NSSCO Motor Mechanics 6189 exam-day guide
NSSCO Motor Mechanics 6189 · Prepare for the day ahead.
Your checklist
Bring your candidate index number and a photo ID
The index number from your entry documents and a photo ID are normally required for admission to the venue. Confirm with the provider which forms of ID they accept and whether the school-issued candidate slip alone is sufficient.
Bring your own basic hand tools as instructed
For the practical paper you may be told to bring spanners, screwdrivers, pliers, and a feeler gauge. Confirm with the provider the exact permitted tool list, because centres often supply the workshop tool kit and may restrict what you can bring.
Wear workshop-appropriate clothing and closed safety shoes
Loose clothing, open shoes, and jewellery are hazards around rotating parts and hot components. A boiler suit or overalls and closed safety shoes are the safe choice; confirm any specific dress requirement with the provider.
Bring personal protective equipment
Safety glasses or goggles and gloves are standard for practical motor mechanics tasks. Confirm with the provider whether PPE is provided by the centre or must be brought by the candidate.
Bring a pen, pencil, eraser, and a non-programmable calculator
You may need to record readings, complete job cards, and calculate clearances or torque figures. Confirm the calculator policy with the provider before the day.
Carry a clean rag and note-taking materials
A rag keeps hands and components clean during assembly tasks, and a notebook helps you record measurements and observations as you work. Confirm what the centre allows into the workshop bay.
Know your venue, bay allocation, and reporting time
Practical tests run in workshop bays in scheduled slots, sometimes in small groups. Confirm the reporting time and location with the provider, and plan to arrive early.
Read the full task brief before touching any equipment
Identify what is being assessed, the time allowed, and the safety steps expected. Ask the invigilator about anything unclear before you begin, not halfway through.
Plan to work safely and tidily
Marks are commonly awarded for correct use of tools, safe handling of equipment, and keeping the bay clean. Confirm the marking breakdown with the provider so you know what is being observed.
Check the vehicle or rig is safe before starting
Confirm the ignition is off, the battery is isolated where required, and the vehicle is chocked or supported on stands. Never work under a vehicle held only by a jack.
Leave valuables and phones out of the workshop bay
Mobile phones are usually not permitted during the test. Confirm the provider's rule on phones and personal items before the day.
Prepare to explain your work
Practical assessments often include an oral or written element where you describe the procedure and the reason for each step. Practise talking through a task as you do it.
Plan the day
Rehearse the core practical tasks end to end: engine component measurement with a micrometer or vernier caliper, checking and adjusting valve clearances, removing and refitting a wheel and tyre, checking brake pad and disc wear, and testing a battery and charging circuit. Time yourself so you know whether you work fast enough.
Review the safety procedures for each task: correct jacking and axle stand points, battery isolation and the risk of hydrogen gas, handling hot components, and safe use of lifting equipment. Safety is usually marked, so be able to state why each precaution matters.
Practise reading measuring instruments and recording results in the correct units. Know how to convert between metric and imperial where relevant and how to compare a reading against a manufacturer's specification.
Check your tools and PPE: clean them, confirm the feeler gauge leaves are not bent, and make sure your safety glasses are not scratched. Confirm with the provider which tools and PPE the centre supplies.
Confirm the venue, reporting time, bay allocation, and what you are allowed to bring. Re-read any candidate instructions issued by the provider and note any questions to ask on arrival.
Pack your bag: ID, index number, pen and pencil, calculator, PPE, and any permitted tools. Get a full night's sleep; practical work rewards steady hands and clear thinking more than last-minute cramming.
Eat properly and arrive early. Wear your overalls and closed safety shoes, and leave jewellery and loose items at home or in a locker.
Report to the invigilator, present your ID and index number, and listen carefully to the briefing on bay allocation, time limits, and emergency procedures. Ask about anything unclear before the clock starts.
Read the full task brief, identify the tools and equipment you need, and carry out your safety checks. State your safety precautions aloud if an assessor is observing.
Work methodically and talk through your reasoning if invited. Record measurements as you take them, keep the bay tidy, and return each tool to its place after use.
Check your work against the task brief, confirm all fasteners are torqued and components refitted correctly, clean the bay, and return tools and equipment. Use any remaining time to review your recorded readings.
Hand in any job cards or answer sheets, return borrowed equipment, and ask the invigilator whether anything further is required before you leave.
Rules to check
Bring and present the ID and candidate index number required by the provider; confirm the accepted forms of ID in advance.
Follow all safety instructions given by the invigilator and the centre's workshop rules at all times. Unsafe behaviour can lead to removal from the bay.
Do not start any task before the instruction to begin, and stop immediately when time is called.
Mobile phones and smart devices are normally not permitted in the workshop bay; confirm the provider's policy on personal items.
Work only on the vehicle, rig, or component assigned to you. Do not interfere with another candidate's bay or equipment.
Breaks are usually not permitted during a timed practical slot; confirm the provider's policy if you have a medical or access need, and request any arrangement in advance.
Marks are commonly awarded for procedure, safety, accuracy of measurement, and final condition of the work, not only for the finished result. Confirm the marking scheme with the provider.
Any suspected accident, injury, or equipment fault must be reported to the invigilator immediately; do not attempt to repair centre equipment yourself.
