GCSE Design and Technology - NEA Guide - 3.2 Quality and Accuracy (AO2 12 marks)

Uploaded by Cart

3.2 Quality and Accuracy guidance for GCSE Design and Technology NEA explains what students must evidence to earn AO2 marks. It requires clear photographic and/or video evidence showing the prototype’s intended function, user/client needs, problem solution, and specification compliance. It also details accuracy judgement criteria: fit between parts, surface and edge finish, measurements against tolerances, and matching between off-the-shelf and made parts. The guide stresses demand-appropriate outcomes, avoids double credit, and clarifies CAM and scaled project expectations.

GCSE Design and Technology – NEA Guide 3.2 Quality and Accuracy (AO2 12 marks) Exemplars of 3.2 Manufacture – quality and accuracy Use this live link to view the latest exemplar materials for this assessment grid. What the NEA content requires students to do: 3.2a Measuring the degree to which the prototype performs as intended Students are required to include photographic and/or video evidence sufficient to show that the prototype they have made: 1. Functions as intended (or does not) . 2. Meets the needs of the user/client (or does not) . 3. Solves the identified problem (or does not) . 4. Meets the full list of specification criteria (or attempted to) . Students will do this effectively through their choice of media and the range of evidence they submit to showcase the final finished prototype in use. Prototypes which fail to “prove” their functionality will struggle to gain high credit. 3.2b The prototype is accurately assembled and finished to a high quality. Students are required to include photographic and/or video evidence sufficient to build a judgement relating to accuracy, including: 1. The relationship between separate parts (how close they fit together, any gaps) . 2. The finish of surfaces and edges of parts (how much the surfaces or edges are improved) . 3. The measurements of parts against intended measurements (how accurate parts are in relation to tolerance) . 4. The relationship between off the shelf parts and made parts (how well parts that are professionally made and bought in fit with those being made by the student) . © Pearson Education Ltd 2023 .

Version 2 GCSE Design and Technology – NEA Guide How this assessment grid differentiates student evidence of quality and accuracy. Quality and accuracy evidence will be found entirely from the photographic evidence of the chosen design being made into the final prototype. Students must provide sufficient evidence of the final prototype, which includes: • views of all sides • the prototype functioning using video where necessary (i.e. to capture movement or functions that cannot be captured through still images alone) . Prototypes will be judged on their appropriate level of demand for GCSE, which is a national standard set by all awarding organisations for the subject of D&T. Prototypes that sit above this national standard will not receive any extra credit due to higher than required levels of complexity, demand, quality, and accuracy. Similarly, prototypes which sit below this national standard will struggle to justify access to all quality and accuracy marks, if the made outcome is largely simplistic, undemanding, and not sufficiently challenging. The quality of materials and availability of higher quality materials will not favour the judgement, to ensure that comparability between centres is acknowledged. The use of Computer Aided Manufacture (CAM) will not favour the judgement for quality and accuracy, where it is unclear whether the student did or did not carry out the use of CAM independently. Students wishing to gain credit for CAM work will need to ensure the skilled use of CAM is documented in their evidence, through the photographic evidence and written annotation of these processes being student led. © Pearson Education Ltd 2023 .

Version 2 GCSE Design and Technology – NEA Guide Any evidence of quality and accuracy in the design and development of design evidence (2 .1 and 2.3), will not gain credit within grid 3.2. This will avoid double crediting work which has already gained credit in 2.1 and 2.3. Advice for scaled outcome projects. It is required that scale models retain a focus on quality and accuracy, to avoid the made outcome being comparable to a model that would be suitable to appear in 2.3 developmen

FAQs

What evidence must students include for 3.2a measuring performance?

Students must submit sufficient photographic and/or video evidence to show whether the prototype functions as intended, meets user/client needs, solves the identified problem, and meets the full specification criteria (or shows attempted compliance).

How is accuracy judged under 3.2b?

Accuracy is assessed using photographic/video evidence covering the relationship between separate parts (fit and gaps), the finish of surfaces and edges, measurements compared with intended measurements and tolerance, and how well off-the-shelf parts and made parts fit together.

Does using CAM or having higher-quality materials automatically increase marks?

No. CAM use does not favour judgement if it is unclear whether the student worked independently. Higher-quality materials do not favour the judgement either, to maintain comparability between centres. Students must document skilled, student-led CAM use to gain credit.
