Re TSandM and her response -- she is incorrect -- I was permitted to use her ACLS card as proof of current CPR/EFR.
BUT, and this may be why she responded as she did, even though she has all that and has been doing ER work for 20+ years, including teaching residents and PAs, she can not get her EFR Instructor Rating without taking the EFR Instructor course.
Which is why I gave up teaching CPR, and First Aid for any agency a long time ago. Even though I am a professional in the field and at the time was PERFORMING CPR on a nearly weekly basis, the hassle of the instructor and agency specific renewal requirements made it almost time prohibitive to continue. It wasn't the actual class time that was the problem, it was finding a compatible time and place so I could attend. If you teach enough classes it is worth it, but for the person volunteering their time to teach these skills, it is hard to justify. I still teach, but generally to the Boy Scouts, where they don't get a certificate (only a merit badge FWIW), but do get very valuable life skills.
