What Is A Hand Surgery CAQ?

What a Hand Surgery CAQ Actually Is

When surgeons ask "what is a Hand Surgery CAQ?", they are usually asking two things at once: what the letters stand for, and what the credential proves. In this context, the label refers to the Subspecialty Certification in Hand Surgery, offered through the American Osteopathic Board of Orthopedic Surgery (AOBOS) under the American Osteopathic Association (AOA). The official name today is Subspecialty Certification in Hand Surgery, but the "Hand Surgery CAQ" shorthand persists in conversation, job postings and credentialing paperwork, so this site keeps it as the working label.

The credential documents that an orthopedic surgeon has completed focused hand fellowship training, performed a meaningful volume of hand surgery in practice, and passed a standardized examination covering the breadth of the discipline. It is not a primary board certification. It sits on top of one, which is why the eligibility pathway (covered below) starts with qualifying AOBOS or AOBS primary certification.

If you want a plain-language walkthrough of the terminology itself, our pages on what Hand Surgery CAQ stands for and the Hand Surgery CAQ meaning cover the vocabulary. This article focuses on how the credential works in practice.

Who Issues It and How It Is Delivered

AOBOS administers the certification, and the examination is delivered through MonitorEDU remote proctoring. AOA guidance also references the PARADIGM practice interface, which candidates can use to become comfortable with the testing environment before the real sitting.

Remote delivery has practical consequences you should plan for:

• Private setting required. You test in a private remote location, not a crowded clinic workroom or a shared office.
• Equipment checks apply. Run the technical verification well before exam day rather than discovering a webcam or bandwidth problem at check-in.
• Authorized tools only. A whiteboard and approved tools are permitted; the materials you may use are defined by the proctoring rules. No open-book format or adaptive testing has been verified for this exam.

The Path to Eligibility and Award

There are two distinct gates: sitting for the exam and being awarded the certificate. Many candidates conflate them, so it helps to separate them clearly.

Gate One: Eligibility to Sit

A candidate may sit after completing a one-year ACGME-accredited hand fellowship, with fellowship verification, along with licensure and ethics requirements. The exam is therefore attainable close to the end of training, before practice-based requirements are complete.

Gate Two: Award of Certification

Passing the exam is necessary but not sufficient. The award additionally requires:

• Qualifying AOBOS or AOBS primary certification
• Two years of active practice
• Appropriate hospital or facility privileges
• 125 major hand cases logged within a consecutive 12-month period, within three years
• At least 50% hand operative caseload

The case-volume and caseload-share requirements are what separate this credential from a pure test of knowledge. A surgeon who passes the exam but whose practice is predominantly general orthopedics may not meet the award criteria. For a fuller breakdown of each prerequisite, see our guide to Hand Surgery CAQ requirements and eligibility.

What the Exam Looks Like

The Hand Surgery CAQ exam consists of 100 Type A single-best-answer multiple-choice questions delivered in one two-hour block with no scheduled break. That works out to roughly 72 seconds per question, which is tight for clinically dense stems that describe a patient, an imaging finding or an operative decision and then ask for the single best next step or diagnosis.

Type A format has several implications:

• Every distractor is typically plausible, so the task is ranking options, not recognizing a single obviously correct answer.
• Questions reward integrated reasoning: anatomy, indications, technique selection and complication management often appear in the same item.
• Because there is no scheduled break, stamina and pacing matter as much as raw knowledge.

The passing score is 500 on a 200-800 scale. Scaled scoring means 500 is not simply "50% correct"; it is a standard-set threshold. For a closer look at how scaled scores work, read our explainer on the Hand Surgery CAQ passing score.

How the 12-Category Blueprint Shapes Your Preparation

The official blueprint is organized into 12 content categories, published as ranges rather than fixed percentages, and it is undated. The ranges tell you where the exam spends its questions, which should drive where you spend your hours.

Three observations stand out. First, the top three categories (Arthritis, Nerve and Infection) together account for a large share of the exam, so shortcomings there are costly. Second, Joint, Osseous and Tendon form a solid middle tier that should not be neglected. Third, the small categories (Amputation, Pediatrics, Soft Tissue) are individually minor but collectively not negligible, and they are often where a strong clinician loses easy points through lack of recent exposure.

Our full walkthrough of every category is in the Hand Surgery CAQ exam domains guide.

Topics Worth Mastering First

The mid-weight categories reward the same kind of integrated thinking. Joint questions often turn on instability patterns and ligament injuries; Osseous questions on fracture pattern, fixation choice and malunion or nonunion management; Tendon questions on repair zones, rehabilitation protocols and secondary reconstruction. For a detailed content outline of these areas, see the Hand Surgery CAQ cheat sheet.

Sequencing Your Review by Domain

This is the one place where scheduling matters, and it should follow the blueprint rather than a generic template. A reasonable arc for a candidate with several months of lead time:

Fees and Registration Mechanics

The initial fee is $3,000. That figure covers the certification process at the initial stage; additional costs such as travel are largely moot given remote delivery, but fellowship verification, licensure documentation and preparation materials are separate considerations. Because a sitting date has already passed (the September 25, 2026 sitting is behind us), candidates planning ahead should confirm current scheduling directly with AOBOS rather than relying on any single date.

Staying Certified: The Ten-Year Cycle

The certification runs on a ten-year cycle with Osteopathic Continuous Certification (OCC). For the 2025-2027 cycle, requirements include:

• 60 CME credits, of which 15 must be Category 1-A
• A quality-improvement attestation
• Demonstration of professional standing

Notably, hand surgery retains the long-form ten-year OCC exam. That means earning the credential is not the end of formal assessment: you should expect to prepare for a comprehensive recertification exam at the decade mark, which is one reason building durable knowledge during initial preparation pays off later.

Who Values the Credential

The certification carries weight with the employers and structures that depend on documented subspecialty competence:

• Hospital credentialing committees that grant hand surgery privileges and look for verified training and certification.
• Orthopedic and multispecialty groups building or expanding hand service lines, where a subspecialty-certified surgeon can anchor referral pathways.
• Trauma and emergency-oriented centers that need coverage for acute hand injuries, infections and replantation-adjacent cases.
• Academic and training programs that expect faculty to hold the relevant subspecialty credential.

Whether the credential translates into a measurable earnings advantage depends heavily on your market and practice setting, so we deliberately avoid quoting figures here.
