Removing a course takes it off a class's course list, and that's almost all it does. Your students' progress, your assignments and their scores, and your access settings are all kept, so if you change your mind you can add the course back and pick up where you left off. This article walks through the steps and exactly what changes.
Before you start: you can remove courses from classes you own or co-teach. School administrators can view a class's courses but don't get a Remove button.
Remove a course
Click Classrooms in the sidebar and open the class.
Click the Coursework tab, then Assigned Courses.
On the course's card, click Remove (at the bottom of the card, beside Manage access).
Read the confirmation. Its title asks whether to remove the course from this class, and it explains: "Students won't see this course in their course list anymore. Their progress is saved, and adding the course back restores it."
Click Remove course, or Cancel to keep it.
Depending on the course, the confirmation may also tell you how many of the class's assignments use it (for example, "3 assignments use this course. They'll stay in Assignments and the gradebook, and students can still open them."), and, for Personal Finance Core Foundations (3e), that "Twine Town turns off for this class until you add the course back."
A message confirms the course was removed, and its card disappears from Assigned Courses. If something goes wrong you'll see "Couldn't remove that course. Please try again." and the confirmation stays open so you can retry or cancel.
What happens when you remove a course
Students' course list: the course no longer appears on their My Courses page for this class.
Student progress: kept. Every lesson and quiz a student finished is still recorded. If you add the course back, their progress reappears as it was.
Assignments and scores: kept. Assignments that point into the course stay on your Assignments list and in the Gradebook, with their scores, and students can still open them from their Assignments page.
Manage Access settings: kept, and they come back if you add the course back. While the course is off the class, they don't apply, so anything students open from a kept assignment is open.
Other classes: unaffected. Removing a course from Period 1 doesn't touch Period 3, even for a student who's in both.
If the course is Personal Finance Core Foundations (3e), two more things pause:
Twine Town turns off for the class until you add 3e back. See Twine Town: teacher guide.
Certificates: the class's Certificates settings will ask you to add 3e again. Certificates students already claimed aren't deleted, and their verify links keep working. See Course completion certificates.
Be careful with retired editions
If the course you're removing is marked Retired edition, think twice. Retired editions can't be added to a class, so once you remove one you won't be able to put it back. Students' progress in it is still saved, but they won't see the course on their list again. If you're moving a class to the current edition, add the new course first and keep the old one until your students no longer need it.
Adding a course back
On Assigned Courses, click Add Course.
Pick the same course and click Add to your class.
Students see it again on their course list with their earlier progress, and your Manage Access settings for it apply again. See Adding a course to your classroom.
Tips
Want students to stop working ahead rather than lose the course? Lock the later units with Manage Access instead of removing the course. See Manage Access: choosing which units students can open.
The assignment count in the confirmation is a useful check. If it's higher than you expected, cancel and look at Coursework > Assignments first.
Added the wrong course by accident? Removing it right away, before students start, is the cleanest fix.
Common questions
Will removing a course delete my students' grades?
No. Lesson and quiz completions stay recorded, and assignments that use the course stay in Assignments and the Gradebook with their scores.
I removed a course by mistake. Can I undo it?
Yes, as long as it isn't a retired edition: add the same course back from Add Course. Students' progress and your access settings return with it.
Why can students still open lessons from a course I removed?
Because you kept the assignments that point to them. Students can open anything they've been assigned, and your Manage Access locks don't apply while the course is off the class. If you don't want students working on those lessons, delete or reschedule the assignments. See Editing, rescheduling, and deleting assignments.
Can I remove a course for one student only?
No. Courses belong to the whole class. To give one student different work, assign it to that student specifically. See Assigning work to the whole class, a group, or individual students.
Does removing a course affect my co-teacher?
Yes, for that class. A course belongs to the class, so it comes off for everyone who teaches it. Their other classes aren't affected.
