Exam Overview and Why Domains Matter
The AOA Subspecialty Certification in Sports Medicine (CAQ) written examination is administered by the American Osteopathic Conjoint Sports Medicine Examination Committee (AOCSMEC), not by any professional society. The exam itself is 200 single-best-answer multiple-choice questions delivered in a half-day sitting, and it is scored on a 200-800 scale with a passing threshold of 500. Every question you see on exam day is drawn from one of five published content domains, so understanding how those domains are weighted is the single most useful piece of information you can have before you build a study plan.
Domain weighting is not trivia - it is a direct map of where the committee expects you to spend your preparation time. If you want the full mechanics of eligibility, testing windows, and fees before diving into content, see our companion pieces on Sports Medicine CAQ requirements and exam dates and scheduling. This guide focuses exclusively on what is actually tested and how much of the exam each area represents.
The Five Content Domains at a Glance
The current 2026 outline for the AOA Subspecialty Certification in Sports Medicine (CAQ) uses five categories. Basic Science and Diagnostics are jointly the largest at 23% each, followed by Injury Management and Prevention at 22%, Treatment at 20%, and Medical Issues at 12%. Within Treatment, osteopathic principles and practice and osteopathic manipulative treatment are broken out as distinct 4% subtopics rather than merged into a single line item - a detail that trips up candidates who assume OMT knowledge is a minor add-on.
| Domain | Weight | Relative Size |
|---|---|---|
| Basic Science | 23% | Largest (tied) |
| Diagnostics | 23% | Largest (tied) |
| Injury Management and Prevention | 22% | Near-largest |
| Treatment (incl. OPP 4% and OMT 4%) | 20% | Moderate |
| Medical Issues | 12% | Smallest |
Notice that the top three domains - Basic Science, Diagnostics, and Injury Management and Prevention - together account for roughly two-thirds of the exam. That should shape how you allocate weeks, not just days, in your prep schedule. For a broader look at how difficult candidates find this weighting in practice, see How Hard Is the Sports Medicine CAQ Exam?.
Domain 1: Basic Science (23%)
Basic Science
This domain tests the foundational science that underlies everything else on the exam. Expect questions on musculoskeletal anatomy as it relates to sport-specific injury patterns, exercise physiology, biomechanics of movement and gait, and the physiologic response to training loads.
- Anatomy of commonly injured structures (ligaments, tendons, growth plates)
- Exercise physiology, including cardiovascular and metabolic adaptation
- Biomechanics of throwing, running, and cutting sports
- Growth and development considerations in the pediatric and adolescent athlete
Because Basic Science is tied for the highest weight, questions here are not superficial recall items - they are frequently framed as applied vignettes where you must connect a mechanism of injury back to an anatomic or physiologic principle. Candidates who skip straight to clinical management topics often underperform in this domain because they never anchored the "why" behind the pathology.
Domain 2: Diagnostics (23%)
Diagnostics
Diagnostics carries equal weight to Basic Science, and it covers the full diagnostic workup of the athlete: history and physical examination findings, special orthopedic tests, imaging interpretation, and laboratory or point-of-care testing relevant to sports medicine.
- Physical exam maneuvers and their sensitivity/specificity in clinical scenarios
- Plain film, MRI, and ultrasound findings for common sports injuries
- Sideline and pre-participation evaluation decision-making
- Interpreting cardiac screening findings relevant to athlete clearance
Diagnostics questions often present a clinical stem with an exam finding or imaging description and ask you to identify the next best step, not just the diagnosis. This distinction matters when you're building practice question sets - you need repetitions that force a decision, not just recognition. Our Sports Medicine CAQ study guide walks through how to structure that kind of applied review.
Key Takeaway
Because Basic Science and Diagnostics together make up 46% of the exam, weak performance in either one is difficult to compensate for elsewhere - treat these as your non-negotiable core review blocks.
Domain 3: Injury Management and Prevention (22%)
Injury Management and Prevention
This domain sits just below the top two in weight and covers the practical management side of sports medicine: acute injury care, return-to-play decision-making, and the prevention strategies that reduce recurrence and long-term risk.
