How to Write a Strong IB Internal Assessment (IA) in Any Subject

🧩 1. Start with a Focused Research Question

Avoid broad or vague phrasing.

✅ Example: "How does caffeine affect plant growth?" → too vague

✅ Better: "To what extent does caffeine concentration affect root length in Phaseolus vulgaris?"

📊 2. Link Back to the Syllabus

Examiners love clear connections to the subject's key concepts.

Drop one or two specific syllabus terms naturally in your introduction and analysis.

🧠 3. Explain, Don't Describe

IB rewards analysis.

Instead of saying "the trend increases," say "the rate of increase suggests a proportional relationship between variables."

💬 4. Reflect in Your Conclusion

Include evaluation: What worked, what didn't, and how you'd improve the method.

This shows maturity of thought — a core IB criterion.
