Frequently asked questions about Illinois school districts

How many school districts are there in Illinois?

NCES EDGE maps 863 Illinois school districts with geographic boundaries for the 2024-2025 school year. 849 are unified PK-12 districts, 2 are elementary-only, and 12 are administrative entities. The count does not include statewide charter LEAs, which NCES tracks separately but does not map geographically.

What is the biggest school district in Illinois?

By number of schools, Chicago Public School District 299 is the largest in Illinois with 645 public schools. By land area, Jasper County Community Unit School District 1 covers about 1,167 km² with 4 school(s).

How do I find out which school district my address is in (Illinois)?

Type your address into the search box on the map above and press Find my district. The map drops a pin and highlights the district boundary that contains your address — the popup shows the district name, grade range, and public-school count. The match comes from a point-in-polygon query against the live NCES EDGE boundary service, so it reflects the current official geography.

Are charter schools included in this Illinois map?

Brick-and-mortar charter school campuses appear as individual points when you toggle on “Show public schools” — they are counted in the 4,439 public school total. However, statewide charter LEAs do not have a single geographic boundary, so they are not shaded on the choropleth. If a charter campus sits inside a district’s boundary, it will show as a point but the boundary reflects the standard district, not the charter.

What is an NCES LEAID?

The LEAID (Local Education Agency ID) is the 7-digit federal identifier that NCES assigns to every school district. Illinois district LEAIDs all start with 17 (the state FIPS code). The NCES LEAID is what you’ll see used in federal data releases, the Common Core of Data, and Title I funding records.

How often is this Illinois school district data updated?

The map pulls straight from the NCES EDGE FeatureServer, which NCES refreshes roughly once per school year after district boundary filings are reconciled with the U.S. Census Bureau’s TIGER/Line program. Boundary changes (annexations, splits, consolidations) show up in the next annual release. The current vintage is school year 2024-2025.
