I need to let a student back into a past term course or let a student stay in a course beyond the end of a term. How do I do that?
After the term ends, change the student's role from "Student" to "Student (Ext Access)".
Do not change a student's role to "Student (Ext Access)" in a current term course before the term ends. Millersville's student information system, Banner, controls course enrollments for current term courses, and therefore, until a term ends, Banner will reset students' roles to "Student" daily.
