Deleting a Subject permanently removes it and all student work within it. If you want to preserve student work, archive the Subject instead. See Archive or unarchive a Subject.
If a Subject is deleted by mistake, contact Stile Support for help restoring it.
Steps:

Read the confirmation message carefully, then click Delete subject to confirm.
Note: Subjects shared with co-teachers cannot be deleted. In this case, you will be prompted to remove yourself from the Subject instead.
