I have been doing research into graduate programs and have noticed that some departments have a representation of their own PhD graduates as professors while others have an absence.
For example, a department I have looked at in a top university in Canada had a faculty completely composed of PhD graduates from top American schools, but none from its own.
I can see this as a signal of either two things -
- That the department may not want to be seen favouring its own candidates.
- That the department may not have as much faith in its own graduates as that from other schools.
I understand that this may differ from field to field.
But in general, what is the majority view-point on a department that has no representation of its own graduates on its faculty?
