The highlighted and tabbed books in this package are designed to support the type of navigation candidates need during an open-book examination. Highlighting can make important information easier to identify, while tabs can help candidates move more efficiently between commonly used sections.

Open book does not mean that preparation is unnecessary. Candidates have 180 minutes to complete 85 scored questions, so spending too much time searching for individual answers can create time-management problems. Regular practice with the books can help candidates recognize where information is located before exam day.

Licensing Steps

Oklahoma plumbing licensing is administered by the Oklahoma Construction Industries Board. Individuals seeking the Residential Plumbing Journeyman classification generally begin by training and working in the plumbing trade while accumulating qualifying experience.

The typical path begins with working as an apprentice under a licensed plumbing contractor. Experience gained toward licensing must meet applicable Oklahoma requirements and be properly documented.

After meeting the experience requirements, the applicant submits the appropriate plumbing journeyman application to the Oklahoma Construction Industries Board. The Board reviews the application and determines whether the applicant is eligible to take the journeyman examination.

Once examination eligibility is approved, the candidate receives information for scheduling the required examination with the authorized third-party testing provider.

After passing the applicable examination and completing the remaining licensing requirements, the applicant can proceed with the Residential Plumbing Journeyman licensing process.

A licensed plumbing journeyman performing plumbing work in Oklahoma must perform that work under a licensed plumbing contractor. Journeyman experience gained under a contractor can also contribute toward qualifying experience for individuals who later pursue a plumbing contractor license.

State Requirements

Applicants for an Oklahoma plumbing journeyman examination must be at least 18 years of age and meet an approved experience pathway.

One standard qualification path requires three years of experience in the plumbing trade while employed by a licensed plumbing contractor. Oklahoma also recognizes equivalent verifiable plumbing experience obtained while serving in the United States military and certain current, good-standing out-of-state plumbing licenses.

Qualifying formal plumbing education may substitute for a portion of the required experience. An approved associate degree or Career Tech diploma involving a minimum of 1,000 classroom hours may substitute for two years of experience. An approved Career Tech plumbing program involving at least 500 classroom hours may substitute for one year of experience.

When a licensed plumbing journeyman performs plumbing work, that work must be performed under a licensed plumbing contractor. A residential journeyman does not independently operate as a plumbing contractor or independently furnish labor and materials as a contractor.

The Residential Plumbing Journeyman classification applies to residential plumbing work within the scope established by Oklahoma licensing rules. License holders are responsible for remaining within the limitations of their classification while performing regulated plumbing work.

Oklahoma also requires licensed plumbing journeymen and contractors to complete continuing education as part of maintaining their licenses. Current state requirements call for six hours of continuing education within the 36 months preceding license expiration.
