One advantage of a national SOP
is that there is a standardization of EMS providers of four levels. The four levels of EMS providers described in the NEMSSOP include the emergency medical responder (formerly the certified first responder), the emergency medical technician (formerly the emergency medical technician-basic), the advanced emergency medical technician (formerly the advanced emergency medical technician-intermediate), and the Paramedic (formerly the emergency medical technician-Paramedic).
