Joint GSI and Professor Letter of Rec?

[GnomeSain]

Hi all,

I think many have encountered this situation before. I got an A in a class (top 5 out of class of 200) but I hardly interacted with the professor. I did, however, interact with the GSI to a great extent and she seems to personally like me.

Is possible to get a joint LOR, where the GSI can write it while the professor and the GSI both sign it?

Has anyone successfully done this? How should I go about it?

Generally yes, this is possible.

I haven't done this because I went to a small liberal arts school that didn't have grad instructors, but here's how I'd do it. I'd approach the GSI and ask if s/he would be willing to write a letter and have it co-signed by the full professor; tell the GSI why you want her/him to write (i.e., s/he knew you well as a student, you participated a lot in class, etc.) and about your plans for graduate school so that s/he has some direction.

Since the GSI is a grad as well, I don't think it'll take much explaining as to why you want the letter co-signed.
