One word that can mean both teacher or student

As part of educational systems there is often a division between two roles:

Teachers or educators give knowledge, while students or trainees receive knowledge.

Is there an abstraction over this distinction that describes simply a person being part of an educational system, regardless of whether it is a student or a teacher in particular?

Edit: In case there is no such general term, what about a word in the context of a single subject?
