Group assignments in Blackboard are great for organizing a learning activity, but often the final work needs to be graded on an individual basis. You can add a group grade for a group assignment, and then, if needed, add a user-specific grade to that assignment.
Find the student and the column for the group assignment in the Grade Center and click the drop-down arrow next to the assignment's name.
Click View Grade Details.
Click Edit User Grade to assign an individual's grade or, alternately, Grade Group Attempt to provide a group score.
