tracking students at the class level

Hi everyone,

We have a wish to track a group of constituents in Tessitura.  They are students in a class, and we’d like to group them at the class level (such as ‘member of Mrs. Smith’s 5^th grade class’), and not just that they’re students at the school.  It’s easy enough to affiliate the students to the school using a school/student affiliation, and then I was thinking of using an attribute to group them at a class level.  Or do you think I’d be better off creating an organization account for the class, and affiliating the students (and associating the class account to the school account)? 

Cheers,

Kathleen
