Your IB extended essay is due, and you have not written a single word yet. Not because you are behind, but because you do not know where to start. An outline fixes that. Below is a step-by-step structure for your EE outline, mapped to the IB's own section requirements, with a template you can fill in before you open a blank document.

Why an Outline Matters for the EE Specifically
For a standard school essay, skipping the outline is a minor risk. For a 4,000-word IB research paper with a supervisor, a viva voce, and formal assessment criteria, it is a serious one.

Here is what the outline actually does for you:
- It locks in your research question before you waste time. The EE lives or dies on a focused, arguable research question. Your outline forces you to commit to one early and to test whether you actually have enough to say about it.
- It shows you where your evidence is thin. When you map your supporting points in the outline, gaps become obvious before you have written anything. It is much easier to fix a weak argument at the outline stage than to discover it 3,000 words in.
- It keeps your supervisor on side. Most EE supervisors want to see a working outline at the first check-in. A structured outline signals that you know what you are doing.
The IB Extended Essay Structure: What Your Outline Needs to Cover
The IB has specific structural requirements for the EE. Your outline should map to these sections, not just generic "introduction/body/conclusion" headings. Here is the required structure and the approximate word allocation most high-scoring EEs use:
Section | IB Requirement | Recommended Words |
Title page | Yes (subject, research question, session, word count) | n/a |
Table of contents | Yes | n/a |
Introduction | Yes | 300–500 words |
Body | Yes, multiple sections with subheadings | 2,500–3,000 words |
Conclusion | Yes | 300–500 words |
References / Bibliography | Yes | n/a |
Appendices | Optional | n/a |
The research question itself is not a section. It appears on the title page and is restated in the introduction, but it governs every section. If a body paragraph does not directly advance your answer to the research question, it does not belong in the essay.
One formatting question that comes up often: the IB removed the abstract requirement from the EE in 2018, so you do not need one.
Components of an Extended Essay Outline
Introduction
Your introduction has three jobs: establish context, state your research question, and preview your argument.
Background information: One to two paragraphs that give the reader enough context to understand why your research question matters. This is not a history of everything. It is the specific context that makes your question interesting and arguable. Research question: State it clearly. The IB requires it on your title page; your introduction should restate it and briefly explain why it is worth investigating. Thesis/Line of argument: One to three sentences that tell the reader what your essay will argue and how. This is not a summary of your findings. It is your position. You are telling the reader where you are going before they follow you there.
Body
The body is where most outlines fall apart, because students treat it as one block instead of a sequence of connected arguments. Structure it as distinct sections, each with its own claim, evidence, and analysis.
Section structure: Each body section should do one thing: advance one part of your overall argument. Give each section a working title in your outline. Not a topic label like "History of X" but an argumentative one like "Why X explains Y better than Z does."
Topic sentences: The first sentence of each section states the section's claim. Write these in your outline before you write the section. If you cannot write a one-sentence claim for a section, you do not yet know what that section is arguing.
Supporting evidence: For each section, note the specific evidence you plan to use: author, source, and the point it supports. If you cannot fill this in at the outline stage, you need more research before you start writing.
Analysis: Evidence does not argue for itself. Note in your outline how you will interpret each piece of evidence and connect it back to your research question. This is what distinguishes an EE from a report.
Conclusion
The conclusion does not introduce new information. It does three things:
Restates the thesis in different words, reflecting what the body actually demonstrated.
Summarises the argument with a concise account of how your body sections are built toward your answer.
Addresses implications by explaining what your findings mean beyond the essay itself. What questions remain open? What would further research look like? This is where high-scoring conclusions distinguish themselves.
References and Bibliography
This is not a section to write, but it is a section to plan. Note your citation style (MLA, Chicago, or whatever your subject requires) in your outline and keep a running source list from the first day of research. Retrofitting a bibliography after you have finished writing is significantly more painful than maintaining it as you go.
