It's an example but not germane to this process.
The passing score for formal ("real") certifications involves detailed
statistical analysis at the item-level basis combined with expert opinions
of disinterested subject matter experts as to whether a minimally competent
person in that job role should be able to know, apply, or perform a stated
concept or task. This is known as Modified Angoff Scoring and is a common
method for setting the cut score - PMP uses this for example.
