The Construction Health and Safety Technician (CHST) certification is one of the premier credentials offered by the Board of Certified Safety Professionals (BCSP).
It is specifically designed to validate the competence of individuals who devote at least 35% of their primary job duties to safety, health, and environmental practices within the construction industry.
This certification is highly suitable for safety managers, coordinators, technicians, and supervisors who are responsible for implementing, maintaining, and auditing safety programs on construction jobsites.
Earning your CHST demonstrates to employers, clients, and colleagues that you possess the technical knowledge and practical skills necessary to identify hazards, mitigate risks, and ensure a safe working environment on complex construction projects.
What the Course Entails and Exam Details
While the CHST does not require a formal educational "course," the examination itself is a robust assessment of real-world construction safety skills.
The exam blueprint is meticulously organized into four core domains, which together represent the full lifecycle of construction safety management.
Candidates must demonstrate proficiency in Domain 1: Hazard and Risk Identification and Control, which covers the recognition of common construction hazards like falls, electrical risks, and confined spaces.
You must also master Domain 2: Emergency Preparedness, Incident Investigation, and Response, focusing on how to plan for emergencies and react effectively when incidents occur.
For those focusing on "worksite audit" skills, the key area is Domain 3: Safety Program Development, Implementation, and Sustainment. This domain specifically assesses your ability to develop site-specific plans, apply regulatory standards, and conduct comprehensive worksite inspections and audits.
Finally, Domain 4: Leadership, Communication, and Training ensures you can effectively communicate safety principles, train personnel, and motivate safe behaviors across the jobsite.
What to Expect in the Final Exam
The CHST examination is a computer-based test delivered in a professional environment.
It consists of 200 multiple-choice questions, which evaluate both your standalone technical knowledge and your ability to apply safety principles to practical construction scenarios.
You are given a substantial time limit of four hours to complete the examination.
The exam is "close-booked," meaning you are not permitted to use any external study materials during the test. Necessary formulas for safety calculations are usually embedded within the exam interface.
The passing score is determined statistically by the BCSP based on the difficulty of the individual test forms; as long as you achieve the minimum cumulative score required, you will earn your certification.
How to Study and Exam Centers
Effective preparation is essential for success on the CHST exam. We recommend a structured study plan that includes both theoretical review and practical assessment.
Start by carefully reviewing the official BCSP CHST examination blueprint, which outlines the exact weight and knowledge required for each of the four domains.
Because the CHST values hands-on experience, rely on comprehensive study guides and workbooks that use realistic scenario-based questions rather than simple definition recall.
The single most effective method to prepare is by taking high-quality, timed practice tests, such as a focused CHST Worksite Audit Practice Test, to build your stamina and identify any specific knowledge gaps within your desired area of specialty.
When you are ready, you can schedule your exam through the BCSP My Profile portal. From there, you will be directed to schedule your session at one of the hundreds of authorized Pearson VUE testing centers located globally.
Job Opportunities from the Course
Achieving CHST certification significantly enhances your professional credibility and opens the door to a wide range of rewarding career paths within construction safety management.
This credential is a key indicator to the industry that you are a qualified technical expert capable of protecting worksites, managing regulatory compliance, and driving safety performance.
Successful CHST candidates are well-positioned for roles such as:
