Mr. Rose shared with me a tip that I wanted to share. I’m a little late, but I hope this helps someone.

So I’ve been trying to figure out how to duplicate the groups I’ve created in the grade book in PowerTeacher and I found out how. Simply go back to the assignment that you created the group and edit the assignment. Go to the students tab and at the bottom it says duplicate. By hitting this button another window will open up for you to edit a new assignment with the group you duplicated from.

Happy Grading!
