Same with College/University professors. Nothing of monetary value. But hand-written thank-you notes from students? Priceless.
I was nominated for a service award at my University, shortly after they opened it up to faculty (before it was only staff). The nominee was anonymous, and from that and the actual entry, I have to assume it was a student who nominated me. Didn't win my category, it went to support staff, but the very fact that I was nominated was what mattered. My friends on the faculty were so congratulatory, because this was very rare and special.
