The IB Extended Essay is one of the most demanding pieces of writing your child will produce before university. Indeed, it is a 4,000-word independent research essay across any subject they choose. However, the path to an A is rarely about working harder. Students who get an A in the IB Extended Essay do something specific. They choose a focused research question, build a supervisor relationship from the start, document their thinking carefully, and structure the argument with academic precision.
This guide explains how to get an A in the IB Extended Essay. Specifically, we cover the five assessment criteria, choosing a subject and research question, the supervisor relationship, the Reflections on Planning and Progress Form (RPPF), and the Researcher’s Reflection Space (RRS). Whether your child writes an EE in English, history, biology, mathematics, or any other subject, the strategies below apply.
Where the A actually comes from
Most EE students at the B-to-A boundary have the content. The A comes from a sharp research question, structured argument, careful documentation in the RPPF, and a clear voice that demonstrates genuine engagement with the topic.

What is the IB Extended Essay actually assessed on?
The IB Extended Essay is marked across five criteria, each carrying significant weight. Specifically, your child’s final grade depends on how they perform on every criterion, not solely on the essay itself. Therefore, understanding the marking framework is the foundation for getting an A.
The five assessment criteria
Criterion A (Focus and Method) tests the research question, methodology, and scope. Knowledge and Understanding (Criterion B) covers subject-specific knowledge and terminology. Importantly, Critical Thinking (Criterion C) is the heaviest criterion at 12 marks, assessing analysis, evaluation, and argument. Furthermore, Criterion D (Presentation) covers structure, layout, and referencing. Engagement (Criterion E) is assessed through the RPPF and measures genuine intellectual engagement with the research process. Notably, the criteria total 34 marks, and an A typically requires 27 or more.
How the EE affects the IB Diploma score
The Extended Essay sits alongside Theory of Knowledge in the IB Diploma core, and the two together can earn up to 3 bonus points. Specifically, an A in the EE plus an A in TOK gives 3 points. In contrast, an E in either component fails the entire Diploma. Therefore, the EE is a high-leverage piece of work. As a result, families with strong predicted IB scores often invest in EE support because gaining 2 to 3 bonus points can move a 41 to a 44, which changes university outcomes materially.

How to choose the right IB Extended Essay subject and research question
The single biggest decision in the EE is the research question itself. Indeed, a strong research question makes the rest of the process much smoother. In contrast, a weak research question leads to weeks of wasted work and a capped grade.
Pick the subject your child loves, not the easiest one
Students often choose their EE subject based on what feels safe rather than what excites them. However, the Engagement criterion (Criterion E) rewards genuine intellectual curiosity. Specifically, students who pick a topic they care about write better RPPF reflections and produce stronger essays. For example, a student passionate about climate science will write a more compelling EE in environmental systems than in mathematics, even if maths is their strongest subject. Furthermore, the EE is a 4,000-word commitment over many months. Genuine interest is the only sustainable motivation.
Crafting a research question that earns marks
The most common EE mistake is choosing a research question that is too broad. For example, “How does climate change affect biodiversity?” cannot be properly investigated in 4,000 words. In contrast, “To what extent has rising sea temperature affected the abundance of Atlantic cod stocks in the Barents Sea since 2000?” is sharp, specific, and answerable. Specifically, a 7-scoring research question is focused, analytical, and clearly subject-specific. Furthermore, tutors who have marked or moderated EEs spot a doomed research question early and help your child refine it before they write a single word of the main body.
How to get an A in the IB Extended Essay through the supervisor relationship
Every EE student is assigned a supervisor from their school. Specifically, the supervisor provides three formal reflection sessions and informal guidance throughout the process. Notably, the quality of this relationship has a direct impact on the final grade. As a result, students who manage their supervisor well consistently outperform those who treat the relationship as a formality.
The three reflection sessions matter
The first reflection session establishes the research question and methodology. The second mid-point reflection reviews progress and addresses problems. Furthermore, the final viva voce is a conversation about the finished essay and the research journey. Specifically, each session is documented on the RPPF (Reflections on Planning and Progress Form), which the examiner reads as part of the Engagement criterion. Therefore, your child should walk into each session with specific questions, draft material, and evidence of their thinking. Vague sessions waste the opportunity.
When external tutoring helps
Supervisors are usually teachers within the school who manage many other commitments. As a result, the level of attention each student receives varies significantly. Specifically, an external tutor brings dedicated EE expertise and weekly feedback that schools often cannot match. For instance, a tutor can read full drafts, flag structural issues, and rebuild weak arguments in ways that a busy supervisor may not have time to do. Furthermore, the tutor never replaces the supervisor. Instead, they work alongside the school relationship to strengthen the final essay.
