- PEM is the ABP-administered subspecialty certification in Pediatric Emergency Medicine, distinct from ABEM's separate credentialing route.
- The exam runs in two 2-hour-15-minute sections (4 hours 30 minutes total) at Prometric centers, next offered April 13, 2027.
- Passing requires a scaled score of 180 on ABP's 1-to-300 scale - not a percentage of items correct.
- The standard pathway needs general pediatrics certification plus three years of accredited PEM fellowship training.
What Is PEM, Exactly?
PEM stands for Certification in Pediatric Emergency Medicine, a subspecialty credential issued by the American Board of Pediatrics (ABP) to pediatricians who complete additional fellowship training focused on the emergency care of infants, children, and adolescents. It is not a nursing certificate, not PALS, and not a generic "provider" designation - it is a physician subspecialty board certification layered on top of general pediatrics certification.
If you've landed here after searching a broader question, our companion pieces on PEM Meaning and What Does PEM Stand For? unpack the terminology in more depth, while PEM Certification covers the credential itself at a high level. This article focuses specifically on what candidates need to know about the exam, its structure, and how to prepare using resources on our practice test platform.
Who Administers the PEM Certification?
The American Board of Pediatrics develops and administers the PEM examination content that both ABP-certified and ABEM-certified candidates ultimately sit for, but the two boards separately manage eligibility, applications, fees, and result reporting for their respective applicant populations. For candidates entering through general pediatrics, ABP is the certifying body of record.
This matters practically: if you're comparing costs, dates, or requirements online, make sure you're reading ABP-specific pages rather than ABEM material, since the two pathways diverge on registration mechanics even though they share the same exam content. Our PEM Requirements 2026 guide walks through the ABP pathway's prerequisites in detail.
The 13 PEM Exam Domains
The PEM examination blueprint currently in effect (through March 31, 2027) organizes content into 13 domains, each weighted by percentage of exam questions. Three domains - Emergency Conditions, Trauma, and Resuscitation - together account for the majority of scored items, making them the highest-leverage areas for study time.
Domain 1: Emergency Conditions (32.5%)
The single largest domain by far, covering acute presentations across pediatric organ systems that bring children to the emergency department.
- Recognizing time-sensitive deterioration patterns
- Differentiating common mimics of serious illness
Domain 3: Trauma (17.5%)
The second-largest domain, reflecting the centrality of injury management in pediatric emergency practice.
- Primary and secondary trauma survey in children
- Age-specific injury patterns and imaging decisions
Domain 2: Resuscitation (12.5%)
Covers stabilization of critically ill or injured children, including airway, circulation, and shock management specific to pediatric physiology.
The remaining ten domains carry smaller individual weights but are still tested every sitting: Toxicology (5.0%), Behavioral Health Conditions and Psychosocial Issues (5.0%), Child Abuse and Maltreatment (4.5%), Environmental Emergencies (4.0%), Core Knowledge in Scholarly Activities (4.0%), Procedures (6.0%), Special Populations (3.0%), Disaster Preparedness (2.0%), Emergency Medical Services and Transport (2.0%), and Emergency Department Administration and Operations (2.0%).

Exam Format, Delivery, and Timing
PEM is a computer-based multiple-choice examination delivered at Prometric testing centers. The ABP subspecialty schedule structures the exam as two sections of 2 hours and 15 minutes each, for a total of 4 hours and 30 minutes of active testing time. Candidates receive an optional break of up to 30 minutes between sections, plus additional administrative time for check-in and instructions.
The exam is offered in odd-numbered years, with the next published sitting on April 13, 2027. Because certification sittings are infrequent relative to annual-exam credentials, missing a sitting has real consequences for career timing - plan registration and study around the published date well in advance. Full scheduling details, including how registration deadlines interact with the testing window, are covered in PEM Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
| Feature | Detail |
|---|---|
| Testing sections | Two sections, 2 hours 15 minutes each |
| Total active testing time | 4 hours 30 minutes |
| Break | Optional, up to 30 minutes |
| Delivery format | Computer-based, multiple-choice, Prometric centers |
| Testing frequency | Odd-numbered years |
| Next sitting | April 13, 2027 |
Registration Costs and Fees
The ABP regular registration fee for the PEM examination is USD 2,992, which includes a USD 750 processing component. This fee applies to the ABP physician pathway described in this article; ABEM-route application and examination fees are handled entirely separately and should not be substituted when budgeting for the ABP process.
For a full breakdown of what this fee covers, how it compares to related costs like fellowship expenses or study materials, and how to budget across the certification timeline, read PEM Certification Cost 2026: Complete Pricing Breakdown.
Who Is Eligible to Sit for PEM?
