What do you guys mean by "credentialing"? Is that just a process of becoming certified/licensed at a state or local level after previous national registration?
After the academy and FTO time we do a skill scenario in front of the academy captains, then we will sit in front of our medical director and he will interview us to see if we are where we need to be knowledge wise. Can be anything from the packet we received in the academy, from operations to patho-phys. If we pass both of those, we are a "credentialed" provider with no restrictions. Our packet was 300-400 questions of fair game for the interview. When paramedics were being hired as medics it was about 800 questions.
Without being credentialed you are not allowed to practice without a captain or FTO on the truck. You have 9 months from the day the academy starts to pass the interview or you'll be looking for another job.
