I've been a patroller for 6 seasons now and I am presently in the process of getting certified as an EMT. I can say that the OEC training, on-hill training, and the actual experience you get is every bit on par with the training for EMS services (if not better). I've been cruising with ease through the EMT training and it's due to my experience and training as a Patroller.
I've talked with the instructors a bunch-related stories of on-hill first aid and rescue, our experiences and the nature of patients are very similar.
Patrol is the best gig on a Ski Hill. It's important, it's fulfilling, and it can be a lot of fun.
Just try an enjoy the OEC training, the honest truth is, OEC instructors are invested in making new patrollers, not screwing people out of becoming Patrollers. Put in an Honest effort, be of good cheer and you'll pass.
You may run into a different attitude if you ever consider trying to become a senior or certified-but at the basic OEC level, encouragement, assistance and success are at a premium.
Good luck, and welcome to the club
