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.
