Hi Christina

I think the best practice is to have separate accounts for adding grades and receiving grades - otherwise the person who can add grades can change the grade on their own account if they have a learner and trainer role in the one account rather than two accounts.

The site logs do show who changed grades so this will be recorded but the records may be difficult to find as every transaction is recorded. 

Is the creation of the extra account causing some issues for you?
