IB Computer Science IA source code requirements
IB Computer Science IA Source Checker
Computer Science IA products must be student-developed. Libraries and references can be cited, but unmodified templates, copied exemplar databases, or significant copied code are high-risk unless substantially transformed and acknowledged.

Computer Science IA source check
Marksy reads the links or source notes you provide, applies the selected IB assessment profile, and only stops for clarification when the score depends on it.

Source rules
What usually works for Computer Science IA
Usually strong
- Official library documentation, API docs, algorithm references, and cited code snippets used narrowly.
- Client/user evidence, testing data, and design documentation produced by the student.
- Open-source libraries when licensing and use are acknowledged.
Needs review
- Starter templates that define most of the product structure.
- AI-generated code blocks pasted without understanding or attribution.
- Tutorial apps that match the final product too closely.
Avoid or replace
- Unmodified exemplar databases or web templates.
- Copied code that forms the core functionality.
- Assets or code with unclear license/provenance.
Examples: strong, risky, weak
Strong
Official API documentation plus student-authored code, user interview notes, and testing evidence.
Review
A Stack Overflow snippet used for one utility function with attribution and modification.
Weak
A downloaded app template with only colors and labels changed.
Where to find better Computer Science IA sources
If your current source gets a warning, do not just add more websites. Use searches that match the assessment rule and replace weak evidence with sources that can actually carry analysis.
Search queries to try
Replacement moves
Replace unmodified exemplar databases or web templates. with official library documentation, api docs, algorithm references, and cited code snippets used narrowly..
Use starter templates that define most of the product structure. only as context unless your teacher confirms they can carry evidence.
Add one source that gives direct evidence for the IA, not just general background.
