IBDP Design Technology HL
IB Diploma Programme Design Technology Higher Level is a Group 4 science subject that sits at the intersection of creative design thinking, materials science, engineering principles, and human-centred problem solving. The course challenges students to understand and apply the full design cycle — from identifying user needs and generating ideas, through modelling and prototyping, to final production and critical evaluation — while developing a deep appreciation of the social, ethical, and environmental responsibilities that come with designing for the real world.The HL course is structured around four interconnected units. Unit 1 (Human Factors and Ergonomics) develops students' ability to design for real users, applying anthropometric data, cognitive ergonomics, and user-centred design methodologies. Unit 2 (Resource Management and Sustainable Production) builds expertise in materials science — from traditional metals and polymers to smart materials and nanomaterials — alongside life-cycle assessment, eco-design strategies, and the transition to circular economy models. Unit 3 (Modelling) covers the full spectrum of design communication and modelling, from freehand sketching and technical drawing through CAD/CAM, additive manufacturing, and — at HL — systems and control theory, electronics, and microcontroller programming. Unit 4 (Final Production) addresses manufacturing systems, structural analysis, quality management, testing methodologies, and the transformative impact of Industry 4.0 technologies.HL students additionally prepare for Paper 3, a case study examination requiring sophisticated integration of design knowledge across all units, with particular emphasis on sustainability, innovation strategy, and human-centred evaluation. The 60-hour internal assessment design portfolio demands that HL students demonstrate mastery of the complete design process through an original, independently conceived project.This AccelaStudy domain provides comprehensive preparation across all four assessment objectives — knowledge and understanding (AO1), application and analysis (AO2), synthesis and evaluation (AO3), and design skills (AO4) — with adaptive learning pathways, contrastive concept pairs, and exam-focused practice aligned to the current IB DT syllabus.

Who Should Take This
This course is designed for IB Diploma students studying Design Technology at Higher Level who want structured, adaptive preparation for all three external papers and the internal assessment portfolio. It is ideal for students who are passionate about design, engineering, product development, architecture, or sustainable innovation, and who plan to pursue related fields at university. Students who find themselves strong in creative thinking but want to deepen their technical knowledge — or strong in science but want to develop design communication and evaluation skills — will benefit particularly from this domain's balanced coverage of both dimensions of the IB DT HL course.
