Deleting a Program
It is possible to completely delete a program from the system. That being said, unless you are certain that you want to permanently delete the program, we would recommend instead to changing the program's visibility to "Hide" if you no longer require it.
Step-by-step Guide
To delete a program:
Go to Site Administration > Programs
Click on the "Delete" icon next to the program in question
Important Notes
When you delete a program, all users who were enrolled in a course via that program are unenrolled from the course in question (unless they are also enrolled in the course via other programs and/or enrollment methods).
