The 2025 first-time pass rate was 78.84%. The initial exam fee is $407, including a $134 nonrefundable registration fee. Re-examination costs $288, and a testing-window extension costs $155.
CPNP-AC Exam Structure, Scoring & Blueprint Architecture
Quick Answer: The Pediatric Nursing Certification Board (PNCB) gives candidates 3 hours for 175 multiple-choice questions at a PSI test center. Of those, 150 are scored. The passing scaled score is 400 on a 200–800 scale. Management and Assessment together account for 107 of the 150 scored questions. The initial exam fee is $407, including a $134 nonrefundable registration fee.
Role and Purpose of the CPNP-AC Credential
The Certified Pediatric Nurse Practitioner - Acute Care (CPNP-AC) credential certifies advanced practice registered nurses (APRNs) who provide care to physiologically unstable, critically ill, technologically dependent, or chronically complex pediatric patients from birth through young adulthood. Administered by the Pediatric Nursing Certification Board (PNCB), this national board examination validates advanced clinical assessment, complex pathophysiology interpretation, diagnostic synthesis, pharmacological management, and invasive procedural decision-making.
The credential can support applications for state advanced practice licensure and employer credentialing. Verify the state’s licensing requirements and the employer’s privileges before accepting responsibility for a procedure or service. Common practice settings include pediatric intensive care units (PICUs), cardiac intensive care units, emergency departments, inpatient services and acute subspecialty teams.
Examination Architecture and Testing Logistics
The CPNP-AC examination is administered in person only at PSI testing centers, with locations in the United States and Canada. Candidates must complete 175 multiple-choice questions within 3 hours (180 minutes).
| Operational Parameter | Specification |
|---|---|
| Total Delivered Items | 175 multiple-choice questions |
| Scored Items | 150 items |
| Unscored Pretest Items | 25 pilot items (embedded seamlessly across the test) |
| Total Testing Time | 3 hours (180 minutes) |
| Average Pacing | Approximately 61.7 seconds per item |
| Delivery Format | In-person only Computer-Based Testing (CBT) at PSI Services testing centers (no live remote proctoring) |
| Initial Examination Fee | $407 (includes $134 non-refundable registration/processing fee) |
| Testing-Window Extension Fee | $155 (one-time 90-day testing-window extension) |
| Re-Examination Fee | $288 |
| Retake Policy | Wait at least 30 days from the first exam date before reapplying for attempt two. Later attempts have a minimum 90-day wait, subject to a limit of three attempts in any rolling 12-month period. |
Scheduling and Retesting
PNCB assigns a 90-day window on approval. Use the scheduling link in your PNCB portal to choose a PSI appointment within that window. For an extension, apply at least five business days before the current window expires. A single replacement 90-day window begins when PNCB processes the extension.
Under the January 2026 PNCB retest policy, PNCB requires no remedial education documentation for attempt two. For attempt three, submit a certificate from an acute care PNP review course or document 15 accredited contact hours in each weak content area on the score report. For attempt four, complete the other remediation option. Complete these activities after the most recent attempt and within the 12 months before reapplying. After a fourth unsuccessful attempt, consult PNCB for next steps. The rolling attempt limit can make the wait longer than the published minimum.
Scored vs. Unscored Pretest Items
Of the 175 questions on each form, exactly 25 are unscored pretest items. PNCB reviews pretest item performance before deciding whether to use the items for scoring on future exam forms. Because pretest items are indistinguishable from scored questions, candidates must treat every question with equal diligence.
Psychometric Standards and Criterion-Referenced Scoring
The CPNP-AC examination uses criterion-referenced standard setting. Candidates are evaluated against a predetermined standard of clinical competence set by PNCB using input from a representative panel of subject-matter experts who hold the credential.
Scaled Scoring Framework
Raw scores (the total number of correctly answered scored items out of 150) are converted to a standardized scaled score ranging from 200 to 800 using statistical equating. Statistical equating accounts for slight differences in difficulty between different test forms administered across testing windows.
- Minimum Passing Standard: A scaled score of 400 is required to pass.
- Raw Score Equivalent: The raw number of correct answers needed may vary by form. PNCB publishes the scaled cut score of 400.
