Journeyman Plumber’s Exam

Most states require journeyman plumbers to be licensed by the state or local government to work as a plumber. Part of the licensing process consists of an exam for certification. This ensures that each applicant meets the states standards on public safety and consumer protection while working.


Eligibility for certification as a journeyman plumber is typically different depending on which state or local government you are applying to work in. You will first need to know whether such government regulates plumbers in the traditional trade language or if it is regulated in terms of contractors, as this will make all the difference on what qualifies you for this career.

Does It Cost Anything?

The exam usually does require a fee to take. This will vary depending on the state or licensing agency being used.

Required Experience

Most states and municipalities require applicants to prove that they have worked as an apprentice under the supervision of a licensed journeyman or master plumber for a certain amount of time. This time period will differ slightly; however, most require at least one year.

Some states or licensing agencies may require certain forms to be filled out by the supervising plumber to prove this. Other states may force applicants to complete an accredited apprenticeship program. This must be done before they apply for their license.

In most cases, the experience required for licensure can be met by either education and/or by working experience. This means that if a candidate has completed a specific training program their amount of time required for experience may be reduced.

What The Exam Covers?

The exams will vary depending on the state or municipality offering the licensure. However, most include around 100 multiple choice and true/false questions. These are typically situation based. In this type of question, you will be given some facts and answer the question based on those facts.

Exams are usually taken at a testing company location a few times a year. The test may be taken using a computer or may use paper and pencil, depending on your available testing sites.

They typically only test over trade knowledge and skills such as the following:

  • Storm drainage systems
  • Interceptors and traps
  • General knowledge and regulations
  • Venting
  • Water supply systems
  • Isometric analysis
  • Joints and connections
  • Hangers and supports
  • Backflow prevention
  • Plumbing fixtures, including water heaters
  • Septic and sewer
  • Drainage waste

However, some states or local areas may ask a few questions about the business and law aspects of the job. This is not typical unless the area regulates journeyman plumbers in terms of contractors.

It is not a bad idea to be prepared for these types of questions anyways, in the case that there are questions about the following subjects:

  • Permitting
  • Insurance and bonding
  • Bidding process
  • Business management
  • Contracting
  • Worker safety
  • Environmental laws
  • Accounting and tax matters
  • Labor laws

Depending on the length of the test you will be given anywhere from two to five hours to complete it.

To get an exact idea of a journeyman plumbers’ exam in your area will be like you will need to contact or seek out your state agency that is giving the exam or the testing company being used for such testing.

Journeyman Plumber’s Study Guide – Sabrina

I am finding this study guide to be a very valuable asset for me. Not only does it give you great test taking advice on how to select the proper answer when the trick questions pop up but it also has a section full of content to remember for the test. It's like having a code book that isn't boring and hard to read! Well worth the money!

Journeyman Plumber’s Study Guide – Peter

My impression at first was that I knew everything there was to know about plumbing and there would be very little I "highlight" because I know all aspects of plumbing. I am about 20% through the study guide so far and I'm astonished at how much I don't quite know. I 'm very happy with the guide so far because it's easy to read and understand and I plan on kicking butt when it comes to exam time as I feel the guide so far has everything I need to successfully pass. I especially like how there are test taking strategies and how to overcome anxiety when taking a test. This guide has way more than just the information I purchased.
