NCCER Core Curriculum — what's actually tested on the written exam?

My apprenticeship program requires passing the NCCER Core written test and I want to know what to actually expect. I've gone through most of the Core Curriculum modules but some of it feels like it wouldn't be on an exam — like a lot of the tool identification picture content. Does the written portion focus heavily on safety and math or is it more spread across all the modules?

I've got about 2 weeks before the test date. The program coordinator said it's 50 questions and you need a 70% to pass, but didn't give me much beyond that. I work construction already so the hands-on material is no problem — it's the written theory portion I'm less confident about. How long did people actually spend on the study material?

Also wondering if the NCCER test is the same across all crafts or if it varies. I'm going into electrical, so I'm curious whether some questions are electrical-specific even at the Core level or if that's all in the later modules.

Two weeks is plenty of time. I passed with an 82% after about a week of studying maybe an hour a night. The math section is basic — fractions, area calculations, unit conversions. Nothing you wouldn't use on a job site already.

Core Curriculum is the same regardless of craft — it's all general construction fundamentals. The electrical-specific content starts when you hit Module 1 of the electrical track. Core covers safety, hand tools, power tools, basic math, and blueprint reading.

The safety and OSHA sections are heavily tested — probably 30–40% of questions from my experience. Know your PPE requirements, fall protection thresholds (6 feet in construction), and lockout/tagout steps in order. That content is straightforward points if you study it.

Coming back to this thread — just passed my NCCER yesterday. Everything about the nccer practice test section is accurate. For anyone still studying, the free nccer basic safety test 1 was the closest thing to the real exam I found.

Failed first attempt, came back to this thread. The consensus on nccer practice test being the make-or-break area is right. Focusing almost exclusively on applied questions this time around.
