The visibility of quiz grades can only be managed via quick settings on the class page - see Method 2 below.
Each activity or grade item has an ‘Edit’ link under ‘Actions’. The assignments ‘Edit’ action gives two options – ‘Edit Settings’, and the Hide/Show ‘eye-con’. When ‘Hide’ is selected, students will not be able to see their grade and the item will appear greyed out in the gradebook when class tutors look at it. When 'Show' is selected, students will be shown their grades.
The symbol shows the current status of the grades:
The word offers the option to change the current status:
Make sure the category or class total is also hidden to ensure no partial grades are shown to students
Hidden grades will still appear in the class tutor’s gradebook, of course, but in a lighter grey font as an indication that they are not visible to students.
Making grades visible at a prearranged date and time
Myplace can even make grades visible to students at a specific date and time, so you can tell your class in advance when to expect their results. Start by going to the grade item's settings from the gradebook.
Unless your assessment activity is set to the ‘Show’ state, students will not able to see their grades on Myplace. The date setting does not override the overall show/hide setting.
