The reviewer(s) would point out mistakes that I made in the report i.e. saying something is not present and then giving it a good rating. I did not have to change my report and send back to customer as I may have made it sound. They simply point out inconsistencies in the candidates reports to make them aware of their mistakes.
Now that makes sense. Sounds better than your first post where it appeared that they mandated it, or else. Same thing that I do. It’s your business and your business decision alone as to whether you change the report.
I would however, strongly suggest that if any change is made by you (no matter how inconsequential or inconvenient you may believe it to be) that an immediate notice be sent to the client, fully explaining the reason for the change.
