## Licences under the Detective Board

257,863 active licences are regulated by this board — 20.6% of the register, spread over 26 distinct licence categories.

**2,963** of the 257,863 active licences under this board carry at
least one disciplinary action in IDFPR's file — 1.1%.

This site publishes that count and no more. It never names who,
and never says why: in Illinois a licence can be suspended for unpaid state
taxes, child support arrears or a defaulted student loan, none of which says
anything about how someone does their job. The detail is on IDFPR's own record
and on an individual entry here, which has no address a search engine can
reach. [Why that line is drawn there](/discipline.md).
