The exam
What the CHST exam involves
CHST stands for Construction Health and Safety Technician, a certification awarded by BCSP (the Board of Certified Safety Professionals) to people who work in construction safety. BCSP asks for three years of experience in construction safety where at least 35% of the job duties require technical skills and knowledge in safety, health, and environment (SH&E).
What are the four domains of the CHST exam?
The CHST5 examination blueprint splits the exam into four domains with these weights:
- Hazard and Risk Identification and Control: 36.6%
- Emergency Preparedness, Incident Investigation, and Response: 19.9%
- Safety Program Development, Implementation, and Sustainment: 22.5%
- Leadership, Communication, and Training: 21%
How long is the CHST exam?
BCSP allows four hours. The BCSP pages reviewed for this app do not state the number of questions, so this page does not give one.
What score do you need to pass the CHST exam?
BCSP does not publish a numeric passing score. It sets one minimum passing score on the total score using criterion-referenced methods (Modified Angoff and Bookmark), and candidates do not need a minimum score in each domain. This app's mock uses 28 of 40 as a study target. That figure is our practice bar, not the official pass mark, and the app labels it that way.
How much does the CHST cost?
BCSP lists a $140 application fee, and the examination is $300 for a single attempt. You have one year from the approval of your application to sit for it.
How much of the blueprint does this app cover?
All four domains, with 120 questions in this first release: 44 on Hazard and Risk Identification and Control, 24 on Emergency Preparedness, Incident Investigation, and Response, 27 on Safety Program Development, Implementation, and Sustainment, 25 on Leadership, Communication, and Training. The mock draws 40 questions in 60 minutes in the blueprint's domain weights. It is shorter than the real exam.
What is not covered?
The app lists these limits on its own screens too:
- The question bank covers federal OSHA construction rules (29 CFR 1926) and related federal rules on recordkeeping, hazard communication, record access and bloodborne pathogens. State-plan OSHA rules are not covered.
- Blueprint topics with no federal regulation behind them, such as human behaviour motivation methods, leadership techniques and safety through design, are not yet covered.
Features
A complete study system, on one device
01 / PRACTICE
120 questions across all four domains
Practice domain by domain, from fall protection, excavations and scaffolds to OSHA recordkeeping and training duties. Wrong answers go into a review list, and a readiness score tracks each domain on its own.
02 / MOCK
A 40-question timed mock
40 questions in 60 minutes, drawn in the blueprint's domain weights. The 28 of 40 target is a study bar, since BCSP publishes no numeric pass score, and the app says so on the mock screen.
03 / SOURCES
Written from federal OSHA regulations
The questions are original, written from 29 CFR Part 1926 and related federal rules on recordkeeping, hazard communication, record access and bloodborne pathogens. Under an explanation you see the paragraph it rests on, for example 29 CFR 1926.501(b)(1). No BCSP materials or paid textbooks are reproduced. Everything works offline, with no account.
04 / NOTES
5 study notes and 46 flashcards
One note on the exam format (domains, time allowed, how the pass mark is set, fees and eligibility), written from BCSP's own pages, and one per blueprint domain that cites the regulation paragraph behind each point. The flashcards cover the numbers and duties that are easiest to mix up, at least 11 per domain. The exam format note and the Domain 1 note are open in full before you buy.
