COHN exam-day guide
COHN · Prepare for the day ahead.
Your checklist
Government-issued photo ID
Bring at least one current, unexpired government-issued photo ID (driver's license or passport). The name must match your registration exactly - if your license shows a maiden or shortened name, resolve it with the board before test day. Some testing centers require a second form of ID; confirm the specific ID policy with your exam provider.
Appointment confirmation / admission document
Bring the scheduling confirmation or authorization-to-test notice you received, either printed or accessible on your phone before you enter the testing room. Confirm with the provider whether a printed copy is required.
Testing center logistics plan
Know the exact address, building entrance, floor, parking, and check-in procedure. Do a dry run or map the route at the same time of day as your appointment so traffic and construction are not a surprise.
Arrival cushion
Plan to arrive well before your appointment time - many centers deny entry to candidates who arrive after the scheduled start. Confirm the provider's specific late-arrival and check-in cut-off rules in the candidate handbook.
The candidate handbook, read in advance
Read the provider's candidate handbook for permitted and prohibited items, security screening, locker availability, and testing-room conduct. The handbook overrides anything you heard secondhand.
Plan for securing personal items
Expect that phone, smartwatch, notes, bags, and outerwear must be stored away from the workstation. Leave valuables at home or in your vehicle; confirm locker availability with the center.
Approved accommodations documentation (if applicable)
If you requested testing accommodations, confirm in writing that they were approved and will be in place on your appointment date, and bring any confirmation the provider specifies.
Exam identification: COHN vs. COHN-S
Verify which credential exam you are scheduled to sit and that your eligibility (RN licensure and occupational health experience) is on file with the board. Sitting the wrong exam is not correctable on the spot.
Practical comfort items
Bring water and a light snack for before the exam or an authorized break, layered clothing for variable room temperature, and any medically necessary item cleared in advance with the provider.
Contingency plan
Save the provider's contact number and know what to do if you are ill, the center has a technical failure, or you cannot reach the site. Confirm the rescheduling and no-show policy in advance.
Plan the day
Stop learning new content. Re-read your own condensed notes on your weakest domains - commonly occupational health law and recordkeeping, toxicology and exposure assessment, case management, health promotion, and program management - and work a modest set of practice questions to rehearse pacing rather than to cram facts. Re-confirm your appointment date, time, and location and check that your ID meets the name-match requirement. Shift your sleep schedule so you are awake and alert at your appointment hour.
Pack your ID, confirmation document, and comfort items in one place. Re-check the route, parking, and weather. Do a short, low-stress review of summaries and formulas only; do not start a new topic or take a full-length practice test. Eat a normal meal, avoid heavy alcohol, set two alarms, and aim for a full night's sleep.
Eat a real breakfast with protein and moderate caffeine if you normally use it. Leave earlier than the map suggests. Use the restroom before check-in. At the center, present your ID, complete any security screening, store all personal items, and take several slow breaths before the first item - arousal before a long exam is normal and usually fades after ten minutes.
Read the entire stem before looking at the options, and answer the question actually asked. Work at a steady pace and check your time at the quarter and halfway marks; if you are behind, speed up on short recall items and bank time for the longer scenario items. Flag uncertain items, if the platform allows it, and return to them rather than stalling. Use authorized breaks to stand, hydrate, and reset. Change an answer only when you can name a concrete reason the first choice was wrong.
Note how you felt and what appeared in each content domain while it is fresh - useful feedback if you must retake. Follow the provider's stated process for score release and reporting; do not expect unofficial results unless the provider says they are given at the center.
Rules to check
Bring current government-issued photo ID with a name that exactly matches your registration. Candidates without acceptable ID are typically turned away and may forfeit the fee; confirm the exact ID and secondary-ID requirements with your exam provider.
Expect strict prohibitions on personal items in the testing room - phones, smartwatches, notes, and study materials must be stored away from the workstation. Possession of a prohibited item during testing can result in score invalidation; confirm the permitted-item list in the candidate handbook.
Break timing and whether the clock runs during breaks vary by provider. Ask at check-in so you know whether an unscheduled break costs you testing time, and plan your pacing accordingly.
Use only the scratch materials, calculator, or reference tools the center issues. Do not bring your own unless the candidate handbook explicitly permits it.
The exam content is confidential. Discussing, reproducing, or sharing exam questions with others before or after the test violates the nondisclosure agreement and can void your score and affect your credential.
Scoring is against a predetermined standard set by the certifying board rather than against other candidates, so you are not competing with anyone in the room. The exact score scale, pass standard, and result-reporting timeline are board policy - confirm them with the provider rather than relying on what other candidates report.
Report any technical failure, disruption, or irregular proctor behavior to the proctor immediately and document the time and details, then follow up with the provider afterward. Unreported problems are difficult to remedy later.
Attempting to bring in study aids, communicate with others during the exam, or otherwise gain an unfair advantage is misconduct that can invalidate your result. Maintain academic honesty and raise any concern with the proctor.
