There are two basic courses that are relevant to this process, manually created courses and courses created from importing the course from our student information system.
Manually Created Courses
The current teacher or Canvas administrator can make this change
In Canvas, select the course, Settings, People.
Add the new teacher to the course by selecting the +People button, Entering the new teacher's email address and being sure to set the Role to Teacher.
Select Next, then Add Users to complete the process.
The new teacher should receive an email invitation and the course will appear on the teachers Course Dashboard. The new teacher will be able to take over all teaching capabilities of the course.
Imported Courses from the Student Information System
During the school year, the teacher must be added to the master schedule course in the Student Information System. The schools administration staff is responsible for making this change. The teacher enrollment into the course will occur during the nightly data synchronization between the student information system and Canvas.
Outside of the school year
Teachers and/or building administrators may ask for courses to be transferred, reassigned or copied to a new teacher taking the role of a reassigned or retired teacher. It's very important for the integrity of Canvas data that the previous year's course enrollments, including the teacher, remain unchanged. Please copy the course content to the new teachers section. This must be completed by a Canvas Administrator. The new imported course from the student information system must have been created and/or a sandbox course can be created for the teacher to then copy to the new section created from the student information system.
