Fishers's quickly growing population has created a need for a similar growth in the number of schools within the district as well as additions to existing schools. In 1996 there were four elementary schools, one middle school, one junior high school, and one high school. With the openings of Riverside School and Fishers High School in the 2006-2007 school year, the school district has eleven elementaries, two intermediate schools, two junior high schools, a middle school(the combination of intermediate and junior high school), and two high schools. Prior to Fishers High School's completion, it temporarily served as the freshman campus of the other high school, Hamilton Southeastern High School. The two high schools now compete for the Mudsock trophy, named after the town's original name, and is won by winning against the other school in the most sports throughout the year.
