An EMT-Paramedic training program is required to attain the highest level of emergency medical technician training. Such programs generally require a high school diploma for entry. A variety of training programs are available through community colleges, hospitals and fire departments.
The National Registry of Emergency Medical Technicians (NREMT) provides national certification of EMTs and paramedics at four levels: EMR, EMT, Advanced EMT, and Paramedic. Some states, however, have their own certification programs and use similar titles.
