33 questions available

The Construction Health and Safety Technician (CHST) Practice Test is a comprehensive assessment tool designed for safety professionals working in the construction industry. This exam evaluates your knowledge and application of three core domains: Construction Hazard Recognition, OSHA Construction Standards, and Safety Planning. It is intended for individuals preparing for the official CHST certification exam administered by the Board of Certified Safety Professionals (BCSP), as well as for current safety technicians, site supervisors, and project managers seeking to validate their expertise. The test covers critical topics such as identifying physical, chemical, and ergonomic hazards on construction sites; interpreting and applying OSHA 29 CFR 1926 standards; and developing effective safety plans, including emergency response, site-specific safety programs, and job hazard analyses. By taking this practice test, you will gain a clear understanding of your strengths and weaknesses across these domains, build familiarity with the exam format and question style, and improve your ability to apply safety principles to real-world construction scenarios. This practice test is a vital step toward achieving CHST certification, which demonstrates your commitment to worker safety and your competence in managing construction site risks.

Why This Certification Opens Doors

This practice test matters because construction remains one of the most hazardous industries in the United States, with thousands of fatalities and hundreds of thousands of injuries each year. The CHST credential is recognized by employers as a mark of a safety professional who can proactively identify hazards, ensure compliance with OSHA standards, and implement effective safety plans that prevent incidents before they occur. By mastering the content in this practice test, you are not just preparing for an exam; you are building the practical skills needed to protect workers on active job sites, reduce employer liability, and foster a culture of safety that improves project outcomes. The real-world impact is direct: every hazard you learn to recognize and every standard you learn to apply can prevent a fall, a cave-in, or a toxic exposure. This practice test bridges the gap between theoretical knowledge and life-saving action.

These are the backgrounds the certifying body suggests. Check the vendor's own page for anything it formally requires.

Frequently Asked Questions

How many questions are on the actual CHST exam, and how does this practice test compare?

The actual CHST exam consists of 200 multiple-choice questions, and you have 4 hours to complete it. This practice test contains 33 questions, which is designed to give you a representative sample of the three core domains. While it is not a full-length simulation, it provides a reliable indicator of question style, difficulty, and topic distribution.

What is the passing score for the CHST exam?

The BCSP does not publish a fixed passing score, as it uses a criterion-referenced scoring method based on the difficulty of the specific exam form. However, most candidates aim for a scaled score of 70% or higher. Focus on mastering the content rather than chasing a specific percentage.

Do I need to memorize specific OSHA standard numbers?

Yes, to a degree. You should be familiar with key OSHA 29 CFR 1926 subparts (e.g., Subpart L for scaffolding, Subpart M for fall protection, Subpart P for excavations). While you do not need to memorize every subsection number, you must know the requirements and be able to apply them to scenarios.

How much time should I spend on each domain?

The official CHST exam is weighted approximately 40% Hazard Recognition, 35% OSHA Standards, and 25% Safety Planning. Adjust your study time accordingly, but do not neglect any domain. Many test-takers find Safety Planning the most challenging because it requires synthesis of multiple concepts.

Can I use reference materials during the actual CHST exam?

No. The CHST exam is closed-book. You are not permitted to bring any reference materials, notes, or electronic devices. This practice test is designed to help you build the recall and application skills needed for that environment.
