NCLEX Item Types and Partial Credit: Plus/Minus, Zero/One, and Rationale Scoring
NCLEX-RN study guide · Published December 2, 2026
Direct answer: The NCLEX uses multiple item formats, and NCSBN currently applies one of three scoring rules to an item: plus/minus, zero/one, or rationale scoring. Plus/minus rewards correct selections and subtracts for incorrect selections without allowing a negative item or scoring-group total. Zero/one gives each fixed response unit either 1 point for correct or 0 for incorrect, with multipoint units summed when applicable. Rationale scoring evaluates tightly linked response elements: a dyad earns 1 point only when both elements are correct, while a triad can earn up to 2 points and allows limited partial credit when the first element is correct with either the second or third.

What item types can appear on the NCLEX?
The official 2026 NCLEX-RN Test Plan says candidates may receive stand-alone items, case studies, and items written in multiple formats; any format may include charts, tables, or graphics. The plan directs candidates to the NCLEX Candidate Tutorial for detailed format examples. The official NCLEX Prepare page also links the current Sample Pack, Exam Preview, and Pearson Candidate Tutorial so candidates can practice the interface before exam day.
NCSBN's 2025 Item Scoring presentation, which remains the current scoring-method reference cited by NCSBN resources, catalogs these response types for scoring purposes:
| Item format | What you do | Scoring family shown by NCSBN |
|---|---|---|
| Multiple choice | Choose one option. | Zero/one |
| Calculation | Enter a numeric response. | Zero/one |
| Ordered response | Place responses in the required order. | Zero/one |
| Matrix multiple choice | Choose one option in each row. | Zero/one |
| Multiple response — Select N | Select the stated number of options. | Zero/one |
| Drop-down cloze / drag-and-drop cloze | Complete fixed blanks or targets. | Zero/one |
| Drop-down table | Make one selection in each required cell. | Zero/one |
| Bow-tie | Complete the required categories in the item. | Zero/one |
| Multiple response — Select All That Apply | Choose every option you judge to be correct. | Plus/minus |
| Highlight text / highlight table | Select relevant words, phrases, or table cells. | Plus/minus |
| Matrix multiple response | Select one or more responses within matrix columns. | Plus/minus |
| Multiple response grouping | Select applicable responses within each group. | Plus/minus |
| Drop-down rationale / drag-and-drop rationale | Complete linked answer-and-reason relationships. | Rationale |
This is a format catalog, not a prediction of what proportion of your exam will use each format. NCSBN's NCLEX FAQ explicitly says there is no established percentage of item formats administered to candidates.
How the three official partial-credit methods work
1. Plus/minus scoring
Under plus/minus scoring, NCSBN awards +1 for a correct selection and −1 for an incorrect selection. The score cannot fall below zero. For grouped formats, NCSBN applies the rule within the relevant column or grouping before adding the nonnegative group scores.
Independent KOTC teaching example: Imagine a Select All That Apply item with three correct options: A, C, and D. If a learner selects A, C, and E, the two correct selections contribute +2 and the incorrect E contributes −1, for a raw item score of 1. If the learner selected only E, the mathematical difference would be negative, but the scored result is floored at zero. This example illustrates the rule; it is not an actual NCLEX item.
Practical implication: Do not select an option merely because it is vaguely plausible. On a plus/minus item, an unsupported extra selection can offset credit you earned elsewhere.
2. Zero/one scoring
Zero/one is the classic scoring rule: a scoring unit receives 1 point when correct and 0 when incorrect. The important nuance is that a multipoint item can contain several fixed scoring units. NCSBN's current presentation gives cloze and drop-down examples in which each required target or drop-down is scored 0 or 1 and the units are summed.
Independent KOTC teaching example: Consider a three-row drop-down table. If the learner answers rows 1 and 3 correctly but row 2 incorrectly, those three fixed response units could contribute 1 + 0 + 1 = 2 raw points under the zero/one rule. The lesson is not “one mistake makes the whole multipoint item zero”; it is “each fixed unit is either correct or incorrect according to that item's scoring design.”
Zero/one also applies to item types where a fixed number of responses is required, including Select N. Follow the number requested by the interface rather than treating it like open-ended SATA.
3. Rationale scoring
Rationale scoring is used when the item tests closely connected information and the relationship between the elements matters. NCSBN describes two structures. A dyad links two elements, such as “X because of Y,” and earns 1 point only if both elements are correct. A triad links three elements, such as “X because of Y and Z,” and is worth up to 2 points.
For a triad, NCSBN says 1 point of partial credit can be earned when the first and second elements are correct or when the first and third elements are correct. The first element must be correct to earn any credit.
Independent KOTC teaching example: Suppose an item asks you to complete “The client is most likely experiencing [X], as evidenced by [Y] and [Z].” If X is correct and Y is correct but Z is not, that triad demonstrates one correct evidence relationship and can earn 1 of the 2 available raw points under the rationale rule. If X is wrong, correctly identifying Y alone does not earn rationale credit. This is a teaching example, not an NCSBN exam question.
A better way to practice item formats
The scoring rules are useful because they change how you should review mistakes. They should not become a second exam you try to calculate in your head while answering. Use the official tutorial to learn the controls, then use practice questions to build a repeatable decision process.
- First identify the interaction: one choice, fixed number of choices, open multiple response, highlight, matrix, cloze, or linked rationale.
- Read the selection instruction literally: “select N” and “select all that apply” are not the same task.
- For plus/minus formats, require evidence for every selected option: extra guessing can cost a point.
- For zero/one multipoint formats, treat each required field as its own decision: do not let uncertainty on one field contaminate the rest.
- For rationale formats, test the relationship: ask whether the lead conclusion is correct and whether each supporting element actually justifies it.
- After practice, review reasoning rather than raw points alone: identify whether the miss came from nursing knowledge, cue interpretation, over-selection, or a format mistake.
This checklist is King of the Curve learning guidance, not an NCSBN test-taking rule.

FAQ
Does every NCLEX item use partial credit?
No. The 2026 Test Plan says partial credit is used for items for which more than one key exists. Other items or scoring units may simply receive 1 for correct and 0 for incorrect.
Is zero/one scoring always all-or-nothing for the entire item?
No. NCSBN's current scoring examples show multipoint formats in which several fixed response units are each scored 0 or 1 and then summed.
Can an incorrect selection reduce credit on a plus/minus item?
Yes. NCSBN's plus/minus rule gives +1 for a correct selection and −1 for an incorrect selection, with negative totals truncated to zero at the applicable scoring level.
Can a triad rationale item earn partial credit?
Yes. A triad is worth up to 2 points. One point can be earned when the first and second elements are correct or when the first and third elements are correct; the first element must be correct for any credit.
Can I add up partial-credit points to know whether I passed?
No. NCSBN uses a psychometric model to transform item scores onto the NCLEX scale. Candidate-facing raw point addition is not a valid way to calculate the final NCLEX result.
