- The NLN PAX was retired after May 31, 2024 and replaced by the NLN Nursing Entrance Exam (NEX) on February 11, 2024.
- The exam has 163 total items (145 scored, 18 pilot) across Verbal, Mathematics, and Science in three 60-minute sections.
- Science is the heaviest section at 38% of the scored test, with Biology alone worth 14%.
- Scores are percentile ranks on a 0-300 composite scale, not a fixed pass/fail cutoff - each program sets its own minimum.
What Is the NLN PAX / NEX?
The NLN PAX is the nursing school entrance exam historically administered by the National League for Nursing (NLN) through its Assessment Services division. It was designed to measure whether an applicant to a registered nursing (RN) or licensed practical/vocational nursing (LPN/VN) program has the verbal, mathematical, and science reasoning skills needed to succeed in coursework. If you're researching "what is NLN PAX," you're really asking about the entrance exam nursing programs use to screen applicants before they're admitted to a program - not a professional license or a post-graduation certification.
Today, this exam is officially called the Nursing Entrance Exam (NEX), but because thousands of nursing programs and applicants still use the older name, "NLN PAX" and "NEX" refer to the same current exam in practice. This site's NLN PAX Certification overview and our NLN PAX Meaning guide both unpack this naming history in more detail if you want the full background.
Why the Name Changed From PAX to NEX
The National League for Nursing retired the PAX after May 31, 2024. Its replacement, the NEX, launched February 11, 2024, so there was a brief overlap window during which both exams existed. Nursing programs that still list "NLN PAX" on their admissions pages are, in nearly all cases, now administering the NEX under the old, more familiar name. If you took the PAX before June 2024, don't worry - many programs still accept those scores, so your prior score report likely still has value during your application window.
The content also changed with the transition. Physics and extended geometry topics were dropped, and a new Data and Information area was added inside Mathematics. This matters for anyone studying from older materials: outdated question banks may still drill you on physics concepts that no longer appear on the current exam, while under-covering data interpretation, which now counts toward your Math score.
For a side-by-side look at exactly what's tested now versus what used to be tested, see our NLN PAX Exam Domains 2026: Complete Guide to All 11 Content Areas.
Exam Format and Question Style
The NLN PAX/NEX is delivered as a Linear-On-The-Fly Test (LOFT), meaning the platform builds a unique form for each test-taker from a blueprint-controlled item pool. No two candidates necessarily see the identical set of questions, but every form is statistically comparable in difficulty and content coverage. You'll sit for a single proctored session lasting three hours total, either at an approved institutional testing center on campus or virtually through a live Proctor360 proctor.
The exam is broken into three back-to-back 60-minute subject tests:
- Verbal: 50 scored items plus 8 pilot items
- Mathematics: 40 scored items plus 5 pilot items
- Science: 55 scored items plus 5 pilot items
That's 163 total items, 145 of which are scored and 18 of which are unscored pilot questions used by the NLN to test future exam content. Every item is four-option multiple choice. There's no penalty for guessing, but an unanswered item is scored as incorrect - so finishing every item you can within the hour matters more than skipping ones you're unsure about. A basic four-function calculator is built into the testing interface for the Mathematics section, so you won't need (or be permitted) to bring your own.
Key Takeaway
Because unanswered items count against you and there's no guessing penalty, always select an answer for every question before time expires on each 60-minute section, even if it's a guess.
The 11 Content Domains
Understanding how the 145 scored items are distributed across content areas is the single most useful thing you can do before you start studying, because it tells you exactly where your time investment pays off. Science carries the most weight overall at 38% of the scored test, followed by Verbal at 34% and Mathematics at 28%.
Verbal (34% combined)
Split evenly between Word Knowledge (17%) and Reading Comprehension (17%). Word Knowledge tests vocabulary in isolation, often including medical and everyday terms, while Reading Comprehension asks you to interpret short passages.
- Build vocabulary through active reading, not flashcards alone
- Practice pulling main ideas and inferences from unfamiliar passages under time pressure
Mathematics (28% combined)
Covers Numbers and Operations (8%), Measurement (10%), Algebra (5%), and Data and Information (5%). Notice Measurement carries the most weight in this section - conversions, ratios, and dosage-style calculations deserve extra attention.
- Master unit conversions and ratio/proportion problems, since Measurement is the largest math domain
- Practice reading tables, charts, and graphs for the newer Data and Information area
Science (38% combined)
The largest section overall, made up of Biology (14%), Human Anatomy (8%), Human Physiology (8%), Chemistry (3%), and Health (6%). Biology alone is worth more than any single Math domain.
- Prioritize cell biology, genetics, and basic biological systems given Biology's 14% weight
- Review major body systems for the combined 16% covered by Anatomy and Physiology
- Don't neglect Chemistry and Health - smaller weights still add up across 55 items

