- This is the AOBA initial Pediatric Anesthesiology subspecialty written exam: 200 multiple-choice questions, two sections of about 100 questions each.
- Passing requires at least 500 on the AOA 200-800 scaled score, not a raw-percent cutoff.
- Specific Techniques carries 51-55% of the exam and Basic Concepts 20-24%, so together they decide the result.
- Initial exam fee is USD 600; a late surcharge of USD 180 brings the total to USD 780.
Which Credential This Cheat Sheet Covers
This page is a one-screen review of a single credential: the initial Pediatric Anesthesiology Subspecialty Certification offered by the American Osteopathic Board of Anesthesiology (AOBA), part of the American Osteopathic Association (AOA). It is not the American Board of Anesthesiology exam, not the AOBA's primary anesthesiology certification, and not the shorter Osteopathic Continuous Certification (OCC) renewal assessment. Each of those has its own rules, fees and content, and mixing them up is the fastest way to prepare for the wrong test.
If you want the broader picture first, start with our overview of Pediatric Anesthesiology certification or the deeper study guide for passing on your first attempt. The rest of this article is the compressed version: numbers to memorize, domains to prioritize, logistics to confirm.
The Exam at a Glance
| Item | Initial Subspecialty Exam |
|---|---|
| Certifying body | AOBA, within the AOA |
| Format | 200 multiple-choice questions |
| Structure | Two sections of roughly 100 questions, 120 minutes each |
| Active testing time | 4 hours, plus a scheduled 10-minute intermission |
| Total seat time stated by issuer | 4 hours 10 minutes (check-in is additional) |
| Delivery | Remotely proctored through MonitorEDU |
| Passing standard | At least 500 on the 200-800 AOA scaled score |
| Offered | Annually |
| Attempts | Up to three in three years, then petition the board |
Two details matter more than they look. First, the score is scaled, so do not translate 500 into a percentage of questions answered correctly. Second, submitted sections cannot be reopened, which makes pacing and committing to answers part of the skill being tested. For a deeper look at what the scaled score means, see our guide to the Pediatric Anesthesiology passing score.
A current initial-exam pass rate has not been verified, so any number you see quoted elsewhere should be treated with caution. Our pass rate analysis explains what can and cannot be said from available data.
Domain Weights: Where the Points Live
The AOBA publishes eight content categories with percentage ranges. These are official exam content categories, not a preparation curriculum, and the current initial-exam page does not break them into a detailed syllabus. We keep the published ranges as they are rather than inventing midpoints.
| Domain | Published Weight |
|---|---|
| 1. History | 1-3% |
| 2. Basic Concepts | 20-24% |
| 3. Pharmacology | 3-7% |
| 4. Anesthesia Equipment for Pediatrics | 2-6% |
| 5. Monitoring | 2-6% |
| 6. Preoperative Evaluation | 1-5% |
| 7. Anesthetic Procedures & Methods | 4-8% |
| 8. Specific Techniques | 51-55% |
For domain-by-domain commentary, our complete guide to all 8 content areas goes further. One caution: because the AOBA does not publish a sub-outline for the initial exam, do not substitute another board's outline for it.
Specific Techniques: The 51-55% Block
Domain 8: Specific Techniques (51-55%)
This is the exam. More than half the questions will ask how you actually conduct pediatric anesthesia for particular patients and situations, so think in terms of decisions at the bedside rather than isolated facts.
- Expect case-style stems that give age, weight, comorbidity and procedure, then ask for the best induction, airway, maintenance or emergence approach.
- Be ready to reason from physiology to technique: why a neonate, an infant with congenital heart disease and a school-age child with a full stomach each call for a different plan.
- Practice recognizing the safest answer when several options are plausible. Pediatric questions often hinge on a single patient-specific detail.
- Rehearse complication management as a technique too: laryngospasm, difficult airway, hemodynamic collapse and similar events are decision problems, not recall problems.
Because the AOBA has not published a finer breakdown of this heading, build your own topic list from your fellowship case log and your most recent rotations, then weight it toward patient groups you saw least. That gap-first approach is more reliable than assuming the exam mirrors your institution's case mix.
Basic Concepts: The 20-24% Block
Domain 2: Basic Concepts (20-24%)
This is the foundation layer that makes Specific Techniques answerable. Think developmental physiology and the principles that explain why children are not small adults.
- Age-related differences in respiratory, cardiovascular, renal, hepatic and thermoregulatory physiology, and how they change drug behavior and risk.
- Transitional circulation and the physiology of the newborn and premature infant.
- Fluid, electrolyte and metabolic principles as they apply to small patients.
- Airway anatomy and mechanics in infants and children compared with adults.
Basic Concepts questions often look like reasoning problems that quietly depend on a physiologic principle. If you can explain why an infant desaturates quickly or loses heat quickly, you can usually get both the concept question and the related technique question right.
Key Takeaway
Study Basic Concepts and Specific Techniques as one connected system. Every physiology fact you learn should end with the clinical decision it changes.
The Six Small Domains in One Pass
These domains are small individually, but they are not free points, and they tend to be the ones people skip until the final week. A short, structured pass is enough.
History (1-3%)
The smallest slice. A few well-chosen questions on the development of the specialty are possible; give it a brief skim rather than dedicated study blocks.
Pharmacology (3-7%)
Focus on how pediatric pharmacokinetics and pharmacodynamics differ from adult patterns, and on agents commonly used in children. Weight-based reasoning and age-dependent sensitivity are the recurring themes.
