ES
The Extended Essay (EE) is a mandatory core component of the International Baccalaureate (IB) Diploma Programme (DP). It is one of the three elements of the IB core, alongside Theory of Knowledge (TOK) and Creativity, Activity, Service (CAS).
The Extended Essay is an independent academic research project that students undertake individually, under the guidance of a supervisor. Its primary purpose is to develop essential skills in research, critical thinking, and academic writing—key tools for success at the university level.
In the IBDP Extended Essay, the student selects a topic of personal interest within one of the DP subjects, formulates a clear and focused research question, and writes an essay of up to 4,000 words. This essay must explore the question in depth, using a structured and evidence-based approach. Throughout the process, the student participates in supervised reflection sessions, which are documented in the Reflections on Planning and Progress Form (RPPF). This supports the development of self-management and metacognitive skills.
The Extended Essay can be completed in both face-to-face settings and in the IBDP Online format.
Why is the Extended Essay important in the IBDP?
The Extended Essay (EE) is more than an academic requirement—it is a transformative learning experience that prepares students for the challenges of university life. Through the EE, students develop:
- Critical thinking: By evaluating sources, constructing well-supported arguments, and questioning assumptions.
- Research skills: Including the use of academic databases, organizing bibliographies, and applying proper citation techniques.
- Time management: As the process unfolds over several months, students learn to plan and meet key deadlines.
- Academic writing proficiency: The formal structure and academic language of the essay prepare students for university-level research.
Furthermore, the Extended Essay contributes up to 3 additional points toward the maximum 45 points of the IB Diploma, when combined with the TOK grade. These extra points can be crucial in achieving the full diploma.
How is the Extended Essay assessed?
The Extended Essay is externally assessed, meaning it is marked by official IB examiners, not by school teachers. It is graded on a scale from A (highest) to E (lowest). The assessment criteria include:
- Focus and Method: Clarity of the research question, relevance of the topic, and planning.
- Knowledge and Understanding: Depth of understanding of the topic and subject-specific context.
- Critical Thinking: Quality of analysis, evaluation of evidence, and coherence of argument.
- Presentation: Structure, formal presentation, citation style, and references.
- Engagement: Evaluated through the RPPF, reflecting the student’s personal engagement and insights throughout the research process.
These criteria together determine the EE final grade. A well-developed Extended Essay not only improves a student’s chances of earning higher points but also serves as a strong foundation for future academic research.
Where to find topics for the Extended Essay?
Selecting a suitable topic is crucial for the success of the Extended Essay. Ideally, it should be an area of genuine personal interest, since students will be exploring it over several months. Strategies to identify a good topic include:
- Reviewing DP subject content: Topics must be aligned with one of the approved IB subjects, so class materials are a logical starting point.
- Exploring personal interests: A hobby, social concern, or intellectual curiosity can evolve into a compelling research question.
- Consulting past Extended Essays: Reviewing previous samples helps clarify expectations regarding depth and rigor.
- Speaking with teachers and supervisors: They can help identify viable topics and point to relevant resources.
- Using academic databases and digital libraries: These provide access to reliable sources that support the research process.
Examples of IB Extended Essays
Below are real examples of Extended Essays written by IB students in different subjects:
- Biology EE example: To what extent does prolonged sun exposure affect leaf pigmentation in Coleus blumei?
- History EE example: To what extent did U.S. intervention in Chile during the 1970s contribute to the overthrow of Salvador Allende?
- Literature EE example: A comparative analysis of the representation of female oppression in Federico García Lorca’s “The House of Bernarda Alba” and Gabriel García Márquez’s “Chronicle of a Death Foretold”.
- Economics EE example: What was the impact of the COVID-19 pandemic on small and medium-sized enterprises in the food industry in Mexico City?
