What 'Class D' Means on KOOL — Why Your Loved One Might Be Listed as Class D (County Jail/Detention Center)

On KOOL, "Class D (CD)" has a specific meaning. KOOL defines Class D offenders as people held in county jails and detention centers. So if your loved one shows up as Class D, that's KOOL telling you they're likely at a county-level facility (a regional jail serving a county, for example) rather than a Kentucky state prison.

Class D is tied to county jails and detention centers, so that's the lane to think in when you see "CD" on a KOOL entry. KOOL also has a separate "Locations" category for offenders housed in state institutions or contracted private facilities. That distinction matters. A Class D label points toward county custody, while "Locations" (as KOOL defines it) points toward state prisons and contracted facilities. They're not the same bucket, and mixing them up can send your search in the wrong direction.

For families, the practical takeaway is straightforward: a Class D status means your next steps should focus on county jails and detention centers. You likely won't find your loved one listed under KOOL's state prison "Locations" category, because KOOL treats county placement (Class D) as its own thing. If you're trying to confirm where someone is being held, start with county-level rosters and county detention booking information, then work outward from there.

1. Start with less information - KOOL’s own search hint is to enter as little information as needed to get a match. Try just a last name first, then add a first name if you get too many results.
2. Double-check spelling and try common variations - If you get no results, check for typos and spacing, and try alternate spellings (including nicknames or other names they may be listed under).
3. Use RESET DATA, then search again - KOOL instructs users that if a search returns no results, you should check spelling, click the RESET DATA button, and redo the search. This can clear out a field or filter that is blocking a match.
