What the Exam Actually Is
The Certification in Pediatric Pulmonology is the American Board of Pediatrics (ABP) subspecialty credential for pediatricians who have completed fellowship training in pediatric lung disease. It is a computer-based, multiple-choice examination of approximately 200 questions, administered at Prometric testing centers. It is not a pulmonary function technologist credential, not a respiratory therapy exam, and not an adult pulmonary or critical care board. Everything on it is framed around infants, children, and adolescents.
That framing matters for how you study. Adult pulmonary references will get you partway through asthma and sleep-disordered breathing, but large parts of the exam live in territory adult texts barely touch: neonatal respiratory disorders, congenital airway and lung malformations, cystic fibrosis across the lifespan of a pediatric patient, and the developmental physiology that explains why children fail differently than adults. If you want a broader orientation before diving in, our overview of Pediatric Pulmonology certification and the explainer on what Pediatric Pulmonology certification is cover the basics; this guide assumes you are already committed and want a plan.
Questions are typically clinical vignettes: a patient presents with a history, exam findings, and sometimes a pulmonary function result, imaging description, or sweat chloride value, and you select the best next step, most likely diagnosis, or underlying mechanism. Expect to interpret data rather than recall isolated facts.
Which Outline Applies to You
One of the most common preparation errors is studying against the wrong content outline. The current ABP Pediatric Pulmonology initial-certification content outline takes effect November 1, 2026, and it applies to the upcoming November 5, 2026 initial-certification examination. The October 2025 date associated with subboard approval is not the effective date, so do not treat it as the version cutoff.
The outline has 19 domains with approximate published weights totaling 100%. Versions may vary slightly, so always pull the PDF directly rather than relying on a third-party summary, including this one. The official sources are the ABP Pulmonology content outline, the subspecialty outline directory, and the exam dates and fees page. For scheduling detail, see our guide to Pediatric Pulmonology exam dates.
Reading the 19 Domains as a Study Budget
The published weights are the closest thing to an official blueprint of where points come from. Treat them as a budget: allocate study hours roughly in proportion, then adjust for your own weak spots. The full list, with our complete walkthrough in the 19 content areas guide:
| Domain | Approx. Weight |
|---|---|
| Asthma | 9% |
| Common Signs and Symptoms | 8% |
| Core Principles of Pulmonary Diagnosis and Monitoring Techniques | 8% |
| Lung Development and Physiology | 6% |
| Respiratory Infections | 6% |
| Cystic Fibrosis (CF) | 6% |
| Respiratory Disorders of the Neonate and Infant | 5% |
| Congenital and Acquired Malformations of the Airways and Lungs | 5% |
| Restrictive Disease | 5% |
| Respiratory Failure | 5% |
| Interstitial Lung Disease | 5% |
| Other Disorders of the Respiratory System | 5% |
| Non-CF Bronchiectasis | 4% |
| Sleep-Disordered Breathing and Control of Breathing Disorders | 4% |
| Pulmonary Vascular and Lymphatic Diseases | 4% |
| Lung Disease Associated with Systemic Disorders | 4% |
| Environmental Injuries and Exposures (Acute and Chronic) | 4% |
| Core Knowledge in Scholarly Activities and Health Equity | 4% |
| Respiratory System Under Stress | 3% |
Two things stand out. First, the distribution is fairly flat: no domain exceeds 9%, and the bottom of the list is 3%. You cannot pass by mastering asthma and CF alone. Second, two of the three heaviest domains (Common Signs and Symptoms, and Core Principles of Diagnosis and Monitoring) are not disease categories at all. They reward clinical reasoning and test interpretation, which is where fellowship experience either pays off or leaves gaps.
High-Yield Content in the Heaviest Domains
Asthma (9%)
The largest published domain, and the one where you are most likely to feel overconfident. Questions go beyond stepwise therapy into phenotyping, diagnostic mimics, and management of difficult disease.
- Severity versus control, and how each drives therapy changes
- Biologic therapy selection based on phenotype and comorbid atopy
- Differentiating asthma from vocal cord dysfunction, tracheomalacia, and other airway causes of wheeze
- Interpreting spirometry and bronchodilator response in the evaluation
Common Signs and Symptoms (8%)
Symptom-first vignettes: chronic cough, wheeze, stridor, hemoptysis, tachypnea, cyanosis, clubbing, chest pain, and exercise intolerance. The task is building a sensible differential and choosing the discriminating next test.
- Chronic wet cough in a child and the pathway from protracted bacterial bronchitis to CF and ciliary disorders
- Stridor timing (inspiratory versus biphasic) and what it localizes
- When hemoptysis points toward vascular, infectious, or structural causes
Core Principles of Pulmonary Diagnosis and Monitoring Techniques (8%)
This is the interpretation domain: pulmonary function testing, imaging, bronchoscopy and lavage findings, polysomnography, blood gases, and exhaled or sweat-based testing.
- Recognizing obstructive, restrictive, and mixed patterns, and the limits of testing in young children
- Choosing between chest radiography, CT, and other modalities given radiation and yield
- Reading bronchoalveolar lavage results and what a given cell pattern suggests
Domains Candidates Underestimate
Mid-weight domains are where well-prepared candidates quietly lose points, because they feel peripheral to daily clinic work.
Lung Development and Physiology (6%)
Embryologic stages, alveolarization timing, surfactant biology, and the mechanics of the infant chest wall underpin questions across several other domains. A malformation question, a neonatal question, and a restrictive disease question can all hinge on the same developmental fact. Expect to apply concepts such as compliance, resistance, and ventilation-perfusion relationships to vignettes rather than recite definitions.
