West Virginia to District of Columbia: journeyman plumber license reciprocity
District of Columbia has no reciprocity agreement with West Virginia. A West Virginia journeyman plumber applies by endorsement.

Out-of-state journeyman plumber from a state other than Maryland
The board reviews your out-of-state credentials case by case. Some exam is usually still required, often only a law or code exam.
The Board of Industrial Trades publishes a plumber-specific reciprocity bulletin only for Maryland. A journeyman plumber from any other state applies through the DLCP online portal as a new applicant with a passport-style photo, government ID, certificate of completion and/or employment verification letter, and the $65 application fee, must show the 8,000-hour/4-year apprentice experience (or a mechanical-engineering degree plus 2 years, or equivalent), schedules the journeyman exam with PSI, and pays the $110 license fee. Two statutory routes can waive the exam: § 47-2853.122(b-1) requires the Board to accept a national certifying organization's journeyman plumber certificate (completed apprenticeship, passed that organization's exam, designated journeyman, no discipline) in lieu of the exam and subsection (b), and § 47-2853.12(b) directs boards to waive the exam for a licensee in good standing of a state whose standards were at least as high as the District's and which admits DC licensees in a like manner, with § 47-2853.08 leaving the substantial-equivalence finding to the Board case by case. No District-law exam applies.
PSI exam fee is referred to 17 DCMR § 3500.3 and was not stated on the board page. Virginia plumbers are not named in the Reciprocity section or in the Maryland plumbing bulletin title.

How District of Columbia licenses journeyman plumbers
District of Columbia journeyman plumber · “Journeyman Plumber”
Statewide license
Issued by DC Board of Industrial Trades (Department of Licensing and Consumer Protection)
The District of Columbia issues a person-held Journeyman Plumber license (the Board also licenses journeyman gasfitters as a related specialty) through the Board of Industrial Trades in the Department of Licensing and Consumer Protection (DLCP), the same board that licenses electricians and refrigeration mechanics. Under D.C. Code § 47-2853.122 a journeyman plumber must have worked as an apprentice plumber or gasfitter at least 8,000 hours over at least 4 years (a mechanical-engineering degree plus 2 years of practical experience verified by a licensed master, or comparable experience the Board accepts, also qualifies) and then pass the PSI-administered exam, unless the applicant presents a national certifying organization's journeyman plumber certificate that waives both the exam and the subsection (b) experience path. Fees are a $65 application fee and a $110 license fee for a term of up to 2 years; plumber and gasfitter licenses expire March 31 of even-numbered years. The Board publishes a Maryland plumbing reciprocity bulletin; the Reciprocity section of the board page still describes only Maryland and Virginia electricians. No District-law exam applies to journeyman plumbers (§ 47-2853.12(c)(3)).
