What Is the Extended Essay (EE)?

The Extended Essay is a 4,000-word research paper that you must complete as part of the IB Diploma. It’s an independent piece of academic work that allows you to dive deep into a subject you're passionate about, conducting detailed research and presenting your findings in a structured manner. It’s an opportunity to showcase your critical thinking, research skills, and ability to write a comprehensive academic paper.

Why Does Your Extended Essay Topic Matter?

Your topic is the foundation of your Extended Essay. A strong, focused, and well-researched topic not only makes the process easier, but it also increases your chances of getting a top grade. But how do you choose the right topic?

Here are a few tips:

  • Passion & Interest: Choose something that excites you. You’ll spend months researching and writing it, so make sure it’s something you care about.

  • Scope: The topic should be narrow enough to research thoroughly in 4,000 words but broad enough to offer plenty of material to work with.

  • Relevance: The topic should be related to your IB subject and course objectives.

  • Researchability: Ensure there are enough sources available to support your research.
