HKDSE DAT study guide
HKDSE DAT · Work through your exam, one topic at a time.
Design and Applied Technology (DAT) is a Category A senior secondary elective in the Hong Kong Diploma of Secondary Education Examination (HKDSE), administered by the Hong Kong Examinations and Assessment Authority (HKEAA). Category A subjects comprise four core subjects - Chinese Language, English Language, Mathematics and Citizenship and Social Development - plus various elective subjects, and DAT sits within that elective group alongside subjects such as Visual Arts, Information and Communication Technology, and Technology and Living. DAT suits senior secondary candidates who are interested in design processes, materials and manufacturing, technological systems and the relationship between design, innovation and society, and who intend to progress to design, engineering or technology-related study. Assessment follows the published HKDSE assessment framework for the subject, and the HKEAA lists School-based Assessment (SBA) arrangements for Category A subjects, so candidates should expect both public examination components and school-based work as set out in the current framework. Results are reported under standards-referenced reporting: except for Citizenship and Social Development, performance is reported in five levels (1 to 5), with 5 the highest, the best-performing level 5 candidates awarded 5 and the next top group 5 , and attainment below level 1 designated 'Unclassified'. To prepare, read the current assessment framework and curriculum and assessment guide, work through sample papers and samples of candidates' performance, and practise design documentation and analysis rather than memorising content alone. Topics on this exam: Design and Applied Technology (Category A senior secondary elective subject). The HKDSE DAT study guide has 1 section and about 483 words.
01Design and Applied Technology: Process, Specifications and Justification
Design and Applied Technology (DAT) is the Category A senior secondary elective in which the HKDSE tests how candidates apply design thinking and technological principles to real products and systems. Questions typically reward a traceable design process, measurable specifications, justified material and process choices, and evaluation against evidence-not attractive sketching alone. Treat design as an iterative loop: identify a genuine need; write a brief stating user, purpose and constraints; convert it into a product design specification (PDS); generate concepts; develop and prototype; test; evaluate; refine. In answers, name the stage and the decision made.

- Practice questions在設計與應用科技科的設計過程中，以下哪一項最能描述「設計綱要」（design brief）的功能？.
- FlashcardsDesign brief. A short statement of the problem, target user and intended outcome that starts a design project.
- Cheat sheetDesign process cycle: identify problem → research → specify criteria and constraints → generate ideas → develop and model → evaluate → realise.
- Key termsDesign process. An organised sequence of stages such as identifying a need, research, idea generation, development, testing and evaluation that designers follow to turn a problem into a workable solution.
- Study planMap the full DAT syllabus structure into a personal one-page topic tree covering design fundamentals, materials and manufacturing, systems and control, and the design project strand.
- Common mistakesCandidates want to look decisive and jump straight to the product they have already pictured, so the brief reads as a description of the answer rather than a statement of need.
