Thinking about becoming a plumber but worried you’ll need years of college? You’re not alone. Many people assume skilled trades like plumbing require expensive degrees—but the truth is far more practical and affordable. In this guide, we’ll break down exactly how much school you need to be a plumber, including timelines, costs, and real-world steps to get licensed and earning quickly.
Do You Need a College Degree to Become a Plumber?
Short answer: No. Unlike careers in medicine or engineering, plumbing doesn’t require a four-year college degree. In fact, most plumbers never step foot in a traditional university.
According to the U.S. Bureau of Labor Statistics (BLS), the typical entry path involves a high school diploma or GED, followed by an apprenticeship—often combined with technical coursework. This route prioritizes hands-on experience over academic theory, which is exactly what employers and clients value most.
“Plumbing is a skill-based trade. What matters isn’t how many books you’ve read—it’s whether you can fix a leaky pipe at 2 a.m.,” says Mike Rodriguez, a master plumber with over 20 years of experience in Texas.
So while formal education helps, it’s not the kind you might expect.
What Kind of Schooling Is Required?
While no college degree is needed, structured training is essential. Here’s the standard educational path:
1. High School Diploma or GED
This is the baseline. Courses in math (especially geometry and algebra), science, and shop class provide foundational skills. Understanding measurements, pressure systems, and basic physics makes learning plumbing easier.
2. Vocational or Trade School (Optional but Helpful)
Many aspiring plumbers attend a technical or trade school for 6 months to 2 years. These programs cover:
- Blueprint reading
- Local plumbing codes
- Pipefitting and soldering
- Safety protocols
Average cost: $1,000–$15,000, depending on location and program length. Community colleges often offer the most affordable options.
💡 Pro Tip: Some trade schools partner with unions or contractors, giving students direct access to apprenticeships upon graduation.
3. Apprenticeship (The Real Classroom)
This is where 90% of your learning happens. A plumbing apprenticeship typically lasts 4 to 5 years and includes:
- 2,000 hours per year of paid on-the-job training
- 144–200 hours per year of classroom instruction
You earn while you learn—starting at $15–$20/hour, with wages increasing as you gain skills.
Apprenticeships are offered through:
- Unions (e.g., United Association)
- Non-union contractors
- State or local plumbing boards
Find registered programs via the U.S. Department of Labor’s Apprenticeship Finder.
How Long Does It Take to Become a Licensed Plumber?
Timeline varies by state, but here’s a general breakdown:
| Stage | Duration | Key Milestones |
|---|---|---|
| High School / GED | 0–4 years | Complete basic education |
| Trade School (optional) | 6 mos – 2 yrs | Learn fundamentals |
| Apprenticeship | 4–5 years | Work + classroom training |
| Journeyman License | After apprenticeship | Pass state exam |
| Master Plumber (optional) | +2–5 years exp. | Advanced certification |
Most plumbers become fully licensed journeymen in 4–5 years—faster than many bachelor’s degrees—and start earning solid income long before that.
According to BLS data (2025), the median annual wage for plumbers is $60,090, with top earners making over $100,000—especially in states like Alaska, Illinois, and New York.
State Licensing Requirements: What You Must Know
Licensing rules differ by state, but nearly all require:
- Completion of an approved apprenticeship
- Passing a written exam on plumbing codes and safety
- Proof of work experience
For example:
- California: Requires 4 years of experience + exam
- Texas: 48 months of field experience + jurisprudence exam
- New York: Varies by county; NYC requires 5 years
Always check your state’s plumbing board website for exact rules. Skipping licensing isn’t just risky—it’s illegal in most places and can result in fines or shutdowns.
📌 Note: Plumbing codes are based on national standards like the Uniform Plumbing Code (UPC) or International Plumbing Code (IPC), which are updated regularly. Staying current is part of the job.

FAQ Section
Q1: Can I become a plumber without any formal schooling?
A: Technically, yes—if you secure an apprenticeship directly. However, most programs require at least a high school diploma or GED. Basic math and reading skills are non-negotiable for interpreting blueprints and codes.
Q2: How much does plumbing school cost?
A: Trade school programs range from $1,000 (community college) to $15,000 (private institutions). Compare this to the average $35,000+ annual cost of a four-year college—plumbing offers massive ROI.
Q3: Is online plumbing school valid?
A: Partially. While some classroom hours can be completed online, hands-on training is mandatory. Avoid fully online “certification” mills—they won’t qualify you for licensing.
Q4: How hard is the plumbing license exam?
A: It’s challenging but passable with preparation. Exams test knowledge of local codes, math, and system design. Most states publish study guides and practice tests. First-time pass rates average 65–75%.
Q5: Can I start my own plumbing business after licensing?
A: Yes! Once you’re a licensed journeyman (and later a master plumber in some states), you can operate independently. Many plumbers launch successful businesses within 5–10 years of starting their careers.
Q6: Are there age limits to becoming a plumber?
A: No. Apprenticeships accept adults of all ages. In fact, career changers over 30 make up nearly 22% of new plumbing apprentices (DOL, 2025).
Conclusion
So, how much school do you need to be a plumber? Far less than you think—and far more rewarding than most expect. With minimal upfront cost, strong earning potential, and high demand (the BLS projects 5% job growth through 2034), plumbing is a smart, future-proof career choice.
You don’t need a mountain of debt or a decade in classrooms. You need grit, reliability, and a willingness to learn. The pipes aren’t going anywhere—and neither will the need for skilled professionals who can fix them.
