Do You Need a High School Diploma to Be a Plumber?

Thinking about becoming a plumber but worried your lack of a high school diploma might hold you back? You’re not alone. Many aspiring tradespeople ask, “Do you need a high school diploma to be a plumber?” The good news? In most cases, you don’t—but having one (or its equivalent) can open more doors. Let’s break down exactly what’s required, what’s recommended, and how you can launch a successful plumbing career regardless of your educational background.

What Are the Basic Requirements to Become a Plumber?

While plumbing is a skilled trade that demands technical know-how, problem-solving ability, and physical stamina, formal education requirements are surprisingly flexible.

Minimum Educational Threshold

• High school diploma or GED: Most plumbing apprenticeship programs and trade schools prefer applicants to have a high school diploma or GED, but it’s not always mandatory.
• Age requirement: You typically need to be at least 16–18 years old, depending on your state.
• Legal authorization: You must be legally allowed to work in the U.S.

According to the U.S. Bureau of Labor Statistics (BLS), the standard path into plumbing begins with an apprenticeship, which usually lasts 4–5 years and combines paid on-the-job training with classroom instruction.

💡 Pro Tip: Even if a program doesn’t require a diploma, lacking one may limit your options. Many unions and reputable contractors use it as a baseline filter.

Can You Become a Plumber Without a High School Diploma?

Yes—but with caveats.

Some independent contractors or small plumbing companies may hire helpers or apprentices without a diploma, especially in rural or underserved areas where skilled labor is in short supply. However, these opportunities are becoming rarer.

Real-World Example

James R., a journeyman plumber in Ohio, started as a helper at 17 without finishing high school. “I learned by watching, asking questions, and doing grunt work,” he says. “But when I tried to join a union apprenticeship at 20, they turned me down because I didn’t have my GED. I got it six months later—and my career took off.”

This illustrates a key point: You might start without a diploma, but advancing often requires one—or at least a GED.

Why a High School Diploma (or GED) Helps—Even If It’s Not Required

While not always a hard requirement, a high school education provides foundational skills crucial for plumbing success:

The National Center for Construction Education and Research (NCCER) notes that apprentices who’ve completed high school are 30% more likely to complete their training programs successfully.

High School Diploma vs. GED: Does It Matter for Plumbers?

In practice? No. Employers and licensing boards treat a GED as equivalent to a high school diploma.

However, some union apprenticeships may give slight preference to diploma holders during competitive application cycles. But once you’re in the field, your skills—not your transcript—determine your success.
