Koeltechnicus Cat I exam-day guide
Koeltechnicus Cat I · Prepare for the day ahead.
Your checklist
Valid photo identification
Bring the original, unexpired ID document (passport or national ID card). Confirm with the provider which document types they accept and whether a copy is permitted; do not assume a driver's licence is sufficient.
Exam admission letter or appointment confirmation
Print or download the confirmation showing date, time, location and your candidate details. Check the provider's instructions on whether a printed copy is required or a digital version is accepted.
Personal protective equipment
For practical assessments in a workshop or refrigeration plant room, bring safety shoes, safety glasses and gloves. Confirm with the provider exactly which PPE is mandatory and whether it is supplied on site.
Hand tools for practical tasks
Bring the basic hand tools you are accustomed to (spanners, screwdrivers, pipe cutter, deburring tool, torque or adjustable wrenches). Confirm with the provider whether a tool list is issued and whether shared tools are provided.
Pressure gauges and manifold set
If the assessment involves system work, bring your own manifold and gauges so you are familiar with their operation. Confirm with the provider whether personal instruments are allowed or whether calibrated site equipment must be used.
Refrigerant leak detector and thermometer
Electronic leak detector and a calibrated thermometer or clamp probe are commonly used during practical checks. Confirm with the provider whether these are supplied; if personal equipment is allowed, verify it is in good working order beforehand.
Knowledge of the applicable safety and refrigerant regulations
Re-read the sections on safe handling, recovery, charging and pressure testing. Confirm with the provider which regulatory edition or national scheme the exam is based on, as this can change between exam sessions.
Arrival time and travel plan
Plan to arrive well before the stated start time; many centres refuse entry after the briefing has begun. Confirm with the provider the exact reporting time and the late-arrival policy.
Refreshments and any required medication
Practical assessments can run long. Bring water and a snack if permitted. Confirm with the provider whether food and drink are allowed in the assessment area and whether breaks are scheduled.
Review of practical procedures and calculations
Rehearse the standard sequences: leak testing, evacuation, charging by weight, superheat and subcooling checks, and reading pressure-temperature charts. Confirm with the provider which tasks are in scope so you do not over- or under-prepare.
Confirm exam fee and payment status
Check that your registration and fee are settled, as entry may be refused otherwise. Confirm with the provider the payment deadline and refund or reschedule conditions.
Emergency contact and provider phone number
Store the assessment centre's contact number in your phone in case of travel delays. Confirm with the provider the best number to call on the day.
Plan the day
Confirm the appointment in writing, check the venue address and travel time, and read the provider's candidate instructions once more. Gather tools and PPE and check that everything works. Review the practical procedures and the safety rules you will be assessed on, focusing on the areas you find weakest rather than re-reading everything. Get normal sleep and avoid last-minute cramming of new material.
Pack your bag with ID, admission letter, PPE and tools, and place it by the door. Prepare clothing suitable for workshop conditions (no loose sleeves or jewellery). Confirm your transport plan and set two alarms. Eat normally and avoid alcohol. If you feel unwell, check the provider's policy on illness and rescheduling now rather than on the morning.
Eat a proper meal, arrive at the centre with time to spare, and present your ID and confirmation at reception. Listen carefully to the safety briefing and the assessor's instructions, and ask for clarification on any instruction you do not understand before starting. Keep your workspace tidy and your tools organised so you can work efficiently.
Work methodically: read or listen to each task fully, plan the sequence, and carry out safety checks before touching the system. Narrate your reasoning if the assessor invites it. If you make a mistake, correct it calmly and state what you are doing. Watch the clock and leave time to tidy up, recover refrigerant and make the area safe. If equipment fails or a task is unclear, tell the assessor immediately rather than improvising.
Rules to check
Bring the original photo ID specified by the provider; entry may be refused without it. Confirm with the provider which documents are acceptable.
Follow all site safety rules and the assessor's instructions at all times. Report any injury, refrigerant release or equipment fault immediately.
Do not communicate with other candidates during the assessment and do not use notes, phones or other aids unless the provider explicitly permits them. Confirm with the provider what is allowed in the assessment area.
Ask the assessor before leaving the assessment area for any reason. Confirm with the provider the policy on toilet breaks and whether the clock stops during them.
If you do not understand a task instruction, ask the assessor to repeat or clarify it; this is not normally penalised, but receiving substantive help is. Confirm with the provider how clarification requests are handled.
Scoring is based on the assessment criteria set by the provider and awarding body. Confirm with the provider the pass mark, the weighting of practical versus theoretical components, and how partial completion of a task is scored.
If you believe an assessment condition was unfair or equipment was faulty, raise it with the assessor at the time and follow the provider's appeals or complaints procedure afterwards. Confirm with the provider the deadline and process for appeals.
