After obtaining a medical degree, physicians are required to complete residency training in a specialty of their choice. Residency training typically lasts three to seven years and involves supervised medical practice in a hospital or clinic setting. During residency, physicians learn and practice the skills necessary to diagnose and treat patients, as well as develop their critical thinking, communication, and teamwork skills.
Some physicians also choose to pursue additional education and training beyond their medical degree and residency. This may include completing a fellowship, which is a subspecialty training program, or obtaining a master's degree in a related field such as public health, medical education, or business administration.
In summary, to become a doctor in the United States, a medical degree (MD or DO) and completion of residency training are the minimum educational requirements. Additional education and training, such as a fellowship or master's degree, may be pursued by some physicians to further specialize or enhance their qualifications.
