We don't claim to know what's on the UA Local 393 test beyond what they've published themselves. This page documents what we found on their public website. Always verify directly with your JATC.
UA Local 393 does not publicly describe their aptitude test format on their website at the time of our research. Applicants should verify directly at https://ualocal393.org/.

Research notes: Local 393 offloads all apprenticeship application content to the Loyd E. Williams Pipe Trades Training Center (pttc.edu); neither site publicly describes the aptitude test or recommends study materials.
Our study library covers the skill areas UA aptitude tests commonly assess — Reading Comprehension, Figure Visualization, Mechanical Abilities, and Math — with worked examples and practice drills built for pencil-and-paper, no-calculator conditions. We don't claim our library perfectly matches UA Local 393's specific format. What we can say: if your test covers any of the core skill areas, we've got material on it.