If you have a research question and a rough sense of your subject, but you are not confident that the structure you have mapped will hold up to 4,000 words, extended essay writing assistance from our team can work through the outline with you before you commit to writing.

I.INTRODUCTION (300-500 words)
- Background/context
- Research question (restated)
- Thesis/line of argument
II. BODY SECTION 1: [Argumentative heading] (~600-750 words)
- Topic sentence/claim
- Evidence: [Source, key point]
- Analysis: [How this advances the research question]
III. BODY SECTION 2: [Argumentative heading] (~600-750 words)

Extended Essay Outline Examples
The template above applies across all IB subjects. What changes is how you fill it in: the nature of the evidence, the type of argument, and the citation style. Below are three worked examples across different subjects, so you can see the same structure applied in practice.
Example 1: History EE
Title: The Role of Economic Sanctions in Apartheid South Africa's Decline
Research Question: To what extent did international economic sanctions contribute to the end of apartheid in South Africa between 1985 and 1994?
Subject: History
Citation style: Chicago
I. INTRODUCTION
- Context: apartheid system, international pressure from the 1960s onward
- Research question restated
- Thesis: Sanctions were a necessary but not sufficient cause. Their effect was amplified by internal resistance; neither alone was decisive.
II. THE SCOPE AND STRUCTURE OF SANCTIONS (1985-1989)
- Claim: Sanctions were more comprehensive post-1985 than commonly assumed, targeting financial, trade, and cultural sectors
- Evidence: Commonwealth Accord 1985, US Comprehensive Anti-Apartheid Act 1986 (Massie, Loosing the Bonds, 1997)
- Analysis: Establishes the actual economic pressure applied as the baseline for measuring impact
III. ECONOMIC IMPACT ON THE SOUTH AFRICAN STATE
- Claim: Sanctions created measurable fiscal stress, reducing the government's capacity to fund enforcement
- Evidence: GDP contraction data, Reserve Bank reports, Lipton (1988) analysis
- Analysis: Distinguishes economic stress from political will and links to the research question
IV. INTERNAL RESISTANCE AND THE SANCTIONS RELATIONSHIP
- Claim: Sanctions were most effective when coordinated with ANC internal campaigns. Neither worked independently.
- Evidence: ANC strategy documents, Mandela correspondence, de Klerk memoirs
- Analysis: Tests the "necessary but not sufficient" thesis directly
V. THE LIMITS OF SANCTIONS: COUNTERARGUMENTS
- Claim: Key trade partners continued partial trade; sanctions had gaps that limited their impact
- Evidence: Trade statistics, Thatcher government position (Renwick 2014)
- Analysis: Acknowledges limitations, required for balanced argument per IB Criterion C
VI. CONCLUSION
- Thesis restated: Sanctions were a necessary accelerant, not a sole cause. The evidence supports a multi-causal account.
- Summary of how each body section built the argument
- Implications: Raises questions about sanctions efficacy in other authoritarian contexts and the limits of the case study
Example 2: Psychology EE
Title: Social Media Use and Adolescent Self-Esteem
Research Question: To what extent does passive social media consumption negatively affect self-esteem in adolescents aged 13-17?
Subject: Psychology
Citation style: APA
I. INTRODUCTION II. DEFINING PASSIVE VS ACTIVE SOCIAL MEDIA USE III. SOCIAL COMPARISON THEORY AS THE MECHANISM IV. MODERATING VARIABLES: WHO IS MOST AFFECTED V. LIMITATIONS OF THE EVIDENCE BASE VI. CONCLUSION
Example 3: Economics EE
Title: Carbon Pricing and Emissions Reduction in the European Union
Research Question: To what extent has the EU Emissions Trading System reduced carbon dioxide emissions in the European power sector between 2005 and 2020?
