After making changes to a previously used marking guide that has already been used for marking, a warning message is supposed to appear. Testing steps indicate that you will be presented with two options ('Mark for regrade', 'Do not mark for regrade') when attempting to save after making changes to the Marking Guide Title, Description as well as Criterion Title, Description, and Points (provided the criterion still add to the same vale as before changes were made).

I ran this test twice on the Q&A site and twice, no warning message appeared as indicated in testing step 13 (after changing the marking guide name/description and the criterion name/description/point values).

Steps to Repeat: 

Test Pre-requisites:

• An existing assignment set to use a marking guide with a complete guide defined, and some marking completed.
• The marking guide must include at least two values for Frequently used comments and two criterion, adding up to a total score of 100.
• Unless otherwise specified testing should be performed as a teacher user.

Test Steps: 

1. Open the marking guide for editing
2. Change the order and text of the frequently used comments on the marking guide
3. Save the marking guide
4. View existing marking records and check that nothing has changed
5. Open the marking guide for editing
6. Change the name of the marking guide
7. Change the description of the marking guide
8. Change the name of a criterion
9. Change the descriptions for students of a criterion
10. Change the descriptions for markers of a criterion
11. Change the maximum mark allowed for both criterion, making sure that the total marks across all criteria still add up to the maximum mark defined for the assignment
12. Save the marking guide
13. Check that a warning has appeared telling you that this marking guide has already been used for marking and that you are presented with two options ('Mark for regrade', 'Do not mark for regrade')
