Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for accurately describing the properties and automotive applications of at least two non-glass glazing materials (e.g., polycarbonate, acrylic), including optical clarity, impact resistance, and thermal behaviour.
- Award credit for demonstrating the correct selection of material and tools based on the shaping requirement, referencing material data sheets and vehicle specifications.
- Award credit for preparing a clean, well-organised workstation with appropriate tooling, securing devices, and contamination control measures.
- Award credit for shaping the material to the specified template or pattern, producing smooth edges, accurate dimensions, and no visible defects such as cracking, melting, or distortion.
- Award credit for identifying potential shaping problems (e.g., overheating, stress marks) and describing effective corrective actions, with evidence of testing or adjustments made.
- Award credit for completing all required documentation, including material batch numbers, dimensions, shaping parameters, quality checks, and any deviations, in accordance with organisational procedures.
Assessment Guidance
Guidance for achieving higher grades
- 💡Verbally justify your material choice and shaping parameters to the assessor, linking them to the real-world vehicle application and safety requirements.
- 💡Always test your technique on a sample piece first and demonstrate how you inspect for quality, showing a proactive approach to error prevention.
- 💡Maintain an ongoing record of the shaping process, including any adjustments or problem-solving, to provide comprehensive evidence of your competence.
- 💡Keep the work area immaculate and free of contaminants throughout the assessment, as assessors will be looking for adherence to health and safety and contamination control standards.
- 💡Always use the correct terminology, such as 'urethane adhesive' instead of 'glue', and 'cold knife' instead of 'cutter'.
- 💡In practical assessments, narrate your actions to the assessor, explaining why you are doing each step.
- 💡Keep up-to-date with manufacturer guidelines and industry updates, as these are often referenced in assessments.
Common Mistakes
Common errors to avoid in your coursework
- Assuming that all non-glass glazing materials can be shaped with the same tools and speed settings, leading to melting (especially with acrylic) or chipping.
- Neglecting to consult material data sheets for heat resistance and forming limits, resulting in deformation or weakened areas after shaping.
- Failing to adequately secure the workpiece, causing movement during cutting or routing, which compromises accuracy and increases risk of injury.
- Overlooking the importance of personal protective equipment (PPE) when machining plastics, such as respiratory protection against fine dust and eye protection against flying chips.
- Misconception: All windscreens are the same and can be fitted interchangeably. Correction: Windscreens vary by vehicle make, model, and year, and may have sensors or heating elements that require specific handling.
- Misconception: Once the new windscreen is fitted, the vehicle can be driven immediately. Correction: Adhesive needs time to cure; driving too soon can compromise the bond and safety.
- Misconception: Toughened glass can be cut or repaired like laminated glass. Correction: Toughened glass shatters into small pieces and cannot be repaired; it must be replaced.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A customer's windscreen has a crack longer than 30mm. Explain the process you would follow to replace it, including safety and quality checks.
- 1.Step 1: Assess the damage and confirm replacement is needed (crack >30mm cannot be repaired).
- 2.Step 2: Prepare the vehicle: cover interior, disconnect battery if needed, and remove wipers and trim.
- 3.Step 3: Remove the old windscreen using appropriate tools (e.g., cold knife, wire cutter) while wearing PPE.
- 4.Step 4: Clean and prepare the bonding surface, ensuring it is dry and free from old adhesive.
- 5.Step 5: Apply primer and adhesive according to manufacturer instructions, then fit the new windscreen using suction cups.
- 6.Step 6: Press the glass into place, check alignment, and allow adhesive to cure before handing back to customer.
Question: Calculate the total time to replace a windscreen if the removal takes 30 minutes, preparation 15 minutes, fitting 20 minutes, and curing time is 2 hours. Express the total in hours and minutes.
- 1.Step 1: Add the non-curing times: 30 + 15 + 20 = 65 minutes.
- 2.Step 2: Add the curing time: 65 minutes + 120 minutes = 185 minutes.
- 3.Step 3: Convert to hours and minutes: 185 minutes = 3 hours and 5 minutes.
