Attendee types are added to a registration and will impact Instructor assignments for a specific event. The instructor must register for the event before the Attendee type can be added. If you Copy changes to Member Profile, the type becomes a Member Type, not an Attendee Type.
Note: Attendee types should be used with caution. Currently, there isn't a report to see who has an Attendee type. You can add the Attendee Type column to the Attendee or Entries screen along with Types to view the difference between Member and Attendee Type.
See Instructor Assignments for setup instructions and use cases.
