STSC practice questions - frequently asked questions

Plain answers about how STSC Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real STSC exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The STSC exam spans 6 domains: Construction Health Hazards (14% of the exam); Construction Safety Hazards (25% of the exam); Roles and Responsibilities (14% of the exam); Leadership and Communication (10% of the exam); Training Requirements and Methods (12% of the exam); Safety Management Systems and Programs (25% of the exam). Every practice question on this site is tagged to one of these domains.

The domains are not weighted equally on the exam. By share of the marks: Construction Safety Hazards 25%; Safety Management Systems and Programs 25%; Construction Health Hazards 14%; Roles and Responsibilities 14%; Training Requirements and Methods 12%; Leadership and Communication 10%.

The STSC exam has 100 questions and is completed in 2 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
