Medical Education Progression

People in the US begin as a medical student who is in medical school and is not yet a doctor. Other countries have similar, but different terms for medical professionals.

After medical school they become an intern, then resident. Interns are people in their first year of residency. All interns are residents, but not all residents are interns.

Residents have officially completed their medical degree and are medical doctors, but do not have a specialty or license. A resident still needs to work under an attending doctor. Residency is where they learn to become a specialist, such as a surgeon. Residents typically work 3-5 years in specialty training. They do not get their medical license to practice until after residency.


Everyone needs a license to practice as a regular doctor aka attending. Attendings are people who can independently practice in a particular area without anyone supervising them. They can be either a D.O. (Osteopath) or a M.D (Allopath) and both pass the same board exams.

In order to become a specialist they need to be an attending doctor first. Fellowship is sub-specialty training after residency. They are specializing even further, into things, such as cardiac surgeons must complete four years of college, four years of medical school, a 5-year general surgery residency and a 2-3 year specialized cardio or cardiothoracic fellowship.
