Getting Started
You're preparing for a UA Plumbing & Pipefitting pre-apprenticeship aptitude test. This site was built by someone who passed it on his first attempt. Here's how to use it.
It's the aptitude test your local UA JATC uses to decide whether you enter their apprenticeship program — and where you rank on the eligibility list. Higher score = earlier call.
UA aptitude tests vary by local in format, length, and topic mix. The skill areas below are what most of them commonly assess. Always verify the specifics with your local JATC — and check our UA Locals research to see what individual locals publish.

Skill Areas
Our library covers the skill areas UA aptitude tests commonly assess. Your local may test a subset, or include topics we're still adding — always confirm with your JATC.
Long
Plan for Multiple Hours
Plan for a long test day — many UA aptitude tests run a half-day, and your local's exam-day instructions will give you the exact length. Mental stamina matters as much as knowledge — you can't cram that on test day.
Per-Section
Pass Every Section
Most locals set a per-section minimum — miss even one and you retake the whole test with a long wait. Thresholds vary by local (our founder's local required 70% on each section); confirm yours before test day.
Pencil
Paper Only
No calculator, no phone, no scratch paper you bring in. Testing materials are provided. Everything — including all math — is done by hand.
Rank
Score = Priority
Your score determines your position on the eligibility list. A 90% gets called for an apprenticeship slot long before a 75%.

Official Study Guides
Most UA locals we've researched don't publish a study guide. The apprenticeship our founder tested into simply says, “We do not offer a study guide.” That's why this site exists.
UA Test Prep follows a learn-then-test approach. Study guides teach you the concepts and strategies. Practice tests measure whether you've actually learned them.
Step 1
Each skill area has a dedicated study guide with strategies, worked examples, and interactive demonstrations. Start here before you touch a practice test. Understanding the format is worth real points by itself.
Step 2
Once you understand the concepts, test yourself under realistic conditions. Timed. Pencil and paper. No calculator. Every question includes a detailed explanation so you learn from your mistakes, not just your score.
Each skill area has its own study guide and practice bank. Your local may test all of these, a subset, or something we haven't covered yet — email us if so and we'll add it.
Retention-style reading: you read a passage, it's taken away, and you answer from memory. Tests how much you can hold, not how fast you can skim.
Mental paper-folding, shape rotation, and pattern matching. Pure spatial reasoning — no math, but you have to see it in your head.
Gears, pulleys, levers, fluid behavior, basic physics. If gear A turns clockwise, which way does gear D turn? That kind of thing.
Arithmetic, fractions, decimals, percentages, perimeter and area, simple interest — all by hand, no calculator. The section people underestimate.
Reading charts, tables, schedules, and schematics to pull out a specific value. Some locals (WorkKeys-format tests) score this as its own section.
Work orders, safety notices, policy memos, equipment manuals. The document stays in front of you — the trap is trigger words and conditions.
Math word problems with real workplace context — pipe lengths, tank volumes, crew time, material cost. Same underlying math, translated into scenarios.
You don't need to study 8 hours a day. Consistent, focused sessions — 45 minutes to 1 hour daily — will get you there. Here's a proven structure.
