    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Always verify vehicle is on a level surface and use wheel chocks for safety
    • 💡Follow the equipment manufacturer’s step-by-step sequence for measurements, typically starting with rear axle
    • 💡Note down initial readings before any adjustment to demonstrate evidence of diagnosis
    • 💡Refer to specific vehicle data (e.g., Autodata) rather than relying on memory for alignment tolerances
    • 💡When making recommendations, prioritise safety-critical issues such as excessive tyre wear or loose steering components
    • 💡Always start by checking tyre pressures and ride height before alignment, as these directly affect geometry readings.
    • 💡When recording information, use clear symbols (+ / -) and note any seized or damaged components that prevent adjustment—this demonstrates diagnostic reasoning.
    • 💡In a practical assessment, verbalise your actions to show understanding of safety procedures and the sequence of adjustments (e.g., rear before front, toe last).
    • 💡For recommendations, go beyond 'needs adjustment'—specify potential causes (e.g., worn bush, bent arm) and suggest a repair plan aligned with standard workshop practice.
    • 💡Always conduct a pre-alignment inspection of tyres, suspension, and steering components; a visual check can prevent wasted time and demonstrate safe practice.
    • 💡When recording information, ensure you include the vehicle details, alignment specifications, initial readings, final readings, and any recommendations for parts replacement.
    • 💡Practice using a variety of alignment tools (e.g., optical gauges, laser systems) so that you are confident interpreting different display formats during assessment.
    • 💡Remember to justify your recommendations with evidence: for example, if a track rod end is seized, state how this affects adjustment and why replacement is necessary.
    • 💡Always begin your practical assessment by carrying out a full risk assessment and checking calibration of alignment equipment—this demonstrates underpinning professional competency.
    • 💡When recording results, use the terminology and units exactly as shown on the alignment machine (e.g., degrees and minutes) to avoid ambiguity.
    • 💡If a measurement is out of specification, refer to manufacturer data and state the required adjustment procedure before attempting it; if adjustment is not possible, recommend further investigation.
    • 💡Make sure your written recommendations are clear, prioritised, and linked to the findings—e.g., specifying that uneven tyre wear suggests a camber issue requiring immediate attention.
    • 💡Always follow the equipment manufacturer’s calibration and setup instructions before starting the assessment.
    • 💡During the practical, clearly verbalise your checks (tyre pressures, vehicle height, suspension condition) to demonstrate thorough preparation.
    • 💡Refer to vehicle-specific alignment data throughout the task; never rely on generic specifications.
    • 💡When recording results, note both before and after measurements and highlight any angles that could not be brought within tolerance, explaining why.
    • 💡If the vehicle requires parts replacement before alignment, communicate this as a recommendation in your report.
    • 💡Always refer to the vehicle manufacturer’s specifications and tolerances before starting.
    • 💡Use a systematic approach: pre-checks, measure, adjust, re-measure, and final printout.
    • 💡Double-check all locking nuts and bolts are torqued to specification after adjustment.
    • 💡Practice articulating the relationship between tyre wear patterns and specific misalignment angles.
    • 💡Always refer to the vehicle manufacturer's data when answering questions about specific procedures, such as torque settings or fluid types. This shows you understand the importance of following guidelines.
    • 💡In practical assessments, demonstrate safe working practices at all times. For example, when changing a wheel, apply the handbrake, chock the wheels, and loosen nuts before jacking up the car.
    • 💡Use correct terminology in your answers. Instead of saying 'the thing that stops the car', say 'the braking system components, such as brake pads and discs'. This earns you marks for technical knowledge.

    Common Mistakes

    Common errors to avoid in your coursework

    • Neglecting to check and correct tyre pressures before alignment, leading to inaccurate readings
    • Confusing toe-in and toe-out direction when making adjustments
    • Failing to lock the steering wheel in the straight-ahead position during measurement
    • Overlooking the need for a full tank of fuel or specified load condition as per manufacturer instructions
    • Misinterpreting camber and caster adjustments as interchangeable
    • Failing to secure the vehicle on a level surface with the steering wheel centred and locked, leading to inaccurate baseline measurements.
    • Misinterpreting negative and positive readings for camber and toe, causing adjustments in the wrong direction.
    • Adjusting alignment angles without consulting manufacturer data, resulting in settings that cause poor handling or excessive tyre wear.
    • Neglecting to perform a final post-adjustment check and road test to confirm that the vehicle tracks straight and the steering wheel is centred.
    • Failing to centre the steering wheel and lock it securely before taking measurements, leading to inaccurate toe readings.
    • Adjusting front alignment angles without first checking rear alignment, which can cause a vehicle to crab and compromise overall geometry.
    • Misinterpreting negative and positive values on alignment equipment, resulting in adjustments that worsen handling characteristics.
    • Omitting to recommend replacement of seized or worn suspension components that prevent correct alignment, leaving the vehicle unsafe.
    • Failing to check tyre pressures and vehicle ride height before alignment, leading to inaccurate readings and improper adjustments.
    • Misidentifying adjustable components or attempting to adjust non-adjustable angles, causing potential damage or ineffective alignment.
    • Neglecting to record pre-adjustment measurements or failing to note seized adjusters, which can lead to incomplete work and miscommunication with customers.
    • Overlooking the importance of resetting steering angle sensors after alignment adjustments on vehicles with electronic stability control systems.
    • Failing to set tyre pressures to specification before measurement, leading to incorrect readings.
    • Confusing camber (vertical tilt) with caster (steering axis angle) when making adjustments.
    • Overlooking rear axle alignment, treating a four-wheel alignment as a front-only procedure.
    • Not compensating for run-out when mounting alignment heads, causing measurement errors.
    • Adjusting settings without loosening locking nuts fully, resulting in damaged components.
    • Failing to check tyre pressures and vehicle ride height before alignment.
    • Incorrectly interpreting negative and positive angle readings.
    • Adjusting only front wheel toe on vehicles with fully adjustable rear suspensions.
    • Overlooking worn steering or suspension components that affect alignment accuracy.
    • Misconception: You can use any jack to lift a car. Correction: Only use the vehicle's designated jacking points and always support with axle stands before working underneath.
    • Misconception: Tyre tread depth only needs checking if the tyre looks worn. Correction: Tread depth must be at least 1.6mm across the central three-quarters of the tyre, and you should check regularly with a gauge.
    • Misconception: Brake fluid never needs changing. Correction: Brake fluid absorbs moisture over time, reducing its boiling point and effectiveness. It should be changed according to the manufacturer's schedule.
