The EMSA program is affiliated with Redlands Community College in El Reno, OK. Currently, the Eastern division in Tulsa is also sending students to Tulsa Community College as they just started a program as well. To be accepted into the program requires 6 months experience as an EMT at EMSA. You'll also be graded based on resume, previous education, entrance exam, interview, and supervisor reviews. That being said, though it was once a fairly competitive process, we're running short on quality EMTs and the current applicants aren't a stellar looking bunch. Getting in would be very easy right now.
The teacher for the program in Tulsa is very talented and, in my opinion, the absolute best option for paramedic programs in the region. He teaches well beyond EMSA standards and is devoted to developing competent paramedics. Can't speak for the City's teacher. Unless it changes, while in the program you are in school 3 days a week from 8a-5p and you work 2 12-hour street shift as an EMT on the weekends. Once the school portion ends, you are taken off the streets and solely do your clinicals. You are paid for all hours you are in class. The only paramedic students who have specific shifts blocked off for them are those being put through school by AMR. You could possibly go to school on your own while working full time but it will suck, and even though EMTs fly through the ranks in seniority, there's no guarantee you'll get a shift that works with school.
The price for this is high. You have to sign a contract to work for AMR for three years after clearing as a paramedic. And working at EMSA is not particularly fun right now. Tulsa is leaps and bounds better than OKC but even up here we're getting weary of the high call volume with no fixes being attempted by AMR. Not that they can afford to do anything to fix it anyway seeing as they seriously underbid the contract and the outfit is not making money. Morale is at an all-time low to say the least.
My suggestion: Don't do it. AMR is awful to work for. The quality of the education is fine but the working conditions are not. There are plenty of places in Oklahoma that pay for their EMTs to go through paramedic school. There is a shortage of paramedics here after all. Cherokee nation EMS has their own program now and they're great to work for. Creek County EMS gives scholarships for school. And these are just the ones I know off the top of my head. EMSA advertises better but there is no shortage of opportunities to get school paid for. Be smart about it.
