IB Computer Science (CS) SL Internal Assessment Example

You identify a clear real-world client need and keep the project grounded in a specific business context.

Your rationale for choosing Flutter and Firebase is fully justified and consistently linked to the client’s operational requirements.

The success criteria are broad, relevant, and mostly testable, with good decomposition into observable subfeatures.

A few justification points could be sharpened by focusing less on brand-level claims and more on concrete technical benefits.

Some success criteria could be made even more measurable by stating exactly what counts as success in each case.

The design evidence is extensive and coherent, showing structure charts, mock-ups, class and relationship diagrams, flowcharts, pseudocode, and database design.

The task record is detailed and clearly shows the development process over time, from planning through implementation and testing.

The test plan is detailed, well aligned to the requirements, and includes meaningful edge cases.

Some diagrams and terminology could be more consistent and easier to read.

A few parts of the development record would be stronger with more precise evidence of what was tested and how success was verified.
