IB Design Technology IA Criteria Explained: What Examiners Look For
The IB Design Technology Internal Assessment (IA) is a crucial component of your final grade. Understanding the design tech internal assessment criteria is key to achieving a high score. This guide provides a clear breakdown of each criterion, offering practical tips and examples to help you excel. We'll delve into the IB design tech grading rubric and offer insights into how to meet the IB standards effectively.
What is the Design Tech Internal Assessment?
The Design Tech Internal Assessment is a design project where you identify a real-world problem, develop a solution, and create a prototype. It allows you to apply the design process learned throughout the course and demonstrate your understanding of design principles. The IA is assessed internally by your teacher and externally moderated by the IB.

Understanding the Grading Criteria
The Design Tech IA is assessed using five criteria (A-E), each focusing on a different aspect of the design process. Each criterion has a specific mark range, and the total score is out of 33 marks. Understanding how the internal assessment marking works is essential for success.
Detailed Breakdown of Design Tech Internal Assessment Criteria
Criterion A: Empathize (0–9 marks)
What it assesses: This criterion assesses the extent to which you identify and investigate a real user problem or need. It requires thorough research into the design context, identifying an appropriate problem leading to a design opportunity, and understanding user needs and background.
The criteria explanations and markband guidance here are independently written for students; they are not an official IB publication.
Tips for success:
- Choose a problem you are genuinely interested in. This will make the research process more engaging.
- Conduct thorough user research. Use a variety of methods, such as surveys, interviews, and observations, to gather data.
- Clearly define the problem. A well-defined problem will make the rest of the design process easier.
- Example: Instead of simply stating "People need a better way to carry groceries," a strong empathize section would delve into the specific challenges faced by elderly individuals living in urban areas who rely on public transportation, including the weight, bulk, and lack of ergonomic design in existing grocery bags.
Common mistakes to avoid:
- Choosing a problem that is too broad or vague.
- Failing to conduct sufficient user research.
- Not clearly defining the problem.
Criterion B: Defining the Project (0–6 marks)
Tips for success:
- Write a clear and concise design brief. The brief should clearly state the problem, the target user, and the desired outcome.
- Develop detailed design specifications. These specifications should be measurable and achievable.
- Justify your specifications with evidence from your user research.
- Example: A strong design brief might state: "Design and create a portable, lightweight, and ergonomic grocery carrying solution for elderly urban residents who use public transportation. The solution must be able to carry at least 20 pounds of groceries, be easily foldable for storage, and provide comfortable weight distribution to minimize strain on the user's back and shoulders."
Common mistakes to avoid:
- Writing a vague or incomplete design brief.
- Failing to develop detailed design specifications.
- Not justifying your specifications with evidence.
Criterion C: Ideation and Modelling (0–6 marks)
Tips for success:
- Generate a wide range of ideas. Don't be afraid to think outside the box.
- Justify your selection of the final design. Explain why you chose this design over the other options.
- Create prototypes or models to test your design. This will help you identify any potential problems.
- Example: Show sketches of at least 5-7 different grocery bag designs, each with unique features like different handle placements, folding mechanisms, and material choices. Then, build a simple physical prototype of your chosen design using cardboard or fabric to test its basic functionality and ergonomics.
Common mistakes to avoid:
- Not generating enough ideas.
- Failing to justify your selection of the final design.
- Not creating prototypes or models to test your design.
Criterion D: Designing a Solution (0–6 marks)
What it assesses: This criterion assesses the extent to which you develop a detailed final design solution. It requires final design plans (drawings, CAD, schematics) and explanations.
Tips for success:
- Create detailed design plans. Use drawings, CAD, or schematics to clearly communicate your design.
- Explain the key features of your design. Explain how each feature works and why it is important.
- Justify your design choices. Explain why you made the design choices you did.
- Example: Produce detailed CAD drawings of your grocery bag design, showing all dimensions, materials, and construction details. Include exploded views to illustrate how different components fit together. Explain the rationale behind each design choice, such as the selection of a specific fabric for its durability and water resistance.
Common mistakes to avoid:
- Not creating detailed design plans.
- Failing to explain the key features of your design.
- Not justifying your design choices.
Present and Justify the Chosen Solution
Independent revision check: Present the final solution clearly and explain why its features respond to the design goals you established. Use concrete evidence from testing or evaluation instead of relying on unsupported claims.
Tips for success:
- Create a clear and concise presentation. Use visuals to help communicate your design.
- Justify your solution against the design criteria. Explain how your solution meets the requirements of the design brief.
- Be prepared to answer questions about your design.
- Example: Create a professional presentation (PowerPoint, Google Slides, etc.) that showcases your final grocery bag design. Clearly explain how your design meets each of the specifications outlined in your design brief, such as portability, weight capacity, ergonomics, and durability. Include images of your prototype and CAD drawings to support your explanations.
Common mistakes to avoid:
- Not creating a clear and concise presentation.
- Failing to justify your solution against the design criteria.
- Not being prepared to answer questions about your design.
How to Excel in Your Design Tech Internal Assessment
- Start Early: Don't wait until the last minute to start working on your IA.
- Manage Your Time: Break down the IA into smaller tasks and set deadlines for each task.
- Seek Feedback: Ask your teacher for feedback on your work throughout the process.
- Stay Organized: Keep all of your research, sketches, and prototypes organized.
- Review the Criteria: Regularly review the grading criteria to ensure that you are meeting the requirements.
- Be Creative: Don't be afraid to think outside the box and come up with innovative solutions.

Common Mistakes to Avoid
- Procrastinating: Starting the IA too late can lead to rushed work and lower scores.
- Ignoring the Criteria: Not understanding the grading criteria is a recipe for disaster.
- Lack of Research: Insufficient research can lead to a poorly defined problem and an ineffective solution.
- Poor Time Management: Not managing your time effectively can lead to missed deadlines and incomplete work.
- Not Seeking Feedback: Not asking for feedback can lead to missed opportunities for improvement.
