List_of_school_districts_in_Illinois
The following is a list of school districts in Illinois. As of July 1, 2023[update], there were 852 public school districts, including 368 elementary districts, 97 high school districts, 386 unit districts, and one Illinois Department of Juvenile Justice district, and two cooperative high schools.[1]
These districts are organized by regions set by the Illinois State Board of Education and not by the actual county boundaries; school districts can cross county boundaries, and school districts with administrative headquarters and/or schools only in certain counties can include territory in one or more other counties that do not have schools operated by that district.
