The way things worked, when I was trained as an EMT by my paramedic partner, I was "drilled" on all the basics by him (and our other, more experienced EMT partner) and then I was immersed in learning everything I could to act as HIS assistant for advanced calls. Which meant I got to practice communication, learned all the drugs in the box, how to set them up; essentially handling everything the paramedic does up to, but not including the point of administering invasive therapy.
Perhaps that is an important qualification: an EMT is an entry point into a mentored system where, on the job, he/she is learning all of the things that are done to assist the paramedic, which should include learning most everything the paramedic knows on the preparation side.
