A: All Journeymen and Contractors are required to have received six (6) hours of continuing education within the preceding thirty-six (36) months of their license expiration. Visit the Plumbing Industry page for a list of approved CEU courses under “Continuing Education”.


Q: If I fail the test when can I take it again?

A: Thirty (30) days after the first failure, and ninety (90) days after subsequent failure(s).


Q: My contractor has not provided me with the hours I have worked for him so I can prove my experience counts towards licensing. What can I do?

A. Send a written request to the contractor. Contact the CIB if the contractor fails to provide the information after written request.


Q: How can I prove my hours of experience when the contractors I have worked for are dead or out of business?

A: You may use tax records or contact your social security office and request a “Work History Report” and submit a copy of those documents with your application.


Q: Is an apprentice application required every year for apprentice work?

A: Yes. In order for apprentice work experience to be counted towards licensing, it must be verifiable through apprentice registration, unless lawfully obtained while exempted.


Q: Does a licensed contractor have to sign off on the apprentice application every year?

A: Yes, the licensed contractor or approved school/training instructor has to sign the application for the apprentice every year.


Q: Does the CIB keep track of the apprentice hours worked yearly?

A: No, the licensed contractor must, and the apprentice should, keep an account of the apprentice hours worked each year.


Q: I need an application / renewal form / I did not get my renewal form.

A: The application is available for download from this website by going to “Forms/Applications” and clicking on the specific form. Forms are also available at the CIB office, or a form can be mailed to you upon request. When a licensee or registrant has a change in address or phone number, notice to the CIB is required.
