What Is the CHST Certification?
The Construction Health and Safety Technician (CHST) certification stands as one of the most respected credentials in the construction safety industry. Administered by the Board of Certified Safety Professionals (BCSP), this certification validates your expertise in construction-specific safety practices and regulatory compliance.
The CHST exam is a comprehensive 200-question assessment that evaluates your knowledge across seven critical domains. Understanding all seven content areas is essential for success, as the exam covers everything from hazard identification to OSHA regulations specific to construction environments.
To qualify for the CHST exam, you need either: completion of a BCSP Qualified Academic Program, OR a minimum of 3 years of safety work experience (with at least 35% in construction safety), OR an associate's degree in a safety-related field plus 1 year of safety experience.
The certification process requires passing a computer-based exam at Pearson VUE testing centers. With approximately 65% of candidates passing on their first attempt, proper preparation is crucial. The exam uses criterion-referenced scoring with a modified Angoff method, meaning your performance is measured against established standards rather than other test-takers.
