Introduction
The IB Internal Assessment (IA) is one of the most important parts of the Diploma Programme. It counts for 20–30% of your final grade in most subjects and allows you to explore a topic of personal interest. But while the IA is an opportunity, it’s also where many students lose marks due to common mistakes.
This guide offers a troubleshooting approach to IB Internal Assessments mistakes, showing where students often go wrong and how to fix those issues before submission.
Why Students Struggle With Internal Assessments
Internal Assessments are challenging because they combine:
- Independent research or experimentation.
- Data collection and analysis.
- Structured writing in line with IB criteria.
- Reflection and evaluation.
Unlike exams, where you can cram facts, the IA requires careful planning, discipline, and attention to detail.
Common Mistake #1: Poor Research Question
The foundation of your IA is the research question. A weak or vague question leads to confusion and poor analysis.
Examples of weak questions:

- “How do acids react with metals?” (too simple)
Fix:
- Narrow your focus and make the question measurable.
- Example: “What is the effect of pH on the rate of germination in mung beans?”
