ExploreAbout this exam
The Construction Health and Safety Technician (CHST) credential is a certification awarded by the Board of Certified Safety Professionals (BCSP) to construction safety practitioners who demonstrate technical competence in safety, health, and environment (SH&E) work on construction projects and jobsites. It is designed for people whose SH&E duties may be all or part of their job, and whose expertise may cover one or more significant projects. CHST candidates may work for an owner, general contractor, subcontractor, or a firm involved in SH&E practice and/or construction - the program explicitly recognizes employers who assign construction SH&E responsibility to workers in key leading roles. Many practitioners use the CHST as a stepping stone to broader SH&E roles.
The exam is delivered by computer at Pearson test centers, and official results are available as soon as the exam is submitted. Content follows BCSP's published CHST blueprint, which organizes the exam around SH&E program management and evaluation, hazard identification and control, incident investigation and reporting, employee training and communication, and regulatory compliance and recordkeeping. BCSP publishes the blueprint and reference list as free PDFs - download both before planning study time.
Preparation options include self-directed study from the published references and BCSP's examCORE online course, a self-paced program built around the blueprint areas with pre- and post-assessments. This page is an independent study resource and is not affiliated with or endorsed by BCSP.
What you'll study
About BCSP CHST preparation
What are the eligibility requirements for the CHST exam?
You need three years of experience in construction safety in which at least 35% of your job duties require technical skills and knowledge in safety, health, and environment. You must also pass the CHST examination and then maintain certification by paying an annual renewal fee and meeting recertification requirements. Applicants must disclose criminal convictions or professional license actions, which BCSP reviews confidentially.
How much does the CHST exam cost?
The CHST examination is $300 for a single examination. You can buy it during the application process as an application-and-exam bundle, or purchase it after your application is approved. BCSP advises checking the current Credentials At-A-Glance PDF for up-to-date pricing, since fees can change.
How long do I have to take the exam after I'm approved?
Once BCSP determines you are eligible, you have one year to take and pass the examination. The same one-year window applies to sitting for any purchased examination authorizations. Plan your study schedule around that deadline rather than assuming you can defer indefinitely.
What is the exam format and when do I get results?
The exam is delivered by computer at a Pearson test center, and Pearson operates hundreds of test centers worldwide. You schedule through a single sign-on link from your BCSP My Profile. Official results are available as soon as you submit your exam, so there is no waiting period for a score report.
What happens if I fail - when can I retake it?
You may schedule the exam at any time available as long as it is at least six weeks from your last exam attempt. That six-week gap is a hard minimum, so build a study plan for the retake rather than trying to book immediately. Candidates who used examCORE may be eligible for a free access extension.
How do I keep the CHST once I pass?
Certificants pay an annual fee to retain use of BCSP credentials. In addition, all credential holders must stay current with changes in professional practice and report their activities to earn recertification points, which are required every five years. The credential is therefore maintained through ongoing renewal rather than expiring on a fixed date.
How should I structure my study time?
Start with BCSP's CHST Exam Blueprint and Exam References PDFs, which define the content areas and the source material the exam is built from. Work domain by domain against those references, then use practice questions to find weak areas. BCSP's examCORE course is organized around the blueprint and includes pre- and post-assessments to track progress.
What causes candidates to struggle most?
Two common problems: studying generic safety content instead of the published blueprint and reference list, and underestimating the regulatory compliance and recordkeeping material, which rewards precise knowledge of requirements rather than general principles. A third is treating a failed attempt casually - the six-week wait is short, so use it to target the specific areas that went poorly.
Is a prep course required to sit for the exam?
No. BCSP's examCORE is an optional, self-paced online course covering each blueprint area, with pre- and post-assessments and access to over 1,000 examCORE questions. BCSP notes that completing examCORE does not guarantee you will pass the exam, so treat it as one input alongside the published references.
