Nauvoo–Colusa Community Unit School District 325 is a school district headquartered in Appanoose Township, just east of Nauvoo, Illinois. It serves northwestern Hancock County, including the city of Nauvoo and the unincorporated community of Colusa.
In 2001, Dallas City High School closed in Dallas City. The Dallas City area was reassigned to Nauvoo-Colusa for high school, so that year 70 students and all but two of the Dallas City High teachers moved to Nauvoo-Colusa High School. The school's enrollment increased to 180 from 111, and all of the classrooms used as storage became active classrooms. The Dallas City district donated equipment to the Nauvoo-Colusa High School.[3] In 2007, the Dallas City, High School Students, converged into the Illini West School District.
In 2007, the Nauvoo-Colusa school district and the Warsaw Community Unit School District 316 agreed to a plan in which Nauvoo-Colusa would close its high school and send its students to Warsaw High School. In return the Warsaw district would close its junior high school and send its students to Nauvoo-Colusa Junior High School.[4] On Tuesday February 12, 2008 voters in both districts approved the deactivation plans.[5] High school students attended Nauvoo-Colusa High School from 1961 to 2008.[6]
In 2015, The Elementary School moved to the Nauvoo-Colusa High School.
