A fellowship is the period of medical training, in the United States and Canada, that a physician, dentist, or veterinarian may undertake after completing a specialty training program (residency). During this time (usually more than one year), the physician is known as a fellow. Fellows are capable of acting as an attending physician or a consultant physician in the specialist field in which they were trained, such as internal medicine or pediatrics. After completing a fellowship in the relevant sub-specialty, the physician is permitted to practice without direct supervision by other physicians in that sub-specialty, such as cardiology or oncology.

United States

In the US, the majority of fellowships are accredited by the Accreditation Council for Graduate Medical Education ("ACGME"). There are a few programs that are not accredited, yet are actually well received, given the importance of being a Board Certified Physician in a primary specialty, where a Fellowship is often more based on research productivity.[1]

ACGME Fellowships

The following are organized based on specialty required for the fellowship.

Internal Medicine or Pediatrics

General Surgery

[2] [3]

Non-ACGME Accredited Fellowships:




1 Not officially recognized as a subspecialty by the American Board of Obstetrics/Gynecology or the American College of Obstetrics/Gynecologists.








In general, ACGME accredited programs require completion of ACGME-accredited, RCPSC-accredited or CFPC- accredited residency program, however, exceptions for an ACGME-International- accredited residency programs and non-ACGME-accredited residency programs are possible.[8] International medical graduates must be ECFMG certified. Some fellowship specialties require participation in special matching programs like Specialties Matching Service® (SMS®) or SF Match.[9]

Combined fellowships

There are a number of programs offering a combined fellowship, training in two or more sub-specialties as part of a single program.
