Feedback and grades should be released to all students per assignment, four working weeks after the due date.
There are three actions required to ensure that grades are released as letter grades to all students. Please follow the step by step guidance below.
On the post date, when the grades have been automatically deanonymised by Turnitin and sent to the grade centre in the NILE course, tutors will need to sense-check the grades for the assignment to see if there are any grades that seem anomalous. If this is the case then the existing policy requirements kick in as normal: i.e. the tutor should ZZ the grade and can invite the student for an academic misconduct viva prior to making a referral, if this is appropriate after the viva.
Now that marking and internal moderation is complete, return to the Turnitin inbox and reveal the student identities against each submission made after the due date as indicated in the date column; late submissions will be highlighted red.
Enter a reason for turning off anonymous marking for the selected student. The term 'late submission' will suffice. Use the Reveal button to confirm.
The name will show in the Turnitin inbox.
For each student whose anonymity has been lifted, if the student has an agreed extension and their submission date falls within the boundaries of that extension period, then the grade originally awarded by the first marker and internal moderator remains in place. If the student does not have an agreed extension, or if the work was granted an extension and was submitted outside of the agreed extension period then, depending on how late the work was submitted, the grade will need to be capped prior to being released to the student in line with University policy - see the Staff Handbook (link below) for more details about how to handle late submissions. For each student deemed to have submitted late, return to the Feedback Studio view and overwrite the grade value appropriately.
Please refer to the earlier section of this guide 'Giving feedback and grades to students in Turnitin' for step by step guidance on applying grades and for details of the score to letter grade conversion.
It is important to ensure that the Turnitin feedback release date is set correctly. This setting governs when the anonymity rules are lifted, allowing the grades to be shown in the grade centre next to the relevant student. It also permits students to view their feedback within Turnitin Feedback Studio.
Navigate to the Submit your work area and locate the Turnitin Assignment.
Select the title of the assignment link.
Go to the settings page using the cog icon. Ensure the feedback release date is correct. If necessary, adjust it using the date picker tool or by entering the date in the text box.
NOTE
Take extra care when making adjustments to the post date. If it is accidentally set earlier than the current date, all anonymitiy will be lifted and cannot be re-imposed.
Use the Submit button to save the changes when you are confident the setting is correct.
Check that the grade centre column is displaying letter grades, not scores. If it is displaying scores, set the correct grading schema with the following instructions.
Navigate to Course Management, Control panel, Grade centre, Full grade centre.
The Grade Centre is a table, with students displayed along the rows and assignments down the columns.
To edit a column for the Turnitin assignment, select the contextual menu next to the title of the assignment column header and choose Edit column information.
Locate the Primary Display option and select either UnderGrad or PostGrad letter depending on the academic level of the module.
Use the Submit button to commit all changes.
Prior to the release date, the grade centre column should have been hidden from students when you set up the assignment or graded activity. On the release date, the column will need to be shown to the students following the steps below.
Navigate to Course management, Control panel, Grade centre, Full grade centre.
The grade centre heading should be shown without any images or icons next to it.
If the column heading has an icon next to it with a cross through it, then the grades are not visible to students. 
To quickly make a column visible to students, use the contextual menu next to the heading and choose 'Hide from students on/off' to toggle the visibility.
Your students will now be able to view their feedback and grades.
