Internal Medicine & Subspecialty Policies

ABIM Certification Exams

Make a selection below to learn more about one of ABIM's certification exams. ABIM diplomates may also be eligible for additional certifications through other ABMS Boards.

To become certified in internal medicine, physicians must meet specific requirements set by the American Board of Internal Medicine. This page provides an overview of eligibility criteria, required training, clinical competence standards and the certification exam process—everything needed to understand the path to certification.

The information provided on ABIM's website and in ABIM's print publication, Policies and Procedures for Certification, December 2025 (pdf), governs ABIM's decision about eligibility for certification. The December 2025 edition supersedes all previous publications. ABIM reserves the right to make changes in fees, examinations, policies and procedures at any time without advance notice. Admission to ABIM's certification process is determined by policies in force at the time of application. ABIM is a member of the American Board of Medical Specialties (ABMS).

To become certified in internal medicine, a physician must complete the requisite predoctoral medical education, meet the graduate medical education training requirements, demonstrate clinical competence in the care of patients, meet the licensure and procedural requirements, and pass the ABIM Internal Medicine Certification Examination.

Predoctoral Medical Education

Candidates who graduated from medical schools in the U.S. or Canada must have attended a school that was accredited at the date of graduation by the Liaison Committee on Medical Education (LCME), the Committee for Accreditation of Canadian Medical Schools or the American Osteopathic Association.

Graduates of international medical schools must have one of the following: (1) a standard certificate from the Educational Commission for Foreign Medical Graduates without expired examination dates or (2) comparable credentials from the Medical Council of Canada.

Graduate Medical Education (GME)

To be admitted to the ABIM Internal Medicine Certification Examination, physicians must have satisfactorily completed 36 calendar months, including vacation time, of U.S. or Canadian graduate medical education accredited by the Accreditation Council for Graduate Medical Education (ACGME), the Royal College of Physicians and Surgeons of Canada, or the Collège des médecins du Québec by August 31 of the year of examination. Residency or research experience occurring before completion of the requirements for the MD or DO degree cannot be credited toward the requirements for certification. The 36 months of accredited internal medicine residency training must be reported in 12-month intervals according to the Clinical Competence Requirement training tables (see below). No credit is granted for unsatisfactory training that requires repetition of a training year at the same level or for administrative work as a chief medical resident. In addition, training as a subspecialty fellow cannot be credited toward fulfilling the internal medicine training requirements.

The total months of training required, including specific clinical months, and requisite procedures are outlined below:

  • Procedures are essential to internal medicine training; to be eligible for certification, all residents must perform procedures during training.
  • Not all residents need to perform all procedures.
  • Program directors must attest to general competence in procedures at the end of training
  • At the completion of training, residents must have demonstrated effective consent discussions, standard or universal precautions, establishment of a sterile field, and application of local anesthetic as applicable to most procedures a resident may perform.
  • Residents must have the opportunity to develop competence in procedures which will further their development as fellows in their chosen subspecialty, or as independent practitioners in their intended fields if entering practice after residency.
*For deficits of 35 days or less in required training time, ABIM will defer to the judgment of the program director and promotions or competency committee in determining the need for additional training. With program director attestation to ABIM that the trainee has achieved required competence, additional training time will not be required. Trainees cannot make a request to ABIM on their own behalf.

Content of Training

The 36 calendar months of full-time internal medicine residency education:

  1. Must include at least 30 months of training in general internal medicine, subspecialty internal medicine and emergency medicine. Up to four of the 30 months may include training in areas related to primary care, such as neurology, dermatology, office gynecology or office orthopedics.
  2. May include up to three months of other electives approved by the internal medicine program director.
  3. Include up to three months of leave for vacation time. (see “Leave of Absence and Vacation Policy”)

    For deficits of 35 days or less in required training time, ABIM will defer to the judgment of the program director and promotions or competency committee in determining the need for additional training. With program director attestation to ABIM that the trainee has achieved required competence, additional training time will not be required. Trainees cannot make a request to ABIM on their own behalf.

In addition, the following requirements for direct patient responsibility must be met:

  1. At least 24 months of the 36 months of residency education must occur in settings where the resident personally provides or supervises less-experienced residents who provide direct care to patients in inpatient or ambulatory settings.
  2. At least six months of direct patient responsibility on internal medicine rotations must occur during the R-1 year.

Procedures Required for Internal Medicine

The exposure to the performance of, and the opportunity to develop competence in, invasive procedures by residents is essential for internal medicine residents’ preparation for their subsequent subspecialty fellowship or chosen career path.

As of the 2019-20 academic year, residents must meet the requirements outlined in the table above to be admitted to the Internal Medicine Certification Examination. Internal medicine graduates will likely perform some invasive procedures in the course of their future training or practice; however, the specific procedures will vary based on subsequent subspecialty or general career path pursued. The performance of all invasive procedures requires the ability to facilitate an effective discussion with patients regarding risk and benefit of the procedure before obtaining consent, a critical task that all internists must effectively perform. Internists who perform any invasive procedures must be able to initiate a standardized preparation beforehand, including handwashing, donning of sterile gloves, preparing the procedural field and applying some form of anesthetic. Procedural competence need not be determined solely by a minimum number of successfully completed procedures, but may be customized as appropriate through simulation, direct observation and other criteria determined by the program director and clinical competency committee.

ABIM requires documentation that candidates for certification in internal medicine are competent in:

  1. Patient care and procedural skills
  2. Medical knowledge
  3. Practice-based learning and improvement
  4. Interpersonal and communication skills
  5. Professionalism
  6. Systems-based practice

Through its tracking process, FasTrack®, ABIM requires verification of residents' clinical competence to come from a program director who is certified by ABIM in the discipline for which they are program director (other ABMS Member Board or Canadian certification is acceptable, if applicable).

As outlined in the Program Director Ratings of Clinical Competence table below, all residents must receive satisfactory ratings in overall clinical competence in each year of training. In addition, residents must receive satisfactory ratings in each of the six ACGME/ABMS Competencies during the final year of required training. It is the resident's responsibility to arrange for any additional training needed to achieve a satisfactory rating in each of the six ACGME/ABMS Competencies and overall clinical competence.

Program Director Ratings of Clinical Competence

Six ACGME/ABMS Competencies*

The resident/fellow must demonstrate satisfactory development of the knowledge, skills and attitudes/behaviors needed to advance in training. The trainee must also demonstrate a learning trajectory that anticipates the achievement of competency for unsupervised practice, which includes the delivery of safe, effective, patient-centered, timely, efficient and equitable care.
