Introduction: the moment your IA turns into a documentary
There’s a point in almost every IA where you can feel the drift.
You start with a sharp question. You collect evidence. You even build a clean table or graph. Then, somewhere between “In this experiment…” and “The results show…,” the writing becomes a play-by-play. It reads smoothly. It sounds academic. It’s also quietly expensive in marks.
Because an IA isn’t graded for how well you can retell what happened. It’s graded for how well you can think on the page: interpret patterns, justify choices, evaluate limitations, and explain why your evidence matters.
If you suspect your IA is too descriptive, you’re already ahead. The fix is not “write less.” The fix is to make every paragraph pull its weight.
Quick checklist: a fast test for a descriptive IA
Run this quick scan on your IA draft:
-
Does each paragraph answer “so what?” after it answers “what?”
-
Do you explicitly link back to your research question (RQ) or aim in most sections?
-
Is your analysis/evaluation visibly longer than your background?
-
Do you compare your results to expectations, models, or credible sources?
-
Do you name limitations and explain their impact on validity/reliability?
-
Can you point to sentences that include judgement language: “this suggests,” “this implies,” “this is limited because,” “an alternative explanation is…”?
If you’re unsure what examiners actually reward, calibrate your standards using What IB Examiners Look for in a Strong IA. It’s often the quickest way to stop guessing.
Why IB students become descriptive (even smart ones)
Most descriptive IA writing comes from reasonable instincts:
Safety feels like accuracy
Description feels “correct.” You can prove you know the content. Analysis feels like stepping onto thinner ice, because it requires interpretation and judgement.
You’re trying to be thorough
IB students are trained to be careful and complete. But thoroughness in an IA means thorough reasoning, not thorough narration.
The rubric feels abstract
If the criteria live in your head as vague words like “analysis” and “evaluation,” it’s easy to write what you can control: background, method detail, and step-by-step reporting.
A good reset is to read a few IA-focused posts in the RevisionDojo IA tag archive and notice the recurring theme: marks come from meaning, not minutes spent writing.
Description vs analysis: the one-step upgrade that changes everything
Think of description and analysis as two different jobs:
-
Description reports what exists: what you did, what you found, what a concept says.
-
Analysis explains what it means: why it happened, why it matters, and how it answers the RQ.
Example:
-
Descriptive: “The graph shows an increase in the dependent variable as temperature rises.”
-
Analytical: “The upward trend suggests temperature increases the rate, consistent with the model, although the plateau after 40°C implies another limiting factor (for example, saturation or denaturation depending on context).”
That second sentence doesn’t just sound better. It earns more, because it shows interpretation, connection to theory, and awareness of alternatives.

How to avoid being too descriptive in your IA (practical strategies)
Use the “claim -- evidence -- meaning -- link” paragraph pattern
When you draft an IA paragraph, aim for this sequence:
-
Claim: what you think the data/source implies.
-
Evidence: the exact number, quote, trend, or pattern.
-
Meaning: why this evidence supports the claim.
-
Link: how this answers your RQ or affects your conclusion.
If a paragraph ends after the evidence, it’s usually descriptive.
Turn every “what” sentence into a “why” sentence
A simple habit: after any sentence that reports something, add one more that begins with:
-
“This suggests…”
-
“This implies…”
-
“This matters because…”
-
“A limitation here is…”
-
“An alternative explanation is…”
This is not filler. In an IA, it’s the difference between showing and thinking.
Compare against expectations (not just against yourself)
Descriptive writing often isolates results. Analysis compares.
Try comparing your findings to:
-
a theoretical prediction
-
literature values
-
a trend you expected based on the syllabus
-
a competing interpretation
For data-heavy sections, the guide 10 Best Practices to Write Up Data and Results in Your IB IA helps you present evidence in a way that naturally invites analysis.
Write method briefly, then evaluate it like an examiner
Your methodology section in an IA should prove control and replicability, but it should not read like a lab manual.
Instead of narrating every step, prioritize:
-
variables and controls
-
measurement precision/uncertainty
-
sample choice and justification
-
why this method is appropriate for the RQ
Then evaluate: where could bias creep in, and how would it change the results?
Use limitations as a pathway to higher marks
Limitations are not confessions. They are evidence of judgement.
A high-value evaluation sentence has three parts:
-
Limitation: what went wrong or could go wrong.
-
Impact: how it affects validity/reliability.
-
Fix: a realistic improvement that would change the outcome.
This is also a great place to use RevisionDojo’s Grading tools to check whether your evaluation actually maps to criterion language. If you want the moderation angle, read How IA Moderation Works (and How to Protect Your Grade).
Tighten the research question to force analysis
A broad RQ produces broad writing, which often becomes description.
If your IA feels like it’s summarizing a topic instead of investigating a relationship, refine your question using What Makes an IA Research Question Too Broad or Too Narrow. A sharper question makes it easier to interpret, evaluate, and conclude.
A 20-minute rewrite drill to remove description
Use this when your IA draft feels heavy but not insightful:
Step 1: highlight “reporting sentences”
Highlight sentences that only:
-
define concepts
-
narrate steps
-
restate what a graph/table shows
Step 2: add one “marks sentence” after each highlight
Add a sentence that does one of the following:
-
interprets the pattern
-
connects to theory
-
links to the RQ
-
identifies an anomaly
-
evaluates a limitation
Step 3: cut without guilt
If a background paragraph doesn’t help your analysis, delete or compress it. Your IA is not a museum of everything you learned.
If you’re stuck, RevisionDojo’s AI Chat is ideal for asking targeted questions like: “What is the strongest alternative explanation for this trend?” or “Where is my evaluation too vague?” For tool-based support and workflow ideas, see How Can AI Be Used to Improve My IA Drafts and Feedback Process.
Conclusion: make your IA an argument, not a record
A descriptive IA is usually written by a careful student trying to do the right thing. The upgrade is learning where marks actually live: interpretation, evaluation, and clear links back to the research question.
Trim the documentary. Keep the evidence. Then do the examiner’s favorite thing for them: explain what it means.
When you want a calm system for that shift, RevisionDojo is built for it: use the Coursework Library to see what strong IA structure looks like, the Grading tools to prioritize high-impact edits, AI Chat to unblock analysis, and your exam toolkit (Questionbank, Study Notes, Flashcards, Mock Exams, Predicted Papers, Tutors) to keep coursework from stealing exam momentum. Your IA doesn’t need more words. It needs more thinking per word.
