Exam Details

The Oklahoma Residential Contractor Plumbing and Natural Gas examination evaluates technical knowledge associated with residential plumbing installations, fuel gas systems, piping, calculations, and construction safety.

The Oklahoma Construction Industries Board administers plumbing contractor licensing, while PSI administers the applicable examination.

  • Exam Name: Oklahoma Residential Contractor Plumbing and Natural Gas
  • Licensing Authority: Oklahoma Construction Industries Board
  • Testing Provider: PSI
  • Number of Scored Questions: 85
  • Time Allowed: 180 minutes
  • Passing Score: 75%
  • Minimum Correct Answers: 64
  • Examination Format: Open book

Important examination subjects include general plumbing knowledge, piping and valves, fixtures and equipment, water supply, drains and sewers, venting, traps and waste systems, isometric analysis, fuel gas, and construction safety.

Candidates should develop familiarity with residential plumbing installations and practice interpreting technical requirements, mathematical problems, piping diagrams, and code tables.

Contractor applicants also have business and licensing responsibilities beyond the technical examination. The included Oklahoma regulatory publications and NASCLA contractor guide support review of those professional subjects.

Open Book Test

The Oklahoma Residential Contractor Plumbing and Natural Gas examination is an open-book test. Candidates may consult approved examination references in accordance with PSI requirements.

Open-book testing requires technical understanding and efficient reference navigation. Candidates must recognize the subject of each question, locate relevant information, and interpret applicable provisions within the examination time limit.

The International Residential Code is particularly useful for reviewing residential water supply, sanitary drainage, venting, fixtures, fuel gas piping, and installation requirements.

Oklahoma adopted the 2024 International Residential Code with applicable state amendments effective September 14, 2026. The examination transition period for affected residential plumbing and natural gas examinations runs from September 14 through December 14, 2026.

During this period, candidates may test using either the previously adopted or newly adopted building code. Beginning December 15, 2026, affected examinations will use the newly adopted codes exclusively.

Approved examination references must comply with PSI requirements concerning editions, highlighting, tabs, binding, and additional materials. The package's prepared books support open-book study and reference navigation.

Not every book included in the rental collection is necessarily permitted inside the technical examination room. The Oklahoma licensing and business references also support preparation for contractor responsibilities outside the technical examination.

Practicing code navigation during study helps candidates become comfortable using indexes, diagrams, mathematical formulas, and technical tables.

Licensing Steps

Oklahoma Residential Plumbing and Natural Gas Contractor licensing is administered by the Oklahoma Construction Industries Board. The Ultimate Package includes Application Service to support customers during the licensing application process.

  1. Review the Residential Contractor Classification: Understand the residential plumbing and natural gas work covered by the license.
  2. Meet Licensing Qualifications: Complete the applicable plumbing trade experience and eligibility requirements.
  3. Prepare for the Technical Examination: Study residential plumbing systems, fuel gas installations, mathematics, and construction safety.
  4. Review Contractor Business Responsibilities: Study Oklahoma plumbing laws, industry regulations, construction liens, and business management.
  5. Complete the Licensing Application: Use the included Application Service for assistance with the applicable application process.

  8. Complete License Issuance Requirements: Satisfy the applicable examination, licensing, bond, and insurance obligations.

Residential plumbing contractor applicants must meet the applicable residential journeyman requirements plus an additional year of qualifying plumbing experience. Approved education and other recognized qualifications may contribute toward eligibility under Oklahoma regulations.

Combining technical study with application assistance helps candidates organize important stages of their licensing preparation.

State Requirements

Residential plumbing and natural gas contracting in Oklahoma falls within the state's regulated plumbing industry. The Oklahoma Construction Industries Board oversees licensing requirements and professional responsibilities.

The residential contractor classification covers authorized plumbing work in qualifying residential buildings. Technical activities include water distribution, sanitary drainage, venting, plumbing fixtures, piping materials, and fuel gas systems.

Natural gas work requires knowledge of fuel gas piping, sizing, pressure regulation, appliance connections, system testing, and applicable installation safety provisions.

The International Residential Code establishes requirements for qualifying residential buildings, including one- and two-family dwellings and townhouses within its scope.

Residential contractor licensing differs from residential journeyman licensing. Contractors have additional responsibilities involving business operations, professional authorization, and compliance with applicable licensing requirements.

Maintaining an active plumbing contractor license also involves applicable bond and insurance obligations, continuing education, and license renewal responsibilities.

The Oklahoma Plumbing License Law, Plumbing Industry Regulations, and other included regulatory publications support study of these professional requirements.
