If you want a trade career that’s steady and widely needed, plumbing is one of the best options in New Jersey. The first step is getting the right training. Choosing the right school will set you up with the skills you need and prepare you for licensing.
Here’s what you need to know before you register for a program.
Plumbing license requirements in New Jersey
In New Jersey, plumbers must be licensed by the New Jersey State Board of Examiners of Master Plumbers.
State rule: You cannot perform plumbing work for the public in New Jersey without holding a state-issued license or working under a licensed master plumber.
The state requires you to complete one of the following before applying for the licensing exam:
Four years of work as an apprentice under a licensed master plumber and one year as a journeyman
Four years in a New Jersey apprenticeship program approved by the U.S. Department of Labor
Once you finish your training, you’ll need to pass the state exam to become a licensed plumber.
There are two main paths to prepare for your license:
Plumbing trade school - Classroom and lab training focused on piping systems, codes, and safety. Some schools also set you up with apprenticeships.
Apprenticeship program - Paid training on the job under a licensed plumber, often through a union or contractor association.
Many people combine both-starting with a school program to get the basics, then moving into an apprenticeship.
