About this app

CHST exam prep weighted like the blueprint: every practice set, the free bank and each mock follow the four CHST5 domain weights.

Independent study aid for the BCSP CHST (Construction Health and Safety Technician) exam. Not affiliated with BCSP and not a government app.

WHAT YOU GET
- 1,000 practice questions across 4 Domains: Hazard and Risk Identification and Control (366), Safety Program Development, Implementation, and Sustainment (225), Leadership, Communication, and Training (210), Emergency Preparedness, Incident Investigation, and Response (199).
- A teaching explanation on every question — why the right answer is right, and why each wrong choice is wrong.
- A timed full-format mock exam: 200 questions by domain weight, with flag-and-review. The first mock set is free.
- 1,000 study notes distilling the high-yield points.
- 1,000 flashcards for the facts you have to recall cold.
- Progress tracked domain by domain, so you can see what is holding you back.
- Study offline — a connection is needed only for purchase and restore.

WEIGHTED AND CITED
Hazard and risk control is 36.6% of the CHST5 blueprint, so it gets the largest share of each set and mock. Mock sets never repeat a question or pad a domain. Each explanation names what it rests on: a 29 CFR regulation (a legal requirement) or OSHA, FEMA or NIOSH guidance (recommended practice). A CHST study guide you can check.

WHO IT IS FOR
- Site safety staff working toward the CHST certification
- Candidates who want a CHST practice test that follows the domain weights
- Foremen and tradespeople moving into a safety role
- Anyone studying in short breaks: sets resume where you left off

HOW THE EXAM WORKS
The CHST exam is computer-delivered at a test center: 200 multiple-choice items with four options under the CHST5 blueprint (effective August 2024). BCSP does not publish a fixed passing score, so the app shows practice scores, never a pass prediction. Check eligibility and fees with BCSP.

CURRENT CONTENT
Version 1.0 covers all four domains with CHST practice questions written from OSHA regulations on the eCFR (29 CFR 1926, 1910, 1903, 1904) and OSHA, FEMA and NIOSH guidance. All items are text-based and original.

PRICING
One-time purchase unlocks more reviewed questions and mock sets. No subscription, no ads.

FREE PREVIEW
CHST prep starts free: a 10-item starter set across all four domains, then a domain-weighted free bank with full explanations and a retry of missed items. No account and no signup required.
