Confirm This Is the Right License for Your Work

Every state licensing board defines the exact project types, sizes, and trades that fall under each contractor classification. Review the scope below to make sure this license matches the work you actually do — then enroll in the seminar that prepares you for that exam the first time.

This is not a license that can stand-alone. It is required by the state that individuals who are taking the Plumbing Contractor Exam must also take this exam in order to obtain that license.

License Requirements

The first step in the licensing process is to submit a completed application to the state licensing board to obtain approval to test.

All Mechanical-type Contractors are required to take the Mechanical Business and Law Exam in addition to the contractor’s exam in order to obtain this license.

Specific requirements can be found under the Mechanical Classification for each license.

Reciprocity

The state of Oklahoma does not have any reciprocity agreements for this license.

Continuing Education

Oklahoma currently does not require Continuing Education.

The Exam

The testing company is PSI. It is an open-book, timed test. There are 50 questions and a 2-hour time limit. A score of at least 75% is required to pass the exam. The test fee is $100.00. If this exam is taken at the same time as the Plumbing Contractor’s Exam there is not a separate fee for each exam. If they are scheduled and taken separately, it is $100.00 for each one.

EXAM CONTENT: Bidding and Estimating, Project Management & Supervision, Contracts, Financial Labor & Personnel Risk Management, Payroll & Payroll Taxes, and Licensing Requirements.
