at least 30 minutes before your appointment.
Are there unscored questions on the NCLEX?
Yes. Every exam has 15 unscored pretest questions. They look like scored questions and you cannot tell them apart.
How many case studies are on the NCLEX?
Three. Each case study has six questions about the same client, one for each step of the clinical judgment model.
Can you skip or go back on the NCLEX?
No. You must answer each question to continue, and you cannot return to a question after moving on.
