Please merge this idea and K12OR-I-769. They are both asking for the same thing.

This idea was originally suggested in 2016 and has not had any feedback on it. We have had teachers go back and change a grade book grade so that then it doesn't match what was reported on a report card. There should be an open date and a closed date for editing purposes.

Yes!  At the very least, give a warning that the teacher is about to change a grade in a prior term.

The administration should have the ability to set the specific date upon which the grade book's are locked.  We would do it after the year is complete, but other schools might prefer after each term.
