Sorry, I should've included this, I was trying to keep things fairly high-level as I had already written far too much. The clearance currently required is NPPV3 (although it might need to be higher in future). I can't find a nice concise description of what it covers, but there are a few documents floating around that refer to it: https://duckduckgo.com/?q=non+police+personnel+vetting+level+3 https://duckduckgo.com/?q=non+police+personnel+vetting+level... It's fairly standard criminal record and family/financial background checking. We've yet to have a person fail.
