CHST (Construction Health and Safety Technician)

CHST eligibility requires 3 years of experience in construction safety specifically, with at least 35% of actual job duties requiring technical safety, health, and environmental (SH&E) skills and knowledge, a bar meant to filter for real substantive safety responsibility, not just a job title that happens to touch on it. There's no minimum formal education requirement attached to it, which is part of why BCSP credentials are common among people who moved into safety from the trades or a superintendent track rather than from a safety-specific degree program.

The exam itself runs 4 hours, administered through BCSP directly. Cost runs around $300 for the standard exam fee alone, with a combined application-plus-exam option around $426, or a bundle option in the $550 to $676 range depending on what's included.

It's worth not confusing CHST with OSHA 30. OSHA 30 is a 30-hour training course and completion card, not a credential requiring years of documented experience or a separate exam. CHST sits at a meaningfully higher bar: real verified construction safety experience plus a 4-hour exam through BCSP, a national board, not a training provider.

Once earned, CHST sits on a 5-year recertification cycle requiring 20 continuing education points, including at least 0.5 points specifically from ethics courses, plus a $145 renewal fee. It's one of several related BCSP credentials, alongside Associate Safety Professional (ASP) and Certified Safety Professional (CSP), each with its own eligibility bar; CSP generally sits as a longer-term, more advanced goal beyond CHST rather than a side-by-side alternative to it.
