What is the Pipefitter Test?

The pipefitter is a screening test used by local unions in the U.S and Canada to screen candidates who want to be accepted to a union apprentice program.

The screening test used by unions in the US is different from those administered to apprenticeship applicants in Canada.

These programs are designed to help candidates become familiar with safety codes and regulations of the field

As part of the apprenticeship program, apprentices study mathematics, applied physics, and chemistry. In most cases, apprentices enter directly into a program, but others may begin as helpers.
