Essential Information. Doctors are licensed medical practitioners who have undergone 11-15 years of training to gain a license. This usually includes four years of undergraduate education followed by four years of medical school, divided into two years of classroom training in medicine and two years of clinical training.
To become licensed as a specialist, these new doctors still have many more years of study to go, depending on their chosen specialty. For example, to be a general internist, a doctor may study for three more years. To be a neurologist may require six or seven more years.
