Who Issues the CPNP-AC and Who Tests It
The Certified Pediatric Nurse Practitioner - Acute Care credential is issued by the Pediatric Nursing Certification Board (PNCB), with exams delivered through testing provider PSI. If you are new to the credential itself, start with What Is CPNP-AC? or What Does CPNP-AC Stand For?, then come back to this page as your one-sheet review.
Everything below is built from PNCB's own documents: the Detailed Content Outline (published June 2024, effective December 2024, based on the 2023-2024 Job Task Analysis), the Exam Candidate Handbook, and PNCB's eligibility, scoring, and fee pages. Because policies and fees change, always confirm against PNCB before you pay or schedule.
Exam Format at a Glance
| Feature | CPNP-AC Detail |
|---|---|
| Total questions | 175 single-best-answer multiple-choice |
| Scored items | 150 |
| Unscored pretest items | 25 (indistinguishable from scored items) |
| Time limit | 3 hours |
| Test design | Fixed length, nonadaptive |
| Review | You can revisit answers before final submission |
| Passing standard | Scaled score of 400 (scale 200-800) |
| Reference materials | Closed-book; personal study materials prohibited |
Two practical consequences follow. First, because the exam is nonadaptive, the difficulty of the next question does not depend on whether you got the last one right, so you cannot read your performance from the questions themselves. Second, because you can revisit answers, a sound approach is to answer everything on a first pass, flag the uncertain items, and spend remaining time on the flags. Since you cannot tell which 25 items are unscored, treat every question as if it counts.

The Four Weighted Domains
The official blueprint has exactly four weighted domains. These are exam objectives, not preparation-course modules, so do not assume any prep course maps one-to-one onto them. PNCB publishes rounded percentages; keep those published figures rather than recalculating from item counts.
| Domain | Published Weight | Scored Items |
|---|---|---|
| Domain 1: Assessment | 34% | 51 |
| Domain 2: Diagnosis | 24% | 36 |
| Domain 3: Management | 37% | 56 |
| Domain 4: Professional Practice Role | 5% | 7 |
Domain 3: Management (37%, 56 items)
The largest slice of the exam. Expect questions that ask what you do next for an acutely ill or unstable child, not just what is wrong.
- Selecting first-line interventions and escalation steps
- Medication choices, dosing logic, and monitoring, using generic names
- Stabilization, disposition, and follow-up planning
Domain 1: Assessment (34%, 51 items)
Nearly as large as Management. This is where focused history, physical findings, and interpretation of data are tested.
- Recognizing the sick child versus the stable child
- Interpreting vital signs, exam findings, and diagnostic data
- Knowing which data to gather first when time matters
Domain 2: Diagnosis (24%, 36 items)
Moving from data to a differential and a working diagnosis.
- Prioritizing the most likely and most dangerous diagnoses
- Matching presentations to pathophysiology
Domain 4: Professional Practice Role (5%, 7 items)
Small but not zero. Seven items can matter when your score sits near the line, so do not ignore it entirely.

Scoring: What 400 Actually Means
The passing score is a scaled 400 on a 200-800 scale. It is not a fixed raw percentage, so you cannot convert it into a simple "answer X of 150 correctly" target. Scaling accounts for differences in difficulty between exam forms. The practical takeaway: aim for solid command of every high-weight domain rather than chasing a magic percent-correct number. Details are in CPNP-AC Passing Score: Exactly What You Need to Pass.
The 2025 Results
PNCB's 2025 exam statistics (updated April 14, 2026) report a calendar-year 2025 first-time pass rate of 78.84%. They also report that 569 candidates tested in total and that 5,342 people held active CPNP-AC certification on December 31, 2025.
Eligibility Checklist
Candidates must satisfy every item below before applying. The full walkthrough lives in CPNP-AC Requirements: Eligibility, Prerequisites & How to Qualify.
- License: current, active, unencumbered RN license from a US state, US territory, or Canada.
- Education: an accredited nursing master's or doctorate with pediatric acute-care (or eligible dual-focus) NP preparation, or an eligible post-master's acute-care PNP certificate.
- Clinical hours: at least 500 supervised direct-care acute-care pediatric hours. 600 is recommended, not required. Simulation cannot substitute for the direct-care minimum.
