Due to FERPA concerns, our department uses unique ID numbers rather than names or student IDs to identify and return student work. I have the IDs in a spreadsheet and need to add a column in the gradebook, so that TAs can enter the grades by this ID. How do I do this? I tried making it an assignment, but the import does not work. It appears as if it will when I set up the import, but the numbers never actually show up in the gradebook. They are six digit IDs in the form 123-456.
