Q: How Does a Psychiatrist Make a Diagnosis so Quickly?
A: Training, training, and more training!
If you are curious about how a psychiatrist can make a diagnosis so quickly, the answer is simple – training! A Psychiatrist has a total of 12 years of training after high school – 4 years of college, 4 years of medical school, and 4 years of residency. Some psychiatrists complete an additional 1-3 years of fellowship training for a specialty like Child and Adolescent Psychiatry or Addiction Psychiatry.
This grid compares the training of different medical professionals who treat mental health issues. Since some standards vary from state to state and since there is some variation in the training, the graph below tries to illustrate the graduate education, period of time training under supervision, total patient care hours for all types of patients, and actual clinical experience in treating psychiatric patients required for licensure.

As shown above, there is significant disparity in training and supervised experience among those who treat patients with psychiatric illnesses – from psychiatric physicians and NP/PAs to non-psychiatric physicians and NP/PAs. Psychiatrists are required to have years of training and supervised practice in order to receive a medical license. In addition, psychiatrists are trained in general medicine prior to their specialty training. Traditionally, the training for NPs and PAs has been primarily medical in nature, although there are programs that provide additional training and certification in psychiatry.
