EFR doesn't offer the health care version of CPR, but it is still within ILCOR standards for lay people. The major problem with it is it has limited itself to lay people only.
As for teaching for AHA, the main problem with that is you cannot be an "independent". You must work with a training center and offer all courses through that training center. At least with ARC and EFR you can work independently, through ARC as an Authorized Provider.
I wasn't saying it did not follow ILCOR standards, actually I was saying it did follow their standards because they come from ILCOR and AHA.
In addition, you can be your own training center, and in essence then teach for yourself. Its not difficult, lot of people in the fire departments offer those classes and they are training centers. So that is only a matter of applications. In addition, many larger training centers, will merely host your certifications and allow you to set your own pay rate and everything and just require the 2 dollars per card and the completed rosters, eval sheets and skills checkoffs sheets...this is how I currently work as an instructor trainer through AHA. And I am working through a training center which is run by a person in the FD. Nothing major...
