Apprenticeships: How Paid On-the-Job Training Works

What a registered apprenticeship is, how pay and training work, which careers offer apprenticeships, how to find and apply to one and how to prepare for the entrance test.

Quick answer

An apprenticeship is a paid job that includes structured on-the-job training plus related classroom instruction, usually lasting one to five years. Registered apprenticeships lead to a nationally recognized credential. You earn wages from day one, often with scheduled raises as your skills grow, and typically finish with little or no student debt.

How apprenticeships work

  • You’re hired and paid. Apprentices are employees, earning wages from the start.
  • You learn on the job. You work under experienced journeyworkers, building skills through real work.
  • You take related classes. Classroom or online instruction covers theory, codes, math and safety, often a set number of hours per year.
  • Your pay grows with your skills. Many programs increase pay at set milestones.
  • You earn a credential. Completing a registered apprenticeship earns a nationally recognized certificate of completion.

Which careers offer apprenticeships?

Traditional trades are the best known: electricians, plumbers, carpenters, HVAC technicians, lineworkers, heavy equipment operators, glaziers and mechanical insulators. Apprenticeships are expanding into IT, cybersecurity, healthcare, manufacturing and logistics too. See jobs with paid on-the-job training.

Types of programs

  • Union (joint) apprenticeships run by unions and employer associations.
  • Non-union (merit shop) programs run by contractor associations or individual employers.
  • Employer programs in companies, hospitals and utilities.
  • Pre-apprenticeships that prepare you to qualify and apply.

How to find one

  • Search Apprenticeship.gov, the U.S. Department of Labor’s apprenticeship finder.
  • Contact local union training centers and contractor associations.
  • Visit your local American Job Center or community college.
  • Ask employers directly. Some hire apprentices without advertising widely.

How to prepare

  • Math: Many entrance tests include algebra and basic math. Review before you test.
  • Reading comprehension: Practice reading technical material.
  • Requirements: Most programs require a high school diploma or GED, a minimum age (often 18), a driver’s license and the ability to pass a drug test.
  • Show commitment: Safety training such as OSHA 10, related work experience and reliable transportation help.

Is an apprenticeship right for you?

It’s a great fit if you want to earn while you learn, prefer hands-on work and can commit to a multi-year program. The trade-off: you start at lower apprentice wages and must balance work with classes.
