Oklahoma Plumbing Contractor and Journeyman License Requirements

A plumbing contractor is the highest-ranking licensed plumber in Oklahoma; both apprentice and journeyman plumbers work under plumbing contractors to gain verifiable experience to continue on their path of licensure. A journeyman may supervise up to three apprentices and act as the job foreman.

You must have an equivalent and verifiable three years of experience in the plumbing trade while serving in the U.S. military, or,
You must have a verifiable out-of-state plumbing license that is both current and in good standing.

The following education experiences may be substituted for a portion of the experience requirements:

For a two-year substitution:
- An associate degree or Career Tech Diploma that certifies the completion of a plumbing educational program that is:
  - A minimum of 1,000 classroom hours;
  - Approved by the committee.
For a one-year substitution:
- A Career Tech diploma that certifies the completion of an educational program that is:

  - Approved by the committee.

Both contractor and journeyman applicants must submit a Plumbing Application that includes an application for the plumbing examination. The application must include the correct license and application processing fees totaling:

Plumbing journeyman – $75

The fees must be made payable to the Construction Industries Board (CIB), and submitted to:
