Master Plumbing Contractor License (Prometric©)

Contractor Campus is not affiliated to any testing company or government agency. We are an independent school and bookstore providing exam prep services and books to contractors.

Includes the installation, repair, maintenance, and extension of any plumbing system, including drains, waste, sanitary vents, water supply, fixtures, and indirect wastes.

Some counties consider the Master category an actual contractor’s license (used to lawfully engage in contracting) and require taking and passing a business exam. Other counties simply consider the Master category as a step above Journeyman. In cases where the county of your choice does not allow Masters to engage in contracting, you will not be required to take the business exam.
