How the NCLEX-RN is Scored
Last reviewed September 13, 2026.
The NCLEX is not passed by reaching a universal percentage of correct answers. Its computerized adaptive testing system estimates a candidate’s ability using responses and item difficulty, then compares that estimate with a passing standard. A practice-bank percentage therefore should not be presented as an official NCLEX passing threshold.
How the result is determined
NCSBN describes three decision rules. The most common uses a 95% confidence criterion to determine whether ability is above or below the passing standard. At maximum exam length, the final ability estimate determines the result. When time expires before a decision, answering fewer than the required minimum results in failure; after the minimum, the final ability estimate is used. An estimate at or above the standard passes under the latter two rules.

Current exam length
NCSBN states that the NCLEX-RN and NCLEX-PN contain 85–150 items and allow up to five hours, including the introductory screen and all breaks. The number of questions alone is not a reliable way to infer the result. Check the official guidance again before your test date.
Partial credit
The exam is not accurately described as using only all-or-nothing scoring. NCSBN identifies partial-credit scoring for multiple-response select-all-that-apply items and describes current clinical-judgment item formats. Learn the directions for each item rather than assuming that every response format behaves the same way.

Planning your preparation
Use the current official test plan and preparation materials alongside your program’s guidance. Do not treat a fixed number of study hours or one practice score as a guarantee. A useful academic review session should identify what you cannot yet explain and help you plan the next practice step.
