The merging of Diller Community Schools and Odell Public Schools began as a high school sports cooperative in the 1998-1999 school year. Beginning with the 2000-2001 school year the schools consolidated academically as well. The Diller Eagles and Odell Tigers then became the Diller-Odell Griffins. The Griffin is a mythical animal that has the upper body of an eagle and the lower body of a tiger or lion, so this was a very fitting mascot for the school. By joining together the schools have been able to offer a greater selection of classes and more clubs. The Diller-Odell high school is located in Odell, and the elementary is located in Diller.
