CHST stands for Construction Health and Safety Technician. It is a professional certification administered by the Board of Certified Safety Professionals (BCSP) for people working in construction safety, health and environmental functions. The credential is designed for professionals who may support a construction project, job site, contractor, subcontractor or other organisation involved in construction safety.
The certification is particularly relevant to people whose responsibilities include identifying hazards, supporting safe work practices, monitoring compliance and helping prevent construction-related injuries and illnesses. Unlike a general workplace safety qualification, CHST is specifically connected to construction environments.
BCSP currently requires candidates to have three years of experience in construction safety, with at least 35% of their job duties requiring technical skills and knowledge in safety, health and environment. Candidates must also pass the CHST examination and maintain the credential through renewal and recertification requirements.
That makes the certification more than an introductory safety course. It is intended for people who already have meaningful exposure to construction safety responsibilities.
What Does CHST Cover?
Construction sites contain changing hazards. Workers may face risks involving falls, equipment, electrical systems, excavation, materials, temporary structures and changing site conditions. A safety professional therefore needs more than general awareness.
A CHST credential demonstrates competency in construction safety, health and environmental activities. BCSP says CHST professionals may work for owners, general contractors, subcontractors or firms involved in safety, health and environmental practice.
| Area | Why it matters on site |
| Hazard identification | Helps recognise unsafe conditions |
| Risk management | Supports decisions about controlling hazards |
| Safety procedures | Helps establish consistent working practices |
| Construction knowledge | Connects safety controls with site operations |
| Health and environment | Broadens safety beyond immediate physical hazards |
| Communication | Helps workers and supervisors understand requirements |
The practical value comes from connecting these areas. A technically correct safety rule is less effective if workers cannot understand how it applies to their actual task.
CHST Eligibility Requirements
One of the clearest features of the certification is that BCSP does not list a minimum education requirement for CHST. Instead, professional experience is central to eligibility.
| Requirement | Current CHST position |
| Minimum education | None listed |
| Construction safety experience | 3 years |
| Relevant technical duties | At least 35% |
| Examination | Required |
| Recertification | Required every 5 years |
| Annual renewal | Required |
BCSP’s current credential information confirms the three-year experience requirement and 35% technical-duty threshold. It also lists an application fee of $140 and an examination fee of $300, although fees can change, so candidates should check BCSP’s current pricing before applying.
This structure creates an important distinction: CHST is not simply a qualification someone can obtain immediately after completing an introductory course. The experience requirement means applicants should already have practical involvement in construction safety.
How the CHST Examination Process Works
Candidates begin by applying through BCSP. The organisation reviews the application and determines whether the applicant meets the certification requirements. Once approved, candidates can purchase and schedule the examination.
BCSP states that applicants have one year after approval to take and pass the certification examination. The CHST examination is delivered by computer at Pearson testing centres, with official results available after submission.
BCSP also provides exam preparation resources, including examCORE and self-assessment options. The organisation states that examCORE contains more than 1,000 questions and is designed around the CHST examination blueprint. Completing the preparation course does not guarantee a passing result.
A Better Way to Prepare
Candidates should avoid treating the examination as a memory test alone. A stronger preparation strategy is to connect technical concepts with real construction situations.
For example, when reviewing hazard controls, consider how a control would operate on an active site, who would be responsible for implementing it and what could cause the control to fail. This approach links exam knowledge with the practical judgement expected from safety professionals.
Why Experience Still Matters
A certification can demonstrate knowledge, but it does not substitute for site awareness. Construction environments change quickly. A safety professional may need to respond to new contractors, altered work sequences, equipment movement or unexpected hazards.
That is why the CHST experience requirement is significant. It creates a bridge between formal assessment and professional practice.
A documented example is BCSP’s partnership with the National Center for Construction Education and Research announced on 24 March 2026. BCSP reported that NCCER’s Construction Foreman and Construction Superintendent programmes align with topics covered in the CHST blueprint.
This illustrates a broader point: construction safety competency increasingly intersects with workforce development and supervisory responsibility.
CHST Compared With Other BCSP Credentials
CHST is one of several BCSP credentials. The right choice depends on a person’s role and professional experience.
| Credential | Main focus | Experience or education emphasis |
| CHST | Construction safety | 3 years construction safety experience |
| OHST | Occupational hygiene and safety | 3 years relevant experience |
| STS | General safety leadership | Supervisory or broader work experience |
| STSC | Construction safety leadership | Construction-related experience or approved alternatives |
| CSP | Advanced safety practice | Higher education and professional experience |
The comparison shows why candidates should not choose a credential simply because it is widely recognised. CHST is specifically oriented towards construction safety, making it more directly relevant to professionals working around construction operations.
Career Value and Limitations
The main benefit of CHST is professional recognition. A credential can help employers identify candidates who have met an established competency standard.
However, certification does not guarantee employment, promotion or a particular salary. Construction employers may also consider site experience, leadership ability, regulatory knowledge, communication skills and industry-specific expertise.
There is another practical limitation: maintaining certification requires ongoing commitment. BCSP states that credential holders must pay annual renewal fees and earn the required recertification points over a five-year cycle. CHST currently requires 20 recertification points.
The Future of CHST in 2027
The construction safety profession is likely to place increasing emphasis on structured competency, digital training and better integration between workforce development and safety management.
BCSP’s 2026 partnership with NCCER is one concrete example of this direction. The organisations linked construction education programmes with certification blueprint areas, showing how training and professional credentials can increasingly operate as connected career pathways.
There is also evidence that BCSP continues to update its examination development process. Its published schedule includes a CHST job and task analysis panel in December 2026.
That does not mean the certification will fundamentally change in 2027. It does suggest that the competency framework is periodically reviewed to remain relevant to professional practice.