- Score Reporting: Most candidates see preliminary pass/fail status at the testing center. PNCB usually emails official results within 2–3 weeks. An unsuccessful candidate receives a scaled score and feedback on the major content areas to guide further study.
Historical Pass Rates and National Trends
PNCB reported first-time pass rates of 66.67% in 2023, 69.57% in 2024, and 78.84% in 2025. Its 2025 report lists 569 total candidates who tested that calendar year and 5,342 active CPNP-AC certificants at year-end. The first-time pass rate describes a subset of the candidates who tested. Use your performance on practice scenarios to identify where you need more study.

PNCB Examination Blueprint Domains
PNCB’s Detailed Content Outline, dated June 2024 and effective December 2024, describes four scored domains. Use its task list to practice decisions, its clinical problem list to vary the cases, and its procedures list to review indications, benefits, risks and complications.
| Blueprint Domain | Weight (%) | Scored Questions | Primary Clinical Focus |
|---|---|---|---|
| Domain I: Assessment | 34% | 51 items | Physical exam, invasive hemodynamic data, diagnostic imaging, lab panel synthesis, patient history |
| Domain II: Diagnosis | 24% | 36 items | Differential diagnosis, clinical trajectory recognition, pathophysiology, acute vs. chronic decompensation |
| Domain III: Management | 37% | 56 items | Pharmacotherapy, invasive mechanical ventilation, fluid resuscitation, procedural execution, complications |
| Domain IV: Professional Practice Role | 5% | 7 items | Ethics, pediatric assent/consent, APRN scope, quality improvement, interprofessional handoffs |
Domain I: Assessment (34%)
Domain I evaluates the clinician's ability to systematically gather and synthesize subjective and objective data from acutely ill pediatric patients. Key competencies include:
- Rapid identification of impending cardiopulmonary collapse using observational assessment tools.
- Interpretation of invasive hemodynamic monitoring waveforms (central venous pressure, arterial line pulse contour analysis, pulmonary artery catheters).
- Evaluation of complex laboratory parameters (blood gas acid-base analysis, coagulation profiles, thromboelastography [TEG], continuous lactate clearance).
- Recognition of critical diagnostic imaging findings (tension pneumothorax, pulmonary consolidations, acute intracranial hemorrhage, bowel perforation, hardware displacement).
Domain II: Diagnosis (24%)
Domain II focuses on clinical diagnostic synthesis and underlying pathophysiologic mechanisms:
- Generating prioritized differential diagnoses based on age-specific disease incidence.
- Distinguishing acute decompensation from baseline chronic pediatric illness (e.g., status asthmaticus vs. bronchopulmonary dysplasia flare; cyanotic spell vs. worsening shunt failure).
- Identifying atypical presentations of life-threatening conditions in neonates and immunocompromised pediatric hosts.
Domain III: Management (37%)
As the largest domain on the examination, Management evaluates therapeutic intervention and crisis stabilization:
- Pharmacologic management: vasoactive inotropes and vasopressors, broad-spectrum antimicrobial stewardship, antiarrhythmic agents, anticonvulsants, analgesia, and procedural sedation.
- Invasive mechanical ventilation strategies: lung-protective ventilation, high-frequency oscillatory ventilation (HFOV), and airway pressure release ventilation (APRV).
- Resuscitation protocols: targeted fluid resuscitation, massive transfusion protocols (MTP), and continuous renal replacement therapy (CRRT).
- Managing acute procedural complications: accidental extubation, pneumothorax decompression, and loss of critical central vascular access.
Domain IV: Professional Practice Role (5%)
Domain IV tests the non-clinical foundations of advanced practice:
- Healthcare ethics: pediatric assent, parental surrogate decision-making, ethical dilemmas in withholding or withdrawing life-sustaining therapy.
- Legal parameters: APRN Consensus Model, collaborative practice agreements, institutional privileging.
- Systems-based practice: evidence-based clinical practice guidelines, patient safety root-cause analysis, and structured handoff models (e.g., IPASS).
Candidate Eligibility and Educational Verification
To be approved by the PNCB to sit for the CPNP-AC examination, candidates must meet rigorous academic, regulatory, and clinical prerequisites:
- Current Registered Nurse Licensure: Active, unencumbered RN license in the United States, its territories, or Canada.
