lets go question by questions
I am currently 17 and plan on taking an EMT B class in march when im 18 at ictc.
Some states will allow you to start the class before you turn 18; some will even let you become certified before you turn 18. all depends on your individual state
Do i need CPR certification before enrolling?
depends on the course. most places will include a CPR course (or at least a skills verification) during the class; however, I would recommend taking an AHA BLS provider course before you start. it's less than $100, and it gives you a little bit of a heads up on what is going to be covered. Again, just my personal opinion. But even better would be to ask the EMT program you will be attending if they require CPR before the course starts.
Where should i get my CPR certification?
any AHA instructor can run one; just google CPR class in (insert your town/county/state here).
ehhh, it's far from impossible, but if you do all the reading, study, pay attention in class, do the homework, and ask questions when things are unclear, you should have no problems. That being said, if you don't put the time in, the chances of you having issues increases significantly.
Will i be able to get a paid job as an EMT at 18?
maybe. depends on where you live, what you want to do, and if you can convince someone to hire you.
And will the salary be enough?
enough to do what? live a luxurious life? absolutely not. afford a 7 bedroom house? probably not.
you're 18 years old; either live at home, or find some roommates. your first job will probably pay your poorly. most first jobs out of HS tend to suck. Do it for a year and see what your financial situation is.
my first EMT job was $10.25 an hour. a week later i was offered a position making $11.25/hr. when I wanted to find a full time position, they offered me $9 an hour. Several years later, I was offered a part time position making $12/hr. a year later, I was making $15 an hour. When I left that job, I was making $20/hr, and I left for a union EMS job making $18 an hour, and 5 years later, I left, making $22 an hour, and moved south, and was making $15 an hour. And then got hired part time at another agency making $12.50 an hour.
Salaries go up and down depending on your employer, your experience level, the job you will be done, the schedule, and how much they want to pay you, but when you are break into a new field, especially in EMS, don't expect to get rich overnight.
