Nursing NCLEX Pass Probability Calculator

The NCLEX uses Computerized Adaptive Testing (CAT), which adjusts question difficulty based on your performance. The exam continues until it can determine with 95% confidence whether you are above or below the passing standard. If the system reaches that confidence level early, the exam may end at the minimum number of questions (85 for NCLEX-RN). Strong, consistent performance in the higher difficulty bracket can end the exam sooner.

Yes, receiving all 145 questions (the maximum for NCLEX-RN as of 2023 Next Generation NCLEX) does not mean you failed. It simply means the CAT algorithm needed more questions to confidently determine your competency level. Many candidates who answered all questions still pass — it depends on the difficulty level maintained throughout the exam.

Not necessarily. The minimum number of questions is 85 for NCLEX-RN, but the exam can end at any point once confidence is established. Some pass at 85 questions, others at 100, 120, or even at the maximum. The number of questions alone is not a reliable indicator of passing or failing.

Yes. If the CAT algorithm determines with 95% confidence that you are performing below the passing standard by the minimum question count, the exam will end at 85 questions with a failing result. This is why some candidates who finished quickly find they did not pass.

ATI benchmarks generally suggest that a score of 67–69% or above on the ATI Comprehensive Predictor correlates with a 95–99% probability of passing NCLEX. Scores below 58–60% may indicate the need for additional preparation. Your program may set its own ATI benchmark threshold.

Most candidates can access unofficial results through the Quick Results Service (available in participating states) approximately 48 hours after testing for a small fee. Official results are typically posted to your state board of nursing's website within 1–6 weeks. The Pearson Vue Trick (PVT) is an unofficial method many candidates use, though it is not guaranteed to be accurate.

If you fail the NCLEX, you will receive a Candidate Performance Report (CPR) outlining your performance in each content area. You must wait a minimum of 45 days before retesting (in most states). There is no limit on the number of retake attempts, though some states have their own rules. Most candidates who retake the exam after focused remediation are successful.

UWorld is widely regarded as one of the strongest NCLEX predictors. Research and anecdotal data suggest that candidates averaging above 55–60% on UWorld have strong pass rates. UWorld's own readiness assessments (Self-Assessment 1 and 2) also provide a predicted probability of passing. However, no single prep tool guarantees results — consistent performance across multiple resources is the best predictor.
