The typical home report I see around here reports splices in the distribution panel. I have a friend that's a home inspector & he said they were taught about panel splices in class.

I quoted code to him & gave a rough calculation of how many wires and splices you could have in a panel. He said "You really like this stuff, don't you?"

I don't think they're taught NEC at all, I think they're taught what to look for, like a checklist. Sometimes they get confused.
