Thanks for the clarification and for the mention of the File method you mention. That is connected to the other query I made last week about groups. I've always used random allocation in the past, which works fine, but then we meet after students have completed their assessments, and I want students to be able to get a chance for face to face follow up with their assessors. With ungrouped random allocations, this results in students having to scurry around the room like ants to find their assessors.
So I'm trying it with predefined groups, so that the same 3-4 students are reading each others' papers. Because I'm using groups, I wouldn't need to use File in that instance, but if I weren't using groups, it would be nice to have the same person reading someone's second draft who had read the first draft, and File would accomplish that.
