What is the Extended Essay (EE)? Get a complete overview of this mandatory 4,000-word research paper in the IB Diploma Programme core.

The Ultimate Guide to the IB Extended Essay (EE)

So, you've heard about the Extended Essay—the "EE". That massive 4,000-word research project is a core part of the IB Diploma. Before you start stressing about the word count, let's reframe this. The EE isn't just a long essay; it's your chance to become a genuine expert on a topic you're passionate about. It's your first real taste of university-level research and, honestly, one of the most rewarding challenges you'll face in the IB.

We're here to break down this beast of a project into manageable, understandable steps. Let's get started.

Why the EE is Your Secret Weapon for University

Before diving into the "what" and "how", let's talk about the "why". The EE is much more than a box-ticking exercise. It’s a transformative experience designed to give you a serious edge.

  • It's a University Audition: The skills you build—independent research, critical analysis, academic writing—are precisely what professors look for. Nailing the EE proves you're ready for undergraduate-level work.
  • Explore What You Genuinely Love: This is your chance to go "off-piste" from the syllabus. Fascinated by the economics of K-Pop? The physics of a perfect golf swing? The historical accuracy of a video game? The EE is your playground.
  • Boost Your IB Score: Let's not forget the points! Your EE grade, combined with your TOK grade, can contribute up to 3 bonus points to your final Diploma score. That can be the difference-maker.
  • Supercharge Your Applications: A well-executed EE on a topic related to your desired university course is pure gold for your personal statement and interviews. It screams passion and academic dedication.

Anatomy of a 4,000-Word Essay: The Structure

4,000 words sounds like a lot, but when you break it down into a clear structure, it becomes much less intimidating. Every strong EE follows this blueprint:

  1. Title Page: The formal front door to your essay. It must include your title, your specific research question, the IB subject, and your final word count. Do not include your name, candidate code, or school name.
  2. Contents Page: A clear and organized roadmap for your examiner, listing all sections and their page numbers.
  3. Introduction (approx. 300-400 words): Your hook. This is where you introduce the topic, state your focused research question, explain its significance, and briefly outline the path your argument will take.
  4. Body (approx. 2,500-3,000 words): The main event. This is where you build your argument. It should be logically divided into sections (use subheadings!) where you present evidence, analysis, and evaluation to explore your research question.
  5. Conclusion (approx. 300-400 words): Tie it all together. You should directly answer your research question, summarize your key findings, acknowledge any limitations of your research, and perhaps suggest questions for further investigation.
  6. References and Bibliography: The non-negotiable proof of your academic honesty. You must list every source you've used, following a consistent citation style (like MLA or APA).
The Lanterna Tip: The 4,000-word limit is strict. It includes your introduction, body, conclusion, and any quotations. It does not include the title page, contents page, bibliography, or any appendices. Plan your word allocation carefully from the start!

How the Examiners Grade Your EE: Cracking the Code

Your EE is graded by an external IB examiner against five criteria, totaling 34 marks. Understanding these criteria is the key to writing an essay that scores high marks. Let's translate them from "IB-speak" to plain English.

Criterion & Marks What It Really Means How to Score High Marks
A: Focus & Method
(6 marks)
Is your research question sharp and focused? Did you choose the right methods to answer it? Is your essay structured logically? Spend serious time refining your research question (RQ). It must be a question, not a statement, and shouldn't be answerable with a simple 'yes' or 'no'. A great RQ is the foundation of a great essay.
B: Knowledge & Understanding
(6 marks)
Do you actually know your stuff? Are you using subject-specific language and concepts correctly and in the right context? Show the examiner you've gone beyond the textbook. Integrate academic sources and demonstrate a sophisticated understanding of the topic. You need to sound like a historian, economist, or scientist.
C: Critical Thinking
(12 marks)
This is the big one. Are you just describing facts, or are you analyzing, evaluating, and building a persuasive argument? Constantly ask "so what?". Don't just present evidence; critique it. Discuss its strengths and weaknesses. Acknowledge counter-arguments. This is where your own academic voice needs to shine through.
D: Presentation
(4 marks)
Is your essay formatted professionally? Is it easy to read and follow? Are your citations and references correct? These are the easiest marks to get, and the easiest to lose! Use a standard font, number your pages, create a contents page, and make sure your referencing is flawless and consistent. It shows respect for your work.
E: Engagement
(6 marks)
How did you engage with the research process? This is assessed only on your 500-word Reflections on Planning and Progress Form (RPPF). Do not treat the RPPF as an afterthought! Reflect genuinely on your journey: your decision-making, your challenges, your "aha!" moments, and how your thinking evolved. Tell the story behind the essay.

