Refresh cadence

Expected daily

Three distinct Connecticut credential types

DCP's State Licenses and Credentials source contains HIC and NHC registrations and MCO licenses. StateLicense keeps these types distinct and preserves the source status alongside a normalized status.

Search by business name across the three contractor types.
Verify a known credential number and review every returned type.
Check historical and adverse results against the official DCP record.

Source and freshness

The source is the official Connecticut DCP State Licenses and Credentials dataset. The production refresh is expected daily; inspect record timestamps to assess freshness.
