IB Computer Science (CS) SL Internal Assessment Example

Clear and appropriate scenario with an identified client and evidence of consultation through meeting references and task records

Well‐justified product rationale linking client pain-points to solution features and IB CS skills

Comprehensive and measurable success criteria covering security, usability, performance, and compatibility

Client consultation lacks full primary evidence (e.g., transcripts) for thoroughness

Rationale would be stronger with explicit comparison to alternative tools or approaches

Success criteria could include quantifiable targets (e.g., page-load time thresholds)

Detailed task record with purposes, outcomes, and links to planning criteria

Comprehensive design overview including schema, user-flow charts, page mock-ups, and function catalogue

Exhaustive unit test plan covering valid, boundary, and error conditions for all major functions

Some ‘Target Completion Date’ fields are blank, weakening timeline credibility

Inconsistent notation in the database schema (primary key symbols) and missing index definitions

Minor typos and commented markers in pseudocode reduce maintainability
