Those who decide to join the piping trades enter into a five-year apprenticeship program, where instructors challenge apprentices as they learn about the complexity of their trade. All applicants are treated equal, no matter the race, sex, national origin or religion of an individual.

As a United Association Local 100 apprentice, you will receive classroom instruction and on-the-job training. The apprenticeship’s earn while you learn model allows students to gain knowledge and experience while earning a paycheck that provides them with livable wages and health and retirement benefits.

Apprentices gain industry experience from on-the-job training as they work side-by-side with journeymen for a contractor affiliated with UA Local 100. This experience prepares apprentices to have a successful career as a UA journeyman.

Besides working for a UA contractor, apprentices receive general industry classroom instruction through core classes in science, mathematics and mechanical drafting.

The UA Local 100 JATC apprenticeship program has been assessed by the American Council on Education, as well as other organizations and colleges, so apprentices can receive free credits toward an associate of science or an associate of arts degree while becoming a journeyman.
