The option to edit the settings of an existing assignment depends on whether the assignment already has submissions from students or not yet.

The overview presented in the table below gives details on which setting can and cannot be modified in an existing Brightspace Assignment, without submission and with submission.

The following steps are the same for both, an assignment without submissions and an assignment with submissions. The only difference is the settings you will be able to modify (see Which Assignment settings can be modified?).

Navigate to the course where you want to edit the assignment. Then, in the green navigation bar,

1. Click Assessment, a drop-down menu will appear
2. Click Assignments

This will lead you to the Assignments homepage. Here, navigate to the existing assignment you want to edit.

3. Click the downward arrow next to the assignment name
4. Click Edit Assignment from the drop-down menu

This action will open the Assignment's settings page.

Whether a Brightspace assignment has submissions or not, but you made changes to its settings, to finish the editing process click the button Save and Close at the bottom of the page for the changes to take effect.
