Everyone must be eligible to take and then of course, pass, the exam of their respective discipline. Nobody is simply 'handed' registration here. Unfortunately there are people at every level who shouldn't be at ANY level.

As for oilfield EMR's, have you seen some of the people working up there? There are 18 year old bimbos who do nothing but flirt, some of which aren't even EMR's. They may have taken the course however don't want to take the exam. They run around misrepresenting themselves as EMR's, when it is common knowledge that one must be registered at their respective level in order to call themselves by that respective title.
It's all fun and games until someone loses an eye ... literally. Try putting some of these 'ladies of the patch' into a really serious situation, or even a broken arm for that matter. Then try and give one of them advice on a discussed topic or a question they've asked ... all you get is attitude and "I'm almost an EMR so I know everything thank you".
As an EMT who has spent 99% of my EMS time in emerg (a.k.a. real EMS) and the other 1% in the patch, it scares me to see what's up there. Granted, there are many true professionals in every area. The rules for 'up north' however are much too lax, and unfortunately many people who go to work (party) up there, give those of us who are simply there for the work and money a bad rap we have to dispose of.
