What Is the IB Computer Science Internal Assessment (IA)?

The IB Computer Science Internal Assessment (IA) is a major individual project where students design, develop, and evaluate a software solution to a real-world problem. It accounts for 20% of your final IB Computer Science grade and is a key opportunity to demonstrate your programming and analytical skills.

Key Components of the IB Computer Science IA

Your IA consists of several important sections:

  • Planning: Identify the problem, justify the need for a solution, and state your project’s objectives.
  • Analysis: Gather detailed requirements, constraints, and success criteria from your client or users.
  • Design: Present algorithms, pseudocode, and system diagrams showing how your solution will work.
  • Development: Build the actual program using a suitable programming language.
  • Testing: Conduct thorough testing (unit, integration, system tests) and document results.
  • Evaluation: Reflect on how well your solution meets the requirements, discuss limitations, and suggest improvements.

How to Excel in Your IB Computer Science IA

  1. Choose a manageable project: Pick a problem that’s complex enough to showcase skills but realistic within your timeframe.
  2. Engage with a real client or end-user: This adds authenticity and strengthens your analysis.
  3. Document thoroughly: Keep clear records of your planning, design decisions, and testing procedures.
  4. Demonstrate computational thinking: Use flowcharts, pseudocode, and explain your algorithms.
  5. Test extensively: Show evidence of testing with actual outputs and error handling.
  6. Reflect critically: Discuss what worked, what didn’t, and how your solution could evolve.

Common Mistakes to Avoid in IB Computer Science IA

  • Lack of clear problem definition or client involvement
  • Insufficient or vague requirements
  • Poor documentation of algorithms or system design
  • Limited or no testing evidence
  • Superficial evaluation without critical reflection
  • Overly ambitious projects that can’t be completed on time

Word Count and IA Specifics

The IA report has a maximum word count of 2,000 words. This includes your written sections but excludes code appendices and the bibliography.

Focus your word count on detailed explanations and reflections rather than including large blocks of code.

FAQs About the IB Computer Science IA

Q1: How long should my IA project take?
Plan for several months, as you need time for development, testing, and report writing.

Q2: Can I work with classmates on the IA?
No, the IA is an individual project. Collaboration can be in discussing ideas but the work must be your own.

Q3: What programming languages are allowed?
Any language is accepted as long as you justify your choice and it suits your project.

Q4: Can I include screenshots or code snippets in my IA?
Yes, but keep code in appendices and reference key parts in your report.

Q5: How important is client feedback?
Very important—it strengthens your analysis and evaluation sections.

Q6: What if I encounter major issues during development?
Document challenges honestly in your evaluation and explain how you addressed them.
