Education, Training, & Certification

The road to becoming an internal medicine veterinarian is a long one that includes education, an internship, residency, and exams.

  • Education: All veterinarians must begin their careers by gaining admission to a veterinary school and successfully completing a Doctor of Veterinary Medicine degree. Once they achieve the basic veterinary degree and license, a candidate interested in pursuing the internal medicine specialty must make a serious educational commitment.
  • Internship: They must complete a one-year rotating internship in medicine and surgery (or demonstrate equivalent clinical experience).
  • Residency: They must complete a three to five-year residency in internal medicine (the length depends on their area of focus and the requirements of their individual program). Options for residency include subspecialties such as cardiology, large animal internal medicine, small animal internal medicine, neurology, and oncology. 
  • Certification exam: At the conclusion of the residency, a candidate must pass the general board certification exam, demonstrate that they have the appropriate credentials, and complete a specialty exam. After passing the exams the candidate is granted diplomate status in the veterinary specialty of internal medicine.
