FBI background checks only provide information on crimes that you were actually convicted of doing.
Unfortunately, this isn't true at all.
I just went thru one for the FAA because of a records snafu and they wanted a full, written explanation for every single time I had ever been arrested or had received a Civil Summons for anything. I have been arrested or received a summons previously for minor stuff and for bigger stuff during a particularly nasty divorce. Looking at the standard federal printout, thay could tell me every single time I had ever been arrested or had received a civil summons in any state, at any age, for any reason. It's all there ... everything ... even though it was all either dismissed, never went to trial, or was plead down to a class three misdemeanor.
If you apply for an airline job and you were told any of the following by a $hit-house lawyer:
"You were under 18 ... it doesn't count"
"It has been expunged ... it doesn't count"
"It was dismissed ... it doesn't count"
And if you check no to a questions about ARRESTS and not just convictions ... you are going to get your heart broken in ground school. I've heard it before here at FlightInfo, and I've heard it in person. Some guy checks NO to the "Have you ever been arrested?" question because someone told him one of the above lines ... gets to ground school and one day they pull him out to ask a couple questions for clarification ... welcome to unemployment.
A Federal Background Investigation packet will inform your employer of every single time you have ever been arrested for anything, anywhere, and at any age, regardless of the eventual outcome ... period.
