CHST study guide: a six-week plan by domain

Start with the blueprint and the clock

BCSP's blueprint has four domains: hazard and risk identification and control 36.6%, safety program development, implementation and sustainment 22.5%, leadership, communication and training 21%, and emergency preparedness, incident investigation and response 19.9%. BCSP's credentials sheet gives you 4 hours at a Pearson test center. Before you plan anything, check you qualify: the eligibility guide covers the three years of construction safety experience BCSP asks for.

Domain 1 holds 31 knowledge items, from hot work and excavations to silica, noise and concrete work. That is why more than a third of your time belongs there.

A six-week CHST plan

Plan four sessions a week: two for topic study, one for questions and one for mixed review. Stretch the plan if work gets in the way. To fit it to your own exam date and weekly hours, use the CHST study plan builder. For quick recall of subpart numbers, formulas and controls between sessions, flip through the free CHST flashcards.

Week 1: baseline and falls

Take the free 10-question check and write down your score in each domain. Then study working at heights: fall protection (Subpart M) and ladders (Subpart X). Learn the hierarchy of controls here, because every later hazard uses it, then practice it on construction scenarios with the hierarchy of controls drill.

Week 2: structures, earth and power

Study scaffolds (Subpart L), excavations (Subpart P) and electrical (Subpart K). For each, write the competent person's duties in your own words and the one number you would never get wrong. For excavations, the trench sloping calculator turns the soil type and depth into a slope you can check by hand.

Week 3: lifting, spaces and exposures

Cover cranes and derricks (Subpart CC), confined spaces (Subpart AA) and the health hazards guide for silica, lead and noise. Add the tool, material handling and housekeeping items from the blueprint's hazard list.

Week 4: the safety program

This is Domain 3. Study site-specific safety plans, inspections and audits, job hazard analysis, risk management and incident causation. Work through OSHA recordkeeping and practice the incidence rate arithmetic until it is automatic, using the OSHA incident rate calculator to check your hand answers. Add the leading and lagging indicators your own site uses.

Week 5: people and emergencies

Domain 4 asks how you lead, train and communicate. Domain 2 asks how you plan for and respond to emergencies, and how you investigate afterward. Study emergency action plans, incident command, first aid, universal precautions and root cause methods. Practice the question type both domains share: what is the first action, or the best control?

Week 6: timed mixed review

Sit full-length practice at the real exam's 4 hours. Mix all four domains and review every miss by cause: unfamiliar rule, misread stem, two true options, or fatigue. Retake the free check and compare it with week 1.

Study OSHA by section number

Cite 29 CFR 1926 by section when you study, and read the current text in your own copy. Our guides give section numbers and plain-language summaries, never the standard's text. Keep a short log: the duty, the section, and what the competent person must do about it. For fall protection, the fall clearance calculator turns the arrest limits in 1926.502(d)(16) into a worked number.

Calculation items are quick points once the formulas are automatic, so keep the CHST formulas page beside you for incident rates, fall clearance, noise dose and sling loads.

Use the four hours well

Four hours is long, and drifting is a bigger risk than rushing. Answer what you know, mark what you do not, and use the saved time on a second pass. Leave no question blank. The cost and scheduling guide covers booking once your practice scores are where you want them.

CHST study material: books, OSHA text and free practice

The one book every CHST candidate needs is free: OSHA 29 CFR Part 1926, the construction standards, plus Part 1904 for recordkeeping. Read them on OSHA's site and keep your own notes by section number. If you buy a CHST study guide book, check that it is written to the current CHST5 blueprint and its four domain weights, and that its practice questions explain each answer. The study options compared page lists what to check before you pay anyone.

Free practice to pair with each week of the plan:

• The free 10-question check: your score by domain, every answer explained, no signup.
• The CHST mini-mock: 25 questions on a 30-minute clock. The first 5 are open to anyone, and an email unlocks the other 20.
• The class quiz (free PDF): printed practice questions with an answer key on page 2. No email.
• The CHST flashcards for subpart numbers, terms and formulas, and the CHST formulas page for the math.

FAQ

What is the best CHST study guide?

The best one follows BCSP's blueprint: four domains weighted 36.6%, 22.5%, 21% and 19.9%, tied to the OSHA 1926 subparts you will be asked about. This guide does that for free, week by week. Whatever you use, test it against the free check so you see which domain still costs you points.

What books do I need for the CHST exam?

Start with OSHA 29 CFR Part 1926 and Part 1904, both free on OSHA's site. A commercial CHST study guide book is optional. If you buy one, make sure it is written to the CHST5 blueprint and explains each practice answer.

Is there a free CHST study guide PDF?

This guide is free to read online. For paper, print the class quiz (free PDF), which needs no email, and turn your exam date and weekly hours into a printable schedule with the CHST study plan builder.

What CHST study material is free?

This six-week plan, the OSHA standards, the free 10-question check, the 25-question mini-mock, the class quiz PDF, the CHST flashcards, the formulas page and one guide for each major OSHA construction subpart. That covers every domain before you spend anything.

How do I study for the CHST exam?

Take the free check to set a baseline by domain. Spend the most time on hazard and risk identification and control, the 36.6% domain. Study OSHA by section number, practice the incident rate and fall clearance math until it is automatic, and finish with full-length practice on the 4-hour clock.

Where do the practice questions come from?

Every question is original and written to BCSP's published CHST blueprint. Each answer explains why the key is right and names the 29 CFR 1926 or 1904 section to read yourself.
