I want to grant a student an extension. How do I do that?

There are actually many ways to achieve this. Any time you are viewing student grades you will see a link that says Grant Extensions/Submissions. Clicking on this will help you achieve this goal. Here is a very simple method that can always be used:

(1) Log into WebAssign and click on the "Grades" link at the top and chose the "Reports" submenu.

(2) Select the assignment(s) on the left and the student(s) on the right that you wish to deal with. Click on the "Scores" link near the top.

(3) Click the "Grant Extensions/Submissions" link near the top.

(4) On the resulting page change the due date to whatever you like. If you wish to penalize the student(s) for the extension(s) you can enter a negative value in the +/- field. For example, putting in -5 would decrease the total grade the student can achieve on the assignment by 5 points.
