QCE General Design Units 3 and 4 is the Year 12 sequence assessed across three internal assessments (IAs) and one external assessment (EA). Unit 3 (Designing with empathy) is a human-centred approach to an identified person or group. Unit 4 (Sustainable design) uses a redesigning and circular approach to design that can be supported indefinitely. Both units run on the explore, develop and resolve design process.

This page is the index. Below: every dot-point answer we have for QCE Design in 2026, organised by unit, alongside the structural notes you need to plan study.

Note on syllabus versions: QCAA revises its senior syllabuses periodically, and instrument names and weightings can change between versions. The structure below reflects the current QCAA General Design syllabus. Confirm the exact Unit 3 and Unit 4 topics, instrument names and weightings against the syllabus version your school is teaching.

The QCE Design units in 2026

Units 1 and 2 (Year 11)
The foundation - the design process, design in practice, and explorations of design across needs and contexts. Assessed school-internally and not counted in the ATAR subject result, but assumed knowledge for Year 12.
Unit 3: Designing with empathy
A human-centred approach. Students explore the needs and wants of an identified person or group using empathy methods (interview, observation, immersion), then develop and resolve a design response. Core ideas: human-centred design, the explore-develop-resolve process, ideation and design strategies, and visualisation and communication of proposals.
Unit 4: Sustainable design
Designing for sustainability - products, systems and environments that can be supported indefinitely across economic, social and environmental dimensions. Students use a redesigning approach and circular-economy principles to improve an existing design. Core ideas: sustainable design principles, circular design and life-cycle thinking, the redesigning approach, and evaluation and justification.

The four assessments in Units 3 and 4

The summary below reflects the current QCAA General Design syllabus. Verify against your school's syllabus version.

IA1: Design challenge (20 percent)
A school-based response in which students work through the design process to respond to a design challenge under defined conditions, demonstrating exploring, developing and resolving.
IA2: Project (30 percent)
A school-based design project, typically aligned to Unit 3 designing with empathy, presenting an evidenced design folio that documents empathy research, ideation and a justified resolved proposal.
IA3: Project (25 percent)
A school-based design project, typically aligned to Unit 4 sustainable design, applying a redesigning and circular approach and evaluating the sustainability improvement.
EA: External assessment - examination (25 percent)
A QCAA-set and QCAA-marked examination using extended-response items on unseen stimulus, sat at the end of Unit 4. It rewards application of design thinking, evaluation against criteria, and justification of decisions and trade-offs.

The three internal assessments contribute 75 percent of the subject result and the external assessment contributes 25 percent.

Unit 3: Designing with empathy

Unit 4: Sustainable design

Assessment instruments

IA1: Design challenge

IA1 asks students to work through the design process in response to a challenge under controlled conditions. The marks reward visible exploring (a need understood and criteria written), developing (a genuine range of ideas, visualised and tested) and resolving (a refined proposal evaluated against the criteria). Even under time pressure, show the explore-develop-resolve loop rather than jumping to a single solution.

IA2: Project (Unit 3 designing with empathy)

IA2 is the human-centred design project. Strong folios show real empathy data - interview, observation and immersion findings - converted cleanly into design criteria, a wide and well-documented ideation, and a resolved proposal whose every feature traces back to an identified user need. Justification against the criteria is the climax.

IA3: Project (Unit 4 sustainable design)

IA3 is the sustainable redesign project. Strong folios open with a sharp life-cycle critique of an existing design, frame a focused redesign opportunity, apply circular strategies (design for disassembly, mono-materials, durability, repairability), and evaluate the redesign against sustainability criteria with evidence of a measurable improvement over the original.

EA: External assessment

The EA is the QCAA examination, sat at the end of Unit 4 and worth 25 percent. It uses extended-response items on unseen stimulus and rewards the higher-order skills - applying design thinking, evaluating a design against criteria with evidence, and justifying decisions and trade-offs. Drill the connective language of justification (because, therefore, this is supported by) and practise naming and reasoning through trade-offs, since that is where the top-band marks sit.

Study strategy

QCE Design rewards process fluency and disciplined justification.

  1. Internalise explore-develop-resolve. Every instrument is built on it. Practise running a small design challenge end to end in a single sitting.
  2. Practise empathy-to-criteria. For Unit 3, take a real user, gather expressed, observed and latent needs, and convert them into measurable criteria.
  3. Critique real products with a life-cycle lens. For Unit 4, pick everyday products and diagnose their biggest sustainability impacts, then propose circular redesigns.
  4. Drill evaluation and justification. Tie every decision to a criterion and a need, back each claim with evidence, and name and defend the trade-offs. This is the EA's highest-value skill.

Common questions about Design

How is QCE Design structured in Units 3 and 4?
QCE General Design runs across four units. Units 1 and 2 in Year 11 are assessed school-internally and build the foundation. Units 3 and 4 in Year 12 produce the subject result through three internal assessments and one external assessment. Unit 3 is Designing with empathy - a human-centred approach to the needs and wants of an identified person or group. Unit 4 is Sustainable design - using a redesigning and circular approach to design that can be supported indefinitely. The whole subject runs on the explore, develop and resolve design process.
What are the QCE Design assessment instruments and weightings?
Based on the current QCAA General Design syllabus, the assessment is four instruments. IA1 is a design challenge worth 20 percent. IA2 is a project worth 30 percent. IA3 is a project worth 25 percent. The external assessment is an examination with extended-response items worth 25 percent. The three internal assessments together make up 75 percent and the external assessment makes up 25 percent. Confirm the exact instrument names and weightings against your school's current QCAA syllabus version, as QCAA revises syllabuses periodically.
What is the explore, develop, resolve design process?
It is the iterative, non-linear process at the heart of QCE Design. Explore means understanding the need, gathering empathy data, and writing a design brief and criteria. Develop means generating, visualising and testing many ideas through ideation and prototyping. Resolve means refining the chosen idea, evaluating it against the criteria, and communicating and justifying the final proposal. Designers loop back to earlier phases whenever testing or new information reveals a problem.
What is the difference between Unit 3 and Unit 4 in QCE Design?
Unit 3, Designing with empathy, centres on human-centred design - understanding an identified person or group deeply through interview, observation and immersion, then designing to meet their real needs. Unit 4, Sustainable design, centres on designing for products, systems and environments that can be supported indefinitely, using a redesigning approach and circular-economy principles to cut waste and keep materials in use. Both units use the same explore-develop-resolve process.
How does the QCE Design external examination work?
The external assessment is an examination set and marked by QCAA, sat at the end of Unit 4, contributing 25 percent of the subject result. It uses extended-response items that ask students to apply design thinking, evaluate designs and justify decisions in response to unseen stimulus. The skills it rewards most are evaluation and justification - judging a design against criteria with evidence and defending the trade-offs made. Check the current QCAA syllabus for the exact paper format and time.
How should I study for QCE Design?
Master the explore-develop-resolve process until it is second nature, because every assessment is built on it. For Unit 3, practise gathering and using empathy data and converting it into design criteria. For Unit 4, practise critiquing real products with a life-cycle lens and proposing circular redesigns. Above all, drill evaluation and justification - tying every design decision back to a criterion and a need, and naming and reasoning through trade-offs, which is what the projects and the external examination reward most.
