The Extended Essay (EE) in the International Baccalaureate (IB) is graded according to five official assessment criteria set by the International Baccalaureate and can earn a total of 34 points. Together with the Theory of Knowledge (TOK) grade, these points feed into the so-called bonus points matrix and can raise the overall IB score by up to 3 points. The essay is assessed by external IB examiners, not by the student’s own school.
The following questions cover everything students and parents should know about how the Extended Essay is assessed.
How Many Points Can You Earn With the Extended Essay?
The Extended Essay can earn a maximum of 34 points. These 34 points are not added directly to the overall IB score; instead, they are evaluated together with the Theory of Knowledge assessment in a combined matrix that can contribute up to 3 bonus points to the overall score.
The 34 points are distributed across five assessment criteria set by the IB. Each criterion has its own maximum score, and the sum of all criteria makes up the total. This total is then converted into a letter grade from A to E, which, together with the TOK grade, feeds into the bonus points matrix.
According to Which Criteria Is the Extended Essay Assessed?
The IB assesses the Extended Essay according to five criteria: focus and method, knowledge and understanding, critical thinking, presentation, and engagement. Each criterion examines a different aspect of the academic work and contributes a different weight to the total score.
| Criterion | Maximum points | What is assessed |
|---|---|---|
| A: Focus and method | 6 | How clearly the research question is formulated, whether the topic has been narrowed down, and whether the chosen method suits the question |
| B: Knowledge and understanding | 6 | How well the student understands the topic and the relevant academic literature and whether subject-specific terminology is used correctly |
| C: Critical thinking | 12 | The quality of the analysis, argumentation, and conclusions; this is the most heavily weighted criterion |
| D: Presentation | 4 | The formal aspects of the work, i.e., structure, citations, bibliography, and compliance with formatting requirements |
| E: Engagement | 6 | Assessed on the basis of the reflection sessions with the supervisor; shows how seriously and independently the student went through the research process |
What Do the Grades A to E Mean for the Extended Essay?
The letter grades A to E reflect the quality of the Extended Essay on a five-point scale. A grade of A stands for excellent work, while a grade of E indicates insufficient performance and may result in the IB Diploma not being awarded.
In detail, the grades mean:
- A: Excellent work with a clear research question, strong argumentation, and convincing conclusions.
- B: Good work that solidly meets most requirements but still shows room for improvement in some areas.
- C: Satisfactory work with recognizable strengths but also clear weaknesses in analysis or presentation.
- D: Adequate work with significant shortcomings in several assessment areas.
- E: Insufficient work. A grade of E in the Extended Essay or in Theory of Knowledge automatically results in failing the IB Diploma.
How Does the Extended Essay Affect the Overall IB Score?
The Extended Essay affects the overall IB score indirectly through the bonus points matrix. The letter grade for the Extended Essay is combined with the Theory of Knowledge grade, and the result of this combination yields up to 3 additional points that are added to the overall score.
The maximum overall IB score is 45 points: 42 points from the six subjects plus up to 3 bonus points from the Extended Essay and TOK combination. Students who do well in both areas, that is, who achieve at least a B in the Extended Essay and a B in TOK, receive the full 3 bonus points.
A weak performance in either of the two areas can significantly reduce these bonus points. Since many university admissions are tied to minimum overall scores, the Extended Essay can make all the difference.
What Common Mistakes Cost Points in the Extended Essay?
The most common mistakes in the Extended Essay are a research question that is too broad, superficial analysis instead of critical engagement, and formal shortcomings in citations and the bibliography. These mistakes directly affect the most heavily weighted criteria and cost a disproportionate number of points.
Specifically, the following weaknesses recur in weak essays:
- The research question is too broad to be answered conclusively in 4,000 words.
- The essay describes or summarizes instead of analyzing and arguing, which particularly weakens criterion C.
- Sources are cited incompletely or inconsistently, which costs points in criterion D.
- The conclusion introduces new points that were not developed in the main body.
- The reflection session is not taken seriously, even though it directly influences the engagement score.
- The essay exceeds the 4,000-word limit, which requires examiners to ignore everything beyond it.
Who Assesses the Extended Essay: The School or the IB?
The Extended Essay is assessed exclusively by external IB examiners, not by the student’s own school. The supervising teacher at the school accompanies the student during the process, conducts the reflection sessions, and awards the engagement score, but has no influence on the assessment of the written work itself.
This process ensures that the assessment is objective and internationally comparable. The IB’s external examiners are trained in their specific subjects and assess according to the official criteria. The school submits the completed essay digitally via the IB system, and marking is anonymous.
Can Students Request a Review of Their Extended Essay Grade?
After receiving the results, parents and students can request a review if they wish to challenge the assessment. However, a re-mark does not automatically mean a better grade.
