Free, plain-English guides to the IBEW/NJATC electrical apprenticeship aptitude test. The exam runs 97 minutes across two sections — algebra and functions, then reading comprehension — and scores you on a 1–9 band where a 4 or higher unlocks the interview.

Start with the test overview, drill the section you're weakest on, then work through the application and interview prep. Every guide is free and updated for 2026. When you're ready to run the real thing, take the free timed practice test.
