What should be taught
If I just stick to EASAland, which is where I work, the regs are fairly broad: a table of topics and a reference to NOTECHS behavioural markers. They also say that CRM should be tailored to company needs and should be integrated into all phases of training.
In fact, the regulations are the product of muddled thinking.
The content of a training course does not need to be dictated by a set of regulations. A facilitator (or a training designed on behalf of the facilitator) should be able to identify what workplace performance needs to be developed, identify a set of skills and associated underpinning knowledge, define learning goals, develop the training intervention, deliver and - in a really perfect world - measure the effectiveness of the training. At that point, you go back to the regs and cross-reference. Now, if you cannot do that (or don't have access to that support) then, I am afraid, the job is not being done properly.
I don't know why there is such a lack of response given that the request for resources keeps coming up. Perhaps people don't document their training sessions with even the most basic lesson plan? Maybe people don't develop case studies? Maybe they really are just shy? Most of the stuff I put up was developed years ago when I was just starting out in this business. It's not earth-shattering and I couldn't give a tinkers cuss if someone wants to offer a critique. I do have very different views about CRM training now and wouldn't develop a course the same way today. But that is a whole different issue.
