Verdict
Full re-application
Kentucky has no plumbing reciprocity or endorsement covering North Carolina, so this is a full journeyman application either way. Kentucky has no plumbing reciprocity; every applicant, including out-of-state plumbers, must pass the Kentucky journeyman plumber examination (written, drawing, and practical sections, minimum 75% each). An out-of-state plumbing license may be submitted only as proof of the required experience, not as a substitute for the exam. The productive plan: gather proof of the apprenticeship or on-the-job hours you logged in North Carolina, register for Kentucky's journeyman exam, and treat your experience as exam preparation and as credit toward Kentucky's experience requirement. Budget a new-applicant timeline and order your certified license history early — it is the long-lead item.
