IB Design
Technology,
from concept to product.
IB DP Design Technology HL and SL — human factors, materials science, sustainable design and a full design-and-make IA project. The IB subject for future product designers, architects and engineers.
The IB's product design subject. Human factors, materials, sustainability and a real design-and-make project — ideal for architecture, industrial design and engineering pathways.
DT bridges design thinking and engineering.
IB Design Technology is the Group 4 subject for students interested in how products are conceived, designed, prototyped and manufactured. It blends scientific knowledge (materials, energy, sustainability) with design thinking (human factors, ergonomics, aesthetics, user-centred design).
The IA design project
The IA requires students to identify a real design need, develop a solution through an iterative design cycle, prototype it, test it and evaluate it. At HL, the IA is worth 40% of the final grade — the highest IA weighting in the entire IB. This makes IA coaching essential.
HL vs SL
HL adds CAD/CAM, advanced materials, user-centred design depth and the extended IA weighting. SL covers core design thinking and materials science at a lighter depth.
The full content we cover.
Every Times Edu Design Technology mentor maps lessons directly to the official syllabus — nothing on the exam is a surprise.
Human Factors & Ergonomics
Anthropometrics, psychological factors, user-centred design.
Resource Management
Sustainability, energy, environmental impact, LCA.
Modelling
Prototyping, CAD, scale models, iterative design.
Raw Materials & Manufacturing
Material properties, production techniques, quality control.
Innovation & Markets
Market research, invention vs innovation, intellectual property.
User-Centred Design
Advanced UCD methods, personas, usability testing.
Sustainability & Green Design
Cradle-to-cradle, biomimicry, circular economy.
Design Project
Full design cycle: identify → develop → create → evaluate.
Every paper and assessment, mapped.
Knowing the format is half the battle. Here is the full breakdown.
Short Answer
Core content short-answer and data-response questions.
Structured
Extended structured questions requiring design application.
Case Study (HL)
Pre-seen case study on a design scenario — HL only.
Design Project
Individual design project from brief to prototype and evaluation.
Why even strong students lose marks here.
Three traps we see most often — every one is fixable with focused coaching.
Skipping user research
The IA marks user engagement heavily. Students who design a product without talking to actual users cap at grade 4.
Weak materials knowledge
Paper 2 tests specific material properties — tensile strength, thermal conductivity, biodegradability. Vague answers lose all marks.
No design iteration
The IA rewards iterative development. Students who build one prototype without testing and improving cap at grade 5.
From diagnostic to final grade.
My DT project went from a vague idea to a fully prototyped ergonomic desk accessory with user testing data. The IA scored 34/36. Times Edu coached every step.
What families always ask.
Is DT a science or an art?
Officially Group 4 (sciences). It has scientific content (materials, energy) but the design process is closer to art and engineering. Universities accept it as either.
Is DT respected by universities?
Yes — especially for product design, architecture, industrial design and engineering programmes. It demonstrates both creative and analytical thinking.
How important is the IA really?
Critical — 40% of the final grade at both HL and SL. A strong IA can single-handedly carry the grade.
Does my child need to build a physical product?
Not necessarily — digital products, app prototypes and CAD models are also accepted. We advise on the best format during the diagnostic.
