Construction Health and Safety Technician (CHST): A Career Path Into Safety Leadership

At a Glance

• The CHST is administered by the Board of Certified Safety Professionals (BCSP) and is designed specifically for construction safety roles.
• Eligibility is based on three years of construction safety experience, with at least 35% of job duties involving technical safety, health, and environmental (SH&E) work. There is no listed minimum education requirement.
• The exam is 200 multiple-choice questions over four hours, delivered through Pearson VUE.
• Once your application is approved, you have one year to sit for the exam, and you must wait at least six weeks between attempts if a retake is needed.
• CHST sits between entry-level safety credentials and the Certified Safety Professional (CSP), making it a realistic mid-career target for practitioners without a four-year degree.
• BuilderFax stores your CHST and related credentials in one place so employers and general contractors can verify them instantly.

Demand for experienced construction safety professionals continues to grow as contractors place greater emphasis on regulatory compliance and jobsite safety. For a worker who already understands job sites, inspections, and hazard recognition, the Construction Health and Safety Technician (CHST) credential is one of the most direct routes from field work into a formal safety career.

Unlike many professional certifications, CHST is not gated behind a college transcript. It’s built around verified, hands-on experience, which is exactly why so many superintendents, safety coordinators, and site supervisors treat it as the realistic next step in their careers.

This article explains what the CHST covers, who is eligible, what the exam involves, what it costs to earn and maintain, and how it fits into a longer-term safety career path.

What Is the CHST?

The CHST is issued by the Board of Certified Safety Professionals (BCSP) for people whose job duties involve safety, health, and environmental (SH&E) responsibilities on construction projects, whether that’s their full-time role or a significant part of a broader job. Candidates may work for an owner, a general contractor, a subcontractor, or a firm that provides construction safety services.

BCSP built the CHST around a simple idea: many employers assign construction safety responsibilities to people already leading crews and managing sites, not just to dedicated safety officers. The credential formalizes that experience into a portable, third-party verified certification. Many public agencies, contractors, and owners recognize CHST when hiring or qualifying construction safety personnel. However, recognition varies by employer and by project rather than being a universal statewide licensing requirement.

Eligibility Requirements

BCSP’s current eligibility standard for CHST is more straightforward than it once was. To qualify for the exam, you need:

• Three years of experience in construction safety, where at least 35% of your job duties required technical skills and knowledge in safety, health, and environmental (SH&E) practice.
• BCSP lists no specific minimum education requirement for this pathway.
• Disclosure of any criminal convictions or prior actions against a professional license or credential, which BCSP reviews confidentially and may use to deny an application

Experience can come from a range of roles, including work for an owner, general contractor, subcontractor, or a firm that provides construction safety services. BCSP reviews your submitted experience during the application process before approving you to sit for the exam.

What’s on the Exam

The CHST exam consists of 200 multiple-choice questions, with a four-hour time limit, delivered by computer at a Pearson test center. The exam blueprint, published by BCSP, outlines domains covering program management, worksite auditing, training, and professional responsibility. Questions are written to reflect the real work of a construction safety technician, not abstract theory.

CHST Exam Snapshot

• Format: 200 multiple-choice questions
• Time limit: 4 hours
• Delivery: Computer-based testing through Pearson at test centers worldwide.
• Exam fee: $300 for a single examination (confirm current pricing on BCSP’s Credentials At-A-Glance sheet, since fees can change).
• Results: Available immediately after you submit the exam.
• Retake wait time: At least six weeks from your last exam attempt.

Step-by-Step: How to Get CHST Certified

1. Confirm you meet BCSP’s construction safety experience requirement. Document three years of experience with at least 35% of your duties tied to SH&E work.
2. Create a BCSP account through the My Profile portal on bcsp.org.
3. Submit your application and fee. BCSP reviews your experience documentation and confirms eligibility.
4. Wait for eligibility approval. Once approved, you have one year to purchase and sit for the exam.
5. Study using the CHST blueprint and reference list, both published by BCSP, or consider BCSP’s self-paced CHST examCORE course for structured review.
6. Schedule your exam through Pearson, using the single sign-on option available in your BCSP profile.
7. Pass the exam and maintain certification. CHST holders pay an annual renewal fee and must earn recertification points on BCSP’s five-year cycle to keep the credential active.

Where CHST Fits in a Safety Career

CHST sits above entry-level credentials like OSHA 30-hour training and the Safety Trained Supervisor Construction (STSC) credential, and below the Certified Safety Professional (CSP), which requires a bachelor’s degree. For many experienced construction safety professionals who do not hold a bachelor’s degree, CHST is the highest BCSP construction-specific certification currently available to them.

Many safety managers on large construction projects build entire careers around the CHST without ever pursuing the CSP, since the CSP’s degree requirement is a hard gate that CHST does not share. That said, CHST is also one of the credentials BCSP accepts as a qualifying prerequisite if a professional later decides to pursue the CSP.

For someone coming up through the trades, the practical value of CHST shows up in job postings before it shows up anywhere else. Site Safety and Health Officer positions on federal and larger commercial projects frequently list CHST as a preferred or required qualification, alongside years of hands-on construction experience. Holding the credential can also support a move from field supervision into a dedicated safety role, since it gives a hiring manager a standardized way to evaluate a candidate’s safety knowledge without relying solely on résumé claims or references.

Maintaining Your CHST Certification

Certification is not a one-time event. BCSP requires CHST holders to pay an annual fee to retain use of the credential, and to earn recertification points through ongoing professional development, submitted on a five-year cycle. This can include attending industry conferences, completing continuing education, publishing safety-related content, or delivering training. Most working safety professionals accumulate these points naturally through the normal course of their job.

If your certification lapses, the specifics of reinstatement depend on your timing and status with BCSP, and can include reapplying and, in some cases, meeting current eligibility requirements again. It’s worth checking BCSP’s current recertification and reinstatement policies directly rather than assuming a fixed outcome, since these policies are subject to change.

‍

CHST remains one of the most practical safety credentials available to someone already working in construction. It rewards verified field experience over classroom time and gives contractors an ANSI/ISO 17024-accredited way to confirm that a safety technician understands the job. For workers looking to move from the field into a dedicated safety role, and for those who may never pursue a four-year degree, CHST is often the clearest and most achievable next step.