Cystic Fibrosis (6%) and Non-CF Bronchiectasis (4%)
CF is a core fellowship topic, but the exam's angle is often current care: modulator therapy implications, microbiology and eradication strategies, nutritional and pancreatic management, and complications such as CF-related diabetes and liver disease. Pair it with non-CF bronchiectasis, where the key skill is working up underlying causes, including primary ciliary dyskinesia, immunodeficiency, and recurrent aspiration.
Neonatal and Congenital Content (5% each)
Respiratory Disorders of the Neonate and Infant, plus Congenital and Acquired Malformations of the Airways and Lungs, together carry as much weight as the top domain. Review bronchopulmonary dysplasia phenotypes and long-term outcomes, congenital diaphragmatic hernia, congenital pulmonary airway malformation, sequestration, and laryngeal and tracheal anomalies. Many candidates who trained in busy outpatient settings find these the thinnest part of their recall.
Scholarly Activities and Health Equity (4%)
This domain is unusual and easy to dismiss. It covers research literacy, quality improvement, and equity in respiratory care. Interpreting study design, bias, and statistical concepts is learnable in a few focused sessions, and it is among the most efficient points you can bank. Environmental exposures and disparities in asthma burden also connect it to the Environmental Injuries and Exposures domain.
Scaled Scoring and What the Pass Rate Means
The passing standard is a scaled score of 180 on a 1-300 scale. That is not a raw percentage, so you cannot convert it into "I need X questions right," and chasing a mythical percentage target is unproductive. Our explainer on the Pediatric Pulmonology passing score goes deeper on scaling.
The latest verified first-time national pass rate is 73% in 2024, compared with 68% in 2022, as reported in a 2026 primary paper citing ABP data. Read that carefully: it describes first-time takers nationally, not your personal odds, and two data points do not establish a trend. It does suggest most well-trained candidates pass, which should calm anxiety while still justifying serious preparation, since roughly one in four first-time takers in the most recent year did not. For context on interpreting these numbers and how demanding the test feels, see the pass rate analysis and the difficulty guide.
Registration, Fees, and Eligibility Checks
The official indexed regular fee is $2,992, which includes a $750 processing component. Build that into your planning early; our certification cost breakdown covers budgeting around it, and the ROI analysis helps frame the investment against career outcomes, including earnings and job prospects.
Traditional eligibility rests on a medical or osteopathic degree, general pediatrics certification, completion of a three-year subspecialty fellowship, and scholarly requirements. Two items need direct ABP confirmation rather than assumption: current license and attestation details, and whether the announced new training model applies to your pathway. Read the full requirements guide and then verify with the Board before you invest in a test date.
After you certify, continuing certification runs on a five-year cycle, using either MOCA-Peds or an examination pathway. That is worth knowing now because the knowledge you build for the initial exam is the foundation you will maintain.
A Domain-Sequenced Study Schedule
Generic study techniques matter far less than sequencing. The logic below front-loads the foundational and interpretive material that feeds everything else, then moves through organ-system disease, and reserves the final weeks for integration. Adjust the length to your timeline; the order is the point.
Foundations and Diagnostics
- Lung Development and Physiology: embryology, mechanics, gas exchange
- Core Principles of Diagnosis and Monitoring: PFTs, imaging, bronchoscopy, polysomnography, blood gases
Airway and Symptom Reasoning
- Asthma in depth, including biologics and mimics
- Common Signs and Symptoms: cough, wheeze, stridor, hemoptysis pathways
Infection, CF, and Bronchiectasis
- Respiratory Infections
- Cystic Fibrosis and Non-CF Bronchiectasis, including ciliary and immune workups
Neonatal, Congenital, and Failure
- Neonatal and infant disorders, malformations of airways and lungs
- Respiratory Failure and Respiratory System Under Stress
Parenchymal, Vascular, and Systemic
- Restrictive Disease and Interstitial Lung Disease
- Pulmonary Vascular and Lymphatic Diseases, and Lung Disease Associated with Systemic Disorders
Sleep, Exposures, Scholarship, and Integration
- Sleep-Disordered Breathing and Control of Breathing Disorders; Environmental Injuries and Exposures
- Scholarly Activities and Health Equity, Other Disorders, then mixed review of weak areas
Revisit the heaviest domains (Asthma, Common Signs and Symptoms, Diagnostic Principles) in your final review pass even though you studied them early, since they carry the most points and are most likely to appear in multi-step vignettes. A condensed reference like the Pediatric Pulmonology cheat sheet works well for those last-week refreshers.
Practicing the Right Way for ABP-Style Questions
Because the exam is vignette-driven, passive reading will not prepare you the way question practice does. Work timed blocks that mimic a 200-question pace, then spend more time reviewing explanations than answering. When you miss a question, classify the reason: a knowledge gap, a misread of the stem, a data-interpretation error, or a second-guessing slip. Each demands a different fix.
Key Takeaway
Tag every missed practice question to one of the 19 domains. After a few hundred questions, your error log reveals which domains are actually costing you points, which is more reliable than your sense of which topics feel hard. Then redirect study hours there.
Use our Pediatric Pulmonology practice tests to build that error log early, and return to the practice question bank in the final weeks for timed, mixed-domain sets. If you want the full study-plan companion to this article, our main Pediatric Pulmonology study guide collects the planning resources in one place.
