To qualify as a journeyman, one must have five years of experience in plumbing, have a bachelor’s degree in a field like mechanical engineering or have completed an approved apprenticeship program.

To qualify as a master plumber, you need to have four years as a licensed journeyman, three of them working for a master plumber or working in a supervisory capacity.

Both licenses also require passing an exam and must be renewed yearly. Journeymen and master plumbers must complete four hours of continuing education per year. Applications, exams and licenses all carry a fee of $100-160 each.

Most aspiring plumbers start with an apprenticeship. Your apprenticeship is four to five years long, involves classroom education and paid, on-the-job training supervised by journeymen and masters. Apprenticeships must be formally registered and are open to people with a high school diploma or General Equivalency certificates. The state government offers a website with an up-to-date directory of employers who sponsor apprentices.

Plumbing Schools in Montana

There are only two courses that Montana’s Board of Plumbers accepts toward your apprenticeship experience requirement:

  • Montana State University’s College of Technical Sciences, located in Havre, Montana State University, offers a two year associate’s degree.

  • North Dakota’s State College of Science also offers an associate’s degree in plumbing. This can be completed in one year and covers all plumbing basics as well as plumbing network design and drafting.

Many Colleges might offer financial aid to those who qualify. Contact the financial office at the institution you are interested in for more information.

Working as an Apprentice Plumber in Montana

Apprenticeship is a common path to becoming a plumber. An apprenticeship is a training opportunity that also provides a salary. You work with a master plumber, either in a union or non-union setting, earning an income and learning the job skills.

In an apprenticeship in Minnesota, you’ll learn the basics of installing, maintaining and repairing plumbing systems. Once you have enough hours of training, you can apply to become a licensed journeyman plumber, which leads to becoming a master plumber.

The state of Minnesota does not have a prescribed process for becoming a plumber, nor does it require that you become licensed. Unlicensed plumbers must still follow state guidelines, register with the Department of Labor and Industry, and work under the supervision of a licensed plumber.

Whether you choose to become licensed or not, your career as a plumber begins with training, and an apprenticeship is the best way to do it. The Department of Labor and Industry has a search tool to help you find a position as an apprentice.

You can also go directly to unions to apply for their apprenticeship programs. Examples include Plumbers Local 34 in Saint Paul and Plumbers Local 15 in Minneapolis. Contact the Minnesota Pipe Trades Association for access to opportunities through the state’s Joint Apprenticeship and Training Committee.

Many apprenticeship programs will take applicants right out of high school, but an alternative is to start with plumbing courses at a community college. St. Cloud Technical and Community College offers a diploma and associate degree in plumbing.

Montana Plumbing License Requirements

Upon your completion of apprenticeship you’ll receive a certificate. This, along with an affidavit from colleagues as to your experience, a license fee and an exam passed with a score of at least 70 percent, is required to get your journeyman’s license. The exam is administered by the International Association of Plumbing and Mechanical Officials and can be taken in person and online. The license must be renewed annually.

The master’s license requires a similar affidavit for four years of journeyman experience and a 70 percent or higher score on the master’s license exam, and it must be renewed annually.
