You can see who's read, who's overdue, and who has not read a policy following these steps:
Click on compliance
then click Overdue.
Click on the required policy.
On the right-hand side, a new window will open up, and you'll see Total Members. This shows you the names of those who are overdue, read, or unread on a policy.
If you can't see the compliance, please ask the person above you to make you an Administrator and not a User for Policies and Procedures. We have a handy article on managing member roles.
