Parents can now join their students' Canvas accounts as an observer. Parents can only see their child's accounts and courses. Parents can use this as a direct way to message the teacher, see assignment due dates, see any missing or late assignments, and see the student's current grades. Parents can access on a computer or download the Canvas Parent App on their phone (iOS and Android) and receive notifications about assignments for their students.
