RETA CIRO exam-day guide
RETA CIRO · Prepare for the day ahead.
Your checklist
Government-issued photo ID
Bring a current, unexpired photo ID (driver's license or passport). The name on the ID should match the name on your RETA registration exactly; if it differs, contact RETA before test day to correct it.
Exam confirmation / appointment record
Bring your registration confirmation, appointment number, or authorization email. The exact document RETA or the testing vendor issues varies, so confirm with the provider which confirmation you must present at check-in.
Candidate handbook and site rules, read in advance
Download and read RETA's current candidate handbook before test day so you know the check-in procedure, permitted items, and scoring/retake policy. Do not rely on secondhand descriptions of the rules.
Approved calculator (if permitted)
Confirm with the provider whether a calculator is allowed and which models are acceptable. Many testing centers prohibit programmable or memory-capable calculators and may supply their own; bring a basic non-programmable unit only if it is explicitly permitted.
Reference material expectations clarified
Ask RETA in advance whether the CIRO exam is closed-book or whether any code books/standards are provided on-screen or in the room. Do not assume you may bring IIAR, ASHRAE 15, or OSHA references unless told otherwise.
Writing materials
Most testing centers supply scratch paper and a pen or marker and prohibit bringing your own. Confirm the policy and leave personal notebooks, loose paper, and printed notes outside the testing room.
Your own condensed review notes (for pre-entry study only)
Bring a one- or two-page summary of formulas, unit conversions, and key safety concepts to skim in the waiting area. It must stay in a locker or your vehicle, not at the workstation.
Directions, parking, and travel plan
Confirm the test center address and parking situation the day before. Plan to arrive with buffer time to clear check-in and security; confirm the required arrival time with the provider.
Know your candidate/member identifiers
Have your RETA member number (if applicable) and any candidate ID from your authorization notice handy in case the proctor asks for them.
Break and comfort plan
Bring water and a light snack only if the site permits food and drink in a locker or waiting area. Confirm break rules in advance, since break availability and time handling differ by location.
Rest and logistics for the night before
Book lodging near the site if you are traveling, set two alarms, and protect sleep. Fatigue hurts performance on calculations and code-recall questions more than one extra hour of cramming helps.
Backup plan for tech or scheduling problems
Save the provider's contact number and RETA's contact information in your phone so you can report a late appointment, site closure, or computer failure immediately rather than losing your slot.
Plan the day
Stop learning new material. Review your weakest domains - refrigeration cycle thermodynamics, system components and controls, safety and hazard management (ammonia detection, ventilation, PPE, emergency response), and regulatory/code fundamentals - using your own notes and practice problems. Re-confirm your appointment time, location, and what you are allowed to bring by checking RETA's candidate materials or contacting the provider.
Do a timed practice set under test-like conditions to rehearse pacing, then review every missed item by concept rather than memorizing the answer. Confirm your ID name matches your registration and resolve any discrepancy now, not at check-in.
Pack your ID, confirmation record, and any permitted items in one place. Lay out clothes and confirm travel time and parking. Do one light pass over formula sheets and safety setpoints, then stop studying by early evening. Avoid alcohol and heavy meals; aim for a normal night's sleep.
Eat a normal breakfast and hydrate modestly. Arrive at the site with buffer time - confirm the required arrival window with the provider rather than guessing. Leave phones, smartwatches, and study notes secured as directed; expect a check-in and identity verification process.
Read the instructions and any tutorial screens before the timer matters to you. Do a quick scan of the interface: question navigation, flagging, calculator tool, and how to submit. Note whether questions are evenly weighted or whether any section dominates the score.
Work in two passes. First pass: answer everything you know confidently and flag anything requiring long calculation or uncertain recall. Second pass: return to flagged items. On calculation questions, write the knowns and units first, then solve; sanity-check magnitudes (pressures, temperatures, flow rates) before selecting an answer.
For safety and code questions, choose the answer that reflects accepted industrial refrigeration practice - isolation and lockout before work, proper ventilation and PPE, correct emergency procedures, and the conservative protective action. Watch for qualifiers like 'first step' and 'except'.
Use remaining time to re-read flagged items and verify that every question has a response; unanswered items score as incorrect. Submit only when you have reviewed the flags, then follow the provider's process for score reporting and any next steps.
Rules to check
Bring valid government-issued photo ID; the name must match your registration record. If it does not, contact RETA or the testing provider before test day.
Electronic devices - phones, smartwatches, earbuds, and recording devices - are generally prohibited in the testing room and must be stored as directed. Confirm the specific device policy with the provider.
Assume the exam is closed-book unless RETA's current candidate materials state otherwise. Do not bring code books, notes, or reference sheets into the testing area without written confirmation that they are permitted.
Breaks: scheduled and unscheduled break rules, and whether the clock keeps running during a break, vary by delivery method and site. Ask before you begin so you are not surprised mid-exam.
Follow all proctor instructions and the site's conduct rules. Suspected cheating, attempting to remove exam content, or disruptive behavior can void your attempt and may affect future eligibility.
Scoring, passing standards, and retake eligibility are set by RETA and can change. Get the current pass point, scoring method, and retake/waiting-period policy directly from RETA rather than relying on what colleagues report.
If you encounter a technical failure, a power outage, or an error in a question, stop and notify the proctor immediately and document what happened; do not attempt to fix the workstation yourself.
Read each question fully before answering and confirm before submitting - most computer-based exams do not let you return once the attempt is finalized. Confirm the review/submission behavior with the provider at the start.
