I have read through a ton of d.o.d. and cia policy concerning polygraph results and disqualifcation from the hiring process.  Posts by NSAreject etc. seem to suggest that these agencies cannot reject you purely based on polygraph results if no admission is given.  If one were to take 3, 4, or 5 polygraphs in which no admission was made, but dispite speaking the truth, the individual never passed.....could this individual be failed purely on the basis of polygraph results?  Especially if the background investigation etc does not back up the suspicions?

D.O.D policy seems to state that if one that is already an employee, one can not be fired based on polygraph results, but little is mentioned about those in the hiring process.  And regardless of D.O.D policy, the NSA and CIA (i do understand the cia is not under the dod) have many congressional exemptions.  Anyways, it seems like post people who were failed on this site, made the mistake of an admission or they voluntarily quit the application process.

For those who stay in the process and submit themselves to multiple polygraphs, is there any hope that the polygraph can not be the all deciding factor and instead the background investigation would be focused on?
