A week into the IB Extended Essay, most students don’t quit because they “can’t write 4,000 words.” They quit because they can’t decide what the essay is actually about.
It starts innocently: a topic you like, a few tabs open, maybe a quote you feel smart for saving. Then your notes multiply, your argument blurs, and your supervisor says the sentence you’ll hear ten more times: “Narrow it.”
A strong IB Extended Essay lives or dies on one thing: a research question that’s clear enough to guide every paragraph, but deep enough to reward analysis. Here are eight proven tips to craft a question that keeps you focused, helps you earn marks, and still feels like your curiosity.
A quick checklist for a high-scoring IB Extended Essay question
Before you fall in love with your wording, run this checklist:
-
Is the IB Extended Essay question one sentence and unambiguous?
-
Can you answer it with analysis (not summary)?
-
Is it feasible with your time, access to sources/data, and word limit?
-
Does it clearly match your registered subject’s method?
-
Can you picture 3–5 body sections that directly answer it?
If you want a criteria-aligned overview of how the whole project fits together, keep RevisionDojo’s EE Guides hub open while you plan.
Tip 1: Start with a topic you can live with for 40 hours
The best IB Extended Essay research questions often come from something small that keeps nagging at you. A single scene in a novel. A local policy you disagree with. A lab result that surprised you.
Choose a topic you’d still care about when you’re tired. Interest is not “extra” -- it’s how you keep going when the research gets messy.
If you’re still choosing a direction, use 10 Powerful Steps to Choose an Extended Essay Topic to shortlist ideas that are actually workable.
Tip 2: Turn the topic into a question with an edge
A topic is a container. A research question is a blade.
Bad: “Technology in education.”
Better: “To what extent has the introduction of X changed Y for Z group in (place/time)?”
Your IB Extended Essay should be able to disagree with itself. If your question has only one obvious answer, you’ll write 4,000 words of explanation instead of argument.
Tip 3: Use command terms that force analysis
Command terms are like steering wheels. They don’t just shape your title -- they shape your thinking.
High-analysis stems for an IB Extended Essay include:
-
To what extent (invites judgement)
-
How significant (forces weighing factors)
-
In what ways (requires patterns + interpretation)
-
Compare (creates structure automatically)
-
Evaluate (demands criteria)
Avoid verbs like describe or outline unless your subject guide explicitly expects them.
Tip 4: Build in boundaries (time, place, text, variables)
Most “too broad” research questions are missing boundaries.
A practical rule: your IB Extended Essay question should limit at least two dimensions, such as:
-
Time period (2010–2020, post-war, pre-2008)
-
Place (one city, one country, one region)
-
Text selection (one novel, one poet, two ads)
-
Population (one age group, one school, one sample)
-
Variables (one independent and one dependent)
When in doubt, narrow further than you feel comfortable. You can always widen slightly later. The opposite is harder.

Tip 5: Stress-test feasibility before you commit
A beautiful IB Extended Essay question that you can’t research is just a nice sentence.
Do a 30-minute feasibility test:
-
Find 5 credible sources quickly (or 2 strong datasets, or a workable experimental method).
-
Write 3 possible answers to your question.
-
List what evidence would support each answer.
If you can’t find sources that match your boundaries, change the question now, not after you draft your introduction.
If sourcing is your bottleneck, use What Are the Best Sources for IB Extended Essay Research? to build a smarter evidence plan.
Tip 6: Make sure the question matches your subject’s method
Your IB Extended Essay question must behave like the subject you registered.
-
Economics wants theory + data, not vibes.
-
History wants focused evidence-based argument, not personal opinions.
-
Sciences want a clear method, variables, and data handling.
-
Literature wants close analysis, not plot summary.
When students lose marks, it’s often because their question belongs to a different subject.

Tip 7: Use supervisor feedback, but bring options (not chaos)
Supervisors are most helpful when you don’t ask, “Is this good?” but instead ask, “Which of these two is more assessable?”
Bring two versions:
-
Version A: narrower, more specific
-
Version B: slightly broader, more flexible
Then ask what will score better on focus and method in your IB Extended Essay.
Also remember: one of the calmest ways to make supervisor meetings productive is to arrive with a one-page plan (question, scope, evidence, method). That document becomes your anchor when you feel tempted to restart.
Tip 8: Revise the question as you research (but don’t endlessly restart)
A good IB Extended Essay question can evolve. The trick is to revise with purpose, not panic.
Revise when:
-
You discover the key sources are unavailable.
-
Your method doesn’t produce usable evidence.
-
Your scope is clearly too wide for 4,000 words.
Don’t revise just because you found a new interesting angle. Park those ideas in a “Later” document. Finish the essay you can actually complete.

A simple template you can copy
Use this to draft a first-pass IB Extended Essay research question:
To what extent does (cause/framework/technique) affect (outcome/meaning/behavior) in (specific case study) during (time period) when measured/analysed using (method/criteria)?
You won’t keep every clause. But starting “over-specific” is how you land on “just right.”
Closing: make the question do the heavy lifting
When your IB Extended Essay research question is right, everything downstream gets lighter: reading becomes targeted, writing becomes structured, and your argument starts to feel inevitable rather than improvised.
If you want the fastest path from “interesting idea” to “assessable question,” build your system with RevisionDojo: sharpen concepts with Study Notes, stress-test wording with AI Chat, calibrate standards with the Coursework Library, and keep exam readiness steady with Questionbank, Mock Exams, and Predicted Papers. Your research question isn’t just the start of the essay -- it’s the engine that keeps the whole IB Extended Essay moving.
