Many students know their teachers/tutors/lecturers etc. - at
uni.
In mainly the prestigious ones.
Obviously, these learned influencers have to pass on their knowledge - and expert opinions, to merit their existence
Other centres of education though - pass on the results of papers to accredited and independent bodies.
These have no idea where the paper came from - college or individual; so anonymity is clear. Simply they look at quality and pedigree of the paper(s).
Education also needs a good look...
