Then, to do a background check, you just input those job categories and an applicants ID info and get back a "no adverse events" result, or otherwise get back info on only crimes relevant to the categories specified. My understanding is that is basically how some EU countries do it.
I think companies would welcome this sort of standardization (including how many years it would take for different adverse events to fall off your record) as it would help insulate them from claims of bias.