How to get an A in the IB Extended Essay through the RPPF and RRS
The Reflections on Planning and Progress Form is worth 6 marks under Criterion E. Specifically, your child writes three reflections totalling 500 words across the EE process. Notably, the RPPF is the single most underestimated component of the entire EE. As a result, students who treat it as an afterthought lose easy marks they could have banked with minimal additional work.
What examiners look for in the RPPF
Top-band RPPF reflections show genuine intellectual development. Specifically, examiners look for evidence that your child has wrestled with the research process: methodological challenges, dead ends, breakthroughs in thinking, sources that changed direction. In contrast, generic reflections that describe “what I did this week” cap at a 3 out of 6. Furthermore, the RPPF must be written in the first person and demonstrate critical self-awareness. For example, a strong reflection might note that initial assumptions were challenged by a counterargument in the literature, leading to a refined research question.
Keeping a Researcher’s Reflection Space
The Researcher’s Reflection Space is not formally assessed, but it feeds directly into the RPPF and the viva voce. Specifically, the RRS is a personal journal where your child records sources read, ideas considered, methodological problems, and conversations with the supervisor. Indeed, students who keep a thorough RRS write better RPPFs because they have detailed material to draw on. In contrast, students who try to invent reflections at the end of the process produce thin, generic responses. Therefore, your child should begin the RRS in the first week of the EE process and update it weekly throughout.
How to structure the IB Extended Essay for an A
A 4,000-word essay needs careful structural planning before the writing begins. Specifically, the EE follows a standard academic structure with subject-specific variations. Notably, structure carries marks under Criterion D (Presentation), but it also affects how clearly the argument lands under Criterion C (Critical Thinking).
The essential structural elements
Every EE includes a title page, contents page, introduction, body, conclusion, and references. Specifically, the introduction establishes the research question, methodology, and scope. The body develops the argument through evidence and analysis. Furthermore, the conclusion answers the research question directly and acknowledges limitations. Importantly, the EE is capped at 4,000 words for the body. Examiners stop reading at exactly 4,000 words, so your child must be ruthless with cuts. Indeed, students who exceed the word count lose entire paragraphs of argument from the marking.
Referencing and academic honesty
Top-band EEs reference rigorously. Specifically, every claim drawn from a source must be cited, and every source must appear in the bibliography. Your child should pick one referencing system (MLA, APA, Chicago, or Harvard) and apply it consistently. Furthermore, the IB takes academic honesty extremely seriously. Indeed, plagiarism, AI-generated content, and unattributed paraphrasing can result in the EE being failed and the IB Diploma withheld. As a result, your child should keep careful records of every source consulted, ideally through a reference manager like Zotero.
Which Oxbridge tutors help students get an A in the IB Extended Essay?
The right tutor lifts an EE grade from a B to an A in the final months of the process. They diagnose where the argument is weak, sharpen the research question, and model the kind of academic writing the examiner rewards. Below are two Greenhill tutors who work with IB families on the Extended Essay across humanities subjects.
Laurie
Laurie holds a Double First in English Language and Literature from The Queen’s College, Oxford. Notably, he supports IB students on the Extended Essay as a core part of his tutoring. He has 500+ hours of tutoring experience and has helped students secure places at Oxford, Cambridge, Johns Hopkins, and Stanford. Laurie works as a foreign correspondent alongside tutoring, bringing real-world academic writing expertise to every session. His structured approach to argument and evidence works particularly well with EE students aiming at the top band.
Sneha
Sneha graduated from the University of Cambridge with a First-Class Distinction in English Literature. She has extensive experience teaching IB students across HL and SL English Literature, including students undertaking Extended Essays in English. Her teaching combines deep textual analysis with practical academic writing technique. This works particularly well for EE students who need help refining a research question or restructuring an argument across the full 4,000-word essay.
When should your child start IB Extended Essay tutoring?
The earlier your child builds the right habits, the smoother the EE process becomes. In general, most families benefit from starting tutoring in Year 12 (DP1) when the research question is being chosen. Specifically, the right moment is before the first reflection session with the supervisor, so the research question is already sharp. A tutor at this stage helps avoid the common dead ends. Furthermore, they introduce the RRS practice early and build academic writing technique well before the first draft.
Year 13 (DP2) students can still lift an EE grade with a focused block of weekly sessions. Indeed, six to ten weeks is often enough to move a B to an A if the research is sound but the writing needs work. The key is choosing a tutor who can read full drafts quickly. They should give specific feedback on argument structure, evidence use, and the RPPF reflections. For families thinking ahead to UK university applications, the same tutor often supports admissions, including personal statements and interview preparation.
