Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating consistent application of health and safety procedures, including proper use of personal protective equipment (PPE) and vehicle protection prior to commencing inspection.
- Expect clear evidence of correctly referencing and interpreting technical data (e.g., workshop manuals, service schedules, digital platforms) to confirm inspection criteria and vehicle specifications.
- Assessors should look for proficient selection and operation of inspection equipment—such as lifts, multimeters, tyre gauges, and brake testers—with all pre-use checks completed and documented.
- High-quality evidence will show a logical and thorough visual and functional inspection covering all prescribed vehicle systems (e.g., steering, suspension, brakes, lights, tyres) without missing critical safety items.
- Recorded findings must be accurate, itemised, and linked to the manufacturer’s standards; recommendations should be prioritised, costed, and clearly communicated with supporting justification.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always structure your inspection following a standard checklist to ensure completeness; in a practical assessment, narrating your process aloud can demonstrate systematic working to the assessor.
- 💡When recording recommendations, use the PICO (Problem, Implication, Correction, Outcome) framework to show analytical depth and justify the suggested repair or further diagnosis.
- 💡Before any inspection task, verify you have the latest digital service data or correct printout—assessors will award marks for actively cross-referencing specs, not just stating the general procedure.
- 💡If an observation is borderline (e.g., tyre tread depth at 1.8mm), explicitly reference the legal/regulatory threshold and manufacturer’s recommendation to earn full marks for evaluation and decision-making.
- 💡Always use correct technical terminology in your answers; for example, say 'hydraulic pressure' instead of 'fluid pressure' and 'alternator' instead of 'generator'.
- 💡When answering questions about procedures, include safety precautions and the use of appropriate tools, as marks are often awarded for these details.
- 💡Practice drawing and labelling simple diagrams of systems like the cooling system or brake circuit, as these are common in exams and can earn you marks.
Common Mistakes
Common errors to avoid in your coursework
- Learners often overlook preliminary safety checks, such as isolating the vehicle’s power source or conducting a workshop walkaround, leading to a hazardous working environment.
- Incorrect tool selection is frequent—for example, using an analogue multimeter on a digital circuit or failing to calibrate a torque wrench, resulting in unreliable readings or component damage.
- Relying purely on unaided visual inspection and missing subtle defects (e.g., perished rubber bushes, hairline cracks in belts) because they skip tactile or tool-assisted checks as prescribed in the method.
- Record-keeping errors include vague descriptions like ‘brake pads worn’ rather than specifying exact measurements against the manufacturer’s minimum tolerance, making recommendations less actionable.
- Misconception: The battery is the main source of power for the car's electrical systems when the engine is running. Correction: The alternator provides power when the engine is running, and the battery is mainly for starting and when the engine is off.
- Misconception: All brake fluid is the same. Correction: Different types (DOT 3, DOT 4, DOT 5.1) have different boiling points and properties; using the wrong type can cause brake failure.
- Misconception: Tyre pressure doesn't affect fuel consumption. Correction: Under-inflated tyres increase rolling resistance, leading to higher fuel consumption and uneven tyre wear.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A vehicle's cooling system has a thermostat that starts to open at 82°C and is fully open at 96°C. The coolant temperature gauge reads 90°C. Explain what is happening in the cooling system and why the thermostat is partially open.
- 1.Step 1: Identify the given temperatures: thermostat starts opening at 82°C, fully open at 96°C, current temperature 90°C.
- 2.Step 2: Determine the state of the thermostat: since 90°C is between 82°C and 96°C, the thermostat is partially open.
- 3.Step 3: Explain the effect: partially open allows some coolant to flow to the radiator, maintaining engine temperature within the normal operating range.
- 4.Step 4: Conclude: the thermostat regulates coolant flow to keep the engine at optimal temperature, preventing overheating or excessive cooling.
Question: A technician measures the voltage across a 12V battery with the engine running and gets 14.2V. Explain why the voltage is higher than 12V and what component is responsible.
- 1.Step 1: Recall that the battery provides 12V when the engine is off.
- 2.Step 2: When the engine runs, the alternator generates electricity and charges the battery.
- 3.Step 3: The alternator output is regulated to around 14.2V to ensure the battery is fully charged and to power electrical systems.
- 4.Step 4: State that the voltage regulator (often built into the alternator) controls the output voltage.
- 5.Step 5: Conclude: the higher voltage is normal and indicates the charging system is working correctly.
