The Oklahoma Residential Contractor Plumbing and Natural Gas examination is an open book test. The Plumbing Business and Law examination is also open book. Candidates are responsible for bringing permitted references to the examination center and following the testing provider's reference-material rules. :contentReference[oaicite:6]{index=6}
For the Residential Contractor Plumbing and Natural Gas examination, the approved reference list includes the International Residential Code for One- and Two-Family Dwellings, 2018 Edition with Oklahoma revisions; Code of Federal Regulations - 29 CFR Part 1926 with applicable amendments; and Mathematics for Plumbers and Pipefitters, 8th Edition. These trade references are included with this rental package. :contentReference[oaicite:7]{index=7}
Reference materials may be highlighted, underlined, and indexed before the examination. Permanent tabs may be used.

The highlighted and tabbed books included with this rental package can help candidates practice using the same navigation approach during study. An open-book exam still requires preparation because searching through unfamiliar references for every answer can consume significant testing time.
Oklahoma plumbing licensing is administered by the Construction Industries Board. Applicants begin by meeting the applicable age and experience requirements and submitting the required plumbing examination application to the Board. The Construction Industries Board determines eligibility before applicants proceed to examination scheduling. :contentReference[oaicite:9]{index=9}
After the application is reviewed and approved, the applicant's information is forwarded for testing. Contractor applicants are required to pass the applicable plumbing trade examination and the Plumbing Business and Law examination. :contentReference[oaicite:10]{index=10}
After successfully completing the required examinations, an Oklahoma plumbing contractor license remains inactive until the Construction Industries Board receives the required bond and insurance documentation. An active plumbing contractor must maintain a $5,000 corporate surety bond payable to the Construction Industries Board and provide evidence of at least $50,000 in commercial general liability insurance. :contentReference[oaicite:11]{index=11}
Once the licensing requirements are completed and the contractor license is active, the licensee must continue operating within the authorized residential scope and comply with applicable state licensing, insurance, bond, and continuing-education requirements. Oklahoma requires plumbing journeymen and contractors to complete six hours of continuing education within the 36 months preceding license expiration. :contentReference[oaicite:12]{index=12}
Applicants for an Oklahoma plumbing journeyman examination must be at least 18 years old and generally must document three years of qualifying experience in the plumbing trade while employed by a licensed plumbing contractor. Oklahoma also recognizes certain equivalent military experience and provides specific education substitutions for portions of the experience requirement. :contentReference[oaicite:13]{index=13}
Applicants for a contractor license must meet the same qualifying requirements as a journeyman applicant and have an additional one year of lawful experience in the plumbing trade. The Construction Industries Board specifically applies this additional experience requirement to contractor applicants. :contentReference[oaicite:14]{index=14}
For the residential classification, Oklahoma states that residential plumbing contractors meet the same requirements as applicants for the residential journeyman examination plus the additional year of experience. A residential plumbing contractor may operate as an individual, firm, partnership, limited liability company, corporation, or other legal entity while engaging in plumbing contracting within the residential category. :contentReference[oaicite:15]{index=15}
The residential license scope applies to qualifying plumbing work for detached one- or two-family dwellings and multiple single-family dwellings such as townhouses that meet the applicable residential limitations. Residential license holders may not perform plumbing work beyond the scope of the residential license except when working as an apprentice under the required supervision of an unlimited license holder. :contentReference[oaicite:16]{index=16}
Start your trade-exam preparation by becoming familiar with the structure of the International Residential Code. Practice locating plumbing and fuel-gas provisions rather than relying solely on memorization. Work through subjects involving water distribution, fixtures, drainage, vents, traps, piping materials, water heaters, backflow, gas piping, and related residential installations.
Use Mathematics for Plumbers and Pipefitters while practicing calculations. Candidates should be comfortable applying trade mathematics to areas such as dimensions, area, volume, pipe offsets, and other calculations associated with plumbing work.
Safety preparation should include regular use of 29 CFR Part 1926. Become familiar with where important construction safety requirements are located and practice finding information involving ladders, fall protection, protective equipment, excavation safety, tools, and jobsite responsibilities.
Business and Law preparation requires a different study approach. Review bidding, estimating, contracts, project supervision, financial concepts, payroll, labor requirements, insurance, bonds, licensing, and lien-related subjects. Use the Oklahoma-specific laws and regulations alongside the NASCLA guide so that state requirements receive appropriate attention.
Timed practice can also help. The Residential Contractor Plumbing and Natural Gas exam provides 180 minutes for 85 scored questions, while the Plumbing Business and Law exam provides 120 minutes for 50 questions. Practicing with the books under timed conditions can help candidates become more comfortable deciding when to answer from knowledge and when to consult a reference. :contentReference[oaicite:25]{index=25}
