Built by a federally recognized pre-apprenticeship instructor who has helped hundreds of applicants get into building-trades unions. Getting into a union plumbing, pipefitting, steamfitting, HVAC-R or sprinkler-fitting apprenticeship starts with one test: the aptitude battery administered by GAN Human Resources on behalf of United Association (UA) locals across the country. Most locals rank every qualified applicant by score and fill their classes from the top of the list down. Passing isn't the goal. Out-scoring the list is. WHAT'S ON THE TEST About 140 questions in roughly two hours, across six timed sections — Reading Comprehension, Numerical Computation (fractions, decimals, percentages), Numerical Reasoning (number series), Problem Solving (word problems), Paper Folding (spatial visualization), and Mechanical Comprehension. No calculator. Around 70% is a common minimum to qualify, and your score becomes your ranking number. HOW PIPEPREP AI GETS YOU RANKED HIGHER • 10 FULL-LENGTH PRACTICE BATTERIES — six timed sections mirroring the real format, no calculator • 1,500+ PRACTICE QUESTIONS with explanations that teach the method — and name the trap that catches everyone else • SCORE REPORT BUILT FOR RANKING — overall accuracy, a rank band, all six sections scored instantly • SECTION DRILLS & MISSED-QUESTION REVIEW — attack your weakest section until it isn't • SPEED SPRINTS — 60-second no-calculator roes, and number series • PAPER-FOLDING TUTORIAL — the section everyone fears, taught visually: fold, punch, unfold • PIPER, YOUR AI TUTOR — ask anything by text or voice: fractions, gear ratios, pacing, or what the interview panel scores • ORAL INTERVIEW PREP — 48 panel questions with model answers, plus AI mock interviews scored like real panels • 220 UA LOCALS ACROSS 48 STATES AND DC — plr, HVAC-R and sprinkler locals, each with its hall, JATC training center, phone, and how to apply • APPLICATION WINDOW TRACKER — set your local and the study plan paces itself to that deadline FIELD TOOLS YOU KEEP AFTER TEST DAY — FREE No subscription required: Pipe Offset Calculator, Takeout & Cut Length, Grade & Slope, Pipe Volume & Test Fill, DFU Drain Sizer, Gas Line Sizer, Hanger Spacing,er Supply Demand, Fraction Calculator, Time & Labor Calculator, Hours Tracker, and an offline Cheat Sheet. COMMON QUESTIONS Can I use a calculator? No — and that's exac Every question here is built to be solved by hand. What's the passing score? Roughly 70% at most locals, but qualifying only gets you on the list — seats fill from the top score down. Do all locals use the same test? Most use the GAN battery; some use other assessments. Confirm with your local. What's the hardest section? Usually Paper Folding and the time pressure — both trained here. When is my local accepting applications? Win three weeks, once every year or two. Setyours and the app paces you to it. Do I need experience? No. Most UA apprenticeships ask for 18+, a high school diploma or GED, and the aptitude test. Does it pay? Yes — UA apprentices earn while to hours worked and school completed. Askyour local for its scale. Your first full-length battery is free. Go earn your spot. SUBSCRIPTION 7-day free trial — full unlimited access. Pro Monthly: $14.99/month. Pro Annual: $79.99/year. Auto-renews unless cancelled at least 24 hours before the renewal date.