Subject: Economics
Citation style: MLA
I. INTRODUCTION
- Context: EU climate targets, ETS design and history since 2005
- Research question restated
- Thesis: The ETS reduced emissions in the power sector but underperformed during Phase 1 and 2 due to over-allocation of permits. Phase 3 reforms significantly improved effectiveness.
II. HOW THE ETS WORKS: MECHANISM AND DESIGN
- Claim: Cap-and-trade design creates a price signal that should incentivize abatement, but only if the cap is binding
- Evidence: European Commission ETS design documentation, Ellerman & Buchner (2007)
- Analysis: Establishes the theoretical basis for expecting emissions reductions and the conditions under which it fails
III. PHASE 1 AND 2 PERFORMANCE (2005-2012): WHY IT UNDERDELIVERED
- Claim: Over-allocation of permits drove the carbon price to near zero; the ETS had no binding effect during these phases
- Evidence: Carbon price data 2005-2012, Ellerman et al. (2010), European Environment Agency reports
- Analysis: Explains the gap between design intent and outcome and links to the thesis's phase-specific argument
IV. PHASE 3 REFORMS AND IMPROVED OUTCOMES (2013-2020)
- Claim: Auctioning replaced free allocation; the Market Stability Reserve tightened supply; emissions fell measurably
- Evidence: EEA emissions data, Betz & Sato (2006), Marcu et al. (2017)
- Analysis: Demonstrates the reform-outcome relationship and tests the causal claim in the thesis
V. ALTERNATIVE EXPLANATIONS: ECONOMIC DOWNTURN AND GAS PRICES
- Claim: Part of the emissions reduction is attributable to the 2008 recession and the gas-for-coal switch, not the ETS alone
- Evidence: IEA energy mix data, Eurostat GDP contraction figures
- Analysis: Isolates the ETS effect from confounding variables, required for an honest causal argument
VI. CONCLUSION
- Thesis restated: ETS reduced emissions, but effectiveness was phase-dependent; Phase 3 reforms were decisive
- Summary of the argument
- Implications: Lessons for carbon pricing design in other jurisdictions where binding caps and stable price signals matter

Steps for Writing Your Extended Essay Outline
Step 1: Define Your Research Question
Before you touch the outline, you need a research question that is specific, arguable, and answerable in 4,000 words. This is harder than it sounds.
A research question that is too broad ("How did World War II affect Europe?") cannot be argued in an EE. It can only be summarised. A question that is too narrow ("What was Churchill's exact position on rationing in the winter of 1941?") may not have enough source material to sustain a 4,000-word argument.
Test your research question against three criteria: Can you take a position on it? Can someone disagree with your position? Does answering it require genuine research and analysis, not just reporting? If yes to all three, you have a workable question. If not, keep narrowing.
Talk to your supervisor before finalizing it. The research question is the hardest revision to make after you have started writing. If you have not settled on a subject yet, the extended essay topics page organizes research question ideas by IB subject group so you can find a direction before you build the outline.
Step 2: Research the Topic
Research for the EE means primary and secondary sources, not just Google. Depending on your subject, this might include academic journals, archived documents, data sets, literary texts, scientific studies, or interviews.
As you research, keep a working bibliography from day one. Note the author, title, date, and the specific point each source gives you. Organize notes by potential body section so that when you sit down to fill in your outline, you can see immediately which sections have strong evidence and which need more work.
Step 3: Identify Your Supporting Points and Evidence
With your research question set and your research gathered, map your supporting points. These become the argumentative headings of your body sections.
Each supporting point should do one of these things: establish a premise your argument depends on, provide direct evidence for your thesis, address a counter-argument, or draw out an implication. If a point does not do one of these things, it probably does not belong in the essay.
Step 4: Organize Your Outline
With your sections identified, arrange them in a logical sequence. This does not mean chronological order by default. It means the sequence that builds your argument most clearly.
Ask yourself: Does section 3 depend on section 2? Does the reader need to understand point A before point B makes sense? A well-ordered body does not just cover ground. Each section sets up the next one.
