After medical school, a doctor who wants to be a psychiatrist completes a residency that the Accreditation Council for Graduate Medical Education sets at 48 months, usually called PGY-1 through PGY-4. The first year includes months of general medicine and neurology before psychiatry takes over. After residency, most psychiatrists take a board exam to become certified, and some add a one or two year fellowship in a subspecialty.
Key takeaways
- Psychiatry residency is four years long, set at 48 months by the ACGME.
- The first year mixes internal medicine, neurology, and psychiatry, so a new psychiatrist is also trained as a physician first.
- Residents move from supervised inpatient work toward outpatient care, psychotherapy, and more independence over the four years.
- Board certification through the ABPN comes after residency, and subspecialty fellowships add one to two more years.
The path in one paragraph
A psychiatrist is a physician first. The path runs through four years of college, four years of medical school, and then residency, which is paid, supervised training inside a hospital or health system. For psychiatry, the Accreditation Council for Graduate Medical Education (ACGME) requires that residency to be 48 months long. People count those years as PGY-1 through PGY-4, where PGY stands for postgraduate year. Only after all of that does someone practice independently, and most go on to take a board exam to be certified.
The thing that surprises people is how much of the early training isn't psychiatry at all. That's on purpose. Psychiatric patients have bodies, take other medications, and develop medical illnesses that can look like psychiatric ones. A psychiatrist who can't recognize a thyroid problem or a drug interaction isn't fully trained, so the field builds general medicine into the foundation.
PGY-1: still a doctor first
The first year of psychiatry residency, the intern year, deliberately looks a lot like internal medicine. ACGME rules require a stretch of months in general medical care and in neurology, alongside the first psychiatry rotations. An intern might spend the morning managing blood pressure and diabetes on a medicine ward and the afternoon learning to assess a first psychotic episode.
This is where the habit of ruling out medical causes gets built. By the end of the year, a resident has admitted patients, written orders, handled emergencies, and started to learn psychiatric interviewing under close supervision. They're a licensed doctor doing hospital medicine who happens to be heading toward psychiatry.
PGY-2: psychiatry takes over
The second year is when psychiatry becomes the center of gravity. Residents rotate through inpatient psychiatric units, the emergency room, consultation services that advise other medical teams, and often addiction and geriatric settings. The volume is high and the supervision is still heavy, because this is where pattern recognition is forged.
A PGY-2 sees a lot of acute illness in a short time: mania, psychosis, severe depression, withdrawal, suicidal crises. They learn to start and adjust medications, to assess risk, and to write the kind of careful note that the rest of the team and the next clinician will rely on. It's demanding work, and it's where many residents say they finally feel like psychiatrists.
PGY-3: the outpatient year
The third year usually shifts to the clinic. Residents carry their own panel of outpatients over months and sometimes years, which is the first time they see how people actually change with treatment over time. This is also the year psychotherapy training becomes central. ACGME requires residents to demonstrate competence in several forms of psychotherapy, so a PGY-3 might be learning cognitive behavioral therapy, psychodynamic therapy, and supportive therapy at once, each with its own supervisor.
Continuity is the lesson of this year. Medication management looks different when you're the one who prescribed it three months ago and you're watching what happened. The work gets quieter and, in some ways, harder.
PGY-4: independence and electives
By the fourth year, residents function with much more independence and often take on teaching and leadership roles, supervising junior residents and medical students. The schedule opens up for electives, so a senior resident can go deeper into an interest, whether that's child psychiatry, forensic work, research, addiction, or running a clinic. Many use the year to prepare for whatever comes next, including fellowship applications or job hunting.
After residency: boards and fellowships
Finishing residency makes someone eligible for board certification through the American Board of Psychiatry and Neurology (ABPN). Certification isn't legally required to practice, but it's the standard credential, and many hospitals and insurers expect it. It involves passing an exam and then keeping the certificate active through an ongoing continuing-certification process rather than a single test that lasts forever.
Some psychiatrists then add a fellowship, which is extra subspecialty training that usually runs one to two years. Common ones include child and adolescent psychiatry, consultation-liaison psychiatry (the medical-psychiatric interface), addiction psychiatry, geriatric psychiatry, forensic psychiatry, and sleep medicine. Child and adolescent psychiatry is the largest, and it's a two-year fellowship.
What's commonly misunderstood
People often think psychiatrists train mainly in talk therapy, or that they barely train in it at all. Both are wrong. Residency requires real competence in psychotherapy and in medical management, because the job is the combination. People also assume residency is shorter than it is. At four years after medical school, training a psychiatrist takes well over a decade from the start of college, which is part of why the workforce can't expand quickly to meet demand. We cover that supply problem in the psychiatrist shortage.
Common questions
How long is psychiatry residency?
Psychiatry residency is four years, which the ACGME sets at 48 months, completed after medical school. Subspecialty fellowships add one to two more years.
Do psychiatrists train in therapy or just medication?
Both. ACGME requirements include demonstrated competence in several forms of psychotherapy as well as medical and medication management. The job is the combination of the two.
Is board certification required to practice psychiatry?
No. A medical license is what's legally required. Board certification through the ABPN is the standard professional credential and is often expected by employers and insurers, but it isn't a legal requirement.
