NCLEX-RN vs. NCLEX-PN: Content, Difficulty, and Scope Differences
The NCLEX-RN and NCLEX-PN share the same structure, 85 to 150 items over five hours with 15 unscored pretest items and 18 case study items, but differ where it matters: the RN passing standard is 0.00 logits versus -0.18 for the PN, and the RN exam weights pharmacology (with parenteral therapy) and physiological adaptation more heavily. The lower PN standard reflects a different scope of practice, not a weaker version of the same job.
The two exams look almost identical on paper and differ in exactly the ways that matter. Here is a precise comparison, using the test plans effective April 1, 2026.
What is identical
Both exams share the same structure:
- 85 to 150 items, variable-length computerized adaptive testing
- Five hours total, including all breaks
- 15 unscored pretest items on every exam
- 18 clinical judgment case study items — three case studies of six items each — on a minimum-length exam
- Same test center procedures, same ID rules, same break structure
- Test plans effective April 1, 2026 through March 31, 2029
A candidate walking into either exam has the same day, the same interface, and the same rules.
What differs: the passing standard
| NCLEX-RN | NCLEX-PN | |
|---|---|---|
| Passing standard | 0.00 logits | −0.18 logits |
| Effective through | March 31, 2029 | March 31, 2029 |
The PN standard is lower on the logit scale. This is not a statement that PN candidates are held to a weaker version of the same job — it reflects a different scope of practice with a different set of entry-level expectations. Each exam is calibrated against its own practice analysis.
What differs: the content distribution
Both exams use eight client-needs categories. The category names and weights differ.
| Category | NCLEX-RN | NCLEX-PN |
|---|---|---|
| Management of Care (RN) / Coordinated Care (PN) | 15–21% | 18–24% |
| Safety and Infection Prevention and Control | 10–16% | 10–16% |
| Health Promotion and Maintenance | 6–12% | 6–12% |
| Psychosocial Integrity | 6–12% | 9–15% |
| Basic Care and Comfort | 6–12% | 7–13% |
| Pharmacological and Parenteral Therapies (RN) / Pharmacological Therapies (PN) | 13–19% | 10–16% |
| Reduction of Risk Potential | 9–15% | 9–15% |
| Physiological Adaptation | 11–17% | 7–13% |
Individual exams may vary by up to ±3 percent per category.
Reading the differences
Four gaps are worth understanding, because each one tells you something about what the exam expects.
Pharmacology. The RN category is “Pharmacological and Parenteral Therapies” at 13–19 percent. The PN category is “Pharmacological Therapies” at 10–16 percent. The RN version explicitly includes parenteral therapy and carries a materially higher weight. IV therapy, central lines, blood administration, and titration sit here, and RN candidates should expect more of it.
Physiological Adaptation. RN 11–17 percent versus PN 7–13 percent. This category covers unstable patients — hemodynamics, medical emergencies, pathophysiology of acute deterioration. The RN exam weights it substantially higher, consistent with RN responsibility for assessment and clinical decision-making in unstable situations.
Care coordination. “Management of Care” for the RN at 15–21 percent, “Coordinated Care” for the PN at 18–24 percent. The PN weight is higher, which surprises people, but the names signal different content. The RN category reflects accountability for assignment, delegation, and supervision. The PN category reflects contributing to coordinated care within a directed role.
Psychosocial Integrity. PN 9–15 percent versus RN 6–12 percent. The PN exam weights this higher.
Scope of practice, as the test plans describe it
The PN test plan describes the LPN/LVN as functioning “within the limits of educational preparation and experience,” collaborating with the interdisciplinary team, and practicing within “the legal scope of practice.”
The RN test plan describes an entry-level registered nurse accountable for care that promotes maintenance or restoration of health.
Translated into how questions behave: RN items more often ask what you will do as the person responsible for the assessment and the decision. PN items more often ask what falls within your scope, when to escalate, and how to contribute to a plan someone else is directing.
This is why “which task can the nurse delegate to the LPN” is a characteristic RN question. Delegation authority is an RN responsibility.
Which is harder
The wrong question, but people ask it, so here is a real answer.
Pass rates, 2025:
| NCLEX-RN | NCLEX-PN | |
|---|---|---|
| First-time, US-educated | 86.7% | 81.9% |
| Repeat, US-educated | 52.7% | 46.8% |
| First-time, internationally educated | 47.3% | 41.2% |
| All candidates | 69.1% | 65.2% |
RN pass rates are higher across every category. That does not mean the RN exam is easier — it means RN candidates completed a longer program and are being measured against a standard calibrated to their preparation.
Each exam is difficult for its own population. The comparison that matters is not RN versus PN but you versus the standard for the exam you are taking.
One trend worth flagging
The RN first-time pass rate for US-educated candidates fell from 91.2 percent in 2024 to 86.7 percent in 2025 — a drop of roughly 4.5 points in a single year, with the passing standard unchanged at 0.00 logits throughout.
Over the same period, the share of first-time RN candidates going to maximum length rose from 16.7 to 20.5 percent. More candidates testing near the line, fewer clearing it comfortably.
The standard did not move. Something on the candidate side did.
If you are choosing between paths
The exams should not drive the decision. Program length, scope of practice, career trajectory, and cost should.
But if you are an LPN considering an LPN-to-RN bridge, understand what changes on the exam: significantly more pharmacology including parenteral therapy, significantly more unstable-patient physiology, and a shift from “what is within my scope” to “what do I assess, decide, and delegate.”
Your clinical experience is genuinely valuable there. It is not sufficient on its own — the RN exam tests a decision-making role your PN preparation was not built around.

Frequently asked questions
Common follow-up questions on Exam Basics & Logistics.
What is identical between the NCLEX-RN and NCLEX-PN?
Both are 85 to 150 items of variable-length computerized adaptive testing over five hours including all breaks, both have 15 unscored pretest items on every exam, and both include 18 clinical judgment case study items (three case studies of six items each) on a minimum-length exam. They also use the same test center procedures, ID rules, and break structure, and their test plans both run April 1, 2026 through March 31, 2029.
How do the passing standards differ?
The NCLEX-RN passing standard is 0.00 logits and the NCLEX-PN is -0.18 logits, both effective through March 31, 2029. The lower PN standard is not a statement that PN candidates are held to a weaker version of the same job; it reflects a different scope of practice with different entry-level expectations, and each exam is calibrated against its own practice analysis.
How does the content differ between the two exams?
The RN category Pharmacological and Parenteral Therapies is 13 to 19 percent and explicitly includes parenteral therapy, versus the PN's Pharmacological Therapies at 10 to 16 percent, so RN candidates face more IV therapy, central lines, blood administration, and titration. Physiological Adaptation is also weighted higher for the RN (11 to 17 percent versus 7 to 13 percent), while the PN weights Coordinated Care and Psychosocial Integrity higher.
Which exam has higher pass rates?
RN pass rates were higher across every category in 2025, for example 86.7 percent versus 81.9 percent for first-time US-educated candidates. That does not mean the RN exam is easier; it means RN candidates completed a longer program and are measured against a standard calibrated to their preparation. Each exam is difficult for its own population.
What changes on the exam for an LPN bridging to RN?
Significantly more pharmacology including parenteral therapy, significantly more unstable-patient physiology, and a shift from what is within my scope to what do I assess, decide, and delegate. Clinical experience is genuinely valuable but not sufficient on its own, because the RN exam tests a decision-making role that PN preparation was not built around.
