WJEC Level 3 Advanced Subsidiary GCE in Design and Technology

WJEC-CBAC

vocational

This unit introduces the fundamental principles of design and technology, covering the iterative design process, material properties, manufacturing systems, and the wider social and environmental responsibilities of designers. Learners develop the ability to critically analyse existing products and apply theoretical knowledge to solve real-world design problems, preparing them for advanced study and industry-linked assessments.

What You Need to Demonstrate

Key skills and knowledge for this topic

Award credit for demonstrating clear links between material properties and product performance in extended responses.
Expect accurate use of technical terminology when describing manufacturing methods and their limitations.
Look for explicit reference to sustainability models (e.g., circular economy) and their application in design proposals.
Credit logical and well-structured evaluation of a product’s aesthetics, function, and user needs.
Assess the depth of analysis when comparing design alternatives, including cost, efficiency, and user experience.

Examiner Tips

Expert advice for maximising your marks

💡Always structure written answers using PEEL (Point, Evidence, Explanation, Link) to ensure clarity and depth.
💡Use real-world product examples to illustrate theoretical concepts—this demonstrates applied understanding and strengthens marks.
💡For design-based questions, sketch clearly annotated diagrams to visualise your ideas; these often gain additional marks.
💡Manage time carefully; allocate proportionally more time to higher-mark questions that require extended analysis.
💡In evaluation tasks, explicitly weigh advantages and disadvantages before reaching a justified conclusion.

Common Mistakes

Pitfalls to avoid in your exam answers

Confusing material properties such as strength and hardness, or stiffness and toughness.
Overlooking the importance of anthropometric data for the 5th–95th percentile user range.
Describing manufacturing processes without linking them to specific product outcomes or scale of production.
Failing to address all three pillars of sustainability (social, economic, environmental) in design critiques.
Presenting superficial product evaluations that lack justification or quantitative evidence.
