IB Computer Science IA Guide | With 20 IB CS IA Ideas

The Internal Assessment (IA) is an essential component of the IB Computer Science course. It allows you to demonstrate your understanding of key concepts and apply your programming skills to solve real-world problems. The IA should consist of a written report and a working program that addresses a specific problem or task.

Selecting a Topic

Choosing the right topic is crucial for a successful IA. Consider the following tips:

  • Interest: Select a topic that genuinely interests you. This will keep you motivated throughout the process.

  • Feasibility: Ensure that the chosen problem is manageable within the given time frame and resources.

  • Scope: Define the scope of your project clearly. Avoid overly ambitious ideas that may lead to incomplete implementations.

IA Structure

Your IA should include the following sections:

  • Introduction: Briefly introduce the problem or task you aim to solve.

  • Analysis: Analyze the problem and discuss the requirements and constraints.

  • Design: Outline your solution, including algorithms and data structures.

  • Implementation: Provide the code for your solution. This should be well-commented and organized.

  • Testing and Validation: Explain how you tested your program and validate its correctness.

  • Conclusion: Summarize your findings, reflect on challenges faced, and suggest possible improvements.