Anesthesia Equipment for Pediatrics (2-6%)
Think circuits, airway devices sized for children, vaporizers and ventilators as they relate to small tidal volumes. Know what changes when the patient weighs a few kilograms.
Monitoring (2-6%)
Standard and advanced monitors, their limitations in small patients, and how to interpret what they show. Know when a number is trustworthy and when it is an artifact.
Preoperative Evaluation (1-5%)
Risk assessment, fasting principles, evaluation of children with complex medical histories, and the decision of whether a patient is optimized or should be delayed.
Anesthetic Procedures & Methods (4-8%)
The largest of the small domains. Regional and other procedural methods and their pediatric-specific considerations belong here, and these overlap naturally with Specific Techniques.
Eligibility, Fees and Attempt Limits
Who can apply
- Current primary AOBA certification.
- Completion of an ACGME-accredited Pediatric Anesthesiology fellowship, with completion verification sent directly by the fellowship program.
- At least one year of specialist practice before applying.
Our requirements guide walks through qualification step by step.
What it costs
| Fee | Amount |
|---|---|
| Initial exam fee | USD 600 |
| Late surcharge | USD 180 |
| Total if late | USD 780 |
The late surcharge is the easiest money to save: it is purely a function of missing the regular deadline. For the full pricing picture, including what to budget around the exam, see the certification cost breakdown.
Attempts and accommodations
- Up to three attempts within three years. After a third failure, you must petition the board.
- Accommodations are requested with the application, and documentation is due at least 30 days before the exam.
Remote Exam-Day Checklist
The exam is remotely proctored, which makes logistics part of your preparation. Failing a system check on test day is an avoidable disaster.
- Private room: secure, quiet and compliant with the proctoring rules.
- Two devices: a computer plus a mobile device.
- Technical checks: run the system checks ahead of time, not the morning of the exam.
- Webcam and microphone: working and positioned as instructed.
- Secure browser: installed and tested.
- Identification: government ID and your AOA candidate ID.
- Identity and room checks: allow time for these; check-in is additional to the 4 hours 10 minutes of seat time.
The AOA supplies an online calculator, scratch pad and laboratory values inside the exam, so you do not need to memorize reference ranges purely for recall. The platform also offers preparation resources, but the generic platform practice test is not specialty-specific. It is useful for learning the interface, not for gauging your pediatric anesthesia knowledge. For subject-matter practice, use specialty-focused questions such as those on our main practice test site.
After You Pass: Ten Years of OCC
Certification is valid for ten years, conditional on Osteopathic Continuous Certification (OCC), which includes licensure, CME, cognitive assessment and practice improvement. For time-limited diplomates in the 2025-2027 cycle, the CME requirement is 75 credits per three years, including 18 Category 1-A or 1-B credits, plus one quality-improvement activity attestation per three-year CME cycle.
Pediatric subspecialty OCC also keeps a separate annual written assessment, eligible within three years before certificate expiration. That is a different exam from the initial one: it has 100 questions, is described as a 2-hour-30-minute exam with one scheduled 10-minute break, and carries a USD 750 fee with a USD 225 late surcharge. Do not confuse its duration or fee with the initial exam's.
If you are weighing whether the long-term commitment pays off, read our ROI analysis and the salary guide.
The Deadline Discrepancy to Verify
Two sources describe the 2026 timeline differently, and we are deliberately not reconciling them.
- The AOBA certification page states a general rule: applications open six months before the exam, with regular and final deadlines 60 and 30 days before the testing window.
- An American Osteopathic College of Anesthesiologists (AOCA) announcement lists June 14 and July 14 deadlines for an August 20, 2026 subspecialty date.
Allocating Study Time by Weight
A generic schedule is less useful than one tied to the blueprint. Here is a simple, weight-driven sequence that front-loads the heaviest domains.
Basic Concepts (20-24%)
- Rebuild developmental physiology first, because it makes everything else easier to reason about.
- Link each principle to a clinical consequence.
Specific Techniques (51-55%)
- Spend the largest share of your time here, working case by case across patient ages and conditions.
- Revisit weak patient groups repeatedly rather than finishing one topic at a time.
Small domains and timed practice
- Cover Pharmacology, Equipment, Monitoring, Preoperative Evaluation, Procedures & Methods and History in short blocks.
- Finish with two-section timed practice that mimics 120-minute sections and no reopening of submitted answers.
For a full preparation plan, see the study guide, and use the practice question bank for timed sets.
FAQ
It covers the initial Pediatric Anesthesiology Subspecialty Certification written exam from the American Osteopathic Board of Anesthesiology. It does not cover the American Board of Anesthesiology exam, primary AOBA certification or the separate OCC renewal assessment.
You need at least 500 on the AOA 200-800 scaled-score range. This is a scaled score, not a raw-percent threshold, so you cannot convert it into a fixed number of correct answers.
There are 200 multiple-choice questions in two sections of about 100 questions, each 120 minutes. That is 4 hours of active testing plus a scheduled 10-minute intermission, or 4 hours 10 minutes of seat time as stated by the issuer, with check-in additional.
Specific Techniques is the largest at 51-55%, followed by Basic Concepts at 20-24%. The remaining six domains are each far smaller, so prioritize the two largest while still covering the rest.
You may attempt it up to three times in three years. After a third failure, you must petition the board before further attempts.
Keep this sheet beside your study plan: two heavy domains, a scaled passing score, a limited number of attempts, and a remote-proctoring checklist you should rehearse well before test day.
