Someone who was my head band director when I was an assistant, but is now fine arts director in a different district. Do I list them as "Director of Fine Arts, New ISD" or "Former Director of Bands, Old MS"?
What if they have retired? "Formerly principal, My School"? Or just "Retired Principal"? He'll tell you his current job title is Couch Commander or Bass Destroyer, depending on the day, but he'll give me a great reference.
