- January 21, 2026
- On file
- 15 visits since January 2011 — all of them cited findings
- Fixed?
- The latest correction deadline was February 28, 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.
