NGN Partial Credit Scoring: 0/1, Plus/Minus, and Rationale Scoring in Practice
The NCLEX uses partial credit for items with more than one correct answer, applying three named methods: plus/minus (a point for each correct response, minus a point for each incorrect one, floored at zero), zero/one (points for correct responses with no penalty for wrong ones), and rationale scoring (all-or-nothing credit for linked pairs). NCSBN does not publish which method applies to which item type, so the rule that works under all three is to select what you can clinically justify and leave what you cannot.
This is the most consequential thing most candidates never learn, and it is also the place where you should be most skeptical of what you read — including some of what you will read here, which is why the boundaries are marked.
What NCSBN publishes
The 2026 test plan, the candidate bulletin, and the NCLEX FAQ all carry the same sentence:
“NCLEX items have multiple item formats. There is partial credit scoring for items for which more than one key exists. There are three methods for scoring items for partial credit: plus/minus, zero/one and rationale scoring.”
So: three methods, named. Partial credit applies to items with more than one correct answer.
How each method works is explained in NCSBN’s own presentation materials:
Plus/minus scoring. “Candidates receive a point for correct responses and lose a point for incorrect responses.” A negative overall score on the item is rounded up to zero — you cannot go below zero on a single item.
Zero/one scoring. “Candidates receive a point for correct responses but do not lose points for incorrect responses.”
Rationale scoring. “Candidates receive ‘all or nothing’ credit for paired information within an item.” NCSBN illustrates this with paired stems — the nurse should question the order for X because of Y, or the client is at highest risk of X as evidenced by Y. Both halves must be correct to earn the point.
What NCSBN does not publish: which method applies to which item type.
NCSBN has a dedicated presentation on item scoring, but it sits behind a login. The public materials name the three methods, explain the mechanics, and stop. Every published chart mapping item types to scoring methods is inference by the person who made it.
That matters, because the strategy differs by method — and you will not know which one you are facing.
Why partial credit exists at all
Older NCLEX scoring was all-or-nothing. A select-all-that-apply item with five options and four correct answers gave you nothing for getting three right.
NCSBN’s stated reasoning for the change: the NCLEX “is now the first licensure examination to extend the CAT methodology to polytomously scored (partial credit) items, which increases the precision of measurement and allows for better differentiation in candidates’ understanding than simply placing their responses in ‘all correct’ or ‘all incorrect’ groupings.”
In plain terms: a candidate who gets four of five right knows more than a candidate who gets one of five right, and the exam now measures that difference instead of scoring both as zero.
This is good news for you. Under the old system, near-misses were worth nothing. Now they are worth something.
The strategic problem
Here is the honest difficulty.
Under zero/one scoring, wrong selections are free. If you are uncertain, select. There is no downside — a wrong pick costs nothing and a right one earns a point. Selecting everything would be optimal if this were the only method.
Under plus/minus scoring, wrong selections actively subtract. Selecting everything is a terrible strategy. Uncertain selections cost you real points.
Opposite strategies. And you cannot tell which method is running, because the item does not tell you and NCSBN does not publish the mapping.
The rule that works under either method
Select what you can justify. Do not select what you cannot.
The test is whether you can state a clinical reason. If you can say “this belongs because the patient’s potassium is 6.2 and that causes cardiac dysrhythmias,” select it. If the best you can say is “it might be one of them,” leave it.
Why this works under both:
Under zero/one, justified selections are all correct-or-close and earn points. You leave a few possible points on the table by not guessing wildly — a small cost.
Under plus/minus, you avoid the penalties that wild guessing would incur — a large benefit.
The expected value across the uncertainty favors discipline. And it has a second advantage: it is the same standard you will be held to in practice, where “I selected it because it might be relevant” is not a defensible rationale.
What this means item by item
Select-all-that-apply and extended multiple response. Evaluate each option independently as true or false against the stem. Do not aim for a target number. Some items have two correct answers, some have five.
Matrix items. Each row is its own question. Answer every row — a blank row cannot earn credit under any method.
Drag and drop and highlighting. Same discipline. Place or select what you can justify; leave what you cannot.
Paired-reasoning items — the rationale-scoring shape. When an item asks you to complete a sentence with two linked blanks, both halves must be right. Solve the harder half first, usually the condition or the cause, then choose the evidence or reasoning that matches. Do not select a compelling-sounding second half that does not actually connect to your first half — a mismatched pair earns nothing.
Three things to stop believing
“Guessing is free.” True under zero/one, false under plus/minus, and you cannot tell which you are in.
“You have to get the whole item right or you get nothing.” This was true before partial credit. It is not true now. Answer the parts you know.
“Item type X is always scored using method Y.” Not published by NCSBN. If a resource states this as fact, that tells you something about how carefully it distinguishes sourced information from inference.
The practical summary
Three methods exist. Plus/minus penalizes wrong answers and floors at zero. Zero/one does not penalize. Rationale scoring is all-or-nothing on linked pairs.
You will not know which is being applied.
So answer every part of every item, select what you can clinically justify, leave what you cannot, and for paired items make sure both halves fit together.
That is a strategy that holds up under any of the three — and it is just careful nursing reasoning, which is what the exam is measuring in the first place.

Frequently asked questions
Common follow-up questions on The 2026 Test Plan & Next Gen NCLEX.
What are the three partial-credit scoring methods?
Plus/minus scoring gives a point for each correct response and subtracts a point for each incorrect one, with the item score never falling below zero. Zero/one scoring gives a point for each correct response but does not subtract for wrong ones. Rationale scoring gives all-or-nothing credit for paired information, where both halves of a linked statement must be correct to earn the point.
Which scoring method applies to which item type?
NCSBN does not publish which method applies to which item type. The public materials name the three methods and explain the mechanics, then stop. Every published chart mapping item types to scoring methods is inference by the person who made it, so you cannot know which method you are facing on any given item.
Should I guess on select-all items to be safe?
It depends on a method you cannot see. Under zero/one scoring wrong selections are free, so guessing helps; under plus/minus scoring wrong selections actively subtract, so guessing hurts. Because the strategies are opposite and you cannot tell which is running, the disciplined rule of selecting only what you can justify holds up best across the uncertainty.
Is it still all-or-nothing if I miss part of an item?
No, not anymore. Older NCLEX scoring was all-or-nothing, so a select-all item with four correct answers gave you nothing for getting three right. Partial credit now measures the difference, so a candidate who gets four of five right earns more than one who gets one of five right. Answer the parts you know.
How do I handle paired-reasoning (rationale-scoring) items?
When an item asks you to complete a sentence with two linked blanks, both halves must be right to earn the point. Solve the harder half first (usually the condition or the cause) then choose the evidence or reasoning that matches it. Do not select a compelling-sounding second half that does not actually connect to your first half, because a mismatched pair earns nothing.
