Construction Basics Practice Test
Twenty-five original questions on the fundamentals of working on a construction site: personal protective equipment, recognizing the hazards that cause most serious injuries, reading a set of plans, the measurement and math the work actually requires, common materials and tools, and the communication habits that keep a crew safe and productive. Every answer is explained.
For information and self-assessment only, to help you prepare. Always refer to the official certifying body's own materials and content outline as the source of record.
Official body: OSHA Training Institute / NCCER ↗ — OSHA 10 and 30 outreach cards are the standard site-safety credentials; NCCER Core is the standard entry curriculum

Frequently asked questions
Is this an OSHA card or a certification test?
No. These are original practice questions written to cover the ground an introductory construction course covers. An OSHA 10 or 30 card comes from an authorized trainer and cannot be earned online through a quiz like this one. Use these questions to check your understanding, then get the real training through a recognized provider.
What score means I am ready?
Seventy percent is the threshold used here, but on a construction site the safety and hazard recognition sections are the ones to be strongest in. A high total built on a weak hazard section is the wrong shape of result. The breakdown by topic is there so you can see which section carried you.
How long does it take and when should I take it?
About twenty-five minutes at a steady pace. Take it before a course or an interview rather than after, because its value is in showing you what you do not know yet. Retake it a few days later instead of immediately, since spacing the attempts is what makes the material stick.
Do the safety rules in these questions apply everywhere?
The underlying hazards do, but the specific numbers do not. Trigger heights for fall protection, trench depths requiring protective systems, and approach distances to power lines are set by the regulator where you work and change between countries and states. Learn the concept here, then follow the rule and the site plan that actually govern your job.
