Frequently Asked Questions
What is tested on the UA Plumbers & Pipefitters Aptitude Test?
The United Association entrance exam assesses applied piping mathematics (45° offsets, drainage slope, volume, fractions), mechanical comprehension (hydrostatic head, pumps, valves, levers), and technical reading/safety comprehension.
Are calculators permitted on the UA exam?
Calculator policies vary by local union, but most UA Locals strictly prohibit calculators or only provide a basic four-function calculator. Candidates must be proficient in manual fraction arithmetic and pipe offset multipliers (1.414).
What is the qualifying passing score?
Most UA Locals require a minimum composite score of 70% to 75% to advance to the Joint Apprenticeship Training Committee (JATC) interview.
