Prevent Teachers to change grades at some point
 

Hello,

Is there a way to prevent the teacher to modify the grades for a specific course at some point? In other words I don't want the teacher to make any changes after submitting the grades or ten days after the end of the course. Is this doable in Moodle?

Thank you,

Elie.
