What this is

A computer adaptive test built the way NCSBN describes the NCLEX: a Rasch ability model, items chosen for the information they give about you, the 2023 test-plan content balance, partial credit on Next Generation items, and the same stopping rules (85 minimum, 150 maximum, 5 hours, a 95% confidence decision). It ends with a pass/fail call and a concept-by-concept map of where you stand.

Before you begin

• Minimum 85 items, maximum 150 items, 5-hour limit. Content follows the 2026 NCLEX-RN test plan (effective April 1, 2026).
• Five unfolding case studies of six items each are built into the exam. Each case walks the six steps of the NCSBN Clinical Judgment Measurement Model: recognize cues, analyze cues, prioritize hypotheses, generate solutions, take action, evaluate outcomes.
• After the minimum, the test ends as soon as it is 95% certain your ability is above or below the passing standard.
• At the maximum, you pass if your final estimate is above the standard. If time runs out, the same rule applies to your estimate at that moment.
• You cannot skip or go back. Each stand-alone item is chosen from your last answers: a miss is probed again inside the same concept cluster before the test moves on. Items you have already answered on this device are not shown again on a later attempt.

Ability estimate

Rasch model: the chance a candidate of ability θ answers an item of difficulty b correctly is P = 1 / (1 + e^−(θ−b)). After every answer the engine recomputes θ as the expected value of the posterior over a −4…4 grid with a N(0,1) prior (EAP), and the standard error as the posterior spread. EAP never diverges on a run of all-correct or all-wrong answers, which maximum likelihood does.

Stopping rules (NCSBN)

• 95% confidence interval rule. From item 85 on: if θ − 1.96·SE > standard → pass; if θ + 1.96·SE < standard → fail. Otherwise keep going.
• Maximum-length rule. At item 150 the interval is ignored; θ above the standard passes.
• Run-out-of-time rule. At 5 hours, same as maximum-length, using θ at that moment, provided the minimum has been reached.

Next-item selection

Every unused item gets a score and the top score is administered. The score is the product of four factors:

1. Information at current θ: P(1−P). Items near the candidate's level tell the engine the most.
2. Content balance: each client-needs category has a target share from the test plan. Categories running behind their share are boosted; categories past their ceiling are suppressed.
3. Knowledge chaining: after a miss, items in the same concept cluster at or just below the current θ are boosted (a confirmation probe, up to two per cluster). After a hit, items in clusters the concept graph marks as related are boosted at a slightly higher difficulty, and the same cluster is discouraged so the test moves on.
4. Calibration preference: items with a calibrated difficulty (Epsilon Form 1 and Form 2) are favored 1.6:1 over items whose difficulty is still an author estimate, so the supplementary banks mostly fill chaining and content-balance needs.
5. Exposure: a cluster is not administered three times in a row, and one-in-six items is a pure information pick regardless of chaining, so a candidate cannot steer the test.

NGN items are scored with NCSBN's partial-credit rules: SATA uses +/− scoring (each correct selection +1, each incorrect selection −1, floor at zero); matrix, cloze, ordered-response and bow-tie items earn one point per correct element; multiple choice and calculations are all-or-nothing. The fraction earned feeds the ability estimate directly (a 3-of-5 bow-tie contributes 60% of a correct response and 40% of an incorrect one), which approximates the polytomous model NCSBN uses. For chaining and the knowledge map, 50% credit or more counts as a hit.

Case studies. Five unfolding case studies (six items each, one per step of the NCSBN Clinical Judgment Measurement Model) are scheduled at fixed points inside the minimum-length exam, spaced so that stand-alone content items fill the gaps between them. Case items feed the ability estimate with the same partial-credit rules, but they are counted independently of the client-needs percentages and do not steer the chaining, exactly as NCSBN describes for the 2026 test plan (52 content items + 18 case-study items + 15 pretest items in an 85-item exam; this product runs five cases instead of three and has no unscored pretest items). The highlight format uses +/− scoring like SATA.

Repeat attempts. Items and cases administered on an earlier attempt in this browser are excluded from later attempts (NCSBN: a repeat candidate does not see the same item again). If fewer than about 160 fresh items remain, seen items are allowed back at a heavy penalty rather than letting the pool run dry.

The report then classifies each cluster: mastered (every probe correct, two or more), gap (two or more misses, or a miss on an item easier than the final θ), slip (one miss, then correct on the follow-up probe), or thin (one data point).