- Qualifying Education: Complete a qualifying master’s or doctoral nursing program with an acute care pediatric NP concentration or formal dual primary/acute care preparation. The nursing program must be accredited by ACEN, CCNE, or NLN CNEA. A post-master’s pediatric acute care NP certificate from an accredited college or university is another route.
- Clinical Hours: Complete at least 500 supervised direct patient-care hours in acute care pediatrics within the educational program. PNCB strongly recommends 600 hours. Eligible direct care can include telehealth and global health experiences. Simulation may be used for hours above the 500 direct-care minimum.
- Coursework and Application: Complete three separate comprehensive graduate courses in advanced physiology/pathophysiology, advanced health assessment and advanced pharmacology. Arrange for your school to send the final official transcript to PNCB and complete the required Ethics in Testing module before applying.
PNCB has a limited final-transcript exception for candidates who meet its criteria. Candidates who pass using the exception must still provide the final transcript before certification. See PNCB transcript requirements. The announced requirement to have graduated within five years of applying begins January 1, 2030.
See PNCB eligibility and the steps to certification for application details.
Clinical Reasoning and Strategic Preparation for APRN Candidates
Passing the CPNP-AC examination requires transitioning from basic registered nurse recall to high-level APRN clinical synthesis. Candidates should adopt specific cognitive strategies during preparation:
1. Pacing and Time Management
With 175 questions in 180 minutes, the average is about 61.7 seconds per item. If you reserve the last 10 minutes for review, you have about 58 seconds per item on the first pass. In a clinical vignette, identify the patient’s age, vital signs and change from baseline.
2. The "Airway, Breathing, Circulation" Priority Hierarchy
If a vignette describes a threat to airway, ventilation or circulation, decide what support is needed immediately. In suspected septic shock, delegate blood cultures if they can be obtained without substantially delaying antimicrobials and begin stabilization in parallel. See the 2026 pediatric sepsis guideline.
3. Acute vs. Chronic Distinctions
Exam items frequently test whether the candidate can discern an acute life-threat superimposed on chronic underlying disease. In a child who uses home oxygen, compare current oxygen needs, work of breathing, and alertness with the caregiver’s description of baseline. A new increase in oxygen need plus decreased alertness should prompt urgent reassessment and escalation.
An APRN candidate is reviewing the psychometric scoring methodology of the PNCB CPNP-AC board examination. Which statement accurately describes how the passing score is established and reported?
PNCB uses criterion-referenced Angoff standard setting and equates forms to a common passing scaled score of 400 on a 200–800 scale.
Candidates must score in the top 30th percentile relative to the national cohort sitting during the same testing window.
The passing cut score requires achieving exactly 75% raw correct answers on all 175 delivered examination items.
The raw score is graded on a linear curve where any candidate answering at least 120 of the 150 scored items passes automatically.
When organizing a dedicated clinical study plan for the CPNP-AC examination, which domain distribution reflects the official PNCB content outline and warrants the greatest allocation of study time?
Assessment (45%) and Diagnosis (35%), with Management and Professional Practice comprising the remaining 20%.
Management (56 scored items) and Assessment (51 scored items), the two largest domains.
Diagnosis (40%) and Management (30%), followed by Assessment (20%) and Professional Role (10%).
Assessment, Diagnosis, and Management are weighted equally at 30% each, with Professional Practice allocated 10%.
Four applicants have completed the PNCB ethics module and can send a final transcript. Which applicant meets the RN license, program, and clinical practice requirements to apply for CPNP-AC?
Graduation from an accredited Family Nurse Practitioner (FNP) program with 300 hours of emergency room clinical immersion and 2 years of pediatric ICU nursing experience.
An active, unrestricted RN license, completion of a primary care PNP program, and 250 hours of inpatient acute care elective rotations.
An applicant with an active, unencumbered RN license, a qualifying accredited acute care PNP program including the three required graduate courses, and 500 supervised direct patient-care hours in acute care pediatrics.
A Master of Science in Nursing in pediatric primary care, board certification through PNCB as a CPNP-PC, and 1,000 hours of hospitalist employment without formal acute care graduate coursework.
