GAN Human Resources Associates administers aptitude tests for more than 50 union apprenticeship programs across the United States, including IBEW electrician, UA plumber and pipefitter, and UBC carpenter programs. The test screens applicants on numerical computation, reading comprehension, mechanical reasoning, and spatial visualization. This free 16-question practice test covers all four areas — using number sequences as a text-friendly substitute for paper folding — so you can see exactly where to focus your preparation.
What is the GAN aptitude test?
The GAN aptitude test is a standardized entrance exam administered by GAN Human Resources Associates on behalf of union Joint Apprenticeship and Training Committees (JATCs) across the United States. GAN HR works with more than 50 apprenticeship programs to screen and rank applicants before they enter a paid union apprenticeship. Your score — combined with an oral interview at most programs — determines your rank on the acceptance list. GAN HR is one of the most widely used third-party testing providers in the union apprenticeship space, alongside NJATC and EEI.
What sections are on the GAN aptitude test?
The GAN aptitude test covers four areas. Numerical Computation tests basic arithmetic — fractions, decimals, percentages, and measurement math — without a calculator. Numerical Reasoning tests applied problem solving: unit conversions, ratios, basic algebra, and word problems that mirror real trade situations. Reading Comprehension presents short technical passages — similar to safety procedures, apprenticeship agreements, or code definitions — followed by multiple-choice questions. Spatial Visualization (paper folding) tests your ability to mentally rotate and fold shapes; since this section requires diagrams, practice tests often substitute number sequence problems that test the same underlying pattern-recognition skill.
How to prepare for the GAN aptitude test
Start with the math sections — they carry the most weight and are the most improvable with targeted practice. Drill fractions and mixed-number arithmetic (adding, subtracting, multiplying), percentage problems, ratios, and two-step algebra equations. No calculator is allowed, so build mental math speed through daily timed drills. For reading comprehension, practice treating each passage as the sole source of truth — answer only what the text says, even if your field experience suggests something different. For mechanical reasoning, review lever and pulley systems, gear ratios, hydraulics, and heat expansion. For sequences, practice recognizing arithmetic, geometric, triangular, and Fibonacci patterns. Take timed practice tests to build pace — finishing all questions matters.
