This is what happened to me....any suggestions???

[T.M. Cullen]

Then, listening to "Larry" and the other so called false positive "experts" on this board

According to Sackett, "false Positives" don't happen much.  But he is a polygrapher and biased.  Listen to what the scientific community concluded:

False Positives with "Suspicious" Thresholds Polygraph screening protocols that can identify a large fraction of serious security violators can be expected to incorrectly implicate at least hundreds, and perhaps thousands, of innocent employees for each spy or other serious security violator correctly identified.

Furthermore, if you end up failing the test, or getting an "inconclusive", despite the fact that you were telling the truth, you'll have first hand knowledge regarding the validity of the test.  

You can be truthful, yet fail the test.

But coming on this board looking for polygraph information is like going to an AA meeting to find a drinking buddy.

There is a lot of good info on this website.  Interested in knowing what the scientific community has to say about the test?  Read the NAS report which you can access from this board:

I hope you get hired?  Be advised that you dealings with the polygraph will not end with being hired.  You have to take the test every 5 years, so the more objective info you can assimilate about the test, the better.
