Thinking about a stable, high-demand career in the trades—but not sure where to start? If you’re in or near St. Louis, Missouri, becoming a plumbing apprentice through a Department of Labor Plumbing Apprentice Authorized Contractor is one of the smartest first steps you can take. These registered programs combine paid on-the-job training with classroom instruction, all under the oversight of the U.S. Department of Labor (DoL). Let’s break down exactly how it works, why it matters, and how you can get started—no prior experience required.
What Is a Department of Labor Plumbing Apprentice Authorized Contractor?
A Department of Labor Plumbing Apprentice Authorized Contractor is a licensed plumbing company or organization officially registered with the U.S. Department of Labor’s Office of Apprenticeship. These contractors meet strict federal standards for training, safety, mentorship, and curriculum.
Unlike informal “helper” roles, apprentices in DoL-registered programs earn while they learn—typically starting at 40–50% of a journeyman plumber’s wage, with scheduled pay increases as skills improve. According to the U.S. Bureau of Labor Statistics, plumbers in Missouri earn a median annual wage of $57,230, with strong job growth projected through 2032.
These programs usually last 4–5 years, requiring around 8,000 hours of hands-on work and 500–1,000 hours of classroom instruction.
💡 Pro Tip: Only DoL-registered programs qualify for federal recognition, making your certification valid nationwide—not just in Missouri.
