The Extended Essay is 4,000 words, marked by an external IB examiner, and contributes up to three bonus points to your Diploma total through the EE and TOK matrix. Understanding how it is evaluated before you begin writing is the single most important thing you can do to maximise your grade.

The Grades and Points Matrix

The Extended Essay is graded A to E. Combined with your Theory of Knowledge grade on the same scale, the two produce bonus points:

• A in EE and A in TOK: 3 bonus points
• A in one, B in the other: 2 bonus points
• B in both: 2 bonus points
• C in both: 1 bonus point
• E in either EE or TOK: Automatic Diploma failure, regardless of all other results

The Extended Essay deserves the same seriousness as any examined subject. At the top end, it adds three points equivalent to moving a subject grade from 6 to 7. At the bottom end, it can fail your Diploma entirely.

The Five Assessment Criteria

Criterion A: Focus and Method (6 marks)

Assesses the clarity and appropriateness of your research question, your research design, and the context you have provided. A strong research question is specific, arguable, and genuinely investigable in 4,000 words. Questions using “to what extent” invite argument and analysis rather than description, which is almost always stronger.

Criterion B: Knowledge and Understanding (6 marks)

Assesses how well you demonstrate understanding of the topic and subject area, including use of subject-specific terminology and awareness of relevant theoretical frameworks. Examiners can tell the difference between a student who has read widely and deeply and one who has read just enough to produce 4,000 words.

Criterion C: Critical Thinking (12 marks)

The highest-weighted criterion. Assesses the quality of your analysis, evaluation of sources, development of your own argument, and depth of conclusions. The essays that score highest on Criterion C are those where the examiner can see the student’s own thinking, not just a summary of what others have said. Essays that are primarily descriptive score lowest here regardless of how well-written they are.

Criterion D: Presentation (4 marks)

Assesses structure, layout, citation formatting, and the quality of the bibliography and visual elements. Students frequently lose marks here for avoidable reasons: inconsistent citation formatting, a bibliography listing sources not used in the essay, and unlabelled visuals.

Criterion E: Engagement (6 marks)

Assessed through the Reflections on Planning and Progress Form (RPPF), a 500-word document recording reflections at three mandatory checkpoints. Strong Criterion E shows genuine intellectual evolution: what surprised you, how your thinking changed, what you would do differently. Reflections written in the same week as the essay are immediately visible to examiners.

At JBCN School, RPPF entries are scheduled as part of the Extended Essay calendar, with structured reflection prompts at each checkpoint. Students write genuine reflections over time rather than reconstructing them at the end.

Choosing the Right Subject and Research Question

The subject and research question are the two decisions that most significantly determine quality before a single word is written.

• Subject choice should be guided by genuine interest and the subject in which you are most capable of independent academic work at a high level.
• A well-formed research question is specific enough to investigate in 4,000 words, invites analysis rather than description, is situated in a real academic debate, and is answerable using sources you can actually access.

At JBCN, research question development is supported through a structured workshop process in Grade 11. Students propose initial questions, receive feedback from their supervisor, refine based on preliminary research, and arrive at a final question that has been genuinely tested before writing begins.

The Viva Voce

A ten to fifteen minute conversation between the student and supervisor after submission. It is not assessed separately but contributes to Criterion E via the final RPPF reflection. Students who have genuinely engaged with their topic find the viva voce natural. At JBCN, supervisors are trained to ask open questions that invite honest reflection rather than testing recall of specific content.

What JBCN Does

At JBCN School, the Extended Essay process begins in Term 2 of Grade 11. Students work with a nominated supervisor with a structured meeting schedule built into the school calendar. Draft feedback is provided against the published IB criteria with specific, criterion-referenced comments. The outcomes are reflected in JBCN’s EE results, which show a meaningful proportion of students achieving A and B grades.

The Bottom Line

The Extended Essay adds up to three bonus points, demonstrates genuine intellectual capability, and produces work students are often genuinely proud of. The difference between a strong and weak EE is almost entirely determined early: choosing the right subject, developing a strong research question, and engaging genuinely with the research process from the beginning.
