Grade locking

Locked after

Date after which the grades will be locked. Usually this date is set to the end of the activity, and the beginning of the grading process.. A typical sequence of events would be:

Event	Locked	Hidden
Start of activity and participant submissions	No	Yes
End of activity and beginning of grading/feedback	Yes	Yes
End of grading/feedback, and release of grades	Yes	No

Effects of locking

Locking prevents changes to grades. It disables the "quick grading" and "quick feedback" features of the Grader report, and prevents modules from updating grades. Locking affects grade items and grades differently, as outlined below.

In grade categories

Locking has no effect on the category itself, it is only used to affect a large number of grade items at once (bulk action), which in turns locks all their grades. The locking effect cascades down to all the category's children. If the category contains categories, the locking effect continues to cascade down, locking all categories, items and grades below the initial category. A grade item can be unlocked even though its parent category is flagged as locked.

In grade items

A locked grade item doesn't accept changes to its settings or grades from its related module. When there is no related module (as for manual grades), the locking simply prevents grader report users from changing the grade using the grader report interface.

In grades

If a grade item is locked, its grades are also locked, and cannot be unlocked until the grade item is also unlocked.
