- PID here refers only to the American Board of Pediatrics' Certification in Pediatric Infectious Diseases.
- The exam is a half-day, computer-delivered multiple-choice test administered through Prometric on a biennial schedule.
- Scores are reported on a 1-300 scale, and 180 is the passing score.
- The current content outline has 22 domains and 196 subdomains, with more weight now on cardiovascular, bone/joint, and urologic infections.
What "PID" Means on This Site
Before anything else, a clarification that matters: on PID Exam Prep, "PID" is shorthand for Certification in Pediatric Infectious Diseases, the subspecialty credential issued by the American Board of Pediatrics (ABP). It is not an adult infectious-disease board, not the Subspecialty In-Training Examination (SITE), and not MOCA-Peds - those are distinct assessments with different purposes, and we keep them separate throughout our content. If you landed here searching for a different credential that shares the same three letters, this is not that page.
Everything below describes the pathway pediatric infectious diseases fellows and physicians follow to earn and maintain this specific ABP subspecialty certification. If you want the plain-language explanation of the term itself, see What Is PID?, PID Meaning, or What Does PID Stand For?.
Who Actually Certifies PID
The American Board of Pediatrics is the certifying body. Certification in Pediatric Infectious Diseases is one of ABP's subspecialty credentials, distinct from general pediatric certification and from any adult-medicine infectious disease board. The Pediatric Infectious Diseases Society (PIDS) publishes guidance for fellows on how the exam fits into life after fellowship, including delivery logistics and the biennial testing schedule, but ABP is the entity that authorizes the exam, sets the content outline, and reports scores.
Exam Format and Scoring
ABP describes its subspecialty certifying examinations as half-day, multiple-choice examinations. For Pediatric Infectious Diseases, PIDS notes the exam is delivered by computer through Prometric testing centers after ABP authorizes a candidate, and that the administration follows a biennial schedule rather than being offered every year.
Scoring uses a scaled system, not a raw percentage. ABP reports results on a 1-300 scale, and 180 is the passing score. That means a candidate's number does not represent "percent correct" - it reflects performance against a fixed, psychometrically anchored standard. For a deeper breakdown of what that scale means in practice, see PID Passing Score 2026: Exactly What You Need to Pass. If you're trying to gauge how demanding the test actually is relative to that scoring model, How Hard Is the PID Exam? Complete Difficulty Guide 2026 and PID Pass Rate 2026: What the Data Shows go further into the data ABP has published.
Key Takeaway
Treat 180 on the 1-300 scale as your target, not a percentage. Study toward mastery of the full outline rather than trying to "beat" a curve.
The 22-Domain Content Outline
The exam blueprint candidates should study from is ABP's subspecialty content outline, not an older commercial eight-category list still floating around some study guides. Following an ABP-authored practice analysis published in October 2025, the outline was revised to 22 domains and 196 subdomains. That same analysis reports increased weighting for cardiovascular, bone and joint, and urologic infections, alongside decreased weighting for antimicrobial principles compared with the prior version.
For the full domain-by-domain breakdown, use PID Exam Domains 2026: Complete Guide to All 22 Content Areas as your reference while planning study blocks. In the meantime, these are the categories of clinical knowledge that consistently show up as editorial priorities for exam-takers, based on the structure ABP has emphasized:
Organ-System Infections
Cardiovascular, bone and joint, and urologic infections now carry more weight than in the previous outline version, so candidates should not treat these as secondary topics.
- Endocarditis and myocarditis presentations in pediatric patients
- Osteomyelitis and septic arthritis diagnostic workups
- Complicated and recurrent urinary tract infections
Neonatal and Congenital Infections
A recurring priority area across pediatric ID practice, covering early-onset and late-onset presentations distinct from adult infectious disease patterns.
- Congenital infection screening and management
- Neonatal sepsis evaluation and empiric therapy choices
- Perinatal transmission risk factors
Immunocompromised Hosts
Covers infection risk and management across the range of pediatric immunocompromise, from oncology patients to transplant recipients to primary immunodeficiencies.
- Opportunistic pathogens by host type
- Prophylaxis strategies appropriate to immune status
- Vaccine timing considerations in immunocompromised children
Antimicrobial Principles and Stewardship
This domain's relative weight decreased in the revised outline, but it remains foundational - expect application-style questions rather than pure recall.
