Pearson Edexcel A-Level Design and Technology Past Papers & Mark Schemes

Pearson Edexcel A-Level Design and Technology (specification 9DT0) combines theoretical knowledge of materials, manufacturing processes, and design principles with practical design-and-make skills. The qualification is structured around a written examination and a substantial Non-Examined Assessment (NEA) that together assess the full range of design and engineering competencies. The written paper (2 hours 30 minutes, 120 marks, 50%) covers a broad range of technical knowledge. Section A focuses on materials and their applications — students must understand the properties (tensile strength, hardness, toughness, malleability, ductility, thermal and electrical conductivity, density), working characteristics, and typical applications of materials across six categories: woods (softwoods, hardwoods, manufactured boards), metals (ferrous, non-ferrous, alloys), polymers (thermoplastics, thermosetting), textiles (natural, synthetic, blended), composites (carbon fibre, GRP, MDF), and smart/modern materials (shape memory alloys, thermochromic pigments, piezoelectric materials). Section B covers systems and control — mechanical systems (gears, levers, cams, linkages), electrical and electronic systems (circuit components, programmable control), and pneumatic/hydraulic systems. Mathematical skills are explicitly assessed: calculations involving forces, moments, gear ratios, mechanical advantage, velocity ratio, and efficiency. Section C covers design theory and wider issues — the iterative design process, user-centred design, inclusive design, design for manufacture and sustainability, design movements (Arts and Crafts, Bauhaus, Memphis, postmodernism), and the impact of emerging technologies (CAD/CAM, additive manufacturing, CNC machining, robotics) on design and manufacturing practice. The NEA (50%) is a substantial design-and-make project. Students identify a real-world design problem, investigate existing solutions, develop and evaluate design proposals through iterative refinement, manufacture a prototype using appropriate tools and techniques, and evaluate the final outcome against the original specification. The NEA is assessed against four criteria: investigating, designing, making, and analysing and evaluating. With 26 resources covering the written examination, this archive provides targeted practice for the theoretical component of the qualification.
