Tennessee to Oklahoma: journeyman plumber license reciprocity
Tennessee does not issue a statewide journeyman plumber license, so there is nothing to transfer. Here is Oklahoma's standard path for out-of-state applicants.
Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Out-of-state plumbing journeyman without a reciprocity agreement (all states except Arkansas)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A journeyman from any state other than Arkansas has no reciprocity route, because CIB publishes only the Arkansas plumbing agreement and OAC 158:30-5-4 requires a written agreement for the specific license sought. Under OAC 158:30-9-1.4 a journeyman from a state without an agreement, or from a jurisdiction with only local licensing, may request exam equivalency; if the Board has previously approved that jurisdiction's exam as substantially similar, the Oklahoma journeyman exam is waived on a certified letter from the licensing jurisdiction showing a current license in good standing, the license category, an exam score of 70% or higher and no pending discipline. CIB does not publish which jurisdictions' exams have been approved, and no equivalency form exists on the Plumbing Forms page. Otherwise the applicant files the Application for Plumbing Examination with notarized experience affidavits and a copy of the out-of-state license, which 'may expedite processing of the requirements' (OAC 158:30-9-1(k)(3)); out-of-state experience lawfully obtained counts toward the three-year requirement. The applicant pays $75 and must pass the Oklahoma plumbing journeyman exam through PSI with 75%. Oklahoma has no separate law exam for journeymen.
Vendor sites claim Oklahoma plumbing reciprocity with Texas, Colorado and Louisiana; none of those states appears on any CIB plumbing page, on the Plumbing Forms page (which offers only an Arkansas reciprocity application) or in OAC 158:30, so they are treated as default-path states here. Colorado's Plumbing Board has no reciprocal agreements at all. Which jurisdictions' exams the Board has approved for equivalency could not be confirmed from an official page. The exam pass mark is 75% under OAC 158:30-9-1(d), but the equivalency letter only needs a home-state score of 70% or higher. The exam code edition was in transition per CIB's '2026 Building Code Updates and Examination Transition Period' notice.

How Oklahoma licenses journeyman plumbers
Oklahoma journeyman plumber · “Unlimited Plumbing Journeyman”
Statewide license
Issued by Oklahoma Construction Industries Board (CIB), Plumbing Division
Oklahoma issues statewide plumbing journeyman licenses through the Construction Industries Board (CIB) under the Plumbing License Law of 1955 and OAC Title 158, Chapter 30, in Unlimited and Residential categories. An Unlimited Plumbing Journeyman applicant must be 18 and show three years of verifiable experience in the plumbing trade while employed by a licensed plumbing contractor (about 2,000 hours per year, so roughly 6,000 hours; Oklahoma hours count only while registered as an apprentice), or equivalent U.S. military experience, with a Committee-approved 1,000-hour program substituting for two years and a 500-hour program for one year. The applicant pays $75 ($25 application plus $50 initial license), and must score 75% on the Oklahoma plumbing journeyman exam administered by PSI ($92 per portion). CIB has one published plumbing reciprocity agreement, with Arkansas (effective October 21, 2024, journeyman only); other out-of-state journeymen may seek exam equivalency if the Board has approved their jurisdiction's exam, and a current out-of-state license otherwise expedites processing of the experience requirement. Journeymen must work under a licensed plumbing contractor, renew annually ($75) and complete six hours of continuing education every 36 months.
Why Tennessee has nothing to transfer
Tennessee journeyman plumber · “Journeyman plumber (city or county card only)”
Licensed by cities and counties
Tennessee has no statewide journeyman plumber license. The Board for Licensing Contractors licenses plumbing at two other levels only: the Limited Licensed Plumber (LLP), a personal license for projects under $25,000 in municipalities that use the Division of Fire Prevention for permits and inspections (T.C.A. § 62-6-403; photo ID, SSN, Prov LLP trade exam, $75 initial fee; general maintenance under $500 is exempt), and the contractor license with the CMC-A (plumbing) or CMC (full mechanical) classification, a business license required for plumbing work of $25,000 or more. The Board's LLP page tells applicants to check first whether the local government accepts the LLP or runs its own licensing. Journeyman plumber cards therefore exist only where a city or county examines plumbers itself. Metro Nashville's Mechanical, Plumbing, and Electrical Examiners and Appeals Board issues journeyman plumber (and apprentice plumber) certificates; Knoxville registers State Contractors, homeowners, or Unlicensed/State Limited License (LLE or LLP) holders to pull permits and does not publish a separate city journeyman plumber card on that page. An out-of-state journeyman plumber license has no state-level recognition in Tennessee: the Board's trade-exam-waiver form cannot be used for the LLP, and none of the city pages reviewed here publish a reciprocity or exam-waiver path for inbound journeymen.
How local licensing works in Tennessee
How local licensing works. T.C.A. Title 62, Chapter 6 gives the Board the CMC/CMC-A contractor license (business, $25,000 and up, accepted statewide for contracting) and the LLP (individual, under $25,000, only where the State Fire Marshal inspects). Cities and counties that run their own plumbing inspection programs may require a local journeyman or master plumber card instead of, or in addition to, the LLP. Each local card is valid only in that jurisdiction. The Board publishes no journeyman-to-journeyman reciprocity.
Nashville / Davidson County. The Mechanical, Plumbing, and Electrical Examiners and Appeals Board (Metro Code Chapter 2.76) examines applicants for master plumber, journeyman plumber and apprentice plumber certificates and issues those certificates (Codes and Building Safety, 800 President Ronald Reagan Way; 615-862-6500). Expect to sit Metro's exam unless Codes staff confirm otherwise.
Knoxville. Permits are pulled under a State Contractor registration, a Homeowner registration, or an Unlicensed / State Limited License (LLE or LLP) registration. The Plans Review & Inspections page does not describe a city-issued journeyman plumber license. No experience hours published. No out-of-state exam waiver. Accepted only where the Division of Fire Prevention inspects; many larger cities do not use that program.
