NIOSH SHO Hazard Control exam-day guide
NIOSH SHO Hazard Control · Prepare for the day ahead.
Your checklist
Government-issued photo ID
Bring the exact ID form your registration confirmation names (passport, driver's license, or national ID). The name must match your registration; if your legal name differs, confirm with the provider before test day how to document it.
Appointment confirmation and test-center address
Save a screenshot and a printed copy of your scheduling confirmation, including the test-center address, arrival time, and any confirmation number. Confirm the delivery format (in-person test center versus remote proctoring) with the provider, because the check-in steps differ.
Review the current candidate handbook or program bulletin
The certifying body's handbook is the authoritative source for ID rules, allowed items, break policy, and scoring. Download the version posted for your exam cycle and read the conduct and scoring sections; do not rely on forum posts.
Confirm permitted reference materials with the provider
Some occupational-safety credential exams are closed-book; others allow specified references. Do not assume either way. Ask the provider in writing whether any tables, standards, or calculator are permitted, and whether an on-screen calculator is built in.
Know the domain weights and question format
Pull the current content outline from the certifying body and note the percentage weight per domain (for example, hazard identification, exposure assessment, hierarchy of controls, ventilation, PPE, and program management). Use the weights to plan your last-day review, not to memorize trivia.
Rehearse the hierarchy-of-controls logic
Be ready to rank controls from elimination and substitution through engineering controls, administrative controls, and PPE, and to justify why a higher-tier control is preferred when feasible. Many scenario items hinge on choosing the most effective control rather than the most familiar one.
Refresh exposure-assessment and ventilation fundamentals
Review the exposure-assessment process (anticipate, recognize, evaluate, control, confirm), sampling strategy basics, and the difference between dilution and local exhaust ventilation. Know qualitatively when general ventilation is inadequate and enclosure or local exhaust is indicated.
Plan logistics: travel, parking, and arrival buffer
Arrive earlier than the provider's stated check-in time to absorb traffic and security screening. Test centers commonly deny entry to late arrivals; confirm the exact cutoff with the provider rather than guessing.
Prepare for the remote-proctoring environment if applicable
If testing remotely, confirm the required platform, camera and microphone checks, room and desk-clearing rules, and permitted items with the provider in advance. Run the system test at least a day early.
Set a sustainable test-day routine
Plan sleep, a normal meal, and hydration so you are not managing hunger or caffeine withdrawal during the exam. Confirm with the provider whether water or snacks are allowed at the workstation or only during scheduled breaks.
Confirm break and scoring rules in advance
Ask the provider whether breaks are scheduled or optional, whether the clock stops, and how unanswered items are scored. Knowing this prevents rushed guessing at the end. Mark as needs_review until confirmed in writing.
Bring nothing not explicitly permitted
Leave phones, smartwatches, notes, and study materials outside the testing room unless the provider lists them as allowed. Test centers typically require personal items to be stored; confirm storage arrangements with the provider.
Plan the day
Re-read the candidate handbook sections on ID, permitted items, break policy, and scoring, and confirm your appointment time and test-center or remote-proctoring logistics in writing. Resolve any open question with the provider now, not on test morning.
Do a weighted review pass: spend time proportional to the published domain weights, focusing on the hierarchy of controls, exposure assessment, ventilation, PPE selection and limitations, and program elements such as training, monitoring, and recordkeeping.
Practice scenario reasoning out loud: for a given exposure, state the hazard, the exposure route, the most effective feasible control, and how you would verify the control works. This mirrors how applied items are written.
Stop adding new material. Review your own error log and summary sheets only, and re-check any formula or definition you have repeatedly missed.
Confirm travel plan, parking, and arrival buffer, or run the remote-proctoring system test and clear your desk area per the provider's rules. Lay out ID, confirmation, and any permitted items.
Do a short, light review in the morning and stop by early afternoon. Protect sleep; do not study late into the night.
Eat a normal meal, arrive ahead of the stated check-in time, and bring only permitted items. At a test center, follow staff instructions for ID verification and secure storage of personal belongings.
Skim one page of high-level reminders, such as the hierarchy of controls and the exposure-assessment sequence, then put notes away. Do not cram new topics in the waiting area.
Read each item fully and identify what is being asked, especially whether it asks for the most effective control, the first action, or the best next step. Answer confident items first and flag uncertain ones if the platform allows review.
Pace against the item count and remaining time; check the clock after roughly each quarter of the exam. Leave time to revisit flagged items and to ensure no item is left blank unless the provider's scoring rules make guessing penalized.
For scenario items, eliminate options that are lower-tier controls when a feasible higher-tier control is offered, and be wary of absolute wording. If a break is available and needed, follow the provider's break procedure exactly.
Note any items or topics you found difficult while memory is fresh, and confirm with the provider how and when results are reported and what the retake policy is.
Rules to check
Bring the ID form specified by the provider, with a name matching your registration; if you lack it or your name differs, contact the provider before test day rather than arriving without it.
Do not bring phones, smartwatches, notes, or study materials into the testing area unless the provider explicitly permits them; store personal items as instructed.
Follow all proctor and test-center instructions, including room and desk clearing for remote sessions, and do not communicate with anyone about exam content during the test.
Do not reproduce, discuss, or share exam content afterward; most credential programs prohibit disclosing exam items, and doing so can jeopardize your certification.
Confirm break rules with the provider in advance: whether breaks are scheduled or optional, whether the clock runs during breaks, and what items you may access.
Confirm scoring rules with the provider, including whether unanswered items are scored as incorrect and whether any guessing penalty applies, then plan your end-of-test review accordingly.
If technical problems occur during a remote session, stop and contact the proctor or provider support immediately rather than troubleshooting alone, and follow their documented incident process.
