A UA local is a regional union of plumbers, pipefitters, steamfitters, sprinkler fitters, and HVAC/R service techs chartered by the United Association. Each local covers a geographic area, and its JATC (Joint Apprenticeship & Training Committee) — sometimes a separately branded training center — runs apprentice recruiting, the aptitude test, and the five-year training program.
How to pick yours: find the local whose jurisdiction covers where you live, then check which trades it represents — some metro areas have separate locals for plumbers versus pipefitters versus sprinkler fitters, so make sure you apply to the local that trains the trade you want. If more than one fits, nothing stops you from applying to several.
Application windows vary — a lot. Some locals take applications year-round online; others open a window once a year (or less) for days or weeks, in person only. Missing a window can mean waiting a full year, so click into your local below to see its current status and sign up for a free email alert the moment it opens. Most locals test applicants with the GAN aptitude battery and rank them by score — the higher you score, the sooner you get called.
