I am concerned students will see their course grade prior to completing their evaluations.

If grades are entered in Blackboard, they are uploaded to the University system from there. The grades are visible to students in Blackboard only, unless they are hidden (see above). If you enter the grades through Online Services as normal, then student grades are hidden from view in MyDegrees until they have completed their evaluations. This is done via a hold placed on the students grades and transcripts.
