Alabama to Oklahoma: journeyman plumber license reciprocity
Oklahoma has no reciprocity agreement with Alabama. A Alabama journeyman plumber applies by endorsement.

Out-of-state plumbing journeyman without a reciprocity agreement (all states except Arkansas)
The board reviews your out-of-state credentials case by case. Some exam is usually still required, often only a law or code exam.
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.
