GCSE Design and Technology
Learners type short and extended answers in an on-screen examination. In a 40 hour design project worth 70% they write a design brief and specification, annotate and justify ideas, and evaluate their prototype using feedback from users. Numeracy is practical and constant: accurate measuring and marking out within tolerances in every pathway, costing and material estimates in Fashion and Textiles, and formula-based mechanical and electronic calculations in Engineering Design. The single biggest thing Key Stage 3 should build is precise measuring in millimetres against a stated tolerance, followed by a written evaluation that uses test results and user comments as evidence.

Good to know
- Unit 1 is typed on screen, not handwritten: "Digital examination: 1 hour 30 minutes" (Summary of assessment, page 4).
- The specification does not mention marks for spelling, punctuation and grammar. The four assessment objectives cover knowledge, application, developing designs and analysing and evaluating, and "The Assessment Pack will include all detailed information relating to assessment." (Assessment, page 43).
- The specification does not say whether a calculator is allowed in the on-screen examination, although Engineering Design learners must "calculate ohms law" (Unit 1, 1.1.9, page 17). Check the Assessment Pack.
- Formula-based calculations are for one pathway only: "This area of study is relevant to learners that have chosen Engineering Design as their pathway." (Unit 1, 1.1(a), page 14). Costing from standard fabric widths sits in Fashion and Textiles (Unit 1, 1.1.18, page 23).
- The design project is "Non-examination assessment: Approximately 40 hours", worth 70% and 100 marks (page 4). AO4, analyse and evaluate, is 20% of the qualification and is assessed only in Unit 2 (page 43).
- Written notes, presentations and mathematical modelling are listed "for example" (Unit 2, 2.1.4, pages 34 to 35), which the specification says "indicates that the specified content is for guidance only" (page 8). No word limits are stated.
Links with other qualifications
Ohm's law and moments overlap with The Sciences, gear ratios, scale drawing and tolerances with Mathematics and Numeracy, and product analysis and evaluative writing with English Language and Literature, so shared methods and vocabulary would help pupils.
