Hello mate,
When you refer to EMT are you talking about IHCD Ambulance Technician or a generic Emergency Medical Technician?
If you're not sure, I'll explain the differences to you.
An EMT is loose term to describe anyone without a recognised qualification who works for a private ambulance service, but is not a recognised Tech or Paramedic. It's used as a catch-all job title because there is no legal requirement to undergo any recognised training. Some EMT have as little as 4 days training which covers FPOS and FAW and nothing else. The NHS do not use EMT at all. Instead they use Emergency Care Assistants (ECA), and these are basically drivers and assitants to the clinician.
An IHCD Tech is what i've just (partially) qualified as, and is a legally protected term. The course consists of a 7 week intensive classroom course (just ask NoM how intensive), followed by 750hrs observed work (roughly 6 months) during which you have to reach certain targets and have to be observed displaying certain compentencies. The NHS no longer recruit untrained people into the Tech role (although that will probably change in the not to distant future as we are cheaper to run than Paramedics), although it is possible to do your training and hours with a private company (as I am).
The IHCD Tech course cost me approx £6500, and was a residential as well. You don't need any formal qualififcations, although a background in medicine or pre-hospital care will help you massively.
If theres anything else I can help with, just let me know mate.
