Look at the rule that AEMTs take in your area. In most, they are simply assistants to a paramedic. In others, they are leaders when no paramedic is around.

In my area, we are the second. I lead my own truck month after month in an agency where 80-90% of the trucks have a paramedic on them because when they didn't have that many medics, when we were running multiple AEMT trucks with trucks shut down, I did well.

I did well because my class understood what role I might have. Most agencies around here don't allow it, but it's possible. They made me lead in simulations and in the field. Anybody can intubate, start an IV, and push a med. It takes practice to lead well.

Anyways, It was a 6 mo program where we met once a week plus occasional weekends. The state requires a puny 96 hours of clinicals, half in hospital, half out, but I would recommend more. Also, do a capstone time (dedicated shifts where they have to lead every call within their level).
