The Approved Assessment function has recently been updated (August 2023) so that once Approved, an assessment is ‘locked’ into Read Only format to prevent a user from unintentionally writing over a past assessment.
This is not the case for Draft Assessments.
If someone wants to add or change an already approved assessment, the Data Manager can choose to ‘Change back to draft’ to make the changes then Approve again to lock it into Read Only.
You can find the ‘Change back to draft’ button on the final screen of the assessment in the same place as Approve Assessment.
To jump quickly to this screen, open the assessment by selecting ‘Update Assessment’ then select the Assessment Flow Button and scroll down the ‘Any other comments’.
