Statewide license
Issued by West Virginia Division of Labor, Licensing Section (Commissioner of Labor)
West Virginia issues a statewide Master plumber license through the Division of Labor under W. Va. Code 21-14. The statute defines a master plumber as a person who has passed a written master examination with a score of at least 70 percent and who is competent to design plumbing systems and to instruct and supervise journeyman plumbers and plumbers in training; the master written examination may not be taken until one year after passage of the journeyman plumber examination. This is a personal license, distinct from a Plumbing contractor license issued by the West Virginia Contractor Licensing Board under W. Va. Code 30-42 (the Licensing Section administers that board as well). Since January 1, 2009 plumbing work for others requires a Commissioner of Labor plumber license. Out-of-state master plumbers can apply under the reciprocity section of the Division's plumbing rule (42CSR32 section 14), which ties licensure without examination to the conditions of the Review and Credential Acknowledgement Procedures Act (W. Va. Code 21-17-3(a)), including holding a comparable origin license for at least one year. The Division publishes no named plumber partners. Ohio's Construction Industry Licensing Board lists a West Virginia Master Plumber (exam-issued) among credentials that can reciprocate into an Ohio plumbing contractor license; that is Ohio's inbound contractor rule, not a West Virginia master-plumber agreement.

Getting licensed in West Virginia from scratch
No license yet, or nothing that transfers? This is how West Virginia issues a master plumber license to a first-time applicant.
Master plumber license by examination
A West Virginia journeyman plumber becomes a master by passing the master plumber written exam with a score of at least 70 percent, which may not be taken until 12 months after the date the journeyman plumber exam was passed. Neither the plumbing law nor the Division's rule sets any other experience, hour or classroom minimum for the master license. The exam is an open-book, computer-based test given by Prov at testing centers or online through Examroom, and it costs $59.95 per attempt. After passing, mail the notarized Plumber License Application/Affidavit with your exam score report and the $75 license fee to the Division of Labor.
The master exam has 100 questions in 3 hours on the same subject areas as the journeyman exam. Its references are the 2018 International Plumbing Code, the 2018 International Fuel Gas Code, Mathematics for Plumbers and Pipefitters (8th edition) and Plumbing Basics for Contractors (4th edition), and a Spanish version is available. Prov's West Virginia testing centers are in Charleston, Martinsburg, Morgantown and Wheeling; results are given at the end of the exam, and a failed exam can be retaken with no waiting period at the same $59.95 fee. The references may be highlighted or permanently tabbed but not otherwise marked. A master plumber may design plumbing systems and supervise journeyman plumbers and plumbers-in-training. The master license is a personal license and does not by itself let you contract: plumbing work on projects that meet the Contractor Licensing Board's thresholds also requires a West Virginia contractor license with the plumbing classification, which the Division says requires the master plumber or plumbing exam plus the West Virginia Business and Law exam.
