The following is a list of school districts in Illinois. , there were 851 public school districts, including 367 elementary districts, 96 high school districts, 387 unit districts, and one Illinois Department of Juvenile Justice district, and two cooperative high schools.
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.
The state classifies Chicago Public Schools as its own classification, and it classifies other school districts in other ways. All school districts are classified as separate governments by the U.S. Census Bureau, and Illinois has no school systems dependent on another layer of government.
