Adult Education Classroom

One day of class is all you need to review the five reference books

we cover hundreds of sample test questions, teaching you to use your code books and apply the simple test-taking techniques

The pace is fast but so is your P-1 exam:

  • 158 technical questions in four hours
  • 50 business questions in 1.5 hours

In North Carolina, you submit an application to the Plumbing, Heating, Fuel Gas & Fire Sprinkler Board of Examiners before you take a license exam.

For more information about NC Contractor Licensing and the field experience required to qualify, click on the link to download the license application form for the NC P-1 Plumbing license, or visit the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors website.

The Application Process:

• Submit your license application to the NC Board of Examiners and enroll for your plumbing exam prep course date, click here to open and print the Plumbing License Application.

• The State Board’s Application approval process typically takes approximately 4-6 weeks; notification is sent via US mail and email

• Once approved, you’ll have approximately 90 days to take your NC Business and NC Plumbing Technical exams (both exams are scheduled for the same day, at a PSI Testing Center near you)

I attended your class last Friday and tested the following Saturday.  I was able to pass my P-1 on my first attempt because of your strategy.

I also believe I was able to quickly answer the isometric drawing questions after you showed how a common sense approach was possible that kept me out of all the tables.  Thanks for all your help, I will be recommending your services.

Lucas Beaver, Beaver Contracting LLC


I would like to thank you for all the help your class gave me in preparing for my plumbing test.

I passed, the first shot, with flying colors!  I walked out of the testing center 100 percent sure that I had passed.  All the other classes I took for the test, didn’t hold a candle to the way you broke all the books down.  I will strongly suggest your class to up and coming plumbers.

This is the most important step I have taken in my life that will guarantee a good future for myself and my family, and without your class it would have taken me a lot longer to get to this point.

Thank you very much for your help in achieving this goal.

‘Just wanted to let you know that I passed my P-1 exam yesterday. Thank you for your study guide that was exactly on point. The technique you teach is the way to go for sure.

I would recommend it to anyone.  I have used your class now to take 4 exams (H-3, H-2, H-1, and P-1) and have passed them all the first time.

Probably will take your class for the electrical exam coming up in the future. Thanks again for the help!
