I am a graduate student at a US university, and earlier this week I asked a former undergraduate mentee if in her evaluation I qualified for an "excellence in mentorship" award. She responded enthusiastically, and just today wrote the she finished it. She also offered to let me review it to make sure she's included all pertinent information.
All the past letters of recommendation I've received have been closed-envelope letters that I don't have the opportunity to review, I am not sure how to respond. I trust her to write a good letter, and would probably have little if anything to say, but I certainly wouldn't mind having a chance to be sure.
Basically, years of closed-envelope letters of recommendation have conditioned to feel that it is not appropriate to be able to read your own letter. However, the only reason I know for that is to allow writers to speak freely, without the pressure or awkward situation that would arise if one were to ask for the opportunity to read their own letter. On the other hand, this one was freely offered, and so I am not compromising the writer's ability to speak freely.
Do you see any reason, ethical or practical, to turn down my mentee's offer?