Step 5: Revise and Get Supervisor Sign-Off
Read your outline from start to finish as if you have never seen your research question before. Does the sequence of body sections actually build to the conclusion you are claiming? Are there gaps where the argument jumps without the evidence to support the leap?
Then give it to your supervisor. Their job is to catch these problems at the outline stage, not after you have written 3,000 words. Take their feedback seriously. The outline is significantly easier to restructure than the essay.
You have the structure. The harder part for most IB students is turning a clean outline into 4,000 words of original, sourced argument while managing the rest of the diploma. If you would rather hand the outline to us, our writers produce complete, extended essays that meet IB format requirements, with enough lead time for supervisor review.
Tips for an Effective IB Extended Essay Outline
These principles apply across the IB Diploma's types of essays, but they matter most in the EE because the stakes of a poorly structured argument are highest at 4,000 words.
Start with the Research Question, Not the Topic
A topic ("economics of apartheid") is not an outline-ready starting point. A research question ("to what extent did sanctions contribute to apartheid's end?") gives you the argument you need to structure.
Write Argumentative Section Headings, Not Topic Labels
"The Role of Sanctions" tells you what the section is about. "Why Sanctions Alone Were Insufficient" tells you what the section argues. The second version is a better outline entry because it forces you to commit to a position before you write.
Map your Word Count Before you Start
4,000 words across six sections is not evenly distributed. Allocate deliberately. Body sections typically carry 600–750 words each. Introduction and conclusion carry 300–500 each. If your outline implies a 1,500-word introduction, something has gone wrong.
Build your Counter-Argument Section from the Start
Every strong EE addresses an opposing view or a limitation of its own argument. IB Criterion C (critical thinking) specifically rewards this. Do not treat the counter-argument as an afterthought. Give it a dedicated body section in your outline and assign it the same evidence-mapping rigor as your main points.
Use Criteria B and C as a Filter on Every Body Section
Criterion B assesses knowledge and understanding: does each section demonstrate that you understand the subject matter at an appropriate level? Criterion C assesses critical thinking: does each section do more than report evidence, actively interpreting it and connecting it to your research question? Run every body section heading through both filters before you write. If a section is pure reporting with no analytical move, it will cost you on Criterion C.
Share your Outline with your Supervisor Before you Write, Not After
Your supervisor has read EEs before. They will spot in five minutes whether your research question is too broad, whether your body sections are argumentative or just topical, and whether your evidence mapping has gaps. That conversation costs you nothing at the outline stage. At 3,000 words in, the same conversation costs you a significant rewrite.
You have the framework. Now comes writing it. If you want a complete draft you can actually work from, formatted to IB requirements with a bibliography and delivered in time for supervisor review, tell us your subject, research question, and deadline. CollegeEssay.org's extended essay team handles the rest.
Frequently Asked Questions
How long should an extended essay outline be?
An extended essay outline does not have a word count requirement. It should be detailed enough that every body section has a working title, a one-sentence claim, and at least one source noted against it. Most students produce one to two pages.
When should I write my extended essay outline?
Before you write anything else. The extended essay outline comes after you have a confirmed research question and enough research to identify your supporting points, but before you open a blank document for the essay itself.
How many sections should an extended essay outline have?
Most extended essay outlines have four to six body sections sitting between the introduction and conclusion. The right number depends on how many distinct argumentative claims your research question requires, not on a fixed formula.
Does my extended essay outline need supervisor approval?
The IB does not formally require a supervisor's sign-off on your extended essay outline, but sharing it at your first meeting is strongly recommended. Supervisors catch structural problems at the outline stage far more easily than after you have started writing.
Can I change my extended essay outline after I start writing?
Yes. An extended essay outline is a working document, not a contract. If your research takes you in a direction your original outline did not anticipate, revise the outline before you continue writing rather than forcing new material into a structure it does not fit.
