Computer-adaptive testing
Every item has a known difficulty. After each answer, the exam updates its estimate of your ability and picks the next item to be one you have about an even chance of answering correctly. Answer correctly and the next item is harder; answer incorrectly and it is easier. That is why the exam feels hard to almost everyone: it is designed to.
Because of this, the share of items you get right says little. Two candidates can both answer about half their items correctly and get different results, because one was answering much harder items.
Length and timing
- 85 to 150 items. 15 are unscored pretest items mixed in with the rest; you cannot tell which ones they are.
- 3 case studies of six items each are part of every exam.
- Up to 5 hours, including the tutorial and every break.
When the exam stops
- The confidence rule. Once you have answered the minimum, the exam stops as soon as it is 95% confident your ability is clearly above or clearly below the passing standard.
- The maximum-length rule. If you reach 150 items, your final ability estimate decides the result.
- The run-out-of-time rule. If time runs out before you reach the minimum, the result is a fail. If you have reached the minimum, your answers so far decide it.
The practical lesson: keep a steady pace. Spending ten minutes on one item costs more than getting it wrong.
Partial credit
Next Generation items can earn partial credit: a point for each correct choice, with points taken away for wrong choices on select-all items. See each item type with an example.
Results
Your nursing regulatory body sends the official result, usually within about six weeks. Many boards also offer unofficial quick results, often within two business days. If you need to retest, the usual waiting period is 45 days, though your board sets the rules.
Common questions
How many questions are on the NCLEX-RN? Between 85 and 150. 15 of them are unscored pretest items, so between 70 and 135 count toward your result.
Does stopping at 85 questions mean I passed? No. The exam stops at the minimum when it is confident of the result either way. Candidates pass and fail at every length.
How long is the NCLEX? Up to 5 hours, including the tutorial, sample items and all breaks.
Is there a percentage score? No. The result is pass or fail. The exam measures whether your ability is above the passing standard, not what percentage of items you got right.
