Way before even enrolling into an EMT course.. consider my recommendation.
Go find a group of line medics.. old and young. See if they will allow you to ask them some hard facts about the profession. Then prepare a list of questions (should be at least 50-100) on the profession. Ask the usual good, bad, etc. but also ask what they would do differently, as well where they see EMS being. Ask about the side effects of being in EMS on a personal, physical level, as well as emotional levels.
Even before doing this, if you have an immediate family discuss with them the possibility of going into EMS. This action will affect them as much it will you. Not considering their thoughts as well as your relationship will be foolish. Remember, you will be working nearly every holiday, nights, weekends, and birthdays. You will be exposed to emotional distress not like you have ever seen before, again are you emotionally and physically prepared?
Check into the pay structure that you are considering. As well, look at career ladder and the ability to move upward. Sure, you are just starting out but most do not want to be at the same place 15 years from now... and that is where majority of EMS providers are at today.
Look at the educational requirements and the ability to go past that. Be sure that the school is nationally accredited from programs such as CoAEMSP, etc.
Not all programs are created equally. Get the best possible, I have yet never heard of someone complaining about getting a good education. Again, do a LOT of comparing such as clinical structures and requirements.
In regards to experience, if you can get 911 emergency experience right of the bat then go for it, if not don't waste your time with getting your EMT and awaiting for a job in shuffling patients or in a non-emergency transport system. You will become disappointed and disgruntled as well, not much to learn from there. Seriously, after you have mastered vital signs and some basics of patient assessment there is not much more you are going to obtain.
Many administrators and educators alike are finding one can be as successful or even maybe better if one has NO prior experience as an EMT. There is no bad habits to break, no dissolutions, no interference and ill advice from peers that cause complications. One will obtain experience after they become a Paramedic. Some services are now granting only partial credit to no credit as experience for being a Basic EMT. Things are changing.
