It functions within the Office of Emergency Medical Services of the National Highway Traffic Safety Administration of the U.S. Department of Transportation. Every two years experts in the various disciplines within EMS/Paramedicine are appointed by the Secretary of the Department of Transportation. Virtually every stakeholder group of EMS/Paramedicine is represented by the appointees, who also make up a geographic mixture of the country.
