- Fixed?
- The latest correction deadline was May 17, 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.

Medium means the middle half of Chicago-area’s 1,948 licensed centers by state-licensed capacity: 49 to 118 children. Small is 8 to 48; large is 119 to 487.
The ages on the license are what the state licenses it to care for, which can be wider than the ages it takes.
