The first country to establish a system of medical licensing was the United Kingdom in 1858.

The purpose of the first medical licensing laws was to protect the public from unqualified practitioners, to ensure that physicians had the necessary skills and knowledge, and to regulate the practice of medicine.

The two main types of medical licenses in the United States are MD (Doctor of Medicine) and DO (Doctor of Osteopathic Medicine).

The requirements for obtaining a medical license in the United States are a bachelor's degree, four years of medical school, and a residency.

The purpose of the Federation of State Medical Boards (FSMB) is to promote uniformity in medical licensing requirements, to develop and administer national medical licensing exams, and to provide continuing medical education for physicians.

The name of the national medical licensing exam in the United States is the United States Medical Licensing Examination (USMLE).

There are three steps in the USMLE.

The purpose of the USMLE is to assess a medical student's knowledge and skills, to determine if a medical student is ready to practice medicine, and to grant a medical license.

The passing score for the USMLE is 75%.

A medical student can take the USMLE up to three times.

If a medical student fails the USMLE three times, they can no longer practice medicine, they must retake the USMLE, and they must complete a remediation program.

The name of the organization that accredits medical schools in the United States is the Accreditation Council for Graduate Medical Education (ACGME).

The purpose of the ACGME is to ensure that medical schools are providing a high-quality education, to develop and implement standards for medical education, and to accredit medical residency programs.

There are approximately 200 medical schools in the United States.

Approximately 20,000 medical students graduate from medical school each year in the United States.
