Vascular Surgery Requirements 2026: Eligibility, Prerequisites & How to Qualify

What This Credential Actually Is

Primary Certification in Vascular Surgery, as covered here, is issued through the American Osteopathic Board of Surgery (AOBS), with certification approved through the American Osteopathic Association (AOA). Current issuer pages label the selected primary credential General Vascular Surgery. Because several unrelated credentials in medicine share similar names, it is worth being precise: everything below describes the AOBS pathway, its written and oral components, and its own training prerequisites. It does not describe any other board's eligibility rules, fees or exam formats.

If you are still orienting yourself to the credential itself, our explainers on what Vascular Surgery certification is and the certification overview cover the basics. This article focuses narrowly on one question: what must be true of you before AOBS lets you sit for each part of the exam?

The Training Pathway: Five Years Plus Two

The AOBS General Vascular Surgery written-exam page states the core training requirement plainly: five years of AOA-approved General Surgery training followed by two years of AOA-approved General Vascular Surgery training. That is the headline prerequisite for the specialty, and it is the one most candidates plan their careers around.

Applicants who have not yet finished

You do not have to be fully finished with training on the day you apply. Applicants within 90 days of completing their program must submit a letter from the program director supporting the application. This matters for residents and fellows finishing in late spring or early summer, because the application and approval clock runs before graduation.

A scope conflict you should know about

The AOBS common Board Policies are written more broadly than the specialty page. They accept COCA graduates with AOA/ACGME training and LCME graduates with ACGME training. However, those general policies do not establish a specific integrated vascular alternative to the specialty page's "five plus two" training language. In practice, that means you should not assume that an alternate or integrated training format automatically satisfies the specialty requirement just because the general policy accepts the degree type. If your training path is anything other than the standard sequence, confirm your status with AOBS in writing before you pay any fees or schedule travel.

Licensure and Conduct Requirements

Beyond training, the common AOBS Board Policies require two baseline conditions:

• An unrestricted, active U.S. medical license. A restricted or inactive license is a problem for eligibility, not just a paperwork nuisance.
• Compliance with AOA ethical standards.

These are not one-time checks. Annual unrestricted-license verification and ethics compliance continue as part of ongoing certification maintenance, covered later in this article. If you have any licensure action, pending board matter or lapse in your history, resolve it or at least disclose it early rather than discovering a problem near the application deadline.

The RPVI Prerequisite

The specialty written page lists RPVI examination success among the requirements, alongside the application and fees. RPVI is a vascular interpretation credential, and passing it is a distinct step you complete on your own timeline. It is separate from the AOBS written and oral exams and has its own registration process.

The practical implication: do not leave RPVI until the final months. Because documents must be approved at least 14 days before testing, a pending or failed RPVI result discovered late can push your whole sequence back by an administration. Diagnostic interpretation knowledge from RPVI preparation also overlaps usefully with the exam's Diagnostics (incl. Doppler), Pharmacology, Dialysis content area, so the preparation is not wasted effort. For a sense of how that content area fits into the blueprint, see our complete guide to all 26 content areas.

Application Timing, Documents and Fees

Document approval deadline

Your application documents must be approved at least 14 days before testing. Note the wording: approved, not merely submitted. Submit early enough that AOBS has time to review, request corrections and approve.

Fee structure

For the usual two-exam route, base AOBS examination fees are:

No separate member versus nonmember tier is published. Travel, review products and any applicable late charges are additional costs, so the true out-of-pocket figure is higher than $3,000. Our certification cost breakdown walks through the full budgeting picture.

Cancellations, transfers and rescoring

• Cancellation: The written and oral pages describe a $500 deduction for timely cancellation and no refund after that point.
• Oral boundary wording: The oral page uses both "30 days or more" and "within 30 days" phrasing at the exact cutoff, so do not rely on a same-day-as-the-deadline cancellation. Cancel comfortably before the 30-day mark.
• Transfer: One board-approved transfer is available for extenuating circumstances, moving you to the next administration.
• Rescore/audit: A $200 rescore or audit may be requested within one month of results. It does not provide access to individual items and does not reconsider the passing cutoff.

