Assessment Guidance
Guidance for achieving higher grades
- 💡In any written or oral assessment, always link tool selection directly to the panel material and damage characteristics; generic answers rarely score full marks.
- 💡When describing repair procedures, use technical terms like ‘low-crown panel’, ‘work hardening’, and ‘featheredging’ to demonstrate depth of knowledge and command of industry language.
- 💡For portfolio evidence, include clear photographs of the repair stages with annotations explaining why each step was taken, referencing manufacturer specifications where possible.
- 💡Before any practical task, state the importance of a thorough visual and tactile assessment to distinguish between surface defects and more severe underlying structural issues.
- 💡When answering assessment tasks, always reference the specific tool or technique by its correct technical name, not a generic term.
- 💡Use manufacturer's data and vehicle-specific repair manuals to support your material identification and repair method choices.
- 💡For practical assessments, plan your workflow meticulously and verbalize safety checks to demonstrate comprehensive understanding.
- 💡Always cross-reference vehicle manufacturer specifications for panel materials before selecting repair techniques.
- 💡When completing written assessments, structure answers around the repair process: preparation, repair, finishing, and protection.
- 💡In practical assessments, justify your tool and material choices clearly to demonstrate underpinning knowledge.
- 💡Always refer to the manufacturer's repair procedures in your answers, as this shows you understand the importance of following specifications.
- 💡Use correct technical terminology, such as 'spot weld drill bit', 'weld-through primer', and 'panel gap', to demonstrate your knowledge.
- 💡In practical assessments, ensure you wear the correct PPE at all times and follow health and safety protocols, as this is a key part of the marking criteria.
Common Mistakes
Common errors to avoid in your coursework
- Selecting abrasive discs that are too coarse for final finishing, causing deep scratches that compromise paint adhesion.
- Applying body filler over unsanded or contaminated surfaces, leading to poor bonding and eventual delamination.
- Misidentifying high-strength steel panels as mild steel and attempting repair with excessive heat or hammering, which can alter the metal’s temper and weaken the panel.
- Neglecting to apply protective coatings (e.g., etch primer, anti-corrosion treatment) to bare metal before filling, resulting in premature rust formation.
- Failing to use appropriate backing supports or dollies when planishing, causing distortion or excessive stretching of the panel.
- Confusing tools suitable for different materials, such as using a hammer designed for steel on aluminium panels causing damage.
- Incorrectly assessing panel damage depth, leading to inappropriate filler thickness or incomplete repair.
- Neglecting environmental controls like dust extraction or proper waste disposal when sanding or mixing fillers.
- Misidentifying aluminium panels as steel, leading to incorrect tool use and potential panel damage.
- Applying excessive heat during paint removal, causing warping or compromising the metal's temper.
- Neglecting to apply corrosion protection to repaired metal, resulting in premature rust.
- Misconception: MIG welding can be used for all types of vehicle repairs. Correction: MIG welding is suitable for many tasks, but spot welding is often required for panel replacement to match OEM standards and reduce heat distortion.
- Misconception: Safety glasses are sufficient for welding. Correction: Welding requires a welding mask with the correct shade to protect eyes from UV radiation and sparks.
- Misconception: Corrosion protection is optional if the repair is painted quickly. Correction: Proper corrosion protection must be applied to bare metal before painting to prevent rust from forming underneath the paint.

Question: A vehicle has a damaged front wing that requires replacement. Describe the steps you would take to remove the old wing and prepare the new wing for fitting, including safety precautions.
- 1.Step 1: Identify the vehicle and consult the manufacturer's repair procedure. Ensure the vehicle is safely supported on a ramp or stands and the ignition is off.
- 2.Step 2: Remove any components that obstruct access, such as the bumper, headlight, and wheel arch liner. Disconnect the battery if necessary.
- 3.Step 3: Locate and remove the fixings (bolts, screws, and plastic clips) that secure the wing to the vehicle body. Use the correct tools to avoid damaging the fixings.
- 4.Step 4: Carefully separate the wing from the body, using a panel separation tool if it is bonded or spot-welded. If spot welds are present, drill them out with a spot weld drill bit.
- 5.Step 5: Prepare the new wing by removing any protective coating, cleaning the mating surfaces, and applying weld-through primer if welding is required. Test fit the wing to ensure alignment.
- 6.Step 6: Fit the new wing, securing it with the correct fixings or welding it in place according to manufacturer specifications. Refit all removed components and check panel gaps.

- 1.Step 1: Clean the damaged area to remove paint, dirt, and grease using a suitable solvent or grinder.
- 2.Step 2: Select the appropriate studs and set the stud welder to the correct power setting for the panel thickness.
- 3.Step 3: Attach the earth clamp to a clean, bare metal part of the vehicle, away from the repair area.
- 4.Step 4: Place the stud welder gun on the dent and press the trigger to weld a stud to the panel.
- 5.Step 5: Use a slide hammer attached to the stud to pull the dent outwards, working from the edges towards the centre.
