You sat the battery, you got the letter, you passed. It is a real milestone and it is worth about a day of celebrating. Then it is worth understanding what it actually bought you, because a lot of applicants stop preparing here and that is exactly the wrong moment to stop.
Passing does not mean you are in. It means you are still in the running.
At most UA locals, passing the aptitude battery makes you eligible for an interview with the JATC panel — typically several people, working from a standardised scoring sheet rather than an open conversation. This is not a formality and it is not a chat. It is the second half of your score.
The thing worth internalising: at many locals the interview carries at least as much weight as the test, and sometimes more. A strong test score and a weak interview lands below a solid-both candidate. Applicants routinely prepare for months for the test and for twenty minutes for the interview, which is the wrong ratio by a wide margin.
We cover what the panel is actually scoring in a separate piece, and there is a question bank to practise against.
Your aptitude score and interview score combine into a single ranking. Everyone who made it that far goes onto a hiring list in rank order, and apprentices are called from the top down as the local needs them.
Three consequences people miss:
This is the part nobody warns you about. Between the list being published and your phone ringing there can be weeks, or there can be most of a year. It depends on your rank and on how much work the local has, and neither of those is something you can influence after the fact.
When the call comes it usually moves fast. Expect some combination of a drug screen, a physical, proof of the documents you claimed on the application, and paperwork that formally indentures you to the program. From there it is roughly five years of paid work for signatory contractors plus scheduled related training, with wage progression tied to hours and coursework rather than the calendar.
We walk through that whole timeline in how long it takes to become a union plumber.
Retest policies vary by local — many publish a required waiting period before you can sit the battery again, often tied to the next application window rather than a fixed number of months. Check your local’s instructions rather than a forum.
The more useful question is what to fix. A failed battery is almost never a general intelligence problem; it is usually one section running out of time. Sitting a full-length timed practice test and looking at the per-section breakdown tells you which one in about two hours.
At most locals: an interview with the JATC panel, then a combined score that places you on a ranked hiring list. Apprentices are called off that list in order as the local needs them, which can be weeks or many months. Lists expire — commonly after one to two years — and if you are not called before yours does, you reapply.
No. Passing makes you eligible to continue. The aptitude score at most UA locals is not pass/fail alone — it feeds a ranking, and the interview usually carries at least as much weight in where you land on the list.
It depends entirely on your rank and on how much work the local has. Some applicants are called within weeks of the list being published; others sit on it until it expires. Locals publish intake sizes rarely, so ask directly rather than guessing from forum posts.
You reapply at the next window, and in most cases you retest. Staying reachable — a working phone number and a current address on file with the JATC — matters, because locals do move down the list when someone cannot be reached.
