License levels in Kentucky

Kentucky plumber licensing at a glance

RequirementsJourneyman: at least 1 year experience as an apprentice plumber plus a department-approved course covering plumbing practice / the Kentucky State Plumbing Code (generally ~2 years experience total); pass written exam (2.5 hrs) and practical exam (2.5 hrs) at 75%+. Master: hold journeyman experience (generally ~2 years post-journeyman / ~4 years total); pass the master exam (2.5 hrs) at 80%+.
ReciprocityNone, and no examination is ever waived. What Kentucky publishes is an out-of-state qualifying pathway at the master tier only. Under 815 KAR 20:030 Section 2 (last amended effective 12-5-2023) an applicant may qualify to SIT for the Kentucky master plumber examination if the applicant held a valid plumbing license issued by another state for at least two of the preceding five years, or practised plumbing in a master-equivalent capacity for at least four consecutive years in a state that issues no plumbing license at all. Either way the applicant must submit Form PLB-1, pass the Kentucky master plumber examination at 80% or better on every section, and pay a $250 license fee. No states are named; the Division of Plumbing evaluates the documentation case by case. For the journeyman tier there is no out-of-state or reciprocity provision at all: Section 3 qualifies an applicant strictly through two years as a Kentucky apprentice, or a Kentucky-approved course plus one year of apprentice experience, and always requires passing Kentucky's own journeyman examination at 75% or better.
RenewalLicenses renew annually; proof of continuing education (per 815 KAR 2:010) must be submitted before renewal/certification renewal.
