Tracking changes over time will be very messy. All rules will apply to reporting for faculty and staff as well. This information is usually entered to the payroll system by a department secretary. The current payroll system defines codes for only the five usual groups. Individuals with other codes entered, or no code, who are at Boulder are asked by letter to place themselves in one of five groups.
Practices differ somewhat at the other campuses.
When and how to ask current students, faculty, and staff the new questions How to enter and store the information in SIS, any new student system, ASP, etc.
