Assessment Guidance
Guidance for achieving higher grades
- 💡Use a structured approach like PDCA.
- 💡Include safety considerations in procedures.
- 💡Practice writing clear instructions.
- 💡Use a structured template to assess requirements, ensuring all aspects (legal, technical, human) are covered.
- 💡Document your decision-making process clearly, showing how you weighed pros and cons.
- 💡When specifying a test procedure, always include pass/fail criteria and any control measures.
- 💡Prepare a resource checklist and verify availability before proposing the procedure.
- 💡Tailor your communication to the audience; use simple language and visual aids if needed for non-technical staff.
- 💡Record test results thoroughly, including any deviations or unexpected outcomes, and suggest improvements.
- 💡Create a step-by-step guide with photos or diagrams to facilitate accurate replication.
- 💡Use your workplace evidence to show how you involved colleagues in developing the procedure—assessors value collaborative input and buy-in.
- 💡Reference relevant regulations and standards (e.g., GGF guidelines, CDM 2015) when justifying your chosen procedure to demonstrate professional awareness.
- 💡Include photographic or video evidence of the testing phase to strengthen your portfolio and provide clear visual proof of the procedure in action.
- 💡Ensure your documentation is clear and accessible; consider producing a one-page quick reference in addition to the full procedure to aid uptake.
- 💡Always use correct technical terms and units in your answers. For example, specify 'mm' for dimensions and 'N/mm²' for stress.
- 💡When describing processes, include the purpose and the effect on the glass properties. For instance, explain that toughening creates compressive stress on the surface.
- 💡In quality control questions, always mention the relevant British or European standards (e.g., BS EN 12150) to show awareness of industry regulations.
Common Mistakes
Common errors to avoid in your coursework
- Skipping risk assessment before testing.
- Not considering resource implications.
- Failing to document procedure clearly.
- Failing to fully assess all requirements, leading to oversight of critical safety or quality aspects.
- Not considering the full range of potential procedures, thus missing more efficient alternatives.
- Specifying a test procedure that lacks measurable outcomes or clear success criteria.
- Overlooking necessary resources or special requirements such as specific training or environmental controls.
- Communicating the procedure without a proper rationale, causing resistance or misunderstanding among team members.
- Conducting testing informally without recording data, making validation difficult.
- Providing details that are too vague for others to replicate, assuming prior knowledge.
- Overlooking glass-specific risks such as manual handling injuries, breakage from stress points, or inadequate edge protection when proposing new procedures.
- Failing to consider the availability and cost of specialist resources (e.g., suction lifters, glazing robots) leading to impractical procedures.
- Inadequate testing under real work conditions, resulting in procedures that fail during actual fabrication or installation.
- Poor documentation that lacks clarity on critical steps, making it difficult for others to replicate the procedure consistently.
- Misconception: Toughened glass cannot be cut after processing. Correction: Toughened glass must be cut and shaped before toughening; any post-processing will cause it to shatter.
- Misconception: Laminated glass is stronger than toughened glass. Correction: Laminated glass is not necessarily stronger but is safer because it holds together when broken; toughened glass is stronger in terms of impact resistance.
- Misconception: All glass defects are visible to the naked eye. Correction: Some defects like internal stresses or micro-cracks require special equipment such as polariscopes or ultrasonic testing.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A glass processor needs to cut a rectangular pane of glass that is 1200 mm by 800 mm. The cutting process uses a diamond wheel and the glass is 6 mm thick. Calculate the perimeter of the pane and the area of glass cut. If the cutting speed is 5 m/min, how long will it take to cut the perimeter?
- 1.Step 1: Identify the dimensions: length = 1200 mm = 1.2 m, width = 800 mm = 0.8 m.
- 2.Step 2: Calculate perimeter: P = 2 × (length + width) = 2 × (1.2 + 0.8) = 2 × 2.0 = 4.0 m.
- 3.Step 3: Calculate area: A = length × width = 1.2 × 0.8 = 0.96 m².
- 4.Step 4: Calculate cutting time: time = distance / speed = 4.0 m / 5 m/min = 0.8 minutes = 48 seconds.
Question: A batch of 200 glass panels is produced. During quality inspection, 12 panels are found to have defects: 5 have edge chips, 4 have scratches, and 3 have bubbles. Calculate the percentage of defective panels and the percentage of each defect type. If the company targets a defect rate of less than 5%, does this batch meet the target?
- 1.Step 1: Total defective panels = 12.
- 2.Step 2: Percentage defective = (12 / 200) × 100 = 6%.
- 3.Step 3: Percentage of edge chips = (5 / 200) × 100 = 2.5%.
- 4.Step 4: Percentage of scratches = (4 / 200) × 100 = 2%.
- 5.Step 5: Percentage of bubbles = (3 / 200) × 100 = 1.5%.
- 6.Step 6: Compare to target: 6% > 5%, so the batch does not meet the target.
