In the Faculty module, teachers can only look up a student by going to their class/group rosters. Full time teachers have multiple classes/groups, which makes this a time consuming task. They should be able to quickly look up a student without having to memorize which specific class/section that student is in.
Giving our teachers access to people finder in Academics or Core is not an option as there are functions in both of those modules that they should not have access to.