More Than Just an Essay: The Skills You'll Walk Away With

The EE is a marathon, not a sprint. But crossing that finish line with a piece of work you're truly proud of is an incredible achievement. More importantly, you'll have developed a toolkit of skills that are essential for success in university and your future career.

Academic Power-Ups

You'll master how to formulate research questions, find and evaluate academic sources, and construct a sustained, evidence-based argument. Your academic writing will reach a new level of clarity and sophistication.

Real-World Skills

This is a long-term, independent project. You will become a master of time management, organization, and self-motivation. These are the "soft skills" that employers and universities value just as much as academic knowledge.

Ultimately, the Extended Essay is your chance to prove to yourself, and the world, what you're capable of. Embrace the challenge, choose your topic wisely, and enjoy the journey of becoming a true expert.

The Extended Essay is a core component of the IB Diploma, requiring you to complete an independent, 4,000-word research paper on a topic you choose. It's designed to be your first taste of university-level academic work, developing essential skills in research, critical thinking, and time management that universities highly value.

A great research question is focused, arguable, and researchable within the word limit. Start with a subject you're passionate about, then narrow down your focus. Avoid questions that are too broad or purely descriptive. Many students find this the hardest step, and it's a key area where our tutors help, ensuring your question sets you up for an A-grade from the start.

Most students find Criterion C: Critical Thinking (worth 12 marks) the most difficult. It's not enough to just present information; you must analyse, evaluate, and build a sustained argument. This is where having an expert mentor is invaluable. They can help you structure your analysis and challenge your assumptions to reach the top marks.

While school supervisors are essential, their time is often stretched. Lanterna’s tutors, who are all high-achieving IB graduates, provide personalised, one-on-one guidance. We can help you refine your research question, structure your argument, and master the academic tone required, ensuring you meet every assessment criterion without violating academic honesty rules.

It's a free, 20–30 minute online call with one of our Student Success Experts, who are themselves IB graduates. It’s designed for students and parents to discuss specific challenges, like the EE or exam revision, and map out a clear strategy for success. There is absolutely no obligation to purchase tutoring afterwards.

Yes, completely. We believe in providing value upfront. The goal of the free consultation is to give you a clear plan with priorities and actionable next steps to tackle the Extended Essay or any other part of the IB. You'll leave the call with expert advice, whether you choose to work with us further or not.

Our Student Success Experts are experienced IB graduates who have been through the entire diploma programme. They aren't tutors, but strategic advisors who understand the pressures of the IB. During your free consultation, they’ll listen to your goals and help you create a personalised plan to achieve them with confidence.

The earlier, the better. The initial stages—choosing a subject and defining a strong research question—are critical. Getting expert guidance at this point can save you months of wasted effort. However, we also help DP2 students who are struggling to structure their argument or refine their final draft. A free consultation can help you assess where you are and what you need to do next.

We cover a vast range of IB subjects. Our tutors have written successful Extended Essays across the sciences, humanities, arts, and languages. In your free consultation, we can discuss your specific subject choice and see how our network of expert IB tutors can support your unique project.

You'll receive a follow-up email summarising your personalised plan and next steps. If you decide that tutoring could be beneficial, your Student Success Expert will suggest a potential tutor match and a suitable package. There is never any pressure to buy; the goal is to provide you with clarity and confidence for your IB journey.
