What the Hand Surgery CAQ Actually Is
"Hand Surgery CAQ" is the working label for what the American Osteopathic Association now officially calls Subspecialty Certification in Hand Surgery. The older "Certificate of Added Qualifications" language persists in conversation, job postings, and search queries, which is why you will still see it everywhere. If you want the terminology unpacked from several angles, our companion pieces on the Hand Surgery CAQ meaning and what Hand Surgery CAQ stands for cover the naming history in more detail.
In practical terms, the credential is a board-level recognition that an orthopedic surgeon has completed formal hand fellowship training, accumulated a documented operative experience in hand surgery, and passed a standardized examination in the discipline. It sits on top of primary orthopedic certification rather than replacing it. That layering is the single most important concept to grasp: you do not earn this credential in isolation, and the award itself depends on holding the right primary certification first.
Who Certifies It and Why It Matters
The certifying body is the American Osteopathic Board of Orthopedic Surgery (AOBOS), operating under the American Osteopathic Association's board certification structure. AOBOS sets the eligibility rules, maintains the content blueprint, and determines the passing standard. The credential therefore signals subspecialty competence within the osteopathic orthopedic pathway specifically.
Why does that matter to a working surgeon? Three reasons come up repeatedly:
- Credentialing and privileges. Hospitals and surgery centers often tie hand-specific privileges to documented subspecialty qualification.
- Referral identity. Referring physicians and patients increasingly look for formal subspecialty recognition when directing complex upper-extremity problems.
- Professional standing. Certification is a visible, verifiable marker that you have met a defined standard beyond general orthopedic practice.

Eligibility: Fellowship, Cases, and Practice Requirements
The eligibility pathway is more demanding than simply finishing a fellowship and registering. There are two distinct gates: the requirements to sit for the exam, and the additional requirements to be awarded the certification once you pass.
Requirements to sit for the exam
- Completion of a one-year ACGME-accredited hand fellowship, with verification.
- Active licensure meeting board standards.
- Satisfaction of the board's ethics and professional-conduct requirements.
Additional requirements for the award
Passing the exam alone does not complete the process. To be awarded the certification, the candidate must also demonstrate:
- Qualifying AOBOS or AOBS primary certification in place.
- Two years of active practice.
- Appropriate hospital or surgical privileges.
- 125 major hand cases logged within a consecutive 12-month period, falling within a three-year window.
- A hand operative caseload making up at least 50% of total operative volume.
Our dedicated guide to Hand Surgery CAQ requirements walks through each prerequisite and how to document it.
Exam Format and Remote Delivery
The examination is built around a single, compact format:
| Feature | Detail |
|---|---|
| Question count | 100 questions |
| Question type | Type A single-best-answer multiple choice |
| Time allowed | Two hours, one continuous block |
| Scheduled break | None |
| Passing score | 500 on a 200-800 scale |
| Delivery | Remote, with MonitorEDU proctoring |
The pace works out to roughly 72 seconds per question, which is tight for clinically dense hand-surgery stems. Type A format means you choose the one best answer from the options, so the skill being tested is discrimination between plausible choices, not recall of isolated facts. Expect vignettes that ask you to decide on the most appropriate next step, the most likely diagnosis, or the preferred treatment among reasonable alternatives.
Remote proctoring logistics
The exam is delivered remotely through MonitorEDU proctoring, and AOA guidance references the PARADIGM practice interface, which is worth exploring so the testing environment is not unfamiliar on exam day. The remote setting requires a private space, passing equipment checks beforehand, and use only of authorized tools such as an approved whiteboard. We have not verified any open-book or adaptive-testing component, so plan on a conventional closed-book, fixed-length exam.
Key Takeaway
With no scheduled break across a two-hour block, treat the exam as a sustained-focus event. Practice complete 100-question sets under timed, uninterrupted conditions so the format itself is not a surprise.
For the scoring side of this, see our breakdown of the Hand Surgery CAQ passing score, and for scheduling context, the Hand Surgery CAQ exam dates page. Note that the September 25, 2026 sitting has already passed, so confirm the next available window directly with the board.
The 12-Category Blueprint
AOBOS publishes an undated 12-category content blueprint that expresses each category as a range of the exam rather than a fixed percentage. That means the real distribution can shift slightly between forms, but the ranges tell you precisely where to invest your hours.
| Domain | Weight |
|---|---|
| Arthritis | 13-15% |
| Nerve | 12-14% |
| Infection | 11-13% |
| Joint | 10-12% |
| Osseous | 9-11% |
| Tendon | 8-10% |
| Tumor | 7-9% |
| Microsurgery | 6-8% |
| Vascular | 5-7% |
| Amputation | 3-5% |
| Pediatrics | 3-5% |
| Soft Tissue | 1-3% |
The top three categories alone represent a large share of the exam, and the top four or five account for the majority. Our full domains guide goes deeper on each area; here is what candidates should have in hand for the biggest ones.
Arthritis (13-15%)
The heaviest category. Expect questions spanning the inflammatory and degenerative conditions that affect the hand and wrist.
- Osteoarthritis patterns at the thumb carpometacarpal joint, DIP, and PIP, and the logic behind operative versus nonoperative choices
- Inflammatory arthritis, including rheumatoid disease, and the tendon and joint consequences that follow
- Wrist arthritis patterns and the salvage options matched to stage of disease
Nerve (12-14%)
Peripheral nerve questions reward a clean grasp of anatomy, examination findings, and timing.
