The 6-Step Path to Licensed Plumber

1

High School or GED + Pre-Apprenticeship

Age 16-18

Focus on maths and physics. Take any available shop or vocational classes. Pre-apprenticeship programs at community colleges and vo-tech schools can count toward apprenticeship hours in some states and make JATC applications more competitive. Some school districts have plumbing pathway programs that provide early hours.

2

Choose Union or Non-Union Apprenticeship

Age 18+

Apply to a UA JATC (union) or to a non-union plumbing contractor. Union JATCs are competitive in major metros, with acceptance rates as low as 10 to 20 percent in some markets. The JATC application typically requires: proof of HS diploma or GED, a basic math aptitude test, a mechanical aptitude test, and work references. Non-union contractors hire apprentices more readily; pay and benefits may be lower but you start working faster.

3

Complete the Apprenticeship (4-5 Years)

Years 1-5

8,000 to 10,000 hours of on-the-job training combined with 200 or more hours of classroom instruction per year. You work full-time and attend classes evenings or weekends. Pay starts at 50 to 60 percent of journeyman rate and increases each year. By Year 4, most apprentices earn 85 to 90 percent of journeyman rate. Union apprenticeships are free; non-union programs may charge $1,000 to $5,000 in materials and classroom fees.

4

Pass the Journeyman Plumber Exam

After Year 4-5

After completing your apprenticeship hours, apply to your state licensing board to sit the journeyman exam. Requirements and exam format vary by state. Most exams cover the plumbing code (UPC or IPC), pipe sizing, fixture installation, and safety. Fees are $50 to $300. Pass rates are typically 60 to 80 percent for first-time takers. Once licensed, you can work independently and pull permits in your own name in most states.

5

Build Experience as a Journeyman (2-5 Years)

Years 5-10

This is when you develop your specialisation. Commercial journeymen command higher pay; industrial pipefitting pays even more. Use this phase to study for the master exam, build relationships with contractors and customers, and save toward starting your own business. Many journeymen also pick up specialty certifications (medical gas, backflow, gas fitting) that add $2 to $8 per hour to their rate.

6

Master Plumber License (If You Want It)

Year 7-10+

After satisfying your state's journeyman experience requirement (2 to 5 years depending on state), apply to take the master exam. The master exam is harder, covering advanced code, system design, and business law. Pass rates are 50 to 70 percent. Once licensed, you can start your own plumbing business. The master license is required to operate a plumbing company in most states.

A 4-year college graduate also exits with an average of $37,338 in student loan debt (College Board 2024). A union plumbing apprentice exits with zero debt and 4 years of paid experience. The debt drag takes 10+ years to overcome for many graduates.
