Let me clarify. There is no single definition of a background check. It can be as simple as an employer contacting previous employers to confirm dates of employment, or as thorough as an FBI or CIA clearance check, or anything in between.

Whether any particular piece of information shows on any given background check depends on what information is requested. You could do 16 different background checks on the same individual, and get 16 different results, depending on what information was looked at. It will NOT necessarily be the same for all checks. As an example, I did not do education verifications on my receptionist candidates and my assistant controller candidates, but I did on my R&D director candidates. On the other hand, I didn't do a criminal background check on my R&D director candidates, but I did on my assistant controller candidates. I didn't do an RVM check on any of the three, but I did on my shipping manager candidates. Even within one type of check there can be different responses. Employer A might ask for all arrests and conviction; Employer B might ask for only convictions; employer C might ask for only felony convictions. There's just no way to say what any given check might reveal unless you know EXACTLY what questions were asked.
