Hand Surgery CAQ Passing Score 2026: Exactly What You Need to Pass

The 500 on a 200-800 Scale: What the Number Means

If you are researching the passing score for the Subspecialty Certification in Hand Surgery, the headline figure is simple: 500 on a 200-800 scale. This credential is administered through the American Osteopathic Board of Orthopedic Surgery (AOBOS) under the AOA, and the current official name is Subspecialty Certification in Hand Surgery. The "Hand Surgery CAQ" label persists in everyday conversation, which is why candidates still search for it that way.

A scaled score is not a raw percentage. A 500 does not mean you must answer exactly 50% of items correctly, and it does not mean you must hit any particular percentage at all. Scaled scoring exists so that results can be reported on a consistent scale across different forms of the exam. Because the official materials do not publish a raw-score conversion, any website that tells you "you need to get X questions right" is guessing. The honest framing is that you are aiming to demonstrate competence broadly enough, across all twelve content categories, that your scaled result clears 500.

For a broader look at how candidates have fared historically, see our discussion of the Hand Surgery CAQ pass rate, and for the human side of that threshold, how hard the Hand Surgery CAQ exam really is.

How 100 Questions in Two Hours Shape Your Score

Understanding the format is part of understanding the passing score, because the format determines how you convert knowledge into points. The 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 an average of roughly 72 seconds per question, with no built-in pause to reset.

Type A items present a clinical stem and ask you to select the single best response from the options. In hand surgery, "best" frequently means the most appropriate next step, the most likely diagnosis, or the preferred operative approach among several defensible choices. The difficulty is rarely obscure trivia; it is discriminating between two reasonable options and choosing the one a hand surgeon would pick in that scenario.

Because there is no scheduled break, pacing and physical readiness are part of your score strategy. Candidates who rush the first forty questions and then fade tend to give back points they already knew. Practicing in full two-hour blocks, uninterrupted, is one of the most direct ways to protect your result.

Where Your Points Come From: The 12-Category Blueprint

The official, undated blueprint organizes the exam into twelve categories and expresses each as a range rather than a fixed percentage. Those ranges tell you where points are concentrated and where a weak spot is survivable. Here is the full distribution:

Read the ranges carefully. They are not additive to exactly 100 at the midpoints, and the board uses ranges precisely because any given form of the exam can land anywhere within them. The practical implication: do not assume you will see exactly 14 Arthritis items. Plan for the possibility of a few more or a few fewer. For a deeper walk through each area, our guide to the 12 Hand Surgery CAQ content areas covers the topics inside each category.

The Three Heavy Categories: Arthritis, Nerve, and Infection

Together, Arthritis, Nerve, and Infection account for a large share of the blueprint, and the combined range is substantial. If you are trying to reach 500, these three categories are where an unforced weakness is most expensive. Notice also that these are areas where the stem often contains a long clinical picture and the answer depends on recognizing a pattern quickly.

These topic lists are illustrations of the kind of content candidates should master within each category, not a verbatim blueprint. The board's category names and percentage ranges are the official guidance; use your fellowship training and a trusted reference to fill in the detail.

Small Categories That Still Cost You Points

It is tempting to ignore the low-weight categories. Resist that. Because the passing line is a fixed 500, every missed item competes against the same threshold, and clustered gaps in smaller categories add up quickly. Soft Tissue is only 1-3%, but Amputation and Pediatrics are each 3-5%, and Vascular and Microsurgery together contribute a meaningful chunk.

Remote Proctoring Conditions and Score Protection

The exam is delivered with MonitorEDU remote proctoring, and AOA guidance references the PARADIGM practice interface. That means you take the exam from a private remote setting, subject to equipment checks and the board's allowed-materials rules, including an authorized whiteboard or tools. No claim of open-book or adaptive delivery has been verified, so plan as though neither applies.

Technical or environmental problems are an underappreciated way to lose points. A distracting room, an unreliable connection, or an unfamiliar interface can erode your pacing across a two-hour, no-break sitting. Do the equipment check early, rehearse in the same space where you will test, and use the PARADIGM practice interface if it is available to you so that navigation is second nature on exam day.

Passing Is Not the Only Gate: Eligibility Before and After the Exam

A strong score is necessary but not sufficient. Sitting for the exam and being awarded certification are two distinct steps, and each has its own requirements. You may sit for the exam after completing a one-year ACGME hand fellowship, with verification, licensure, and ethics requirements in place. The award of certification then additionally requires:

• A qualifying AOBOS/AOBS primary certification
• Two years of active practice
• Appropriate privileges
• 125 major hand cases within a consecutive 12-month period, completed within three years
• At least 50% hand operative caseload

In other words, a passing score of 500 starts the process of becoming certified; it does not finish it. If you are still assembling your case log or confirming your primary certification, read our breakdown of Hand Surgery CAQ requirements and eligibility before you pay the fee. The same logic applies to money: the initial fee is $3,000, and our Hand Surgery CAQ certification cost breakdown explains how that fits into your total outlay.

One scheduling note: the September 25, 2026 sitting has already passed. If you are planning your next attempt, check the current testing windows in our Hand Surgery CAQ exam dates guide rather than relying on a date that is no longer available.

A Blueprint-Weighted Prep Sequence

Rather than a generic schedule, sequence your review by blueprint weight and by how likely each area is to hold a hidden gap. A sensible arrangement front-loads the heavy categories, then returns to them once more near the end for consolidation. A fuller approach is laid out in our Hand Surgery CAQ study guide.

This is a template to adapt, not a prescription. If a practice block shows you are strong in Nerve and weak in Pediatrics, shift time accordingly. You can build the timed-block habit with the questions in our Hand Surgery CAQ practice test, and use our one-page cheat sheet for last-week review.

After You Pass: Ten-Year Certification and OCC

Reaching 500 and satisfying the award requirements gives you a ten-year certification maintained through Osteopathic Continuous Certification (OCC). For the 2025-2027 cycle, OCC requires 60 CME hours, including 15 Category 1-A, along with a quality-improvement attestation and professional standing. Hand surgery retains the long-form ten-year OCC exam, so the knowledge you build now has a second use a decade from now.

That durability is part of the return on the credential.
