State record — Illinois DCFS

Last visit: May 29, 2026
On file: 6 visits since December 2015 — 1 cited nothing
Fixed?: The latest correction deadline was June 26, 2026. Illinois DCFS does not publish whether it was made.
Most serious: Illinois DCFS does not publish a severity level for a citation, so there is no most-serious to name.

Illinois DCFS cites each subsection of a rule separately, so one audit of a filing cabinet can produce ten citations. It publishes the rule’s title and a correction deadline, but no description of what was observed.