The standard pediatrics pathway to PEM certification requires several sequential steps rather than a single application:
- General pediatrics certification through ABP
- Three years of accredited PEM fellowship training
- Satisfactory competence evaluations from fellowship supervisors
- Satisfactory scholarly-activity evaluations
- Compliance with ABP licensure and professional-standing requirements
ABEM-route eligibility follows a different application process managed entirely through ABEM and is outside the scope of the standard pediatrics pathway. For a step-by-step eligibility checklist and common disqualifying gaps, see PEM Requirements 2026: Eligibility, Prerequisites & How to Qualify.
How PEM Is Scored
PEM uses a scaled scoring system rather than a raw percentage-correct cutoff. The passing standard is a scaled score of 180 on ABP's 1-to-300 scale. This means candidates should not fixate on "getting 60% right" as a benchmark - the scaling accounts for item difficulty across the exam, so score reports and preparation strategy should be interpreted in scaled-score terms.
Key Takeaway
Because passing is defined by a scaled score of 180, not a fixed percentage, focus your review on domain mastery rather than trying to reverse-engineer a "percent correct" target. See PEM Passing Score 2026: Exactly What You Need to Pass for a full explanation of how the scale works.
Maintaining PEM Certification
Initial PEM certification and ongoing maintenance are distinct processes. Continuing certification under ABP includes four components: professional standing, self-assessment, knowledge assessment, and quality improvement. The ABMS directory lists 50 ABP MOC Part 2 self-assessment points required per five-year cycle as part of this ongoing requirement.
It's worth noting explicitly that initial certification and MOCA-Peds are different assessments serving different purposes - one establishes the subspecialty credential, the other supports ongoing maintenance. Confusing the two when planning your timeline can lead to missed deadlines later in your career.
Who Pursues PEM Certification, and Why
PEM-certified physicians typically work in pediatric emergency departments at children's hospitals, academic medical centers with pediatric EDs, and combined adult/pediatric emergency departments that need dedicated pediatric emergency expertise. The credential signals that a physician has completed dedicated fellowship training beyond general pediatrics and has demonstrated competency across the full breadth of pediatric emergency presentations - not just the acute conditions covered in Domain 1, but trauma, toxicology, behavioral health crises, and abuse recognition as well.
Employers hiring for pediatric emergency medicine roles frequently list board certification (or board eligibility pending exam results) as a baseline requirement, since it is the recognized marker of subspecialty training in this field. If you're evaluating whether the investment of fellowship time and exam fees pays off across a career, Is the PEM Certification Worth It?

Mapping a Study Plan to the Blueprint
Because Emergency Conditions, Trauma, and Resuscitation together represent well over half of the exam's weight, an efficient study sequence starts there before moving to the smaller domains. A reasonable approach:
Emergency Conditions and Resuscitation
- Build depth here first since it carries the most weight and underlies later topics
- Use timed question blocks to simulate the two 2-hour-15-minute sections
Trauma and Procedures
- Layer in trauma survey sequencing and procedural indications
- Cross-reference with Emergency Conditions material for overlap
Lower-weight domains
- Toxicology, Behavioral Health, Child Abuse and Maltreatment, Environmental Emergencies
- Disaster Preparedness, EMS and Transport, ED Administration, Scholarly Activities
Full-length practice and review
- Run full timed sessions mirroring the actual 4-hour-30-minute format
- Revisit weak domains identified through practice performance
Generic techniques like spaced repetition or timed blocks only help if they're applied against the actual PEM weighting rather than studied evenly across all 13 domains. For a more detailed week-by-week framework and first-attempt strategy, see PEM Study Guide 2026: How to Pass on Your First Attempt, and for realistic difficulty expectations going in, review How Hard Is the PEM Exam? Complete Difficulty Guide 2026. You can practice against domain-weighted question sets on our practice test platform to get a feel for the exam's pacing before test day.
Frequently Asked Questions
No. ABP develops and administers the shared PEM examination content, but ABP and ABEM separately handle eligibility, applications, fees, and results for their respective applicant pools. This article covers the ABP physician pathway.
The PEM certification examination is offered in odd-numbered years. The next published sitting is April 13, 2027.
You need a scaled score of 180 on ABP's 1-to-300 scale - not a fixed percentage of questions answered correctly.
The exam consists of two sections of 2 hours and 15 minutes each, totaling 4 hours and 30 minutes of active testing, plus an optional break of up to 30 minutes.
Not necessarily. The domain percentages in this article reflect the outline effective through March 31, 2027. A replacement outline takes effect April 1, 2027, and applies to the April 13, 2027 sitting, so those percentages should not be treated as that sitting's confirmed blueprint.