| Section | Scored Items | Pilot Items | % of Scored Test |
|---|---|---|---|
| Verbal | 50 | 8 | 34% |
| Mathematics | 40 | 5 | 28% |
| Science | 55 | 5 | 38% |
| Total | 145 | 18 | 100% |
How Scoring Actually Works
One of the most misunderstood parts of the NLN PAX is scoring. The NLN does not set a universal passing or failing mark. Instead, scores are norm-referenced percentile ranks, meaning your performance is compared to other test-takers rather than measured against a fixed cutoff. Since November 1, 2025, the NLN reports these percentile ranks against two separate reference groups: one for RN applicants and one for LPN/VN applicants.
Your composite score is the sum of your three subject percentile ranks, producing a scale from 0 to 300. The 50th percentile equals a composite of 145 for RN applicants and 143 for LPN/VN applicants. Because there's no NLN-mandated passing score, each nursing program independently decides what composite or subject-level minimum it will accept for admission - which means the "passing score" you need depends entirely on the specific program you're applying to.
Shortly after testing, you'll receive a score report along with a diagnostic Coaching Report. This breaks your performance out by content area and by four reasoning dimensions: Knowledge, Application, Interpretation, and Logic and Reasoning. If you retest, the NLN requires a 30-day wait between attempts unless your specific school sets a different frequency, and many programs also cap the total number of lifetime attempts. For exact figures and how programs typically interpret them, see NLN PAX Passing Score 2026: Exactly What You Need to Pass.
Registration, Delivery, and Fees
You can take the exam in one of two ways: on campus at an approved institutional testing center, or virtually through a live Proctor360 proctor from home or another private location. Both formats deliver the same three-hour, 163-item exam built by the same LOFT engine.
Effective March 1, 2026, NLN pricing is:
- $59.00 for school-paid, on-campus administration
- $80.00 for virtual administration via Proctor360
These figures are before any additional institutional proctor or administration fee your school may add on top. If you're scheduling a virtual session on short notice, Proctor360 adds a $30 fee for on-demand scheduling inside 48 hours or for rescheduling inside 24 hours of your appointment. The NLN also operates a strict no-refund policy, so double-check your test date, location, and format before you pay. A full cost breakdown, including how institutional fees can stack on top of NLN pricing, is covered in NLN PAX Certification Cost 2026: Complete Pricing Breakdown.
Eligibility is straightforward: you need a high school diploma or GED to sit for the exam. There's no age minimum, prior coursework requirement, or professional license needed just to register. Our NLN PAX Requirements 2026 page walks through eligibility and how retake rules interact with individual school policies.

Who Requires It and Why
Nursing programs - both RN-track and LPN/VN-track - use the NLN PAX/NEX as a pre-admission screening tool to compare applicants on a consistent, standardized basis before granting a seat in a competitive program. Because class sizes are limited and clinical placements are expensive to run, schools rely on a norm-referenced score to help rank a large applicant pool fairly, alongside GPA, prerequisite coursework, and interviews.
This means the exam itself isn't a job qualification or a workplace credential - it's a gate you pass through on the way into nursing education, which then leads to the coursework, clinicals, and licensing exams that actually qualify you to practice.

How to Prepare by Domain Weight
Because Science is worth more of your composite than either Verbal or Mathematics, and Biology alone outweighs any individual Math domain, your study schedule should be shaped by the domain percentages rather than by how comfortable each subject feels. A candidate who is strong in algebra but weak in Biology is better off spending more hours on Biology, simply because it's worth more points.
Science Foundations
- Review Biology (14%), the single heaviest domain on the exam
- Cover Human Anatomy and Human Physiology (8% each) together since they overlap heavily
Verbal Sharpening
- Build vocabulary for Word Knowledge (17%) using medical and general terms
- Practice timed passages for Reading Comprehension (17%)
Mathematics and Remaining Science
- Drill Measurement (10%) conversions and ratio problems, the largest math domain
- Cover Numbers and Operations, Algebra, and Data and Information
- Finish Chemistry (3%) and Health (6%) review
Full-Length Practice
- Take timed, full-length practice exams to simulate the three-hour LOFT format
- Review missed items by the four Coaching Report dimensions: Knowledge, Application, Interpretation, Logic and Reasoning
This kind of weighted scheduling is discussed step by step, with more granular weekly tasks, in our NLN PAX Study Guide 2026: How to Pass on Your First Attempt. If you're still deciding how much runway to give yourself, How Hard Is the NLN PAX Exam? Complete Difficulty Guide 2026 breaks down what actually makes the exam challenging section by section. And for last-minute review the night before test day, our NLN PAX Cheat Sheet 2026 condenses the must-know facts into one page.
Whichever pace you choose, practicing under real timed conditions matters more for this exam than for many others, since each subject test is a hard 60-minute block with no extra time carried over. You can build that timing discipline directly on our practice test platform, which mirrors the three-section, four-option multiple-choice format you'll see on test day. Running a few full simulations on the practice site before you register is one of the most direct ways to confirm you're pacing correctly across all three sections.
