WJEC GCSE Design and Technology Unit 2 design and make task (NEA): an overview of the iterative process and assessment
A concise overview guide to the WJEC GCSE Design and Technology Unit 2 non-exam assessment. Covers the design and make task, the contextual challenges, the iterative stages from investigation to evaluation, how the work is internally assessed and externally moderated, and how it links to the designing principles.

What Unit 2 is
Unit 2 is the non-exam assessment (NEA), a practical design and make task worth 50 percent of WJEC GCSE Design and Technology. Unlike the technical principles you revise for Unit 1, this unit is something you do: you design and make a prototype that solves a real problem, set within a contextual challenge released by WJEC, in your endorsed area (Engineering Design, Fashion and Textiles, or Product Design). It is internally assessed by your teacher and externally moderated by WJEC. This guide is a concise overview; the detailed designing skills live on their own dot-point pages.
The contextual challenge
WJEC releases broad contextual challenges that set a starting context rather than a fixed product. You choose and refine a real problem within one, identifying a genuine user and need. This freedom means two students with the same context can make very different products, so the early decision about which problem to tackle, and for whom, shapes the whole project.
The iterative process
The task follows an iterative design process, looping back to refine as you learn, rather than a single straight line. The main stages are:
- Investigate the problem, the user, the context and the work of others, then write a design brief and a measurable specification.
- Generate and develop a range of ideas, using sketching, modelling and CAD, and refine the best against the specification.
- Plan and manufacture the prototype, selecting suitable materials and processes and working safely and accurately.
- Test and evaluate the outcome against the specification and with the user, then suggest improvements.
Throughout, you test and refine, because finding problems early makes them cheap to fix.
How it is assessed
The NEA is judged on the whole process, not just the finished prototype. The marks reward:
- the quality and relevance of investigation;
- the range and development of design ideas;
- the skill and accuracy of making the prototype;
- the depth of testing and evaluation against the specification and user.
The work is presented as a concise design portfolio alongside the made outcome. Because it is internally assessed and externally moderated, the standard is kept consistent across centres.
How the NEA links to the course
The NEA is where you apply the designing and making principles and the technical principles from Unit 1. Investigation and specification writing, communication through sketches and CAD, sustainability and the 6 Rs, ergonomics and anthropometrics, and the choice of materials, processes and scales all feed directly into the task. In other words, the knowledge you revise for the written exam is the toolkit you use to make good decisions in the practical project.
