Odds of Getting In
The odds are quite good. EMT is a demand occupation, which means there are plenty of jobs. (Thank you, baby boomers, for all of your bad lifestyle choices.) The number of EMT jobs is expected to grow by one third during this decade.
The training (about 100 hours) and testing to become a basic-level EMT are not difficult. You don't need a rocket scientist's intellect to succeed. Courses are offered frequently by colleges and employers, and take about three months to complete. Certification is usually awarded by state health departments. There is also a National Registry of EMTs.
If you want to become an intermediate or paramedic EMT, much more training is required. It can require 1,000 hours for intermediate and 1,300 for paramedic and take as long as two years to complete.
You'll be a basic EMT first. Higher-level skills can command more and better job offers. A flight EMT will require additional specialized training. It might take a while, but the high turnover rate (see Odds of Hanging On) helps to ensure an ongoing number of EMT job openings.
