ExploreAbout this exam
The ABIM Transplant Hepatology Certification Examination is the subspecialty certifying examination for physicians who already hold ABIM certification in gastroenterology and who have completed accredited transplant hepatology fellowship training. The program is jointly developed by the American Board of Internal Medicine and the American Board of Pediatrics; the examination is administered to candidates from both boards at the same time in the same testing centers, with ABIM responsible for administration. This is an independent study resource and is not affiliated with ABIM or ABP.
Eligibility follows a sequence: gastroenterology certification at the time of application, satisfactory completion of formal training, demonstrated clinical competence and procedural skills, a valid unrestricted and unchallenged license, and a passing examination score. Training must include 12 months of full-time clinical transplant hepatology fellowship, meaningful perioperative responsibility for 20 liver transplant patients at a UNOS-approved center, and interpretation of at least 200 native and allograft liver biopsy specimens. Fellows must have the opportunity to train in liver biopsy, but performing the procedure is not required for certification.
ABIM's policy page does not publish an item count, time limit, passing score, or content blueprint, so confirm exam-day specifications through ABIM's registration materials. Prepare by combining supervised clinical experience with biopsy review and self-contained practice questions.
What you'll study
About ABIM Tx Hepatology preparation
Who is eligible to take the Transplant Hepatology Certification Examination?
Candidates must already be certified by ABIM in gastroenterology at the time of application, satisfactorily complete the formal training requirements, demonstrate clinical competence, procedural skills, and ethical behavior, hold a valid, unrestricted, and unchallenged medical license, and pass the examination. Fellowship training must be accredited by ACGME, RCPSC, or the Collège des médecins du Québec, or recognized as an Area of Focused Competency by RCPSC.
How many months of fellowship training are required?
The standard pathway requires 12 months of satisfactorily completed full-time clinical transplant hepatology fellowship training on top of the training required for gastroenterology certification. For fellows beginning in or after Academic Year 2022-23, ABIM lists a minimum of 12 training months and 12 clinical months. The 12 clinical months may be aggregated across the fellowship; they need not be consecutive.
What are the liver biopsy and transplant patient requirements?
Fellows must have the opportunity to train in liver biopsy to the level of competent, independent performance if they intend to perform it in practice; not every fellow must perform the procedure. Each fellow should interpret at least 200 native and allograft liver biopsy specimens. Training must also include meaningful perioperative patient care responsibility for 20 liver transplant patients at a UNOS-approved transplant center.
Can a short training deficit be excused?
For deficits of 35 days or less in required training time, ABIM defers to the program director and the promotions or competency committee. With program director attestation that the trainee has achieved required competence, additional training time is not required. Trainees cannot make this request to ABIM on their own behalf.
How does dual certification in gastroenterology and transplant hepatology work?
Beginning in 2019, dual certification requires at least 36 months of accredited combined training in a single institution with accredited programs in both disciplines. Of those months, 18 must be clinical gastroenterology training and 12 must be clinical transplant hepatology training. Candidates must complete all three years before the Gastroenterology Certification Examination and achieve gastroenterology certification before applying for transplant hepatology.
By when must training be completed for a given exam year?
Required subspecialty training, including vacation time, must be completed by October 31 of the year of examination. Plan backwards from that date, because incomplete training by the deadline affects admission to the examination.
What is the exam format, length, and passing score?
ABIM's transplant hepatology policy page does not publish the item count, time limit, passing score, or a detailed content blueprint. The page states only that the examination is administered to ABIM and ABP candidates at the same time in the same testing centers, with ABIM administering it. Confirm exam-day specifications through ABIM's registration materials.
What should I study first?
Start with the eligibility and training requirements, because they determine whether you can sit for the exam. Then build a clinical study plan around transplant hepatology practice and the required biopsy experience. Use self-contained questions and verify every policy number against the current ABIM source rather than memory.
What are common planning mistakes?
A frequent error is assuming the 12-month fellowship alone satisfies certification: the 20-patient perioperative care requirement and the 200-specimen biopsy interpretation requirement are separate. Another is missing the October 31 training-completion deadline. A third is expecting a training-deficit exception without program director involvement, since trainees cannot request it directly.
What is the retake policy?
ABIM's transplant hepatology policy page does not state retake rules, attempt limits, or waiting periods. Check ABIM's general certification policies and the examination registration materials for current retake and reapplication requirements.
