What the AOBOS Orthopedic Sports Medicine Exam Actually Tests
The initial Certification in Orthopedic Sports Medicine written examination is administered by the American Osteopathic Board of Orthopedic Surgery (AOBOS), part of the American Osteopathic Association. This is a subspecialty examination that sits on top of primary orthopedic surgery certification - it is not the ABOS pathway, it is not a primary-care sports medicine CAQ, and it is not the same instrument as the primary AOBOS Part I exam or the annual OCC examination. If you're comparing prep materials or discussion-board advice, confirm the source is talking about this specific AOBOS subspecialty exam, because several credentials share similar naming.
Format-wise, the exam consists of 200 multiple-choice questions divided into two 100-question sections. Each section runs 120 minutes, giving candidates 4 hours of total answering time, plus an optional 10-minute scheduled break between sections - for a total seat time of 4 hours 10 minutes. There is no essay or oral component at this stage; every question is scored objectively against the published blueprint.
If you're still mapping out what this credential covers before diving into logistics, our overview on What Is Orthopedic Sports Medicine? and the companion piece on Orthopedic Sports Medicine Certification are useful starting points.
Eligibility and the 2026-2028 Limited Pathway
Admission to sit the exam is permitted immediately after completing a minimum one-year ACGME-accredited sports medicine fellowship, provided you have completion verification, active U.S. medical licensure, and adherence to the AOA Code of Ethics. Notably, exam admission does not require you to already hold your primary AOBOS orthopedic surgery certification or to have logged practice years - those come later, at the certification-award stage.
For 2026, 2027, and 2028 only, AOBOS has opened a limited pathway for qualifying active AOBOS diplomates who fall outside the ordinary eligibility windows but who completed an ACGME-accredited or AOA-approved sports medicine fellowship. If you trained years ago and assumed you'd missed your window, this limited pathway is worth investigating before you rule out sitting the exam.
Full certification award - as opposed to simply sitting the exam - layers on additional requirements: primary AOBOS orthopedic surgery certification, at least two years of active orthopedic sports medicine practice, full operating privileges, and a consecutive 12-month case log containing at least 115 operative cases (including at least 75 involving arthroscopy) plus 10 nonoperative cases. For the complete breakdown of who qualifies and when, see Orthopedic Sports Medicine Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Key Takeaway
You can sit the written exam right after fellowship, but you cannot receive full certification until you've logged two years of practice and the 115/75/10 case-mix requirement - plan your case log tracking from day one of practice.
Registration, Fees, and Key 2026 Dates
The initial examination fee is $3,000. For 2026, the application window runs March 25 through August 25, and the exam itself is scheduled for September 25, 2026. Missing the application window means waiting for the next cycle, so mark the March 25 opening date now if you're targeting this year's sitting.

The Seven Content Domains
The blueprint AOBOS publishes is organized into seven categories, most recently reviewed September 22, 2026. Each domain carries a published percentage range rather than a fixed midpoint or exact allocation - so treat these as guidance on relative emphasis, not a precise question count per topic. For a deep dive into each domain's subtopics and likely question styles, see Orthopedic Sports Medicine Exam Domains 2026: Complete Guide to All 7 Content Areas.
Domain 1: Lower Extremity - Hip (10-14%)
Covers hip impingement, labral pathology, and both operative and nonoperative hip management in the athlete.
- Femoroacetabular impingement recognition and surgical indications
Domain 2: Lower Extremity - Knee (15-21%)
The single largest domain by upper bound. Expect heavy coverage of ligament injuries, meniscal pathology, and patellofemoral disorders.
- ACL/PCL reconstruction principles and postoperative decision-making
Domain 3: Lower Extremity - Foot and Ankle (11-17%)
Focuses on ankle instability, syndesmotic injuries, and athlete-specific foot pathology.
- Lateral ankle ligament repair versus nonoperative bracing decisions
Domain 4: Upper Extremity - Shoulder (12-18%)
Rotator cuff, labral, and instability pathology dominate this domain, alongside return-to-throwing considerations.
- Shoulder instability classification and stabilization approach selection
Domain 5: Upper Extremity - Elbow (10-16%)
Covers ligament injury in throwing athletes and elbow arthroscopy indications.
