We would like to be able to hide grades from parents during the year with the option to make them visible during specific time periods. However, we allow parent to see the content of a class year round.

It is my understanding that teachers have the ability to hide grades in their grades schemes,  however, we allow students to see their grades year round, so this option doesn't solve our problem either. 

 

Is it possible to hide grades from observers with the ability to turn it on during specific times??
