1. Click on Grades
2. In Manage Grades, Click on the Grade Item you want to restrict. In this example, Quiz 1 - Brazilian geography
3. Click on the Restrictions tab
4.Select "Grade item is visible for a specific date range". Check the box that says "Has Start Date" Enter the correct date and time that you want that grade item to become visible to students when they check grades in D2L.
You can also select an end date if you only want them to see it for a fixed period of time.
You can check display in Calendar as well if you want this grade item to show up in the calendar.
5. Click on Save and Close.
