Next Generation NCLEX (NGN):
What Changed & How CAT Works

Understanding the algorithm is critical — here's how it actually decides your result.

The Next Generation NCLEX (NGN) launched in April 2023 and represents the most significant change to nursing licensure exams in decades. If you're preparing for NCLEX-RN or NCLEX-PN, understanding what changed — and how the Computer Adaptive Test (CAT) algorithm makes decisions — is critical to your success.

What Is the Next Generation NCLEX?

The NGN was developed by the NCSBN (National Council of State Boards of Nursing) to better assess clinical judgment — not just content recall. The old NCLEX tested whether you knew facts; NGN tests whether you can think like a nurse in real clinical scenarios.

This is a fundamentally different cognitive challenge, and many candidates who prepared using older NCLEX materials are caught off-guard by the NGN format.

New Item Types in NGN

NGN introduced several new question formats that don't exist in the traditional NCLEX. Here's what they look like and what they test:

📊 Extended Multiple Response (EMR)

Select ALL that apply — but with partial credit scoring. Getting some correct and some wrong earns partial marks. Strategy: avoid guessing extra answers.

🖱️ Extended Drag & Drop

Match nursing interventions, conditions, or findings to categories. Tests your ability to prioritise and categorise clinical decisions.

📋 Matrix/Grid Questions

A grid with rows and columns where you check cells. Example: for each listed finding, indicate whether it requires follow-up or is expected. Partial credit applies.

🎯 Cloze (Drop-Down) / Bowtie

Fill in the blanks by selecting from drop-down menus embedded in a paragraph. The "Bowtie" format presents condition + interventions + parameters in a structured template.

📈 Trend Items

Shows a client's vitals or labs across multiple time points (trending data). You must identify clinical deterioration, improvement, or the need for intervention based on trend analysis.

How the CAT Algorithm Works

The Computer Adaptive Test doesn't give everyone the same questions. It adapts in real time based on your performance. Here's the mechanics:

1. Starting Point

All candidates begin at the same difficulty level. The CAT measures your ability relative to the passing standard throughout the exam.

2. Dynamic Adjustment

Answer correctly → next question gets harder. Answer incorrectly → next question gets easier. The algorithm is constantly recalculating your estimated ability level.

3. The Passing Decision

The exam ends when the algorithm has 95% confidence that your ability is clearly above OR clearly below the passing standard — or when you've hit the maximum question count.

4. NGN Scoring Change

NGN introduced a new passing standard based on a logit scale (0.00 logits for NCLEX-RN). Your clinical judgment score now also factors into the passing decision — not just content knowledge.

Question Count: What to Expect

85–145
NCLEX-RN Question Range
85–150
NCLEX-PN Question Range

Getting fewer questions does NOT mean you failed. It means the algorithm reached 95% confidence in your result — either way. Candidates who pass at 85 questions have demonstrated ability clearly above the passing standard.

Preparation Tips for NGN

  • Practice all new item type formats — standard NCLEX prep books are insufficient for NGN.
  • Focus on clinical judgment frameworks (NCSBN's Clinical Judgment Model).
  • Practice trend analysis: interpreting lab values and vitals across time points.
  • Use UWorld, ATI, or Kaplan NGN-specific question banks.
  • For partial credit items: only select answers you're confident about.
