On the master student screen, there are several flags you can check (depending on the student, etc). These flags give you the ability to run reports on subgroups of students (walk-ins, edneeded, etc). Additionally, there are 5 user defined flags that you can also use. The title of each flag defaults to User 1, User 2, etc, however, you can manually assign names to each of these five flags if you choose.

You can use them "as is", but if you do choose to use more meaningful labels, the labels you choose are specific to the district, not the campus. (As a disitrict, all campuses will end up sharing whatever custom labels you associate with these fields).

Click Settings from the main menu, then Edit User Flags and the following screen will appear.

Type in the label you want to appear for each flag (limited to 10 characters or less), then click the Pencil icon to save.
