Mitch has an interesting post and comments on what is being done to prevent fraud/misrepresentation in certification. Check it. I'm sure many of you are already familiar with CertGuard, which is also referenced in Mitch's post.

Along these same lines, we've been asked to provide more clarity on the MSFT non-disclosure agreement so the legitimate test-takers of the world are clear about what can and can't be discussed under the NDA of taking a MSFT cert exam. understood that it is difficult to respect the "rules" if they aren't clear to start with. See Demystifying the NDA on Michael Alligood's blog...
