I have 504 students whom I do not assign a due date so I would type in their names under the "Assign to". However, this school year I have way too many students, and typing their names would take too long. I thought about creating a group with all my 504s and SPed but they would be able to see each other and that would be no good. Is there any other efficient way I could add a group of students to an assignment under the "Assign to" without a due date?
