Hi @jskip Thank You for posting your question here in the Community. Does this Guide help to answer your question? https://community.canvaslms.com/docs/DOC-13034-415257129 If you do not have the "Delete this Course" option available to you, your local Canvas course admins at your school may have removed that option from your view. You would want to contact them directly to see if they could remove that sandbox course for you. I hope this helps, John.
It depends on how the permissions have been set at your institution as to whether or not you will be able to delete courses. Try this: go to your course and click the Settings tab in the lower left part of the screen. Then look at the right side of the page and see if there is a button to Delete the course. If not, you might need to get a local admin to delete them for you.
