There are many cases in which it is useful to restrict access to material in Moodle. For example: sharing information with graders or keeping extra material hidden, some professors need to sharing homework solutions with graders.

Additional Notes
Restricting Topics
It is possible to add a group restriction on a topic or week. Follow the same procedure as above, but set the restriction on the entire topic. You will need to leave the topic and all its contents visible, but Moodle will display a label indicating that access to the topic is restricted. You do not need to adjust the permissions/restrictions for any of the items within the topic. If the topic itself is restricted so will all the contents of the topic.
Viewing as a Different Role Doesn't Work as Expected
Roles and Groups in Moodle are two different things. It is possible to switch your role to see what a Student or Grader sees, but it is not possible to set a specific group. Because we can only restrict visibility based on groups, it isn't possible to verify that the visibility of a topic or item based on group membership.