- Compression neuropathies at the carpal tunnel, cubital tunnel, and other common sites, with diagnostic and treatment reasoning
- Nerve injury classification, repair timing, and the role of grafts and transfers
- Distinguishing the findings that localize a lesion to a specific level
Infection (11-13%)
A category where decisive, time-sensitive management is exactly what Type A questions probe.
- Flexor tenosynovitis, felon, paronychia, deep-space infection, and septic arthritis
- Bite wounds and organisms that shape antibiotic selection
- Indications for urgent drainage versus a trial of conservative therapy
The smaller categories should not be ignored just because they carry less weight. Joint, Osseous, and Tendon together form another substantial block, and categories like Microsurgery, Tumor, and Vascular often contain high-yield, narrowly testable concepts. Even the lightest category, Soft Tissue at 1-3%, can contribute a few questions that are easy to secure with brief review.
Fees and Registration Mechanics
The initial fee is $3,000. That figure covers the initial certification process as published by the board, and candidates should confirm the current fee schedule and any related charges directly with AOBOS before registering. Because the application includes fellowship verification, licensure documentation, ethics attestations, and the case-log requirements described above, assembling your paperwork well ahead of any deadline is the practical lesson.

Who Hires Certified Hand Surgeons
Demand for subspecialty hand surgeons comes from several settings, and the credential helps most where privileging and referral reputation matter:
- Orthopedic groups that carry a dedicated hand or upper-extremity division and want certified subspecialists to anchor it.
- Hospitals and health systems staffing hand trauma, replantation-capable coverage, and elective upper-extremity services.
- Ambulatory surgery centers where high volumes of elective hand procedures make subspecialty expertise commercially valuable.
- Academic and teaching programs that value board-level recognition for faculty who train residents and fellows.
Specific compensation varies widely with region, practice model, and case mix, and we avoid quoting numbers we cannot verify. For a qualitative look at the earnings picture, see the Hand Surgery CAQ salary guide, and for open positions and employer expectations, our overview of Hand Surgery CAQ jobs.
Keeping the Certification Current
The certification runs on a ten-year cycle governed by Osteopathic Continuous Certification (OCC). Maintenance is not passive. For the 2025-2027 cycle, the requirements include:
- 60 CME credits, of which 15 must be Category 1-A.
- A quality-improvement attestation.
- Maintenance of professional standing.
Notably, hand surgery retains a long-form ten-year OCC exam, so the credential is not a one-time achievement. Candidates should think of the initial exam as the first of a recurring set of obligations, and keep CME documentation organized from the start rather than scrambling near a deadline.
Sequencing Your Preparation Around the Blueprint
Rather than a generic study schedule, the blueprint itself suggests how to allocate time. Weight your calendar toward the high-percentage categories, then use the lighter ones for quick, high-yield passes. A sensible arc looks like this:
Arthritis and Joint
- Build the largest content block first: thumb CMC, wrist, and finger joint pathology
- Link staging to treatment choice, since Type A questions test the best option
Nerve and Infection
- Review compression neuropathy localization and nerve injury principles
- Drill urgent-versus-conservative decisions in hand infections
Osseous, Tendon, and Tumor
- Cover fracture patterns and fixation logic, flexor and extensor tendon injuries, and common hand tumors
Microsurgery, Vascular, Amputation, Pediatrics, Soft Tissue
- Sweep the smaller categories for high-yield facts
- Finish with full timed 100-question sets in one uninterrupted two-hour block
Adjust the pacing to your own timeline and clinical load. For a more detailed plan, our Hand Surgery CAQ study guide expands on this approach, and the one-page cheat sheet is useful for last-week review. To gauge the challenge honestly, read how hard the Hand Surgery CAQ exam is and, for what the numbers suggest, the pass rate discussion. When you are ready to test yourself under realistic conditions, our Hand Surgery CAQ practice tests mirror the single-best-answer style so the format feels familiar before exam day.
Key Takeaway
Match your hours to the blueprint: the three heaviest categories (Arthritis, Nerve, Infection) should absorb the largest share of preparation, while smaller categories get efficient, targeted passes.
Frequently Asked Questions
It is the common shorthand for Subspecialty Certification in Hand Surgery, awarded through the American Osteopathic Board of Orthopedic Surgery (AOBOS). The "CAQ" label reflects the older Certificate of Added Qualifications terminology, though the official current name is Subspecialty Certification in Hand Surgery.
The exam has 100 Type A single-best-answer multiple-choice questions, delivered in a single two-hour block with no scheduled break. It is administered remotely under MonitorEDU proctoring.
A score of 500 on a 200-800 scale is the passing standard. Because the scale is scaled rather than a raw percentage, focus on broad competence across all twelve categories rather than chasing a particular number of correct answers.
Arthritis (13-15%) is the largest category, followed by Nerve (12-14%) and Infection (11-13%). Joint, Osseous, and Tendon form the next tier, with Soft Tissue the smallest at 1-3%.
No. Beyond the exam, the award requires qualifying AOBOS or AOBS primary certification, two years of active practice, appropriate privileges, 125 major hand cases within a consecutive 12-month period inside a three-year window, and at least 50% hand operative caseload.
