We are doing a security audit/pen test for a client right now. As the security guy I am heavily engaged in the process. At a later point, I am going to have to hold a training session for the employees on security. Is there a standard or any guidelines for this type of stuff? I am aware of some pretty cool standards for the technical side but I've never really heard of anything like that on educating users. I have a rough idea of what it should consist of but I really want to do a good job so if you guys know of a framework I can follow when piecing this together, that would be great.
I'm thinking of doing a cool power point presentation and getting them in a room to talk about not clicking on pdf.exe files and etc. 

 It is my understanding that this is how people usually do it?
