Feedback, Testing, Analysis and Evaluation
Planning fair tests, analysing qualitative and quantitative evidence, and reaching balanced judgements that lead to justified modification.
How to prepare for the GCSE Design and Technology written exam
Move from requirement to evidence, technical principle, comparison and justified decision. Use current board materials separately for the NEA and for full timed-paper rehearsal.
Core concepts
Concept 1
Testing should define the criterion, method, variables, measurement and threshold before evidence is gathered.
Exam cue: Distinguish a result, an inference and an evaluative judgement.
Concept 2
Analysis explains patterns, causes and implications in evidence, while evaluation judges the outcome against criteria and acknowledges limitations.
Exam cue: Use comparative data and uncertainty when deciding whether a criterion is met.
Concept 3
User feedback is one evidence source and should be interpreted alongside performance data, expert knowledge, feasibility and stakeholder differences.
Exam cue: Propose a specific modification and explain the evidence, benefit and possible trade-off.
Risk pitfalls and guardrails
Calling a test successful merely because it was completed.
Guardrail: Do not substitute one board's specialist route or current product claim for the multi-board core, and do not turn written process knowledge into NEA or practical submission material.
Accepting one positive comment as representative evidence.
Guardrail: Do not substitute one board's specialist route or current product claim for the multi-board core, and do not turn written process knowledge into NEA or practical submission material.
Listing strengths and weaknesses without reaching a supported judgement.
Guardrail: Do not substitute one board's specialist route or current product claim for the multi-board core, and do not turn written process knowledge into NEA or practical submission material.
