Apprenticeship
Apprenticeship with a length of 3 or 4 years are the most common ones. The certificate awarded after successfully completing a 3 or 4-year apprenticeship is called "Certificat Fédérale de Capacité" (), "Eidgenössisches Fähigkeitszeugnis" (EFZ) or "Attestato federale di capacità" (AFC).
Internship (medicine)
A medical internship typically lasts one year (a loose term) and usually begins on July 1. Internships come in two variations: transitional and specialty track. After a physician has completed an internship and Step 3 of the USMLE or Level 3 of the COMLEX-USA, they can practice as a general practitioner. However, the majority of physicians complete a specialty track medical residency over two to seven years, depending on the specialty. The Accreditation Council for Graduate Medical Education (ACGME) officially dropped the term "intern" in 1975, instead referring to individuals in their first year of graduate medical education as "residents."
