IB Extended Essay Tutor | IB Tuition | Leading Tuition

The Extended Essay is a 4,000-word independent research essay submitted as part of the IB Diploma. It is assessed externally by IB examiners — not your school — against five criteria covering focus and method, knowledge and understanding, critical thinking, presentation, and engagement. The essay is graded from A to E, and combined with your Theory of Knowledge grade through a matrix that awards up to three bonus points toward your final Diploma score. Those points can be the difference between a 42 and a 45, or between passing and failing the Diploma altogether if an E grade is awarded in either component.

The essay is written over roughly eighteen months, from initial topic selection in the first year of the Diploma through to final submission in the second. Your school will assign a supervisor, but their role is limited — typically three formal reflection sessions. The research, the argument, and every word of the essay must be your own.

What the Extended Essay Requires

The Extended Essay demands something most IB students have not yet been asked to do: frame an original research question, pursue it independently across primary and secondary sources, and construct a sustained analytical argument over 4,000 words. It is not a long essay in the style of an internal assessment. It requires genuine intellectual ownership — a specific question that is genuinely answerable within the scope of the word count, and an argument that develops rather than describes.

The subject you choose shapes the methodology expected. A History essay requires engagement with historiography and source evaluation. A Biology essay requires primary data or rigorous analysis of existing data. A Literature essay requires close textual analysis. Examiners assess whether your approach is appropriate to the discipline, not just whether your writing is competent.

Where Students Most Often Go Wrong

The most common and most damaging failure is a research question that is too broad or too descriptive. A question like "What were the causes of the First World War?" cannot be answered analytically in 4,000 words — it produces a narrative summary that scores poorly on critical thinking regardless of how well it is written. The question must be focused enough to permit genuine argument.

• Overly broad research questions that lead to descriptive rather than analytical essays
• Weak engagement with sources — summarising what sources say rather than evaluating their significance, reliability, or limitations
• Absent or underdeveloped argument — presenting information without a clear line of reasoning that the essay is actively defending
• Poor structure — sections that do not connect logically, or a conclusion that simply restates the introduction
• Presentation errors — missing or incorrectly formatted abstract, bibliography, or citations, which cost marks directly under Criterion D
• Process failure — leaving the bulk of research and writing to the final months, which produces rushed, underdeveloped work

How the Assessment Is Marked

IB examiners mark the Extended Essay against five criteria, with a total of 34 marks available. Criterion A (Focus and Method) and Criterion C (Critical Thinking) carry the most weight — 6 marks each — and both reward the same underlying quality: a precise, well-reasoned approach to a genuinely researchable question. Criterion B (Knowledge and Understanding) awards up to 6 marks for demonstrating subject-specific understanding and appropriate use of terminology. Criterion D (Presentation) awards up to 4 marks and covers formal requirements including structure, layout, and referencing. Criterion E (Engagement) awards up to 6 marks and is assessed through your Reflections on Planning and Progress form, not the essay itself — making the process documentation a graded component in its own right.

An A grade requires strong performance across all five criteria. Students who focus only on writing quality and neglect the research question, the methodology, or the reflection form consistently underperform relative to their ability.

How Tuition Helps — and What It Cannot Do

A Leading Tuition tutor works with you at every stage of the process: refining your research question until it is genuinely focused and answerable, planning an argument structure before you begin writing, identifying relevant and credible sources, and reviewing drafts to improve analytical depth, clarity, and expression. Tutors with subject expertise can identify where your reasoning is underdeveloped, where your engagement with sources is superficial, and where your argument loses coherence — and explain how to address each of these problems.

What a tutor cannot do is write any part of the essay for you. The IB's academic integrity policy is explicit, and the work submitted must be entirely your own. Our tutors are Oxford and Cambridge graduates who understand the difference between developing a student's thinking and doing their thinking for them. Every session is directed at building your understanding and your skills — so that the essay you submit is genuinely yours, and genuinely strong.

Frequently Asked Questions

Can a tutor help me choose my Extended Essay subject and topic?

Yes. A tutor can help you evaluate potential subjects and topics against the key criteria: whether a focused research question is achievable, whether appropriate sources exist, and whether the subject plays to your strengths. Choosing well at this stage has a significant effect on the final grade.

My research question has already been approved by my supervisor — is it too late to refine it?

Supervisor approval does not mean a question is optimally focused for high marks. Many approved questions are still too broad or too descriptive. A tutor can work with you to sharpen the question within your chosen subject area, and most supervisors welcome a more precise formulation.

How many sessions does the Extended Essay typically require?

This depends on where you are in the process and how developed your draft is. Students starting from topic selection typically benefit from four to six sessions spread across the research and writing period. Students with a draft already in progress often need two to four focused sessions on argument development and revision.

Does tuition cover the Reflections on Planning and Progress form as well as the essay?

Yes. The RPPF contributes to Criterion E and is assessed by examiners, so it warrants the same care as the essay itself. A tutor can help you understand what genuine critical reflection looks like in this context and how to document your research process effectively.