- Pediatric dosing and pharmacokinetic differences from adults
- Resistance mechanisms and stewardship program design
- De-escalation and duration-of-therapy decision points
Infection Prevention and Vaccination
A consistent thread across pediatric ID practice and a common source of applied, scenario-based questions.
- Immunization schedules and catch-up strategies
- Outbreak investigation basics in pediatric settings
- Isolation precautions by pathogen and setting
Because these five categories represent editorial study priorities rather than the full official list, pair them with the complete outline in PID Exam Domains 2026: Complete Guide to All 22 Content Areas before finalizing your study calendar.
Eligibility and Application Mechanics
Applying for Certification in Pediatric Infectious Diseases is not simply a matter of registering and showing up. ABP's requirements include several documented components:
- Satisfactory verification of completed fellowship training in pediatric infectious diseases
- Active, unrestricted medical licensure
- Professional standing confirmation
- An accepted scholarly work product, documented jointly by the fellowship program director and the Scholarship Oversight Committee
Each of these has its own paperwork trail and timing considerations, and missing a documentation step can delay your application cycle by an entire testing window given the biennial schedule. A full walkthrough of these requirements, including how the scholarly work product is typically documented, lives at PID Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Cost of the Credential
Budgeting for this certification means separating one-time initial costs from recurring ones. ABP's published 2026 summer/fall subspecialty fee schedule lists new-applicant regular registration at $2,992, which includes a $750 processing fee, and regular re-registration at $2,242, both in USD. These figures describe that published fee schedule and should be treated as a budgeting reference rather than a locked-in quote for a future Pediatric Infectious Diseases administration, since fees are set on ABP's own cycle.
| Fee Type | Amount (USD) | Notes |
|---|---|---|
| New-applicant regular registration | $2,992 | Includes $750 processing fee |
| Regular re-registration | $2,242 | For candidates re-registering after a prior attempt |
For a fuller breakdown of how these components add up and what else to budget for around a testing cycle, see PID Certification Cost 2026: Complete Pricing Breakdown.
Staying Certified After You Pass
Passing the initial certifying exam is not the end of the process. ABP's continuing certification framework for this subspecialty covers four components: professional standing, lifelong learning and self-assessment, assessment of knowledge, and improvement in practice. According to the PIDS maintenance guide, this runs on five-year cycles requiring 100 total points - at least 40 Part 2 points, at least 40 Part 4 points, and 20 additional points that can come from either category.
MOCA-Peds is ABP's longitudinal knowledge-assessment pathway and is a separate mechanism from the initial certifying exam described throughout this article. If you're preparing for initial certification, keep your study materials distinct from MOCA-Peds question formats - they serve different stages of a career and different assessment structures.
Key Takeaway
Initial certification and maintenance are two different systems with two different point structures. Don't mix MOCA-Peds prep into your first-attempt study plan.
Who Looks for This Credential
Certification in Pediatric Infectious Diseases signals that a physician has completed accredited fellowship training and met ABP's subspecialty standard in this specific clinical area. It's most relevant to academic medical centers, children's hospitals, and pediatric infectious diseases divisions evaluating candidates for attending, consultant, or stewardship-leadership roles. Because the credential requires fellowship completion and a documented scholarly product, it also functions as a marker of research and clinical training depth beyond general pediatrics.

Complete ROI Analysis 2026 weighs the broader return on the time and cost involved.
Building a PID-Specific Study Plan
Generic study techniques - spaced repetition, timed blocks, teach-back review - work, but only when mapped onto this exam's actual weighting. Given that cardiovascular, bone/joint, and urologic infections now carry more weight and antimicrobial principles carry less, a study calendar built for an older outline version will misallocate your time.
Organ-System Infections
- Drill cardiovascular, bone/joint, and urologic infection cases given their increased weighting
- Build differential-diagnosis tables by pathogen and age group
Neonatal, Congenital, and Immunocompromised Host Topics
- Work through neonatal sepsis and congenital infection scenarios
- Review prophylaxis and vaccine-timing rules for immunocompromised patients
Antimicrobial Principles and Prevention/Vaccination
- Cover stewardship and pharmacokinetics at an application level, not just recall
- Reinforce immunization schedules and outbreak-response basics
Full-Outline Review and Timed Practice
- Cycle through all 22 domains using mixed practice sets
- Simulate the half-day, computer-based Prometric format under timed conditions