- UCL injury management across operative and nonoperative pathways
Domain 6: Upper Extremity - Wrist and Hand (12-14%)
The narrowest range of the seven domains, but still a meaningful share of the exam.
- Athlete-specific wrist ligament and TFCC injury patterns
Domain 7: Non-Operative (11-17%)
Spans concussion management, rehabilitation principles, pharmacologic considerations, and medical management of the athlete outside the operating room.
- Return-to-play protocols and nonsurgical treatment algorithms
Remote Testing Logistics
AOBOS remote proctoring follows the AOA MonitorEDU/PARADIGM arrangement. Candidates testing remotely need a private, distraction-free space, valid identification, a properly configured secure browser, a supported computer, and mobile device monitoring during the session. One detail that surprises first-time candidates: AOBOS permits the use of whiteboards during the exam, which can be useful for sketching anatomic relationships or working through case logic on questions involving imaging interpretation.
Because remote-testing setup issues can eat into your available time on exam day, run through the technical requirements at least a week ahead rather than the night before.
How the Scaled Score Works
Passing requires a scaled score of at least 500 on the AOA's 200-800 scale. This is not a simple percent-correct threshold - the scaling process accounts for question difficulty across the exam form, which means two candidates answering a different number of items correctly on different forms can both land above the passing line. For a full explanation of how the scaled score is calculated and what it means for your preparation strategy, read Orthopedic Sports Medicine Passing Score 2026: Exactly What You Need to Pass. If you're weighing how demanding this exam is relative to your clinical background, How Hard Is the Orthopedic Sports Medicine Exam? Complete Difficulty Guide 2026 breaks down the format factors that affect difficulty.
A Domain-Based Study Timeline
Generic study techniques - spaced repetition, timed practice blocks, and active recall - work best here when they're mapped directly onto the seven-domain blueprint rather than applied as a one-size-fits-all schedule. Below is a sample allocation built around the domain weight ranges rather than an arbitrary calendar.
Knee and Hip
- Start with Knee given its 15-21% range, then move to Hip (10-14%)
- Build case-based recall around ACL/meniscal decision trees
Shoulder and Elbow
- Cover Shoulder's 12-18% range in depth, then Elbow at 10-16%
- Focus practice questions on throwing-athlete pathology
Foot/Ankle, Wrist/Hand, Non-Operative
- Work through the remaining three domains together
- Emphasize Non-Operative topics like concussion and rehab protocols
Full-Length Timed Review
- Simulate two 100-question, 120-minute sections back to back
- Practice the optional 10-minute break to build pacing comfort
Run timed practice sections through our practice test platform so the two-section, 200-question rhythm feels familiar before exam day. A quick-reference companion for last-minute review is the Orthopedic Sports Medicine Cheat Sheet 2026: One-Page Review of Must-Know Facts.
After the Exam: Certification and OCC
Passing the written exam is only one milestone. Full certification additionally requires holding primary AOBOS orthopedic surgery certification, two years of active orthopedic sports medicine practice, full operating privileges, and that consecutive 12-month case log of 115+ operative cases (75+ with arthroscopy) plus 10 nonoperative cases.
Once certified, ongoing status depends on Osteopathic Continuous Certification (OCC), which includes active licensure and practice-performance improvement components. For the 2025-2027 CME cycle, time-limited and voluntary-OCC diplomates need 60 credits over three years, including 15 Category 1-A credits.
A distinct requirement is the sports subspecialty longitudinal assessment: 20 annual, untimed, open-book, article-based questions with an 80% passing criterion and a $270 annual fee. This replaces participation in the primary orthopedic surgery longitudinal assessment. New subspecialty diplomates certified after January 1, 2024 get one full calendar year before they must begin participating.
Thinking about whether the full commitment - exam plus ongoing OCC and longitudinal assessment fees - pays off for your career trajectory? See Is the Orthopedic Sports Medicine Certification Worth It? Complete ROI Analysis 2026 and Orthopedic Sports Medicine Jobs for how the credential factors into hiring conversations.

Key Takeaway
Start your operative and nonoperative case log the day you begin practice - the consecutive 12-month, 115/75/10 requirement means gaps or missed documentation can delay certification well beyond the two-year practice minimum.
