Q: What are the 3 NCLEX pass or fail decision rules?
A: The NCLEX uses a Computerized Adaptive Testing (CAT) system with three core "stopping rules." The exam continues until one of these rules is met, at which point a pass/fail decision is finalized. They are:
- The 95% Confidence Interval Rule (Most Common): The exam stops when the computer is 95% statistically confident that your ability is either clearly above or clearly below the passing standard. This can happen at the minimum of 85 questions, the maximum of 150, or anywhere in between.
- The Maximum-Length Exam Rule: If the computer cannot reach 95% confidence by question 150, it stops and makes a final ability estimate using all 150 questions. If your final ability estimate is at or above the passing standard, you pass; if below, you fail.
- The Run-Out-Of-Time (ROOT) Rule: If you do not finish all required questions within the 5-hour time limit, your result is scored differently. If you answered the minimum required questions (85) and your final ability estimate is above the passing standard, you pass. If you did not reach 85 questions, or your ability at the last answered question is below the standard, you fail. Note: Unanswered questions are counted as incorrect.
Q: Which rule is most commonly triggered?
A: The vast majority of exams (estimated over 80%) end by the 95% Confidence Rule before reaching 150 questions. The "Max-Length" and "Run-Out-Of-Time" rules are less common.
Q: How does the "Run-Out-Of-Time" rule affect my strategy?
A: It underscores the critical importance of time management. You must practice pacing to ensure you can thoughtfully answer the minimum 85 questions. Do not spend excessive time on any single question. If you find yourself running out of time, make sure to provide an answer for every question, as leaving them blank guarantees they are marked wrong.
Q: Can I know which rule stopped my exam?
A: No. The official result (Pass/Fail) does not specify which stopping rule was applied. You only know your final result and the number of questions you answered. The specific rule is internal to the CAT algorithm.
Q: How should I prepare to ensure the 95% Confidence Rule works in my favor?
A: Your goal is to demonstrate clear competency early. This requires:
- Strong, Consistent Knowledge: Eliminate major content gaps.
- Mastery of Clinical Judgment: Especially for Next Generation NCLEX (NGN) items.
- Practice Under Real Conditions: Take full-length, CAT-style practice exams to build the accuracy and stamina needed to pull your ability estimate clearly above the passing standard.
