Exam Format at a Glance
Certification in Pediatric Infectious Diseases is administered by the American Board of Pediatrics (ABP) as an initial subspecialty certifying examination - not the in-training SITE exam and not the MOCA-Peds longitudinal assessment used for renewal. ABP describes its subspecialty certifying exams as half-day, multiple-choice examinations, delivered on computer through Prometric testing centers after ABP authorizes a candidate's eligibility. The Pediatric Infectious Diseases Society (PIDS) notes the exam follows a biennial schedule, so candidates who miss a cycle should plan well ahead rather than assume annual availability.
If you're still mapping out the exact sequence of eligibility, application, and test-day steps, the PID Requirements guide and the PID Exam Dates guide walk through the timeline in more detail than a cheat sheet can.
Scoring Snapshot
ABP reports results on a scaled 1-300 range, with 180 marking the passing threshold. This is a scaled standard, not a raw percentage of questions answered correctly, which means the number of correct answers required to reach 180 is not published as a fixed percentage. Don't try to reverse-engineer a "percent correct" target from the 180 figure - focus on breadth across the full outline instead. For a deeper breakdown of how scaled scoring works and what it means for how you allocate study time, see the PID Passing Score guide.
Key Takeaway
180 out of 300 is the passing score - treat it as a scaled benchmark, not a percentage, and don't waste time calculating a "safe" raw-score cutoff.
Registration & Fee Mechanics
Budgeting matters because Certification in Pediatric Infectious Diseases is not a low-cost, walk-in exam. The published 2026 summer/fall ABP subspecialty fee schedule lists new-applicant regular registration at $2,992, which includes a $750 processing fee, and regular re-registration at $2,242, in USD. Treat these figures as a budgeting reference tied to that specific published schedule rather than a guaranteed quote for every future Pediatric Infectious Diseases administration - fees are published per cycle, so confirm the current schedule before you register.
- New applicant, regular registration: $2,992 (includes $750 processing fee)
- Regular re-registration: $2,242

The 2026 Blueprint: 22 Domains, 196 Subdomains
The ABP-authored practice analysis published in October 2025 revised the content outline to 22 domains and 196 subdomains. This replaces older, informal "eight-category" summaries that still circulate in commercial study materials - if a resource you're using references eight broad categories instead of the ABP outline structure, it's out of date. Always align your review to the current ABP subspecialty content outline rather than a legacy framework.
Two directional shifts matter most for 2026 preparation:
- Increased weighting: cardiovascular infections, bone and joint infections, and urologic infections
- Decreased weighting: antimicrobial principles
This doesn't mean antimicrobial principles can be skipped - it remains a foundational topic - but it does mean disproportionate hours spent purely on drug mechanisms and pharmacokinetics at the expense of organ-system infection presentations is now a less efficient use of study time than it may have been under prior outlines. For the complete list of all 22 domains with subdomain detail, see the PID Exam Domains Guide.
High-Yield Topic Priorities
Beyond the official outline, several recurring clinical themes show up across pediatric infectious disease practice and are worth deliberate review time. These are editorial study priorities, not a substitute for the official ABP domain list - use them to organize your question practice within the outline, not instead of it.
Organ-System Infections
Given the increased weighting on cardiovascular, bone and joint, and urologic infections, candidates should be comfortable moving fluently between presentation, imaging correlation, and empiric-to-targeted therapy decisions for each system.
- Endocarditis and myocarditis presentations in children
- Osteomyelitis and septic arthritis diagnostic pathways
- Pediatric urinary tract infection management and complications
Neonatal and Congenital Infections
Timing of exposure, maternal history, and age-specific presentation differences are frequently tested through case vignettes rather than isolated fact recall.
- Congenital infection syndromes and screening
- Early- vs. late-onset neonatal sepsis distinctions
- Perinatally acquired viral and bacterial infections
Immunocompromised Hosts and Stewardship
Cases involving oncology, transplant, or primary immunodeficiency patients require layered reasoning across infection risk, prophylaxis, and antimicrobial stewardship principles.
