Hi Vicki. You will need to make sure that your organization has the permissions set for your role to be able to enroll other users of that role type. Here is some info on the enrollment process.
@Vicki.M.286 Hi Vicki,
Thank you for reaching out to us on Community.
If you have the required permissions then you can enroll another instructor in your course or reach out to your institutional Admin who can enroll that instructor in your course.
