Can someone with experience answer this?  I am applying for a police department and was given a background packet to fill out.  Everything seemed to go fine the first week my background investigator worked on my personal history.  Now I found out there may be something in my past that will disqualify me.  I am thirty five years old and don't remember every thing minor in my past, however I am being as honest with the background investigator as I remember.  My question is, if I fail backgrounds with this department is there any way to find out what I did or didn't do so I can submit it on my next background packet?  How can I disclose everything in my past if I honestly don't remember or don't know about it?  Please help, I am trying to be as honest with these people as I can...thank you

Usually diqualifiers are pretty major things, things that I believe 99% of us would remember doing.  I find it hard to believe that you would not remember such a thing, as I am sure the BG investigator would too.  It would appear to me and more than likely to the investigator that you are hiding something or attempted to hide something and are hiding behind the pretense that you forgot.  Remember disqualifiers are not petty things.

As for disclosure of why you were dq'd, it depends on the department you applied with, some will tell you why, while others will not reveal anything about it.