- Acute management of fractures, dislocations, and soft-tissue injuries
- Concussion management and graduated return-to-play protocols
- Heat illness, hydration, and environmental injury prevention
- Injury-prevention programming for high-risk sports and populations
Because this domain blends acute care with longer-term prevention strategy, expect questions that span the timeline of an injury - from sideline decision to season-long rehabilitation planning. This is also where sideline coverage experience (or lack of it) tends to show up most clearly in practice exam performance.
Domain 4: Treatment (20%)
Treatment
Treatment covers definitive management once a diagnosis and initial injury plan are established, including rehabilitation principles, pharmacologic management, procedural interventions, and the osteopathic-specific subtopics.
- Rehabilitation phases and criteria for progression
- Pharmacologic considerations, including NSAID and analgesic use in athletes
- Injection and procedural indications common in sports medicine practice
- Osteopathic principles and practice (4% subtopic)
- Osteopathic manipulative treatment technique and indications (4% subtopic)
Do not overlook the two osteopathic subtopics simply because each is only 4% individually. Combined, OPP and OMT represent 8% of the total exam - comparable in size to some entire domains on other certification exams. Candidates who trained primarily in allopathic settings during fellowship should specifically shore up OMT technique indications before test day.
Domain 5: Medical Issues (12%)
Medical Issues
The smallest domain by weight, Medical Issues covers the non-musculoskeletal medical conditions that intersect with athletic participation: cardiac, pulmonary, dermatologic, infectious, and endocrine issues that affect clearance and in-season management.
- Cardiac conditions relevant to sudden cardiac death risk and screening
- Exercise-induced bronchospasm and asthma management in athletes
- Infectious disease and skin conditions in contact-sport settings
- Endocrine and nutritional issues, including disordered eating in athletes
At 12%, Medical Issues should receive proportionally less study time than the other four domains - but it is still worth roughly 24 questions on a 200-question exam, which is not a number you can afford to ignore entirely.
Mapping the Domains to a Study Timeline
Rather than dividing your prep time evenly across five domains, build your schedule around the actual point values. A practical approach: spend the first two blocks of your timeline on Basic Science and Diagnostics since they are tied for the highest weight and often require the deepest foundational review, then move into Injury Management and Prevention and Treatment, and close with a focused pass on Medical Issues plus full-length practice exams.
Basic Science
- Review anatomy, biomechanics, and exercise physiology by sport and injury type
- Build recall of growth-plate and pediatric-specific considerations
Diagnostics
- Drill physical exam and imaging vignettes with a "next best step" framing
- Review pre-participation and cardiac clearance decision trees
Injury Management and Prevention, then Treatment
- Work through acute-care and return-to-play scenarios
- Review rehabilitation phases, OPP, and OMT indications together
Medical Issues and Full Reviews
- Cover cardiac, pulmonary, and endocrine topics at proportional depth
- Run full-length timed practice sets across all five domains
This kind of weighted timeline is only useful if you're also tracking accuracy by domain, not just overall score. A generic spaced-repetition schedule that ignores the 23/23/22/20/12 split will waste hours on the smallest domain and shortchange the two largest ones. If you want a condensed reference to keep next to your notes during this phase, our Sports Medicine CAQ cheat sheet summarizes the five domains and their weights on a single page, and you can pressure-test your recall with timed sets on our practice test platform.
Format, Registration, and Scoring Mechanics
Knowing the domains is only half the picture - you also need to understand how the exam is delivered and scored so your practice conditions match test day. The 2026 examination is delivered online with remote proctoring, and AOA's remote-exam preparation specifies the MonitorEDU SecureBrowser for this purpose. The standard 2026 examination fee is $1,100, and eligibility requires active AOA primary board certification, an active medical license in one of the 50 states, good ethical standing, and completion of a one-year AOA- or ACGME-approved sports medicine fellowship with documentation and program-director support.
There is a published eligibility window of six years after fellowship completion, and candidates supported for early examination after at least nine fellowship months will have results withheld until training documentation is finalized. For the full cost breakdown including this $1,100 fee and other associated expenses, see Sports Medicine CAQ Certification Cost 2026.
Passing requires a scaled score of at least 500 on a 200-800 scale, calculated across the full 200-question exam rather than as five separate pass/fail domain scores. That means a stronger performance in Basic Science can offset a slightly weaker showing in Medical Issues, but it does not excuse neglecting any domain outright given how the weights are distributed. For a deeper explanation of exactly how that scaled score works, read Sports Medicine CAQ Passing Score 2026.
