Teachers can add and edit students manually in Manage Users. District Admins can add and edit all user types (students, teachers, admins).
To manually add or edit a user:
Click on Settings and select Manage Users.
Select the User Type and the School.
To edit a user, click the name of user in the Student Name column.
To add a user, click the Add Student + link on the upper right corner of the list (or Add Teacher or Add Administrator, depending on the User Type selected).
Fill out the information window.
Note: student and teacher identifiers must be unique to the district and may contain letters and numbers.
Work with your District Admin to prevent overlap and have a consistent pattern with which to identify students and teachers.
