All students are granted access to your course after they register and enroll using the course ID. As students enroll in your course, their names are automatically added to the roster. If a student enrolls in your course and later drops the course, you can change the student's status so that student can no longer access the course materials.
To prohibit students from accessing your course:
From Gradebook > Grades or Gradebook > Manage Roster, select the box to the left of the student name.
Click Deny Access on the toolbar, or select Deny Access from the options menu.
Notes
When a student does not have permission to access the course, the student appears as inactive in the gradebook roster. Note that inactive students are still enrolled in the course.
If students unenroll from your course, depending on options set for your course, they are either removed from the main gradebook view or they appear in
strikethrough font.
You cannot remove a student's name from the online gradebook roster yourself.
To grant students access to your course again:
From the Gradebook > Manage Roster page, select the box to the left of the student name.
Click Grant Access on the toolbar or select Grant Access from the options menu.
