As a father of 4, there is truly a process for the changing of diapers. If you fail to follow the process, it many times is a self critiquing item.

:truce:
On a serious note, there actually are specific infection control procedures that each worker should be using when not only changing the kids, but how they handle other body fluid issues. Things like runny noses, sick kids, food handling, etc. Its a matter of looking at their procedures and verify that they are trained and using them correctly.
As for the HR stuff, others have already touched on them.

PS - Yes, I have fail the diaper changing process and it was "CRITIQUED" by my son.