- Separate graduate courses: advanced physiology/pathophysiology, health assessment, and pharmacology.
- Transcripts: official final transcripts sent by your school.
- Ethics in Testing: complete PNCB's free module before applying.
Fees, Registration, and Testing Windows
| Item | Amount |
|---|---|
| Initial examination fee | USD 407 (includes USD 134 nonrefundable registration) |
| Re-examination | USD 288 |
| Testing-window extension | USD 155 (effective October 1, 2025) |
Use the dated Exam Candidate Handbook and PNCB's current application page for fees; older appointment-page copy should not override them. Your authorization comes with an assigned 90-day testing window, and an extension costs the USD 155 above. Because the registration portion is nonrefundable, do not apply until your transcripts, hours, and coursework are fully in order. A complete cost picture, including prep spending, is in CPNP-AC Certification Cost: Complete Pricing Breakdown, and scheduling mechanics are covered in CPNP-AC Exam Dates: Testing Windows, Deadlines & Scheduling.
Test Center vs. Remote Proctoring: The Conflict
PNCB's own materials do not line up perfectly, and a careful candidate should know why.
- The credential-specific Exam Candidate Handbook limits CPNP-AC to year-round test-center delivery within your assigned 90-day window.
- The CPNP-AC administration webpage advertises remote proctoring, and special-timeline banners persist on the site.
The handbook carries an "Effective May 2025" cover and a "Revised 7/2/2026" notation on its final page; both describe the document retrieved, so check for newer versions when you apply.
Test-Day Rules That Affect Your Strategy
- Closed-book: personal study materials are prohibited in the testing area.
- Breaks do not pause the clock: every minute away from the screen comes out of your three hours.
- Generic drug names: PNCB's FAQ expects familiarity with generic medication names, so drill generics rather than brand names.
- Lab values: reference ranges are not typically provided, so know the pediatric norms that drive decisions (for example, what makes a result critical versus merely abnormal).
Key Takeaway
Budget roughly a minute per question on a first pass (175 questions in three hours), flag the hard ones, and keep break time minimal since the timer keeps running.
Clinical Content to Master
PNCB's clinical-problem priorities are led by respiratory and infectious disease, so build your deepest knowledge there, then branch out across the other systems an acute-care pediatric NP manages. The most useful way to study each condition is through all three clinical domains:
- Assess: What findings and data distinguish this condition from its mimics?
- Diagnose: What is the working diagnosis and what are the dangerous alternatives?
- Manage: What is the first intervention, the medication (by generic name), the monitoring, and the disposition?
High-Yield Habits for Acute-Care Pediatrics
The acute-care focus means questions skew toward the unstable or rapidly changing child.
- Practice age-based vital sign and weight-based dosing reasoning, since pediatric norms shift with age
- Rehearse recognition of respiratory compromise and sepsis-type presentations before they become emergencies
- Know escalation triggers: when a child needs higher-level care versus continued observation
- Pair every drug with its generic name, indication, and key adverse effect
For a structured approach to turning these topics into a plan, see the CPNP-AC Study Guide: How to Pass on Your First Attempt, and test yourself under timed conditions with the CPNP-AC practice tests.
A Domain-Weighted Study Sequence
This is the one planning section in this article, and it is tied directly to the blueprint: spend the most time where the items are, and finish by simulating the real format.
Assessment (34%)
- Pediatric history, exam findings, and data interpretation
- Respiratory and infectious disease presentations first
Diagnosis (24%)
- Differentials and pathophysiology linking findings to diagnoses
- Most-likely versus most-dangerous reasoning
Management (37%)
- Interventions, generic-name pharmacology, and disposition
- Give this the longest block because it carries the most items
Professional Practice Role (5%) and Full Review
- Brief professional-role review
- Timed 175-question simulations, then target your weakest domain
Recertification Snapshot
Certification is maintained through annual recertification, with a window of November 1 to January 31. Requirements include current, active, unencumbered licensure and 15 contact hours under the contact-hour-only method, or accepted alternatives. Pediatric Updates and pharmacology requirements are tracked over seven years; that is a tracking period, not a seven-year certification validity period.
