Anyone doing research on unaccrediteds?

I'm signed up to be a presenter at a series of continuing education events for auditors / fraud prevention specialists.

It's just a one hour bit on accreditation basics, spotting frauds, verification procedures etc.

Just curious if anyone has a survey they are using on identification of fake universities. One of the things I am going to have the audience complete is a ranking of:

Regional Acc
National Acc
State Licence
Unacredited

Then also a list of 10? universities, asking them to spot the fakes.

If anyone has a survey they are currently using, would be interested in seeing it.

Or if it's of benefit to someone, could set it up to line up with any ongoing efforts, and report results back.
