If students have a D.O. they will need to complete at least one year of internship before their residency. If students obtained an M.D. they can usually move right into residency. They will need to complete a psychiatric residency usually lasting around four years. This will provide them with the hands on training they need to be successful in their careers under the supervision of licensed psychiatrists. If psychiatrists want to have a specialty, they usually would complete a few more years of residency or a fellowship. Once this is completed they are almost ready to practice! The last important step is to become board certified. Psychiatrists must obtain a valid license so they can practice in all states. This is a written and oral exam that must be retaken every ten years.
Now that you know the career path of a psychiatrist, good luck in your studies.
