If you want a stable, hands-on career, plumbing is one of the most reliable trades you can enter. Good plumbers will stay in demand, and the work can lead to your own business in time. The first step is getting the right education and training.
Here's what you need to know before choosing a plumbing school or program.
Plumbers install, maintain, and repair piping systems that carry water, waste, gas, and more. The work covers homes, businesses, and industrial sites. Training will also teach you how to read blueprints, follow building codes, and work safely.
State law may require you to complete both classroom training and supervised on-the-job experience before you can work independently. Always check your state's licensing board.
Every state has its own licensing process. In most cases, the path looks like this:
Enroll in a plumbing trade school or apprenticeship.
This gives you both classroom instruction and hands-on practice.
Complete the required hours of training.
States often set a minimum number of educational and job-site hours.
Pass an exam.
This may include a written test and a practical skills assessment.
Apply for your license.
Your state board will need proof of your completed training and test results.
Keep up with continuing education.
Some states require ongoing classes to maintain your license.
Plumbing schools and programs generally fall into three categories:
Certificate and Diploma Programs
Shorter programs (often a few months to a year) focused on essential skills.
Associate Degree Programs
Two-year programs with broader coursework, sometimes including business skills.
Apprenticeships
Often run by unions or contractors, apprenticeships combine paid work with training and can last 4-5 years.
Here's a quick overview:
Program Type | Typical Length | Includes On-the-Job Training? |
---|---|---|
Certificate/Diploma | 6-12 months | Usually basic labs only |
Associate Degree | 2 years | Some internships/labs |
Apprenticeship | 4-5 years | Yes, paid supervised work |
The "best" school depends on your location, career goals, and schedule. Consider these recognized options:
Local Community Colleges
Many offer certified plumbing technology programs with evening or weekend classes.
UA Local Union Training Centers
The United Association offers structured apprenticeship programs with strong job placement.
PHCC (Plumbing-Heating-Cooling Contractors) Educational Foundation

NCCER-Accredited Training Centers

State-Approved Apprenticeship Programs
Check your state's department of labor or licensing board for registered options.
Tip: If you want to work as a licensed plumber in your state, the school or program must be recognized by your state licensing authority.
When comparing schools, ask:
Is the program state-approved?
Without approval, your training might not count toward licensing.
Does it include hands-on training?
Skills developed in labs or job sites matter more than theory alone.
Are instructors licensed plumbers?
Experienced teachers with field knowledge give better practical advice.
What's the job placement rate?
Strong school-to-work pipelines mean faster entry into the trade.
What's the schedule and cost?
Make sure you can afford tuition and handle the class times.
Licensing rules vary. Some states require thousands of hours of supervised work. Others have tiered licenses like apprentice, journeyman, and master plumber.
Example: The Texas State Board of Plumbing Examiners requires a minimum of 8,000 hours of experience under a licensed plumber before you can take the journeyman license exam1.
Always verify requirements with your state plumbing licensing board before enrolling in a program.

Following safety rules protects you and your customers, and it's also legally required.