What You Qualify to Sit: The Written Exam

Meeting the prerequisites earns you access to the written examination, which AOBS describes as 200 multiple-choice questions in 4 hours 30 minutes. The passing standard is a scaled score of 500 on a 200-800 scale, which is not a percent-correct mark. The split between scored and unscored questions is not specified, so avoid assuming that every item counts. For a closer look at the score itself, see our guide to the passing score.

Delivery requirements

The written exam is remotely proctored through the MonitorEDU Secure Browser. Your testing environment must include:

• A private room
• A computer and a mobile device
• A government photo ID that matches your AOA candidate ID

AOA recommends a personal computer with administrator access, since locked-down work machines can block the secure browser. Online lab values, a scratch pad and a calculator are supplied within the exam. Whether the initial written examination is open-book or adaptive has not been verified, so do not plan around either assumption.

What the blueprint rewards

The published content outline lists 26 headings with percentage ranges. These are ranges, not fixed weights, and some headings overlap. The largest ranges are:

Because eligibility is only the first hurdle, it helps to know how demanding the exam is once you are in. Our difficulty guide and pass rate analysis cover that side.

The Oral Clinical-Case Examination

The oral stage requires program completion and board approval. It is a clinical-case examination assessing diagnostic interpretation, management and judgment. Its passing standard is criterion referenced, and the reviewed oral page publishes no numeric cutoff, total case count or duration, so do not trust anyone who quotes you specifics about those.

Format and logistics

• The oral page retains a dated September 30, 2026 notice for in-person testing in New Orleans and states explicitly that there are no virtual oral examinations in 2026.
• The AOBS Rules of Conduct for the In-Person Oral Exam require government-issued photo ID and prohibit notes and books in examination and sequestered areas, and electronic devices in the examination room.

The practical eligibility angle: because the oral exam is in person and tied to program completion, your fellowship end date, license status and travel planning all feed into when you can realistically sit. Test the logistics early.

The ABS VSQE Alternate Route

A dated AOA announcement from April 29, 2026 describes a newer route: AOBS now accepts a pass on the ABS Written Vascular Surgery Qualifying Exam (VSQE) as meeting the written requirement for AOBS oral application. Three limits keep this in perspective:

• The remaining AOBS requirements still apply.
• This route does not replace the AOBS written blueprint.
• It does not change the credential described in this article; it is an alternate way to satisfy one eligibility element.

Eligibility Windows and Retake Rules

Eligibility is not permanent. Ordinary board eligibility ends December 31 of the sixth year following training. That is a firm outer limit, so a candidate who delays the exam for fellowship extensions, relocation or family reasons should calendar the cutoff explicitly.

Failure and retesting

• After an initial or second exam failure, retesting must occur within two years to keep the file active.
• After a third written and/or oral failure, the oral page requires documented board-review-course remediation before further attempts.

Scheduling caveat

Published sources disagree slightly on the written exam month. The generic timeline mentions annual May testing, while the written page says April, and the board homepage lists the next Spring Qualifying Examination on May 1-3, 2027 and the oral examination on October 20, 2027 in Orlando. Administration-specific notices should govern your plans. Our exam dates and scheduling guide tracks these windows.

Staying Qualified After Certification

Qualifying is one milestone; remaining certified is another. The exact timeline describes active certification for one year after issue, conditional on Osteopathic Continuous Certification (OCC), rather than an unconditional ten-year term. Ongoing requirements include:

• Component 1: Annual unrestricted-license verification and ethics compliance.
• Component 2 (CME): 60 credits per three-year cycle for time-limited diplomates and non-time-limited diplomates voluntarily participating in OCC; 120 for non-time-limited diplomates outside OCC. No separate AOBS Category 1 or specialty-specific minimum is listed. Newly certified physicians' mid-cycle requirements are prorated.
• Component 3: An annual 15-question open-book longitudinal assessment, 12 of 15 (80%) to pass, with a $225 registration fee in 2026 covering two attempts, delivered through the AOA LMS.
• Component 4: At least one QI/QA attestation every three years.

The maintenance assessment is separate from initial certification, and annual participation begins in the certificate-expiration year. Certificates issued after 2018 omit printed expiration dates. Some component pages retain older wording, such as legacy ten-year-cycle language, which does not override the current timeline.
