What Is A Thoracic Surgery?

What Is a Thoracic Surgery Credential, Exactly?

When people search "what is a Thoracic Surgery," they're often unaware that multiple credentials share similar names across different fields. On this site, Certification in Thoracic Surgery refers specifically to the board certification issued by the American Board of Thoracic Surgery (ABTS) - the formal recognition that a surgeon has completed accredited training and demonstrated the knowledge and operative judgment required to independently practice general thoracic and cardiac surgery in the United States.

It is not a single exam event. It's a two-part process: a written (Part I) examination that tests medical and surgical knowledge, followed by an oral (Part II) examination that evaluates clinical judgment through case-based discussion. This article focuses primarily on Part I, since that's the gateway every candidate must pass before moving forward. For a deeper look at the credential itself, see Thoracic Surgery Certification and What Is Thoracic Surgery Certification?.

Who Administers It: ABTS and Pearson VUE

The American Board of Thoracic Surgery sets eligibility standards, writes the exam blueprint, and issues the certificate. Delivery of the computer-based Part I exam, however, happens through Pearson Professional Testing Centers, which administer the exam at approved locations across the United States. Candidates register through ABTS but schedule their seat through the Pearson VUE system tied to ABTS.

This two-organization structure matters practically: your application, fee payment, and eligibility verification go through ABTS (abts.org), while your test-day logistics - location, identification requirements, rescheduling - go through Pearson VUE (home.pearsonvue.com/abts). Confusing the two, or assuming self-scheduling flexibility like some other computer-based exams, is a common early mistake.

Part I Exam Structure and Format

The Part I Written/Qualifying Examination is a single, high-stakes sitting built around volume and pacing rather than trick questions. Here's what candidates actually face:

• 250 multiple-choice questions, including clinical vignettes and questions that may include images (imaging studies, gross specimens, or diagrams).
• Two equal sections of 2 hours 45 minutes each, for a total testing time of 5 hours 30 minutes.
• Delivered via computer at a Pearson Professional Testing Center - no paper, no take-home component.

The sheer length is itself a factor candidates underestimate. Sustaining focus and clinical reasoning across 250 vignette-style items in one day is as much an endurance exercise as a knowledge test.

The Two Content Domains

Unlike broader surgical boards with many subspecialty sections, the ABTS Part I exam is organized around just two major domains, and understanding their internal weighting is critical to allocating study time correctly.

Because Acquired Heart Disease and Lung together make up such a large share of total exam content, candidates who under-study either one put a disproportionate amount of their score at risk. For the complete breakdown of every subtopic and how they map to the exam blueprint, see Thoracic Surgery Exam Domains 2026: Complete Guide to All 2 Content Areas.

Eligibility and Training Pathways

You cannot register for Part I without first meeting ABTS training eligibility. The board recognizes several approved routes into thoracic surgery training:

• Traditional pathway - general surgery residency followed by an accredited thoracic surgery fellowship
• Integrated six-year pathway - a combined program leading directly into thoracic surgery training
• Approved joint pathways - alternative combined training routes recognized by ABTS

Across all pathways, candidates must document sufficient operative experience - on average 125 major cases per year, with specific totals and case-type distributions varying by pathway - and must hold an unrestricted U.S. medical license. There is no shortcut around the operative logs; ABTS eligibility review checks them closely before a candidate is cleared to sit for Part I.

Fees, Dates, and Registration Mechanics

Budgeting for ABTS certification means accounting for more than a single exam fee. As of current published figures:

• $650 application fee
• $1,750 Part I written examination fee
• $2,400 total through Part I (application + written exam)
• $2,500 separate oral examination fee
• $4,900 combined total across application and both examinations

The 2026 Part I examination window is scheduled for December 7-11. Because this is a defined window rather than a rolling, on-demand testing period, candidates need to plan registration, eligibility verification, and Pearson VUE scheduling well in advance. Missing the eligibility documentation deadline can mean waiting a full cycle before the next opportunity.

Part I, Then the Oral Exam

Passing Part I does not by itself make you board-certified. ABTS requires both the written and oral examinations for initial certification. Part I qualifies you to sit for the oral exam, which evaluates clinical decision-making through case discussion rather than multiple-choice recall.

According to official 2025 results, 136 candidates passed the written exam out of 172 who sat for it - a 79.1% rate calculated directly from the board's published counts. This figure is not reported as a first-attempt-only cohort, so it reflects the overall candidate pool for that cycle, not exclusively first-time test-takers. For more context on how to interpret this number and what it implies about exam difficulty, see Thoracic Surgery Pass Rate 2026: What the Data Shows.

Who Hires Board-Certified Thoracic Surgeons

ABTS certification is generally treated as a baseline credential for practicing independently in general thoracic and cardiac surgery in the U.S. health system. Hospitals, academic medical centers, and multi-specialty surgical groups typically require or strongly prefer board certification (or active board eligibility while completing the process) for credentialing and hospital privileges. Because the certificate is non-time-limited once earned - subject to ongoing continuing certification requirements - it signals a durable, recognized standard rather than a one-time achievement.

Maintaining Certification After You Pass

Certification earned today is non-time-limited, but it is not "set and forget." ABTS requires ongoing continuing certification activity with milestones every five years. Within each five-year cycle, diplomates must complete:

• 150 AMA Category 1 CME credits total
• At least 75 of those credits specifically in cardiothoracic surgery
• Ongoing licensure and professional-standing verification
• Periodic assessment components as specified by the board

This structure rewards surgeons who stay current in both domains covered on Part I - General Thoracic and Cardiac - rather than narrowing focus entirely into one subspecialty after certification.

A Focused Way to Prepare

Because Part I splits almost evenly between General Thoracic and Cardiac, and because Lung and Acquired Heart Disease carry outsized weight within their respective domains, an effective study sequence prioritizes those high-yield areas early rather than moving chronologically through a textbook.

Generic study techniques like spaced repetition or timed blocks only help if they're applied against the right content weighting - spend equal calendar time on General Thoracic and Cardiac, but bias your hardest review sessions toward Lung and Acquired Heart Disease, since together those two subtopics likely account for the largest concentrated share of scoring opportunities.