- Risk-stratified empiric therapy in febrile neutropenia
- Stewardship principles applied at the bedside, not just in policy
- Vaccination timing and safety in immunocompromised children
Practicing case-style questions across these themes - rather than isolated fact review - mirrors how the exam presents pediatric clinical vignettes. If you want a broader sense of how demanding this mix of case reasoning and breadth actually is, the How Hard Is the PID Exam guide and the PID Pass Rate guide put the difficulty in context.
Eligibility Checklist
Before you can register, ABP requires several pieces of documentation to be in place. Missing any one of these is a common reason candidates delay a cycle:
- Satisfactory fellowship-training verification from your program director
- Active, unrestricted medical licensure
- Professional standing documentation
- An accepted scholarly work product, verified by both the program director and the Scholarship Oversight Committee
The scholarly work product requirement is the piece most often underestimated in timeline planning - it involves institutional sign-off, not just a completed project. Build in buffer time well before your intended registration window. A full walkthrough of each requirement lives in the PID Requirements guide.
Continuing Certification Cycle
Certification in Pediatric Infectious Diseases does not end at the initial exam. Continuing certification is built on four pillars: professional standing, lifelong learning/self-assessment, assessment of knowledge, and improvement in practice. According to the PIDS maintenance guide, the cycle runs in five-year increments requiring 100 total points, broken down as:
- At least 40 Part 2 points
- At least 40 Part 4 points
- 20 additional points in either Part 2 or Part 4
MOCA-Peds is the longitudinal knowledge-assessment pathway used within this continuing-certification structure. It is a separate track from initial-certification exam preparation, so keep your renewal-focused study materials distinct from the case-based review you're doing for the initial exam - mixing the two often wastes prep time on the wrong assessment format.
Key Takeaway
100 MOC points over five years, split at least 40/40 across Part 2 and Part 4, with 20 flexible points - plan renewal activities early rather than compressing them near cycle-end.
Initial Certification vs. Continuing Certification
| Aspect | Initial Certifying Exam | Continuing Certification (MOC) |
|---|---|---|
| Format | Half-day, computer-based, multiple-choice, Prometric delivery | Ongoing activities plus MOCA-Peds longitudinal assessment |
| Schedule | Biennial administration | Five-year point-accrual cycle |
| Scoring/Requirement | 1-300 scale; 180 to pass | 100 points: 40+ Part 2, 40+ Part 4, 20 flexible |
| Fee Reference | $2,992 new applicant (incl. $750 processing fee) | $2,242 re-registration reference figure |
A Domain-Aligned Review Schedule
Generic study techniques only help if they're mapped to the actual outline weighting. Given the shift toward cardiovascular, bone and joint, and urologic infections - and the reduced emphasis on antimicrobial principles - a late-stage review block should visibly reflect that balance rather than treat all 22 domains as equal.
Organ-System Infections
- Drill cardiovascular, bone/joint, and urologic infection vignettes given their increased outline weighting
- Pair each topic with imaging and lab-interpretation questions, not just pathogen recall
Neonatal, Congenital, and Immunocompromised Cases
- Practice case-style questions that combine host risk factors with therapy decisions
- Review vaccination timing rules specific to immunocompromised patients
Antimicrobial Principles and Stewardship (Lighter Pass)
- Confirm core pharmacology and stewardship logic without over-investing hours here
- Use spaced review of missed questions from earlier weeks instead of new antimicrobial deep-dives
For a longer-horizon plan that spans full fellowship-year preparation, the PID Study Guide lays out a complete first-attempt strategy, and running timed practice sets on the main practice test platform is one of the most direct ways to see which of these domain clusters still need work before test day.
Once you've built a study rhythm, cross-check your confidence level against realistic expectations - the Is PID Certification Worth It guide and PID Salary Guide are useful context for why fellows commit this level of preparation time in the first place, and practicing regularly on the practice test site keeps your recall sharp closer to your scheduled Prometric date.
FAQ
